What are dry and wet grinding? Dry grinding. Dry grinding means that after the ore has undergone a certain crushing operation in the ball mill, it will be taken out by the airflow drawn out of the barrel when it meets the requirements. The ball mill used in the dry grinding process is a dry ball mill. The dry ball mill does not need to add ...
