Abstract

A high pressure roller press formed between opposed cylindrical rollers mounted to perform interparticle crushing or product bed comminution in the nip and having pockets in the surface of a size to retain compressed fine grained material which is pressed in the nip with the compressed material in the pockets being retained for full revolutions of the rollers and coacting with hard portions between the pockets to form the product bed comminution against material passing through the nip and drawing material into the nip.
