However, grinding balls are perfectly suited to the attrition of materials and powders. This is called a ball mill or grinding machine: the balls and the product to be ground are placed in a container, which is set in motion, in rotation. The attrition is then achieved by a mechanical grinding mechanism due to the friction of the balls on the ...

The kinetics of dry grinding of several cement clinkers and two coals were investigated in a laboratory tumbling ball mill. The kinetic process is first-order at first, but the rates of breakage decrease as fines accumulate in the bed. It was demonstrated that the slowing of the breakage rates applies to all sizes in the mill, indicating that ...

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
