Stone powder making unit brief introduction
Stone powder making unit -- the latest grinding equipment, with its own knowledge patents, have reached modern advanced level in the world. This series Stone powder making unit mill absorbing the European advanced technology and many engineers' ripe experience, combining the actual requirement and proposal of our 9518 customers', have been developed on the basis of our professional engineers' hard researching. This new type Stone powder making unit mill adopts bevel gear overall drive, inner automatic Thin-Oil lubricating system, arc air channel and several latest patent technology.
Working Principle of Stone powder making unit
First, raw material should be crushed by the jaw crusher to the size specified, and then the crushed stone is elevated into a hopper from which the stone is loaded, through the vibrating feeder, evenly and continuously into the grinding chamber for power-processing. After this, the ground powder is carried by the air into the separator for screening. The fine powder are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set's airflow system is closely sealed up and circulated under condition of negative pressure.
Special features of Stone powder making unit
1. High efficiency, 0.5-80 t/h
2. Long lifecycle of spare parts. The ring and roller are forged by special material with high utilization.
3. High safety and reliability. As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
4. High fineness and flexible adjustment. 325-2500 meshes
5. Environment-friendly. The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.
6. Advanced intelligent speed control device. Convenient adjusting, more uniform particle size.
