At present, the company sells three kinds of mill products which can be used in gypsum grinding production: European version high efficiency crushing mill, Raymond mill and T130X enhanced ultrafine mill. This paper mainly introduces the application of T130X Series in gypsum grinding production. Ultrafine mill in gypsum grinding production, its production principle is material extrusion grinding. Material enters the grinding chamber from the inlet of the equipment, and then falls between the grinding ring and the grinding roll. The grinding roll squeezes the material onto the grinding ring under the action of centrifugal force, and the effect between the two ultimately makes gypsum grinded. The gypsum material that has not been grinded will fall to the bottom of the grinding chamber, and then be re-thrown by the bottom spade between the grinding roll and the grinding ring for re-extrusion grinding until the fineness of the gypsum powder reaches a certain level and can be blown up by the wind. The wind blows gypsum grinding material through the separator blade, which can be collected to obtain the finished material.
The fineness of gypsum grinding by ultrafine mill ranges from 200 mesh to 400 mesh. The gypsum powder obtained by grinding has many industrial uses, such as building materials, construction industry production, chemical industry production and agricultural production, which can not be separated from the participation of gypsum. Here is an introduction. In the construction and building materials industry, gypsum can be used to produce cement and cementitious materials, glass, plastics, rubber, paint, asphalt, felt, etc. In the chemical industry, gypsum can be used to produce sulfuric acid, ammonium sulfate, etc. In agriculture, gypsum can be used to produce some pharmaceuticals, to improve the acidity and alkalinity of soil, and also to cultivate edible fungi. In addition, gypsum can also be used in the production of feed additives for poultry and livestock raising, and later, gypsum can also be used in cathodic protection production.
