Jul 24, 2021 Calculation Of Ball Mill Medium Loading. The volume of the grinding medium is the percentage of the effective volume of the mill, which is called the filling rate of the grinding medium. The size of filling directly affects the number of shocks, the area of grinding and the load of grinding medium in the grinding process.
the model requires inputs of the liquid and ore specific gravities as well as ball filling, total filling and the solids by weight of the discharge slurry. The ball filling relates to the volume including voids that the balls occupy when the mill is completely ground out, ie there is no ore in the mill.
The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 3035 of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.
