There are several steps to traditional brick making

The main steps of brick making are:

1.Take the soil. The soil used to burn the bricks is taken from ancient soil, which is two feet deep below the surface, and the color of this soil is slightly darker than that of the surface soil, and it was formed about 80,000 to 120,000 years ago.

At that time, the earth's climate was warm and humid, and the rich biological processes made the soil formed during this period soft and sticky, making it an excellent material for firing bricks and tiles.

2.The excavated clay is exposed to sunlight, snow and rain to decompose and loosen the clay after about half a year of open-air accumulation, and then crushed and sieved by hand, leaving only fine pure soil.

3.The pure soil is moistened with water, and then repeatedly refined, or the ox force is trampled to make it into thick mud, and it takes about 5 to 6 times to turn the mud and refine it manually, which plays a vital role in the quality of the final brick.

4.The soil is turned into a wooden billet mold, compacted, and scraped off the excess mud with a wire bow to form a blank shape. Before making the billet, a layer of fine sand is sprinkled on the ground under the wooden mold to prevent the mud from sticking to the ground.

5.After demoulding, the bricks should be placed in the shade to dry in the shade to prevent cracks and deformation caused by sun exposure.

6.After the bricks are completely dried (about one to two months), they are fired in the kiln, which is the most important part of the whole brick-making process.

7.After more than ten days of firing, the green body has basically been sintered, such as slowly extinguishing the fire at this time, the outside air enters the kiln, and the green body appears red after cooling, which is our common red brick, green brick.

It is necessary to turn rust in the kiln, the method is to seal the vent hole on the top of the kiln with soil when sintering the bricks at high temperature, reduce the air ingress, and make the temperature in the kiln turn into the reducing atmosphere, so that the red high-order iron oxide of the green body is reduced to the blue-gray low-valent iron oxide, in order to prevent the low-valent iron in the green body from being re-oxidized, the iron drinking water is on the top of the kiln sealed with soil, so that the water becomes vapor when it encounters high temperature, and absorbs the heat in the kiln, and the green body in the kiln continues to maintain the reducing atmosphere in this cooling process until it is completely cooled out of the kiln. The process of turning from loess into green bricks is complete.

The traditional brick-making process is as follows:

First, prepare the raw materials for production. Nowadays, more and more buildings no longer use clay bricks, especially high-rise buildings, and more autoclaved aerated concrete blocks are used. This new type of building material is not only several times the performance of clay bricks, more importantly, cheap, aerated concrete blocks are better to use and cheaper than clay bricks, mainly because aerated concrete blocks are based on fly ash as the core raw material, after ball milling and grinding, mixed with a small amount of cement, gypsum and foaming agent.

Second, after the material is prepared, it is added to the pouring mixer, and then the aluminum powder suspension is added and stirred into a slurry. Thirdly, after stirring evenly, the production materials are mixed. Fourth, the molding stage.

Through the screw conveyor, the mixed slurry is poured into the mold basket. Fifth, after **, then push the room temperature to 50 70 in the initial room for initial condensation, after an hour and a half, it can be coagulated into a lump, and then sent out of the primary room. Sixth, molding.

Then it's time for the polishing and cutting of the grain. First, use a negative pressure spreader to lift the mold basket and the embryo body to the cutting table together, and then the worker removes the baffle plate, makes the box rotate 90 degrees, and takes out the mold basket. Seventh, after taking out the mold basket, cut out the rough texture and shape according to the requirements.

Eighth, curing autoclaving, put the cut embryo body on the pre-prepared axe bottom plate, push it into the axe car together, and send it into the autoclaved axe in a group of three to cover the axe door, and then you can carry out maintenance autoclaving. Ninth, after the autoclaving is completed, it is time for the packaging stage of the product, and it can be shipped out of the warehouse after the packaging is completed. In this way, the concrete block is made.

There are several steps in the traditional brick-making, first of all, after digging up, call the water and oil, or use people to pick your full color Nuonuo, and then use the wood incense to make a dozen into a ball, packed in it, so that the traditional bricks and clay embryo bricks are made, and then dried and then fired in the kiln.

The first step is your choice of yellow mud, there are no stones, all are yellow mud dredging to make bricks, the bricks have to be dried in the sun, and the bricks can be burned only after drying.

Bricks are made of clay (including shale, gangue.

and other powders) as the main raw materials for firing. Brick is the most traditional masonry material. From clay as the main raw material to the use of coal gangue and fly ash and other industrial wastes, at the same time, from solid to porous and hollow, from sintered to non-sintered.

Steps of burning bricks: 1. Take soil. The soil used for burning bricks, commonly known as clay, is said to have been formed about 80,000 to 120,000 years ago, when the earth's climate was warm and humid, and the rich biological processes made the soil formed during this period soft and sticky.

2. The excavated clay will be exposed to wind and sun for up to half a year, and then naturally eroded and decomposed and loosened internally, and then crushed and sieved by hand, leaving only fine pure soil.

3. Add water to moisten the pure soil, repeat and refine like the noodles, of course, here is certainly not by hand, you can use ox force to trample on it, make thick mud, manpower mud turning and refining about 5 to 6 times, this process plays a vital role in the quality of bricks.

4. The smelted clay is molded through the billet molding, the clay should be compacted when shaping, and the place where the bricks are placed should be covered with fine sand to prevent you from sticking. The bricks should be dried in the shade, and should not be exposed to the sun to cause cracks and deformations in the bricks.

5. After the bricks are completely dry (about one to two months), they can be fired in the kiln, which is the most important part, the general bricks use coal as fuel, and the filter mortar bricks with higher density are slowly burned with wheat straw, pine branches and other fuels.

6. After more than ten days of firing, the green body is sintered. If the fire is slowly turned off at this time, the outside air enters the kiln, and what comes out is our common red brick. If you want green bricks.

When the bricks need to be sintered at high temperature, the vent hole on the top of the kiln needs to be sealed to reduce the air ingress, so that the temperature in the kiln is conducive to the reduction of the brick composition, and the red high-grade iron oxide of the green body is reduced to the blue-gray low-valent iron oxide, in order to prevent the low-valent iron in the body from being re-oxidized, the iron drinking water on the top of the kiln sealed with soil has achieved the purpose of cooling until it is completely cooled out of the kiln.

Brick banquet round noisy is a kind of rectangular stone used for building walls, made of clay firing, mostly red, commonly known as "red bricks", there are also cyan "green bricks". The size of the Chinese standard clay brick is 240 115 53mm, and the purpose of this size is to ensure that the ratio of length, width and height of the brick is 4 to 2 to 1.

Bricks: According to the different parts used in construction projects, bricks are divided into wall bricks, floor bricks, arch shell bricks, floor bricks, sewer bricks and chimney bricks. According to different architectural cavity bending energy, wall bricks are divided into load-bearing bricks, non-load-bearing bricks, engineering bricks, thermal insulation bricks, sound-absorbing bricks, facing bricks, flower plate bricks, etc.

According to the characteristics of the production process, bricks are divided into two categories: sintered products and non-sintered products. According to the different raw materials used, bricks are divided into clay bricks, shale bricks, coal annihilation stone bricks, fly ash bricks, slag bricks, lime sand bricks, etc. According to the shape, bricks can be divided into solid bricks, microporous bricks, perforated bricks and hollow bricks.

Ordinary bricks and special-shaped bricks, etc.
