Cumulative Rates Ball Mill Model. A ball mill is a horizontal cylinder partly filled with steel balls or occasionally other shapes that rotates on its axis, imparting a tumbling and cascading action to the balls.Material fed through the mill is crushed by impact and ground by attrition between the balls.The grinding media are usually made of high-chromium steel.

an alternative solution to the grinding equation in. Apr 01, 2005· The size-discretized cumulative batch grinding equation can be written as: (9) d P i (t) d t = ∑ j = 1 i-1 B ij s j [P j (t)-P j + 1 (t)] 1 . i ⩽ n; P 1 = 1 by definition, where P i (t) is the cumulative mass fraction of the mill contents finer than the size x i at time t; and the equation simply expresses the mass balance ...

Abstract The number of size classes used in a cumulative rates model to simulate a grinding mill circuit was reduced from 25 to 5. The model remains qualitatively and quantitatively accurate when 5 size classes are used, with variations of less than 5% from the base case of 25 size classes. If the model is implemented in a model-based controller, the reduced number of size …
