Nowadays, the construction of one-story premises, both residential and industrial, is very popular. In most cases, these are garages, bathhouses, small buildings near the house. Each of the newly minted builders, of course, is looking for all sorts of ways to save their money without losing quality, because basically everything is done for themselves.
So, among the huge selection of building materials, we will focus on the most profitable at the moment - cinder block.
Homemade building material
The cost of cinder blocks is low, and in size they replace about 5 ordinary bricks; there are products equal to 8-10 ceramic blocks. They are made from any available material, also called aggregate.
Fillers include:
- Sand.
- Expanded clay.
- Ash.
- Slag.
- Sawdust.
- Crushed stone.
- Broken brick.
Note!
The choice should be made depending on how high quality and durable you want the product to be.
For residential buildings it is better to use expanded clay, slag or sand, and for utility buildings ash and sawdust are suitable.
The strengthening element is based on cement. When making cinder blocks yourself, you not only reduce the cost of future construction, but have full control over the quality of the material produced. You can also choose the shape of future blocks yourself.
As for the equipment, it’s worth looking at the drawings of the machine for cinder blocks and unnecessary questions will immediately disappear. You don’t have to be a construction genius to make your own machines at home, that’s what we’ll tell you about in our article.
You can easily find homemade machines for cinder blocks on the Internet, made by “masters” like you, so don’t doubt your abilities.
Important!
Before starting work, familiarize yourself with the possible variations in the dimensions of the building material.
If you want to make a block of a standard shape, then it has the following parameters -400 × 200 × 200 mm.
As for voids, they make up no more than 30% of the total volume.
Manufacturing of the machine
Machines for cinder blocks are sold in a wide range, their prices vary from 3-4 thousand rubles to several tens.
But, since today we are talking about self-production, we will start by determining for what scale you need such a machine:
- If you need to make a small building, then a machine for the simultaneous production of one or two blocks is perfect for you.
- If you want to put this on the conveyor belt, then you need to make a matrix of four or even more blocks.
What does the equipment consist of?
Having decided how many cinder blocks you want to produce per day, let's look at the structure of this machine:
- The most important part in the machine is the matrix, so you need to pay special attention to this stage of manufacturing. After all, the shape, accuracy and dimensions of future cinder blocks will depend on it in the future.
Note!
All other components of the unit are intended only to simplify the use of such a machine, these are filling, compaction, extraction, movement.
Although each process is important in its own way for a positive final result.
- There are several methods for compacting the solution; the most suitable and easiest to manufacture is an electric motor with a displaced center of gravity to create vibration. The motor is attached directly to the mold (matrix) and must be covered with casings. A shift in the center of gravity can be achieved by welding a bolt and nut perpendicularly to the engine shaft.
For your information!
To understand how this all happens, look at the photo below. They show drawings of a vibrating machine for cinder blocks.
How to do it yourself
Knowing the dimensions of the desired block, we proceed to manufacturing the matrix:
- Blanks are cut from sheet metal with a thickness of 3–5 mm.
- To make voids in a block, you will need a void former, which can be made from pipes of the required diameter. It is advisable to use tapered pipes to facilitate removal from the finished block. At your discretion, you can use not only pipes, but also rectangular void formers, the main thing is not to forget to make them cone-shaped.
- We connect the workpieces using tacks, since a continuous seam can lead to metal leaking.
Note!
Seams are made only on the outside of the mold, otherwise the block will not have the correct geometric shape.
- The height of the form should be 5 cm higher than the dimensions of the finished block. This is due to the fact that during vibration the mixture tends to be compacted, and also for installation on top of a pressure sheet.
- The next stage is the frame. To make it easier to move the machine, the base is placed on wheels, which allows you to move the machine without disturbing the finished block. It is recommended to make the racks on which the form will walk a little longer, so to speak with a margin, because you will always have time to cut it off - for convenience. All mechanisms and parts are made according to individual preference, and based on your height.
The use of cinder blocks in construction can reduce the cost of constructing walls several times. To produce this material, special equipment is required, the purchase of which is quite an expensive process. We suggest you study the recommendations on how to make a machine for cinder blocks with your own hands.
Cinder block - features of the material and its purpose
Cinder block is a building material that is similar in appearance to stone, which is made using the vibrating press method. For its production, a filler in the form of slag is used, and the binder is cement mortar.
There are two options for producing cinder blocks:
- industrial;
- independent or home.
To make cinder blocks with your own hands, small-sized vibrating machines are used, which are capable of producing small batches of this material.
In relation to the main components of the cinder block, namely slag, it contains one of the materials in the form of:
- slag;
- volcanic ash;
- granite screenings;
- crushed granite;
- river crushed stone;
- sand;
- brick stone;
- cement;
- expanded clay, etc.
The material, the manufacture of which we will discuss further, has lower quality characteristics and durability. It is perfect for the construction of utility buildings, sheds, and storage buildings.
Homemade cinder block production does not allow the entire technological process to be carried out in accordance with all the requirements that are placed on it.
In order for the cinder block to acquire the necessary rigidity, it is necessary to withstand steaming, through which it is saturated with moisture and heated to a certain temperature, which increases the strength of the cement. Although, with the help of blocks made on a home vibrating machine, you will get an excellent one-story building, the service life of which will be at least 25 years.
Machine for cinder blocks: manufacturing features
To build this kind of machine, you must have skills in working with a welding machine and metalworking tools.
The main part of a homemade cinder block machine is a matrix, which has a shape for installing a solution. The matrix has the form of a metal box in which there are certain elements that provide voids in the already manufactured product.
It is the matrix that is a kind of machine, the manufacture of which will require the presence of:
- welding machine;
- Bulgarians;
- vice;
- metalworking tools.
The materials you will need to purchase are:
- sheet of metal, 3 mm thick, 1 m² in size;
- one meter of steel pipe, with a diameter of 7.5 to 9 cm;
- steel strip 3 mm thick and 30 cm long;
- electric motor, power up to 0.75 kW;
- fasteners in the form of bolts and nuts.
Instructions for making a cinder block machine with your own hands:
1. First, decide on the dimensions of the product that is needed for construction. It is possible to measure a ready-made industrial cinder block.
2. Cut out the side sections of the machine from a metal sheet; there should be two of them, and there should be a partition between them. The result is a box having two equal parts.
3. A bottom wall remains in the voids, the thickness of which is at least 3 cm. Thus, it will be possible to determine the height of the cylinder that will limit the voids.
4. Cut the pipe into six pieces, the length of which will be equal to the height of the void.
5. To make each of the cylinders cone-shaped, it is necessary to make cuts in each of them to the center, and then compress them using a vice and weld them together by welding. In this case, the diameter size will become two millimeters smaller.
6. Weld the cylinders on both sides and connect them together on the long side of the block. They must be located in such a way that the voids that will be formed exactly copy the voids of industrial production.
7. A plate 3 cm in size is added to the extreme sections. It must have a hole that will ensure its fixation on the surface of the eyes.
8. On the central part of each matrix compartment, saw through the surface and weld lugs to it. They will help provide the ability to temporarily attach restraints to create a void. The result will be a mechanism with the help of which cinder blocks will be produced as a monolithic or non-monolithic type.
9. Select one transverse wall onto which to weld four bolts. They act as fasteners to secure the motor.
10. On the side of loading the mixture, parts in the form of an apron and blades should be welded.
11. Clean and polish all components for further painting.
12. Make a press, the shape of which will be exactly the same as the mechanism itself. To construct it, you will need a plate whose holes will be four millimeters larger than the diameter of the cylinder. It should easily fit into the box to a height of at least 5 cm.
13. To ensure ease of use of the press, weld parts in the form of handles to it.
14. Cover all components of the mechanism with an anti-corrosion primer, and after it dries, install the motor.
In order to make a vibration motor from a standard electric motor, welded bolts in the form of eccentrics should be installed on its shaft sections. They must coincide in axial space. Nuts are installed on the bolts, the amount of tightening of which determines the speed and type of vibration.
