Detailed Product Description about Vertical roller mill:
Vertical grinding mill is mainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs’ hardness under nine. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, and talc etc, totally more than 100 kinds of materials. Product fineness can be controlled between 20~3000 mesh
Comparable with ball mill, Vertical roller mill has features of low cost, high capacity, easy operation.

Production Line Configuration of Vertical stone roller mill:
The whole set HGM Vertical grinding mil consists of  hammer crusher, bucket elevator, storage hopper, vibrating feeder, vertical roller mill, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems

Working Principle of Vertical stone roller mill:
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse powder return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
