How Commercial Flour Mills Work

Cleaning and conditioning – ridding the grain of all impurities and readying it for milling. Crushing or breaking – breaking down the grain in successive stages to release its component parts. Reduction – progressive rollings and siftings to refine the flour and separate it into various categories, called streams.

Solids | Choose the Right Grinding Mill

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 dry while attrition milling may be ...
