Micro powder grinding mill:, 1) high capacity, 2) low consumption, 3) finished fineness adjstable, Micro powder grinding mill - details see: https://www.machineto.com/hgm-micro-powder-grinding-mill-10169413

HGM micro powder grinding mill ismainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, talc etc, totally more than 100 kinds of materials. Product fineness can be controlled between 325~2500 mesh (47~5 micron)

Comparable with ball mill, HGM micro powder grinding millhas features of low cost, high capacity, easy operation; Comparable with Raymond mill for coarse powder up to 325 mesh, it can produce fine powders between 47 and 5 microns (325 to 2500 mesh)

Performance and features of HGM micro powder grinding 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 shaft 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

Production Line Configuration of micro powder grinding mill

The whole setHGM micro powder grinding millconsists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems

Working Principle of micro powder grinding 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 materials 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
