double stage vacuum extruder is the best choice to produce the hollow clay bricks. With the advantages of Strong Extrusion Pressure, Vacuum Extruder ,Replaceable Mold , extracting the air form the raw material so that can guarantee the compactness of the raw materials. therefore, the quality of the hollow bricks are very good.
Features:
1. The spiral cut reamer of the machine adopt wear-resistance metal spray painting technology;
2. The upper stage mixing shaft, the cut reamer big shaft, the up-down body etc. are all passed the aging, quenching and tempering process.
3. The reducer gearwheel is the hardened tooth face. Adopting the spiral pressure plate patent technology on the clutch largely prolonged the service life of equipment.
4. At the same time, reasonable design, compact structure , the equipment can work steadily without installing of foundation bolts. It can largely reduce the consumption of vibration in working process.
