When used with grinding media ("balls") they are called SAG (semiautogenous grinding) and when only rock is present they are called AG (autogenous grinding) mills. The most common secondary mill is a ball mill in which relatively fine feed particles ( mm top size) are ground in a charge consisting predominantly of steel balls.

E = K R f c (1/L 2 1/L 1) Where: E=Energy, K R =Rittinger's Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 =reduced length. Kick's Law states that the energy is proportional to the size reduction ratio. The equation for Kick's Law can be written as: E = K K f c log e (L 1 /L 2)

Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder. A typical processing line at a mine might consist of a crusher followed by a SAG mill followed by a ball mill. In this context, the SAG mill and ball mill are considered grinders rather than crushers.
