calculation of performance of ball mill

Ball mill performance

Ball mill performance – is an indicator for showing the material amount passing through the mill per unit time. The drum mills productivity depends on the initial and final products size, the ore grindability, the mill size, the mill type, mill speed, the grinding balls degree filling, the circulating load value, and the classifier efficiency.

Calculate Top Ball Size of Grinding Media - Equation & …

The development of the ball mill during the twentieth century has been described as the most significant development in the machinery for performing the grinding of ores (Lynch and Rowland 2006). A key part of the implementation of ball mills was the development of the ability to predict their performance in the plant based upon grindability data from standardized tests performed in small ...

Addition of pebbles to a ball-mill to improve grinding …

The performance indices of the ball-mill (base case) were similar, (i.e. productivity was measured in terms of kg of new fines produced, but the size distribution of the product was finer. The results from the additional experiments imply that the replacement of balls by pebbles to facilitate composite milling is not a straight forward exercise.
