Abstract
A particulate grinding method and device applies different force fields to drive the grinding medium and the particulates move in different routes but collide only at a grinding area so that they are separated naturally without conventional screening mechanisms, such as a screen or a gap, and prevented from the limitation of mechanical size of the components. Moreover, the invention is applicable to finer particulates. The circulation of particulates is not limited by any small gap of screening mechanisms, so the particulates ill not block the separator.
