bar mill vs ball mills

Ball or bar mills- on what does it depend? – COMESA

The ball mills can perform in open or closed circuits with classifiers or cones and be classified according to their discharge: by stump or grill. In comparison to bar mills, the reduction is an outcome of the specific contact instead of the linear contact. The crushing with ball mills is not selective, they produce finishes with a 35 mesh and ...
