How to Measure the Impact Forces in Ball Mills

Data from drop ball tests seem to be fairly well confirmed by in-mill tests with the hollow instrumented ball which, although heavier, is larger in diameter, less convex, softer steel, and strikes either the tumbling mass of ore and balls or descending mill liners. The ball was placed and recovered in the feed end of the mill where impact is known to be less severe.
