Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

For ball mill, Bond (1958) was proposing an empirical formula giving the top size of balls (make-up balls) DM function of the feed size xG (80% passing size - m), the ore true specific gravity sg, the ore Bond Work Index Wi (kWh/st), the fraction of critical speed fc and the inside mill diameter D (m):
Jun 01, 2018 For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.
where db.max is the maximum size of the feed (mm), σ is the compression strength (MPa), E is the modulus of elasticity (MPa), ρ b is the density of material of balls (kg/m 3 ), and D is the inner diameter of the mill body (m). Generally, a maximum allowed ball size is situated in the range from D /18 to D /24.
