Bentonite clay mill machine, mineral mill

There are different types of bentonite, each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al). Much of bentonite's usefulness in the drilling and geotechnical engineering industry comes from its unique rheological properties. Bentonite can be used in cement, adhesives, ceramic bodies, and cat litter. Bentonite is also used as a binding agent in the manufacture of taconite pellets as used in the steelmaking industry. Bentonite can also be used as a desiccant due to its adsorption properties.
>> Introduce Of Bentonite clay mill machine, mineral mill
HGM series Bentonite clay mill machine, mineral mill is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs’ hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, etc, totally more than 100 kinds of materials. Product fineness can be controlled between 325~2500 meshes.
Production Line Configuration of Bentonite clay mill machine, mineral mill:
>> The whole set HGM series Bentonite clay mill machine, mineral mill consists 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 Bentonite clay mill machine, mineral 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.
>> Performance and features Of Bentonite clay mill machine, mineral mill:
1. Under the same final size and power, the product capacity of Bentonite clay mill machine, mineral mill is twice than jet mill and agitation mill.
2. 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 Bentonite and calcite, the lifetime can reach 2-5 years.
3. 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. The product fineness can reach D97=<5um.
5. The application of pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard
