Intermittent ball mill is applied to the grinding of feldspar, quartz, clay, silica and other hard and brittle materials, it is widely used in industrial production of high fine grinding materials. one. There are both wet grinding and dry grinding, especially the dry grinding can produce ultra-fine powder and the fineness could upto 1000-16000 meshes. the adapting of special inside lining reduce the admixture of steel, iron, manganese and other metal materials to the component. This machine is high fine grinding machine, material should be crushing in fineness state into the ground to have the highest grinding efficiency and economic benefit.
