Gypsum is usually white, colorless transparent crystal, when impure ingredients can be dimmed, red, yellow or black. Hardness is 1.5-2. Specific gravity is 2.3. With superb flexibility and flexibility, gypsum is a widely used industrial material and building material. Typical applications are found in retarder for cement, gypsum building products, model making, medical food additives, sulfuric acid production, paper fillers and paint fillers.

Gypsum processing system five processes
According to the technical requirements, gypsum production line is usually divided into five parts, which are broken system, material storage and conveying system, grinding system, calcined system, and electric control system.
In the production and processing of gypsum, mainly using the following equipment sets: jaw crusher, bucket elevator, electromagnetic vibrating feeder, grinding mill machine, analysis machine, auxiliary equipment, fans, focus electronic control and other equipment pieces. According to different needs, mill production line can be optionally configured with vertical mill machine, MTW European trapezium mill, high pressure roller mill, Raymond mill, super pressure trapezium mill, three ring medium speed micro powder mill, HGM micro powder mill and so on. Liming Heavy Industry designs dozens of specifications of gypsum production line, according to the different production processes tailored to the needs of different gypsum production lines.
The large-size gypsum ore which is processed by the crusher is broken into small particles less than 30mm and transported to the mill machine for grinding. After grinding to the required fineness, cornflour gypsum products are separated and sent into the fluidized bed furnace for calcination. The rest part returns to mill grinding again until qualified. Calcined qualified gypsum powder is sent into clinker storage or fed into the products workshop.
