Alunite grinding mill

الوصف

Alunite is a sulfate mineral, it occurs as veins and replacement masses in trachyte, rhyolite, and similar potassium rich volcanic rocks. It is formed by the action of sulfuric acid bearing solutions on these rocks during the oxidation and leaching of metal sulfide deposits. Alunite also is found near volcanic fumaroles. The white, finely granular masses closely resemble finely granular limestone, dolomite, anhydrite, and magnesite in appearance. The more compact kinds from Hungary are so hard and tough that they have been used for millstones.
Alunite can be used to make alum, potash fertilizer, sulfuric acid, and aluminium.

Performance and features of Clirik Alunite 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 **5 times as long as that of vertical impact crusher and turbo-mill. Especially when handling calcium carbonate and calcite, the lifetime can reach **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 D*7≤5μm.
5. Environment friendly
The application of DMC***0 pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard

Production Line Configuration of Clirik Alunite grinding mill:
The whole set HGM Clirik Alunite grinding 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 Clirik Alunite 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 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.

Detailed Product Description about Clirik Alunite grinding mill:
Clirik Alunite grinding mill is mainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, and talc etc, totally more than **0 kinds of materials. Product fineness can be controlled between **0~***0 mesh (*7~5 micron) .Comparable with ball mill, Clirik Alunite grinding mill has features of low cost, high capacity, easy operation.