Drawings of a cinder block machine:
Using such a matrix, both walking and distance type machines are manufactured. To improve it, you need to have a good mechanic's tool and experience working with it.
Any material in the form of clay, sawdust concrete, expanded clay concrete, etc. is suitable for the manufacture of this kind of blocks. The standard mixture should consist of one part sand filler, one part cement and three parts slag waste.
A very important role is played by the moisture coefficient contained in the finished mixture. To optimally determine it, it is enough to inspect the composition; it should not fall apart, but at the same time it should be elastic and hold its shape well.
It is this kind of workpiece that is placed in the matrix to obtain the finished cinder block. To create voids, it is recommended to use glass bottles, broken bricks or sharp-edged stones.
Please note that before starting work on the machine for producing cinder blocks, all parts should be lubricated with oil, this will prevent the finished mixture from sticking to the metal. Turning on the vibrator is possible at any stage of production, but it is best to do this before pressing the finished block. In addition, the electric motor should be reliably insulated, using an apron to prevent the solution from getting on the surface of the motor.
Ready-made cinder blocks should be kept outdoors, in summer, at temperatures from +12 to +30 degrees. To prevent the blocks from drying out, they are covered with plastic wrap.
Equipment for the production of cinder blocks and their manufacturing technology
The production of cinder blocks begins with the preparation of a concrete solution, which consists of cement, water and slag. All components are mixed together using a concrete mixer or mixer. Manual mixing of the solution takes longer and requires enormous physical effort to carry it out.
All work is carried out exclusively at above-zero air temperatures, since frost causes water to solidify. When the solution is ready, it is poured into a mold, which can be hollow or monolithic. The standard size of each block is 39x19x18.
When the block already has a compacted structure, the mold is removed from it, and the block itself is installed on the floor or on a pallet. The cinder block drying procedure lasts at natural air temperature, which should not be less than twenty degrees. In this way, it will be possible to obtain material suitable for further construction. To avoid drying out of the material, ensure maximum air humidity.
After the cinder blocks dry, they acquire additional strength and are stored in a dry place in the form of a warehouse.
Materials of various compositions are used as raw materials. The choice of one or another raw material is influenced by the capabilities of the equipment on which the cinder block is made and the type of structure that will be erected from it.
The most common options for fillers for making cinder blocks with your own hands are materials in the form of:
- brick waste;
- sand;
- crushed stone;
- ash;
- expanded clay, etc.
The amount of a particular ingredient depends on the requirements for the final product.
A fairly common component for the manufacture of cinder blocks is a plasticizer, which improves the technical characteristics of the finished material. In addition, the use of plasticizers increases the strength of the finished building and its resistance to frost and moisture.
After the production of cinder blocks, the process of construction and the actual construction of walls from cinder blocks awaits. Another important factor influencing the quality of a cinder block structure is the finishing and insulation of the finished building.
The standard composition for preparing a mixture for cinder blocks consists of:
- one part of cement;
- nine parts of slag;
- 50% of the amount of cement is water.
Another option for making cinder blocks involves using:
- four parts of fine screenings;
- four parts granite slag;
- one part cement to 50% water.
Production of cinder blocks - general requirements for the work
To make a high-quality cinder block, you should adhere to the following rules:
- know the exact recipe and composition of the mixture;
- follow the technology of making cinder blocks;
- have sufficiently professional equipment.
In addition, the key to a high-quality cinder block made at home is the use of coarse sand, blast furnace slag, and high-quality cement with a minimum grade of 400. In addition, special equipment is required, including a brick press.
Burnt coal, which is used as a filler, is excellent for making slag. One of the important requirements for the production of cinder blocks is compliance with the symmetrical and even geometric shape of the finished product. Since the amount of mortar required for the construction of the finished building depends on the number of irregularities and flaws in the cinder block. To avoid the appearance of this defect, the mold should be filled to the top and even more, since when vibration is carried out, the finished mixture is compacted and reduced in size.
