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.

Performance and features of Vertical stone roller mill:
1. High efficiency
Under the same final size and power, the product capacity of micro powder grinding mill is twice than jet mill and agitation mill.
2. Long lifetime of wearing parts
The roller and ring are made of special material, which improve the grinding efficiency a lot. For same material and final size, the lifetime of its wearing parts can reach to more than one year, about 2-5 times as long as that of vertical impact crusher and turbo-mill. Especially when handling calcium carbonate and calcite, the lifetime can reach 2-5 years.
3. High safety and reliability
There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding or wear of bearings and seal components will never happen.
4. High fineness of products
The product fineness can reach D97≤5μm.
5. Environment friendly
The application of DMC-120 pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard
