Spiral conveyor of shale brick making machine adopts wear-resistant metal powder spraying technology; Spiral conveyor adopts wear-resistant metal powder spraying technology; The upper stage mixing shaft, spiral conveyor shaft and machine body are processed by aging, tempering and quenching; the gear of reductor are hard-toothed surface; clutch adopts screw compression type patent technology, it greatly improves machine working life. 

FengYuan Machinery Manufacturing Co., Ltd. is specializing in vacuum brick making machine over 10 years, our machines have advanced function and completed product specification. We developed double-stage vacuum extruding machine, which produces all kinds of solid and hollow brick with coal gangue, shale, fly ash and clay etc. It's also called as shale brick making machine, coal gangue brick making machine, fly ash brick making machine etc. Complying with different raw materials.

The trowel of double-stage vacuum brick making machine adopts wear-resistant metal powder spraying technology; The upper stage mixing shaft, trowel and machine body are processed by aging, tempering and quenching; the gear of reductor are hard-toothed surface; clutch adopts screw compression type patent technology, it greatly improves machine working life. The reasonable design and compact structure maks machine running smoothly without installing anchor bolt, and greatly reduce the consumption of power which caused by shocking of machine during equipment running.
