In industrial coal pulverizing, gypsum powder processing industry occupies a larger proportion. Gypsum powder is one of the five gel material, occupies an important position in national economy, it is widely used in construction, building materials, industrial molds and art model, chemical industry and agriculture, food processing and medical hairdressing, and many other applications, is a kind of important industrial raw materials.

Gypsum powder production line process can be summarized as: gypsum ore to vibrating feeder, jaw crusher - bucket elevator - raw materials warehouse to mill, bucket elevator to fluidized bed to bucket elevator, conveyor, cooked bin cooling, storage and finished products. The vertical roller mill is particularly critical.

Shanghai Clirik Machinery Company is in the use of vertical roller mill products at home and abroad advanced structure, and on the basis of the micro powder grinding industry update design improvements, especially suitable for the gypsum powder processing production. The equipment than ordinary mill with high efficiency, low power consumption, cover an area of an area small, one-time investment is small. Roller under the action of centrifugal force, rolling on the grinding ring tightly, so when the grinding roller and grinding ring wear to a certain thickness does not affect the output of finished products and fineness. Grinding roller and grinding ring replacement cycle is long, so as to eliminate the disadvantage of the centrifugal mill parts replacement cycle is short. It is the winnowing of airflow in the fan - mill shell - circulation flow in cyclone separator, fan operation, so less than high-speed centrifugal mill dust, workshop clean and environment friendly operation. Clirik vertical roller mill is welcomed in the micro powder mill market.