The vibration form is turned on every time with an interval of 6-15 seconds. Next, vibration is stopped and the finished product is evaluated. If the solution is lower than the outermost line of the matrix, then a pressure cap is installed on it and the vibration is turned on again. Next, the clamp rests against the limiter, the vibration is turned off, and the form is pulled out from the device.
DIY cinder blocks: manufacturing instructions
When making cinder blocks yourself, you should select the composition of the mixture based on the type of cinder block machine. Since the quality of vibration directly determines the properties of the final product.
We offer a variant of the standard recipe for making cinder blocks:
- seven buckets of slag filler;
- two buckets of sand;
- two buckets of gravel;
- one and a half buckets of cement;
- from one and a half to three buckets of water.
Please note that the amount of water affects the structure and quality of the blocks. The solution should not spread after pressing. If you throw the finished mixture on the ground and at the same time it spreads, and in your fist it comes together again, then this type of solution is suitable for making cinder blocks.
If a room is used for making cinder blocks, then it must have a flat floor and good ventilation, but still, it is recommended to make cinder blocks outdoors.
Homemade machines for cinder blocks involve the production of this material according to the instructions below:
1. Pour the solution into the cinder block mold. Turn on the vibrator for five seconds. If the amount of solution is insufficient, add a little more mixture. Set the clamp and turn on the vibrator again. When the clamping device is on the stops, the manufacturing process is considered complete.
2. The vibrating mold is turned on for another 8 seconds and then the mold is removed without turning off the vibrator.
3. Drying the blocks takes a period of four to nine days. Full strength is achieved after a month. The main conditions for their storage are high humidity and temperature.
4. Transportation of blocks to the premises occurs at least a day after their manufacture. If there is a plasticizer in the composition for preparing cinder blocks, their transportation occurs six hours after production.
5. Cinder blocks are stored in the form of a pyramid. After a few months, they become suitable for construction.
This article is intended for those who are interested in maximizing the cost of building materials. From it you will learn about the method of making cinder blocks with your own hands using a vibrating machine. We will talk about how to create a matrix for blocks yourself and about the rules for making blocks for walls.
Cinder block is the simplest and most affordable of stone materials for walls. Its history goes back more than 100 years, and the combination of properties of structural and insulating material makes it indispensable today.
Massive private construction in the periphery, especially in subsidiary plots and farms, requires a constant reduction in the costs of constructing non-residential premises. For the walls of sheds, barns and storerooms, almost everything that comes to hand is used - from slab to marl. In this article we will look at the possibility of creating a vibrating machine for making cinder blocks.
Note. To manufacture the machine, you will need the skills of a welder and mechanic.
Purpose of homemade cinder block
It should be noted right away that the final product will not have high levels of strength and durability compared to factory “prototypes”. Home production does not allow the technology to be maintained, since there is no possibility for a steaming procedure, in which the material is saturated with the necessary moisture and receives the optimal temperature for the reaction of the binder (cement). However, the blocks are quite suitable for the construction of lightweight one-story buildings with a service life of about 30 years.
Cinder block machine
The main part of a homemade machine is the matrix or mold for the raw material mixture. Essentially, it is a steel box with elements installed in it in the form of voids, or without them. The matrix itself is already a machine that can be used by performing some of the operations manually.
To make the machine you will need:
- Welding machine.
- Bulgarian.
- Vise.
- Locksmith tool.
Materials:
- Steel sheet 3 mm - 1 sq. m.
- Pipe Ø 75-90 mm - 1 m.
- Strip 3 mm - 0.3 m.
- Electric motor 500-750 W.
- Bolts, nuts.
Operating procedure:
- Take dimensions from a standard cinder block (w/w) or determine the dimensions you need for yourself.
- Cut out the sides of the matrix from the sheet at the rate of 2 pieces with a partition in the middle. You should end up with a box with two equal compartments.
- The voids should be left by a bottom wall with a thickness of at least 30 mm. From this calculation we determine the height of the cylinder (or parallelepiped) to limit the voids.
- We cut 6 pieces of pipe with a length equal to the height of the cylinder.
