### Difference Between Sag Mill vs Ball Millmech4study

Oct 12 2017 · SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9 to 20 .This process takes place inside the large rotating drum of SAG mill which is filled with balls partially. 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.

### Ball Mill Load feedPage 1 of 1

Dec 03 2010 · Re Ball Mill Load feed. Dear GKS You are correct in stating that main drive kw only increase when less grinding media charge and small size of grinding media w.r.t. feed size and feed rate. However it was to be stated in my reply that Kwh/t of material increases in chocked condition of the mill as there is no output from the mill. Warm regards 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.
