Ball Mills An Overview Sciencedirect Topics
Where d bmax is the maximum size of feed mm is compression strength mpa e is modulus of elasticity mpa b is density of material of balls kgm 3 d is inner diameter of the mill body m generally a maximum allowed ball size is situated in the range from d 18 to d24 the degree of filling the mill with balls also influences productivity of the mill and milling efficiency
