The purpose of gypsum powder is mainly used in building materials and the pharmaceutical industry, also differ due to different purposes of its processing technology, mainly lies in its fineness, purity and analyze two different purposes under the gypsum powder processing technology Because the gypsum powder production technology without crusher, mill processing, above are the two process.
Building materials application: made from powder to calcine, because building materials requirements is not high, we choose cheaper calcination scheme of using coal as raw materials, is burning with the dryer. After calcination for cooling, then the conveyor directly into the finished product storage warehouse.
Medical purposes: because of the demand is higher, and can't pollution, using natural gas as the fuel of rotary kiln for calcining, and then by the cooling machine cooling.
In China the most widely used desulfurization gypsum, phosphogypsum and natural gypsum production building gesso project process is divided into four steps:(1) crushing (2) pre grinding (3) calcining (4) the loading transportation
The manufacturing method is mainly used in the industrial by-product gypsum production building gypsum powder, with minimal investment of equipment, the lowest coal consumption, power consumption, in the production of high-grade gypsum powder and a variety of products.
As the earth's crust, shaped like a rock mineral gypsum layer, in the process of the gypsum slurry is not complicated, and gypsum powder production process is simple and flexible, meet the needs of building indoor construction. In building materials industry, with the increasing of high-rise building and national wall change work progressed, gesso building materials market has become a tight product. As a necessary equipment of gypsum powder production process, the use of the crusher, mill also more broadly, the market is an increasing demand for crusher, mill.
