ABSTRACT:
An air separator is provided with a rotor positioned above three concentric vessels. The rotor and a plurality of entry ports segregate comminuted material into the three vessels. An exit port from each vessel directs the separated comminuted material for further comminution processes, such as to a ball mill or a roll press, or for use as a final product.
