Vacuum Extruder Clay Brick Production Line Capacity Weight 30000kg

Vacuum Extruder

Two-stage vacuum extruder is currently the most common brick-making equipment used in sintered brick factories. The main body of the two-stage vacuum extruder is welded with high-quality steel plates, and has the characteristics of compact structure, high extrusion pressure, high vacuum degree, sturdy and durable, low energy consumption, convenient maintenance, etc.; small investment, is the choice of small and medium-sized brick factories ideal equipment. It is suitable for the production of solid bricks, load-bearing porous bricks and various specifications of high-porosity hollow bricks made of clay, coal gangue, shale, fly ash, urban construction waste, tailings waste, and inferior soil.

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.
