Working Principle of Wet Ball Mill

Wet ball mill includes grid wet ball mill and overflow ball mill, and the feeding materials are ore or slurry that is high water content. The working principle of ball mill is raw material is transported into the cylinder by a hollow journal. With certain speed rotation of the cylinder, the grinding medium-different specification of steel balls rotates. The stress includes gravity, centrifugal force, and frictional force. When steel balls rise to a certain height, and the gravity is bigger than centrifugal force, steel balls would fall down and are divorced from the cylinder. Since the gravitational potential energy is transformed into kinetic energy, steel balls collide with ore at certain final speed and crush the ore by impacts. At the same time, during the process of steel balls???rotation, there is also a grinding effect because of the sliding and dislocation motion among steel balls. Due to the continuously feeding materials, the pressure pushes materials to the outlet and the ground materials are discharged from the cylinder outlet. Qualified materials flow from the cylinder outlet.

In the ball mill, the height of grinding medium and its trajectories are related to cylinder’s speed, the quantity of medium and the type of liner. Normally, the motion state of a medium can be classified into three kinds according to the speed of cylinder, which is increasing from low to high: draining downstate, throwing downstate and centrifugal state. Materials are crushed due to the dislocation motion. Rod mill and tube mill usually work in this state.
