In recent years, the domestic non-metallic mineral powder grinding processing industry develops rapidly, especially for the techniques of micro powder and superfine powder. In addition, the industrial mills have wider and wider applications such as the development and utilization of silica powder and coal ash. At the same time, the importance of industrial mills is more obvious with their applications in industries like cosmetics, painting and plastic.Powder grinding belongs to high energy consumption industry. In order to grind raw materials to fine powder and superfine powder, the power consumption is usually higher than 300kw.h/t. In order to realize the high efficiency and low energy consumption in the process of powder grinding mini crusher plant, Zenith experts designed different types of grinding mills such as micro powder mill, high pressure grinding mill, etc. However, no matter which kind of working method these equipments adopt, they all improve the working efficiency by increasing the grinding strength. And they have relatively high requirements on the raw materials and impurities are not allowed.Micro powder small scale gold washing plant mill is a kind of new type grinding mill which grind raw materials into fine powder under the force of high pressure blower by the grinding force of grinding rollers and grinding rings. In the whole operating process gold mining stone crushing south africa of the grinding mill, alluvial gold mining machine for sale the grinding cavity is a low pressure sealing system equipped with dust collector so as to guarantee the high efficiency and stable operation of the whole grinding mill system. In addition, this type grinding mill can meet the national standard on the environmental protection. In the superfine powder field, this new type micro powder mill can easily realize the fineness range from 600 mesh to 2000 mesh. Moreover, no matter in the technical innovation or investment cost, this grinding mill can be the preferred equipment.Grinding equipments have gained great achievements in the past ten years and they are developing towards the direction of large scale gradually. In addition, the application fields becomes wider and wider with higher efficiency, lower energy consumption and less pollution. In the meantime, large high efficiency vertical mill also gives full play to its excellent performance in the coal grinding and coal ash processing industry which used to be difficult to conquer.
