J B the fraction of the mill volume occupied by the bulk ball charge. If the masses of the rocks and balls were M R and M B respectively and V M the internal volume of the mill then the fractional volume of mill occupied by the bulk rock and grinding media will be 7.5 J R M R S V M 215 1 1 7.6 J B M B B V M 215 1 1
Our products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
Ball fraction of mill volume Table 2 shows that for nearly the same lling measured physically the mill power with smaller media is signi catively reduced. Therefore if the power is kept on target when adding small media the charge will increase and may cause mills overcharging specially if the charge is already at the trunnion level.
