1. The crushing ratio of grinding machine is very large, simplified crushing process; It is more complex in the concentrator crushing and grinding into a process, make construction grinding machine investment cost greatly reduced;

2. Less grinding phenomenon, be processed mineral surface is clean, the net selected ore quality, and the high quality, as the frame loss less, greatly improve the mineral processing index;

3. The process of grinding machine is dry operation, especially suitable for China's southwest, northwest regional water shortage;

4. The process of grinding machine is simple, high production efficiency, can maximum limit satisfy the production requirements.
