Business idea: the production of bricks. Technology and installation for the production of bricks

Brick today is one of the best and most common building materials. It is used by private builders and professional companies. There are small and large enterprises that manufacture and sell these products. You too can create your own business that will meet your requirements, and will also become a source of income. However, in order to obtain high-quality bricks, it is necessary to comply with specifications and adhere to the manufacturing process. The production of bricks at home does not involve the use of expensive equipment. The most important condition is the proper preparation of raw materials.

Production features

Forms can become boards, which are previously knocked together. In the future, they contain raw materials. It is necessary to make shapes of such dimensions that the finished product conforms to the dimensions and appearance of the traditional brick, which has dimensions in the range of 25x12x6.5 cm. The lid will allow the ramming of the raw material, which fits into the molds. The production of bricks will be faster if several templates are made.

Technology of work

The inner side of the mold should be wetted or sprinkled with dry cement in advance. Then the prepared solution is laid. As the form is filled, it is necessary to compact the mixture so that all corners and voids are filled. Remove excess solution with a spatula. Next comes the turn of the lid, which is laid on top. At the next stage, waiting for a certain time, after the expiration of which you need to turn the form and take out the resulting semi-finished product. The room should be equipped with racks under a canopy, on which it is necessary to lay bricks for drying. Natural shrinkage will occur within 15%. At this stage, water evaporates. This becomes a catalyst for the convergence of substances in the mixture.

In this case, the exposure to direct sunlight should be avoided. The production of bricks is carried out in a room that is well ventilated. Drying lasts from 7 to 14 days. It should be remembered that the manufacture of bricks without firing is one of the fastest and easiest methods of obtaining the described building material. As the only but important drawback, it is considered that the resulting products can only be used to form partitions inside the premises. This is due to the fact that moisture can have a destructive effect on them.

Field of use of raw materials

Use the raw material will be possible with the arrangement of partitions and walls, which will be located inside buildings. It can be buildings, as well as baths, which are used for economic purposes. However, in this case, it will be necessary to perform waterproofing from the inside. This material can also be used in the construction of capital walls in buildings that have one floor. In this case, the roof should be wooden.

Carrying out baking

The production of bricks at home involves the next stage of firing. This will get high-quality building material. In the conditions of industrial enterprises, special furnaces are used for this. While in self-manufacturing, you can build a product that is made from available materials. To do this, in the ground, prepare a depression of up to 0.5 meters. Above him, with a deviation from the bottom of 20 cm should be installed a metal barrel, which is devoid of the bottom. In the walls of the tank, it is necessary to make holes in which the reinforcement is installed. On the received shelf it is necessary to lay semi-finished products which have passed preliminary drying. On top of the barrel is covered with a metal cloth. In the prepared deepening it is necessary to build a fire.

Nuances of firing

The technology of bricks production presupposes observance of a certain temperature regime, so that the finished product will turn out to be of high quality. During the first eight hours, keep the temperature within 200 degrees. The firing process takes 12 to 16 hours, during which the temperature should be kept between 800 and 1000 degrees. The next 4 hours the temperature regime should be gentle, from 500 to 600 degrees. Gradual correction of temperature will allow obtaining the desired result, eliminating the occurrence of cracks. You can build a fire with the help of coal or firewood. The filled container must be cooled with a well closed lid. Only after that it will be possible to release the brick, checking its readiness.

Making a lot of bricks

The installation for the production of bricks, or more precisely for baking, can be designed for a more impressive amount of building materials. For this purpose, a stove is being equipped with a container. Its shape should resemble a design narrowed to the top. It is laid raw, covered with sand or soil to provide thermal insulation. After the inside, a fire is built, and the temperature regime should remain the same as the one described above. The production of hyper-pressed bricks is also possible at home. To do this, you will need to use a special machine that compresses the prepared mixture into a more dense mass. For work there will be no need to use electricity. Then the process will be simple enough.

Alternative brick options

The production of clinker bricks involves the use of somewhat more sophisticated equipment. Formation of products is based on the technology of semi-dry pressing. At the same time, there is an opportunity to save electricity. In production, a vacuum press is used, which is sometimes replaced by a lever press. In some cases, the wizard uses a tape installation. After the formation of the billet, the brick enters the drying stage. For this, special electric fireplaces are used, which maintain a high temperature. The most important raw ingredient is refractory clay. It is characterized by ductility and a high temperature threshold. When preparing the solution, metal oxides or minerals are added to the ingredients, which belong to the group of kaolins. This allows you to get stronger products.

Making of ceramic bricks

The production of ceramic bricks at home involves the preparation of raw materials, its formation, as well as subsequent firing. Clay, mined in a quarry, does not fit in its original form for the formation of quality bricks. The mass is brought to the ready, during which the processing activities are carried out. This can be a natural or mechanical effect. At the drying stage, the percentage of moisture content in products decreases to 6%. This indicator is needed to ensure that fires do not form during firing, and also finished products are not deformed. If chamber dryers are used, they will be able to provide a temperature in the range of 120 to 150 degrees. Depending on the humidity of the raw material, as a rule, this stage takes no more than 3 days. The final stage is burning. For its implementation, ring or tunnel furnaces will be needed.

Manufacture of sand lime bricks

The production of silica brick involves the use of autoclave synthesis. In order to produce one unit of material, 9 parts of quartz sand, which is pre-screened, additives, and also one part of air lime will be needed. The last component must be special.
