How to design a Ball Mill Grinding Classification Circuits ...
You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell Cmodel or Nordberg equation to get the RPM that corresponds to 75% for that mill diameter.

Ball Mill Grinding Theory Crushing Motion/Action Inside
It seems certain, however, that the ballmill will crush to 200 mesh a considerably greater tonnage when the proper classification is provided. Since in previous tests the mill has crushed 7½ T. per hr. from ¼ in. to 200 mesh, it seems possible that it will crush at least 8 T. per hr. from 48 to 200 mesh.

How a Grate Discharge Ball Mill Works 911 Metallurgist
Each time the grate enters the mill charge, the horizontal force of the load in the mill deflects the grate. This stretches the rubber and forces any large material caught in the grate opening along through the grate slot. As the grate leaves the charge, the rubber assumes its original shape. This diaphragming action works the large particles ...
