Energy-Efficient Technologies in Cement Grinding

The pressure arrangement of the grinding rolls is hydraulic. The mill feed is introduced into the mill from above, falling centrally upon the grinding plate; then it is thrown by centrifugal force underneath the grinding rollers. A retention ring on the periphery of the grinding table forms the mill feed into a layer called the grinding bed.

Foods & Milling MeTL

Milling to produce white flour removes most of the bran layers and the germ, which together amount to about 15% of the wheat grain. This means that, depending on the milling technique, not all the bran can be separated, and up to 50% of the germ is retained in the white flour. Milling is now much more than the simple Grinding of grain.
