Abstract

A mechanism and method for the comminuting and grinding of brittle grinding stock including a roll press with the material passed from the roll press to a deagglomeration drum which co-rotates with the tube mill. The material from the deagglomeration drum is passed to the tube mill and the material from the tube mill being passed to a separator. In one form the material from the separator is passed to a second separator and the coarser products from the second separator are led back to the tube mill with an airstream conducting the finer material from the tube mill to the first separator.
