Angle of nip does not explain the findings. In wet-batch ball milling with ore charges from 200 to 35 pounds (about 75 pounds of ore was required to fill the interstices of the balls at rest) and speeds from 30 to 80 percent critical, the slow speed gave the same type of grinding as high speed.
The wet ball mill needs to add liquid medium during the grinding process, and care must be taken to control the grinding concentration properly. The amount of water added is generally determined by the use of the mud, the amount of clay in the formulation, and the water absorption value of the clay.
Dry grinding of the ball mill requires that the material in the mill is dry, and no water or other liquids can be added. The material is ground by the medium of the ball mill in the mill, and the products that meet the requirements are carried out by the wind or airflow. The main equipment of the wet grinding of the ball mill is a wet ball mill.
