## Maximum feeding size of ball mill

where db.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

• 3 size reduction - SlideShare

Sep 21, 2019 The load of balls in a ball or tube mill is normally such that when the mill is stopped, the balls occupy about one-half the volume of the mill. The void fraction in the mass of balls, when at rest, is typically 0.40. When the mill is rotated, the balls are picked up by the mill wall and carried nearly to the top, where they break contact with
