Aiming at the technical problems of low capacity, high energy consumption and narrow application field, the R&D team of Liming Heavy Industry has devoted many years to developing a new generation of pulverizing equipment. The equipment adopts the principle of material layer grinding to grind materials. The energy consumption of the grinding system is 20-30% lower than that of other grinding equipment. Moreover, with the increase of moisture content of raw materials, the power saving effect is more remarkable. It can also be used to produce coal powder or gangue for steel plant, thermal power plant and cement plant. Besides, it can help finish pre grinding for desulphurization in power plant, slag powder and cement clinker. In addition, it can also process steel slag, blast furnace slag, power plant slag and fly ash. Well, this grinding mill can also be used in the glass fiber industry, the production of various chemical raw materials in chemical industry, and the industrial preparation of various materials in more than 100 other industries.
