Vacuum Extruder Clay Brick functional machine in brick production line

This machine is suitable for continuous extrusion of wet clay, and it is the key function equipment for forming section of brick production line.

The mud strip extruded by this equipment has smooth and compact surface, good quality, large extrusion quantity, convenient operation, stable operation and good reliability.

This machine can produce solid brick, hollow brick, porous brick, hollow brick and other kinds of bricks.

The machine is composed of upper mixing part, vacuum part and lower extrusion part.

The body of the extruder is welded with high quality steel plate. After aging treatment, the residual stress inside the parts is eliminated, and the hardness and strength are improved. Extruder structure design is reasonable, the body is firm, stable, reliable, durable. Low energy consumption, high production efficiency, convenient maintenance.

The extruder can be equipped with a digital automatic monitoring system, which provides a strong guarantee of continuous and stable operation of the machine.

Key Parts

Spiral blade/reamer

Standard carbon steel material, easy-wear surface of reamer use gas welding and wired with cored wire, the surface of welded workpiece shape smoothly, resistance is small, wear resistance is high, hardness in 52HRC-56HRC, service life is more than the ordinary reamer 4-7 times. The lead (screw lead) is arranged scientifically, with the characteristic of "micro pressure conveying, high pressure extrusion", which can increase the extrusion pressure and improve the working efficiency. Repair can be repeated during use to reduce the cost and increase the utilization rate.

Extruding shaft

The shaft of extruding part adopts floating shaft structure and has the function of automatic centering, so that the shaft only produces torque and does not produce radial force, which can protect the reducer/shaft, and can eliminate or reduce the shake of equipment caused bending shaft after long time use, to make the equipment energy saving 15-30%. The hardness of the shaft is greater than HB220 after thermal refining.

Mixing tooth

High molding casting, hardness in 55hrc-60hrc, life is 6 times of the ordinary mixing tooth.

Mixing shaft

The upper reducer is connected with the shaft by a toothed coupling, which eliminates the coaxiality between the shaft and the reduce.
