Variables Affecting Grinding Mill Power. Previous Next ... There is nothing in the power-speed curve of a big mill to indicate the speed at which centrifugalizing begins, but squirrel-cage tests have shown that maximum power is consumed at a much lower speed than is necessary to centrifugalize the balls.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

Maximum power is drawn by a mill when the charge occupies approximately 50% by volume. The power curve becomes very flat in the range above 45%. As a result, mills are seldom run with charge levels greater than 45%. In rod mills, the charge is swollen by particles of feed which separate the rods. If the mill is shut down immediately after the feed is shut off, the charge level will be greater ...
A gristmill (also: grist mill, corn mill, flour mill, feed mill or feedmill) grinds cereal grain into flour and middlings.The term can refer to both the grinding mechanism and the building that holds it.
The grinding curve is the product size as a function of feedrate, for a fixed feed size. It is proposed that for each new milling condition, in this case a change in the percentage of ball scats in a mill, the peak in the grinding curve must be sought, and that must be used as the comparative test condition.
