History of the Development of Industrial Milling Mill According to the Actual Needs Change

  The main industrial milling material is metal and non-metallic mineralization and other organic matter , a common zinc oxide , molybdenum powder, magnesium and other metal mineralization ultra-fine powder , as well as limestone powder, calcite powder, barite powder, calcium carbonate , kaolin powder, talcum powder , fluorite powder, gypsum powder , bentonite powder and superfine powder of non-metallic mineralization . There are two general industrial milling of physical and chemical methods , chemical methods using a variety of chemicals, obtained at high temperature, quenched condition . Physical methods is widely used , a method is more economical , the main principle is the use of different milling machine comprising supporting a classifier , a collector , etc., the processing is made by the physical grinding action .

   From the history of the development of the first industrial mill for the Raymond mill , the first job for powder media , so that now the market is accustomed to industrial milling machines referred to as Raymond mill, Raymond Raymond machines, mine mill . Raymond mill is starting in the structure of industrial roller mill after years of continuous improvement , has achieved a second replacement , from the high -speed milling machine to ultrafine mill , so that overpressure milling machines, milling machines and other European version , are on the basis of Raymond mill , constantly abandoned defects and deficiencies inherent in equipment , research and development from the actual demand constant progress. It is also continuous improvement in order to make the material had only 200 general purpose grinding Raymond mill , now has achieved a Mohs hardness of 9.5 on the following materials to achieve 80-2500 mesh fineness...
