Gravel grinding mill equipment

Gravel has numbers of source and names. Nature gravel is Large called conglomerate, they are a common geological feature, being formed as a result of the weathering and erosion of rocks. While natural gravel deposits are insufficient for human purposes, gravel is often produced by quarrying and crushing hard-wearing rocks, such as sandstone, limestone, dolomite or basalt.

Our gravel grinding equipments include Raymond mill, HGM ultrafine grinding equipment(HGM80/ HGM90/ HGM100/ HGM100/HGM125). Raymond mill is the vertical grinding mill, which is popular in many countries and has very long history. HGM ultrafine grinding mill equipment is special for super thin grinding. You can choose suitable gravel grinding mill depends on your gravel size, hardness, capacity and your cost budget.

Gravel ultrafine grinding line:

  Clirik has the best gravel ultrafine grinding equipments. Under the same finished final size and the same motor power, the capacity of micro powder grinding mill is twice as much as jet mill, mixing grinder and ball mill. And the application of pulse deduster and muffler greatly alleviates dust pollution and noise. If you want to reduce the cost of production you can choose our gravel ultrafine grinding mill.

>>The Application of gravel grinding mill equipment:

HGM series gravel grinding mill equipment is mainly applied to non-inflammable, non-explosive and brittle materials with Moh’s hardness under six. Such as calcite, chalk, gravel, dolomite, kaolin, gypsum, etc, totally more than 100 kinds of materials. Product fineness can be controlled between 325~2500 mesh.

>>Working Principle of gravel grinding mill equipment:

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 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.

>>Performance and features of gravel grinding mill equipment:

1. High efficiency

Under the same final size and power, the product capacity of ultrafine mill is twice than jet mill and agitation mill.

2. Longer lifetime of spare 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=<5um.

5. Environment friendly

The application of pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard.
