2003-4-1 · In minerals processing, four grinding “stages” can be identified, based on the size of the grinding product. Traditionally, grinding to 80% passing 75 μm is regarded as “conventional” since many operations grind to that size. Regrinding is considered to produce the particles finer than 75 μm down to 30 μm.
