Calcium Carbonate powder mill;powder mill equipment

Introduce Of Calcium Carbonate powder mill;powder mill equipment:

non-inflammable, non-explosive and brittle materials with mohs' hardness under six, such as calcite, kaolins, limestones, calcite, barites, carbon black, mica, quartz etc. With the development of high-tech industry, fine and superfine powder is widely applied in various fields, so Clirik Calcium Carbonate powder mill;powder mill equipment become more and more requires by various industries.

Working principle of Calcium Carbonate powder mill:

ClirikCalcium Carbonate powder mill;powder mill equipment mainly consists of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
 

After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, edge of then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe. When the Calcium Carbonate powder mill;powder mill equipment is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers. The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the air flow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall an exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end.

1. High efficiency

Under the same final size and power, the product capacity of  Calcium Carbonate powder mill;powder mill equipment 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≤5μm.

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.
