how do cement ball mills work

Each time the grate enters the mill charge, the horizontal force of the load in the mill deflects the grate. This stretches the rubber and forces any large material caught in the grate opening along through the grate slot. As the grate leaves the charge, the rubber assumes its original shape. This diaphragming action works the large particles ...

Cement manufacturing -brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

How does a cement ball mill work? A cement ball mill works by rotating a cylinder filled with a grinding medium such as steel balls, thereby creating a tumbling and cascading motion of the balls. The material to be ground is fed into the cylinder through a hollow shaft at one end of the cylinder. As the cylinder rotates, the grinding media ...
