The object is to bring the ore to the mesh-of-grind called for by the concentrating section of the mill, and this is best done in separately controlled stages. Often the primary grinding mills must work vigorously on a quickly passing stream of ore, and the secondaries more gently and with longer retention of the pulp.
2020-8-20 A population balance model of grinding mills 3 mF(x) of balls of size xat the in ow. The dimension of mF(x) is the inverse of size, since integrating mF(x) over a size interval x2 [a;b] yields the relative frequency of balls having size between aand b. This relative frequency is a dimensionless number between zero and
