ball mill filling volume

ball mill - an overview | sciencedirect topics

ball mill - an overview | sciencedirect topics

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 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length… Read more
