caculations of ball mill project efficiecy performance

Design and Fabrication Of Hammer Mill Mechanical ProjectThe objective of this project is to carry out a design fabrication and testing of a hammer mill, which will be used for grinding agricultural produce and mineral resources .The profile of the throat of the machine is redesigned to give better performance that was hot nit achieve when the machine was carrying the straight profile. ...How to Measure Grinding EfficiencyThe first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills. Figure 1. The first example is a comparison of two parallel mills from a daily operating report. Mill size 5.03m x 6.1m (16.5′ x 20′ with a ID of 16′). This example shows that Mill 2 is slightly more efficient than Mill 1 even though it has a higher power ...
