vacuum extruder china
The red brick machine, also known as the vacuum extruder, adopts the principle of single machine extrusion, uses an electric motor, and drives the upper mixing and lower extrusion parts synchronously through an axial pneumatic clutch and a reducer. The entire machine is made of all steel structure, and the body is welded from steel plates. It is a single axis, single mud cylinder, and single spiral coaxial sealing mechanism. All reducers are hard toothed gears. The cutter adopts wear-resistant material spray welding technology, which is easy to maintain and sturdy and durable. Suitable for producing hollow bricks from shale, coal gangue, high content fly ash, and poor plasticity raw materials.
Brick machines are divided into two categories: vacuum brick machines and non fired brick machines. The former is made from soil and requires a large amount of soil to make bricks, which is a waste of resources. The latter is made from waste coal gangue, shale, stone powder, fly ash, slag, slag, crushed stone, sand, etc., without going through the firing process, which is more environmentally friendly and resource saving, and has been vigorously promoted by the country.
The bricks produced by vacuum brick machines are mainly made of clay as the main raw material, and their production process is simple, but it causes serious damage to farmland. In 2015, the country successively introduced policies to prohibit the production and use of clay bricks, and vigorously promoted the reuse of solid waste. And brick products using fly ash as the main production raw material and gypsum and quicklime as the main bonding materials are gradually replacing traditional clay bricks.
Vacuum brick machine produces brick billets
Mix the clay with a clay mixer, add some sand and stone powder, mix well, and then transport it through a conveyor belt to a vacuum brick machine. After being compressed by vacuum pressure in the vacuum brick machine, the brick is formed. After the brick is produced, it is divided into evenly sized bricks by a dividing machine. Then, it is automatically grabbed by a coding machine, placed in a kiln car, and fired in the furnace.