- To give the cylinders a cone shape, you need to cut each of them lengthwise to the middle, compress it with a vice and connect it by welding. The diameter will decrease by 2-3 mm.
- Weld the cylinders on both sides.
- Connect the cylinders together in a row along the long side of the block. They must copy the location (pitch, diameter) of the voids on the factory sample. Add 30 mm plates along the edges with holes for attaching to the eyes.
- Make cuts in the middle of each of the matrix compartments and weld eyelets on the back side of the box. This is necessary to allow temporary fastening of void limiters. This way you will have the opportunity, by removing them, to produce monolithic blocks.
- On one of the transverse walls (outside), weld 4 bolts for the mounting holes of the vibration motor.
- Weld the apron and blades along the edges on the loading side.
- Clean and polish all parts for painting.
- Make a press in the shape of the body of the block material - a plate with holes, the diameter of which is 3-5 mm larger than the cylinders. The plate should fit freely to a depth of 50-70 mm into the box where the limiters are installed.
- Weld comfortable handles to the press.
- Paint the entire structure with primer and install the vibration motor.

To convert a conventional electric motor into a vibration motor, you only need to add eccentrics in the form of welded bolts to its shafts. Their axes must coincide. You can screw nuts onto the bolts, selecting the desired vibration amplitude and frequency. You will find more information in our article “Do it yourself vibrating table”.
Such a matrix can become the basis for a stationary or walking machine. To modernize it, you will need developed mechanic skills and more precise execution. There are many machine options and the main factor is the availability of available material (metal).

Material for homemade blocks
Theoretically, “home” blocks can be made from anything - clay, sawdust concrete, expanded clay concrete, etc. The optimal composition of the mixture is 1 part sand, 1 part cement, 3 parts granulated slag.
The decisive point is the moisture content of the mixture, which is easy to determine by eye. The finished mixture should hold the shape of a lump and not crumble. Raw materials of this consistency can be placed in a matrix and pressed into blocks. Instead of voids, you can use glass bottles, broken bricks or sharp-angled stones.

Working with a homemade machine
Before the first load, lubricate all contact surfaces with oil - the solution will stick to the metal less. The vibrator can be turned on at any stage, but it is most effective to do this before pressing. Take care of reliable electrical insulation of the motor. The apron should cover it from the mixture.
Finished blocks should be kept outdoors in summer weather (from +10 to +30 °C) for 3 days. The field with finished products must be covered with polyethylene to avoid early drying.
The simplest form for blocks. Video of the work process
Perhaps such a machine will not become a source of reliable and practically free material for the construction of a residential building, but it will help to significantly save on maintaining a household or constructing a garage. By using masonry mortar (1 part cement, 3 parts sand) to plaster the walls, you will extend the service life of your homemade cinder block by at least 1.5 times.
Making cinder blocks at home is a profitable business idea. By receiving free drawings and a description of the technology from us and with a little effort, you will receive high-quality equipment that guarantees regular income!
High-quality cinder block is a building material that is in demand always and everywhere. Thanks to its large weight and convenient size, it allows you to lay structures of any complexity and height (from an ordinary extension to a house to industrial workshops).
Equipment for the production of cinder blocks at home
The presence of a vibrating machine will make the cinder block more dense and of higher quality, avoiding the formation of unnecessary voids. The vibrating machine will significantly increase the quantity of manufactured products. Now you don't have to wait for the concrete blocks to set completely before moving on to another batch.
Do-it-yourself vibration machine for the production of cinder blocks
The best option at home is a machine with 4 sections at once. In order to make such a machine, which allows you to produce about 100 cinder blocks per hour, you need to first download a 3D model of the machine:
- After taking the measurements, cut out the parts for the future shape from sheet metal about 2 millimeters thick.
- Then the sheets are welded together in such a way as to obtain a shape without a bottom. The height of the mold is 50 millimeters higher than the height of a standard cinder block. This is done so that the solution can be added immediately, rather than adding it over and over again after shrinkage.
