① on the physical properties of materials (such as particle size, moisture content, hardness, etc) fluctuation of adaptability and its productive capacity is large.
II crushing ratio (generally more than 300 ultra fine grinding up to 1000 or more), the fineness of the product fine, and grain grading is easy to adjust.
③ jobs can be adapted to different circumstances: the operation can be dry or wet operation, drying and grinding can be taken together, the two processes at the same time operations; open circuit grinding or close-circuit grinding.
④ sealing good, operation under negative pressure and dust in the workplace.
⑥ for large, to meet the needs of mass production of modern enterprise.
