Alunite and industrial powder grinder in China:
Alunite is a kind of widely distribution of sulfate minerals, alunite can also be used to manufacture potash fertilizer, acid, also can be used to aluminum smelting. Alunite is commonly block or earthy, its crystal is not obvious, it is implicit crystal mineral. If pure should be white, but after containing impurities were shallow ash, pale red, yellow or reddish brown, vitreous burnish, basal cleavage medium. It is industrial extraction alum and aluminium sulphate raw materials, also used for aluminum smelting and manufacturing potash fertilizer, acid. China zhejiang cangnan, anhui LuJiang and fujian zhou ning of cretaceous volcanic rocks have a large number of output, among them, the zhejiang proved reserves accounts for over 50% in China, especially in wenzhou cangnan alum mountain , reserves of 167 million tons. It contains pure alunite 45.4% ~ 47.71%. It is proved the world's largest alunite quarries. CLIRIK provide industrial powder grinder to processing alunite.
CLIRIK industrial powder grinder is for super-fine grinding materials with hardness less than 6 in Moh‘s scale and humidity less than 6 percent such as kaolin, limestone, basalt, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, carbon black, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment, up to 200 kinds. The granularity (or final size) of the finished products can be freely adjusted between 325-3000meshes (0.045-0.0057mm), and the capacity (ton/hour) ranges from 0.4T/H to 12T/H depending on the final size and the grinding materials.
Production Line Configuration of Alunite industrial powder grinder:
1). Hammer crusher, bucket elevator, storage hopper, vibrating feeder,
2). Main unit, inverter classifier, cyclone collector, pulse deduster system,
3). High pressure positive blower, air compressors and electrical control systems.

Features and advantages of Alunite industrial powder grinder:
l、 High efficiency
Under the same finished final size and the same motor power, the capacity of Alunite industrial powder grinder is twice as much as jet mill, mixing grinder and ball mill.
2、Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
3、High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
4、 High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≦5um.
5、Environment-friendly
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
