Solids | Choose the Right Grinding Mill | Chemical Processing

Sep 13, 2010 . In most industries size reduction falls into two general categories: crushing and milling. Crushing typically means reducing large chunks to sizes about 1/2 in. to 3/4 in. in diameter or smaller. Milling usually means reducing material to sizes in the low micron or even nano-size range. Crushing mostly is done.
