Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding.
For the past three decades the vertical roller mill has emerged to be the preferred choice for grinding raw materials. With the grinding capacity of a vertical roller mill and the ability to dry, grind and sort in a single unit, the vertical roller mill offers a definite advantage over the ball mill system [10].
The main structure of the ball mill includes a solid cylinder, which contains grinding balls of different materials and sizes. The motor and transmission system is used to drive the rotation of the cylinder, while the feeding and discharging system is responsible for the introduction of raw materials and the discharge of finished products.
