Data from ball mills with a wide range of diameters are analyzed using detailed mathematicalnumerical models. analysis shows the relative power inefficiency of large ball mills is due to their inefficient breakage of coarse particles. the models developed can be used to scale-up mill behavior. the behavior of large mills at bougainville and pinto valley is compared.

The powder cooler from christian pfeiffer improves product quality through cooling, the grinding ball sorting machine optimizes the ball feed in the grinding plant. our foreign matter trap prevents heavy and oversized material from returning into the grinding process and protects the separator against damage.
The production process culminates in two ball mills. each day, the 15-meter-long machines grind up to 5000 metric tons of clinker the result is ready-to-use portland cement. in each mill, two pinions and gear units transfer the force from two 2250-kilowatt asynchronous motors to a girth gear that is directly connected to the ball mill surface.
The types of mills are distinguished by their working principles by pressure, impact, hammer, or shear. mills could be equipped with a screen for grain size control and separation. the fam product range includes impact mills, roller mills, hammer mills, ball mills and rod mil.
This paper compares the surface roughness along and across the feed directions produced by toroidal, ball nose, and flat bottom end mills. the study is conducted numerically and by cutting tests of aluminium. the results show that the toroidal cutter inherits the merits of the other two cutters it produces small scallops across the feed direction, and low roughness along the feed direction.
