What Are the Differences between Dry and Wet Type Ball Mill?

Dry grinding means that when the ore is ground into required particle size, the powder will be brought out from the dry ball mill by airflow. Dry grinding process: 1 The material from the feeding device is evenly fed into the first bin of ball mill by the hollow shaft spiral. This bin has stepped lining or corrugated lining, which is filled ...
