Factors Affecting Ball Mill Grinding Efficiency

Apr 22, 2018 a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills

Effect of ball size and powder loading on the milling

Dec 01, 2013 In this figure, the negative influence of the smaller ball size on the milling efficiency is drawn by an arbitrary positive slope with ball size rather than the dependency of d 4, because in an actual dynamic ball mill situation, the balls already existing in the turbulent medium is moving rather than in stationary state, and thus the effect of

where d b.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 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 D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