- Separately, we cut out pipes equal to the height of the resulting metal mold. They will form the necessary voids. Weld the holes at the ends according to the diameter, making the pipe “blind”. This will make it easier to remove the dried cinder block.
- The cylinders need to be connected to each other closer to the top, maintaining the required factory distance. They must be firmly welded to the lifting lid.
- We securely attach the vibration motor to the outside of the mold. It will ensure correct and rapid shrinkage of the solution. This is how the vibration casting process is carried out.
By looking at the 3D model of a cinder block machine, you can easily figure out how it works and what the principle of its operation is. And the dimensions of the model allow you to easily make the same equipment with your own hands according to the sample.
The kit contains drawings of a machine for the production of cinder blocks with your own hands and diagrams of simpler models of vibrating machines for the production of cinder blocks:
Note. 3D models are saved in file formats: *.sldasm (an extension of the SolidWorks 3D editor, also supports free eDrawings) and *.step (a standard for exchanging 3D graphics that is supported by most 3D editors, including free ones: FreeCAD, Blender, etc.).
Making cinder blocks at home
The cinder block is made in a special form by vibration shrinkage of concrete mixture poured inside. After the material hardens, the hollowness of the block is about 30%-40% (depending on the shape - round or square) of the total area. The resulting cavities not only save consumables during the production of cinder blocks, but also serve as air cushions for sound insulation. They are also excellent for reinforcing masonry, which gives walls maximum stability.
During manufacturing, it should be taken into account that the standard size of one cinder block is 39 x 19 x 18.5 centimeters. This is a standard, a generally accepted value from which builders build when designing and performing calculations. Therefore, strictly follow the parameters during home production of building blocks.
To produce cinder blocks on your own machine you will need:
- cement (M400, but better than M500);
- water;
- coal slag;
- gravel (about 10 millimeters in diameter);
- sand;
- plasticizer (strengthens and dries blocks much faster in 2-3 days);
- mesh seeder for cleaning sand from impurities;
- concrete mixer;
- shovel;
- pallets on which you will dry the building blocks.
Attention! When preparing a concrete mixture, you should always control the amount of water in the composition. If you exceed the water norm by 30%, the concrete product will be exactly 2 times weaker!!!
All components of the solution are taken in the following proportion: 7 parts of slag, 2 parts of sand and gravel, 1.5 parts of cement, 0.2% plasticizer and water. The mixture should be moist and crumbly (fundamentally different from bricklaying mortar). When squeezed tightly in your hand, it should hold together in a lump, and when it falls to the ground, it should crumble. During the vibration of the machine, the mixture is compacted and visually, as if it squeezes out water, turning into a liquid solution. This is a natural vibration casting process for concrete. If the resulting concrete is too liquid, then no vibration rack will help ensure the integrity and strength of the cinder block, which will not dry completely and will soon begin to fall apart.
Financial costs for the production of 1 m 3 (71 pieces) of cinder blocks at minimum cost product:
When producing durable cinder blocks (for load-bearing walls), a semi-dry mixture is prepared for thin-walled concrete products. In the article “production of paving slabs” you can get acquainted in detail with the process of preparing a high-quality and durable concrete mixture of thin-walled products.
Note. It is worth noting that expanded clay concrete blocks are also produced using the same technology. Only the composition and recipe for preparing concrete differs.
Profitability of cinder block production
So, the cost of one square meter of steel sheet will be about $4.3. Buying a motor (you can use a used one to save money) will cost an average of $30. One meter of pipe with a diameter of about 15 mm costs $1.4. If you have no experience in welding metal structures and the necessary equipment, be prepared to pay another $100 to a specialist who has the necessary skills.
This means that a home vibrating machine will cost about $400. At the same time, the cost of materials for the solution, which is enough to make a daily norm of 100 cinder blocks, will be another $30. Be prepared to spend $700 a month on consumables for preparing concrete, etc. As a result, to start your own business you will need $1200-1300.
