According to the hardness and fineness of material, and the final output, grinding mill can be divided into six categories, superfine powder mill, micro powder mill, ultrafine mill, high pressure micro-powder grinder, vertical roller mill, and three-ring middle speed grinding mill. Clirik technologies have many years mill experience, equipment constantly updated, technologies improve, newly developed out of vertical mill, European style mill with energy saving effect, specially meet the world energy reduction advocate. They especially played a key role in the field of flue gas desulfurization in power plant in recent years. Clirik superfine powder mill, micro powder mill, ultrafine mill, high pressure micro-powder grinder, vertical roller mill, and three-ring middle speed grinding mill can process quicklime (oxidation calcium), slaked lime (hydrogen oxidation calcium), kaolin, carbon black,  gypsum, talc, lime, long stone, char, shell red mud, shells, miscellaneous bone, natural rubber, Huang Hongdan, barium sulfate oxidation zinc, iron oxide, calcium carbonate, magnesium sulfate, heavy calcium, graphite, titanium dioxide powder, in the Ridge stone, aluminum ore, coal gangue, diatomite, expansion run stone, maifan stone, Red gravel, ice Chau stone, II oxidation manganese mine, pyrophyllite, calcite, dolomite, Silicon ash stone, Ha Pak Nai clay, titanium iron ore, lapis lazuli, glass, Hu Jing , and Fish meal, etc. hundreds of Mohs hardness below 7 level minerals. Apply to chemical industry, metallurgy, building materials, pharmaceuticals, food, decorations, and other industries.

Clirik ultrafine grinding mill has a certain degree fineness powder of Industrial dedusting and desulfurization, so that Harmful gases and this kind of desulfurization powder mixed, thus harmful gas of sulfur dioxide in the flue gas into the industrial by-product calcium sulfide can be used. This method educed greenhouse gas emissions. Clirik ultrafine grinding mill obtained national invention patent and national utility model patents, equipments have been exported to many countries and regions.
