Abstract

Process and machine for grinding or crushing by pressure to very fine size materials, particularly those of high hardness or abrasives, without causing contamination of the ground product, characterized by making two consecutive grindings without the layer of compact material that forms in the first milling reduces the fragmentation effect in the second milling, with no screening or manipulation taking place between the two phases.