How quickly will this money be recouped? The cost of one factory-made cinder block averages about $0.7-$0.85. At the same time, home-made products will be sold cheaper, i.e. about $0.5. We will take this amount as the basis for calculating profit.
If you produce 100 pieces of products per day, you can earn about $20. Income per month if there is established sales will be about $600. As you can see, you can not only recoup your investment, but also gain profit in a short time.
As you can see, having your own vibrating machine for vibrating casting building blocks can not only simplify and reduce the cost of your construction, but also give rise to a profitable business!
The production of concrete and expanded clay blocks requires special equipment. Making them yourself allows you to save up to 40-45%. A vibrating machine for producing blocks can be purchased in specialized stores or assembled yourself.
There are several classifications of equipment:
1. By type of control - machines with manual and foot control. The first option is extremely simple to use, but it can only be used for amateur purposes, for example, at the dacha. The second option - an ergonomic vibration machine with foot activation for the production of blocks is a more complex device. It is convenient to launch and is often multifunctional.
They allow you to make wall blocks with different fillers and paving slabs, and contain attachments for cutting or grinding them. Can be used for both amateur and commercial purposes.
2. By the amount of materials received - how many vibrating machines for the production of expanded clay blocks, or their other varieties, can make at a time. Most manual models are designed for 1 product, rare types are designed for 2, professional and semi-professional machines can produce from 1 to 3 at a time. Devices for 2 blocks, according to people experienced in this field, are considered the most optimal option. The medium-power motor built into such machines is just enough to evenly distribute the viscous cement mixture over the mold. As a result, the output is two high-quality and durable products without chips or messes.
3. By type of blocks produced - they are divided not only by the type of filler used, but also by structure and shape. We are talking about solid blocks, with round or rectangular voids, as well as partition blocks. Expensive and sophisticated vibrating machines are multifunctional, allowing you to make even paving slabs. Cheaper models are used to make 1 or 2 types.
General information about the device
To produce building wall blocks, you will need a vibrating machine of any type, consisting of the following parts:
- Molds for production - for 1, 2 or 3 products.
- A vibration mechanism necessary for uniform distribution of the concrete mixture throughout the mold.
- A motor with a starter that drives the vibration mechanism.
- A pressure strip that influences the formation of products.
- A steel frame on which all components are installed.
The technical characteristics of vibrating machines are an important factor that should definitely be taken into account when purchasing them. What exactly do you need to pay attention to? Firstly, the type of device - it can be mechanized or automated. Secondly, the power of the electric drive - 250 W is considered the optimal indicator. Thirdly, you need to pay attention to dimensions and performance. It is also important to take into account the sizes and shapes of the blocks being manufactured and their quantity.
How to make a unit with your own hands?
If you do not have enough money to purchase new equipment, do not rush to buy a used vibrating machine for making blocks. There are many reasons for this, but the main one is that you will not be able to reliably find out exactly how long the device has been in use and in what condition its components are. And they are unlikely to provide you with a guarantee for it. What to do in this situation? Make a vibrating machine with your own hands. To do this, you will need not too expensive materials, most of which are always available from a good owner.
Here are step-by-step instructions for assembling the equipment:
1. Using a grinder, cut a sheet of metal with a thickness of at least 2 mm. This should be done in such a way that you can subsequently weld the box without a bottom to the size of future products.
2. On all lower parts of the mold, cut approximately 1/3 of the way for cushioning. Before welding the form, it is advisable to secure it with clamps and check for symmetry. After the box without a bottom is ready, 2 handles from the profile should be welded to it, so that after shaking the product, it can be placed on a rubber band moistened with any soap solution to obtain blocks with smooth edges.
3. Weld a piece of steel profile to the bottom of the mold, which will hold the cement mixture.
4. Weld a tray for pouring concrete and corners for attaching the vibration unit and motor with starter to the frame.
5. It is necessary to attach holders to the vibrator, which will ensure its continuous contact with the truss filled with cement-sand mortar.
It is important to know that connecting a motor, even with low or medium power, requires some knowledge in the field of electricity. If you are not confident in your abilities, consult a specialist.
Price
