Abstract: Ball drum mills area commonplace in grinding offerrous and non-ferrous metals, and a cement production in the world. A significant shortcoming of these mills is high specific energy consumption on grinding. A material grinding process in ball drum mills is executed by grinding bodies that move in a transverse.
May 6, 2004 . In this paper, a new approach for the calculation of the power draw of cement grinding ball mills is proposed. For this purpose, cement grinding circuit data including the operational and design parameters were collected from 14 industrial ball mills, ranging in diameters from 3.2 to 4.8 m. The ball loads.
Charge and power Calculation of charge. D: Effective . :5: Arm of gravity in relation to mill diameter [-l n: Rotational . Critical speed: The critical speed nc is the speed, where the centrifugal force at the mill lining is equal to the gravitational force: Normal mill speeds are 70 — 80% of the critical speed.

When calculating the recommended ball top size from Bond's formula (Bond, 1961), the size for regrind applications is much lower than 25 mm. Today, the barrier for small grinding media is broken. They are best suited in regrind application. The size of grinding media is one of the most important variables affecting the mill.
