Jan 01, 2019 · Small balls facilitate the production of fine material, although they do not deal so effectively with the larger particles in the feed. The limiting size reduction obtained with a given size of balls is known as the free grinding limit. For most economical operation, the smallest possible balls should be used. (e) The slope of the mill

Kicks law: putting p = 1, then integration gives: Writing C = KKfc, then Kicks law, is obtained as: This supposes that the energy required is directly related to the reduction ratio L1/L2 which means that the energy required to crush a given amount of material from a 50 mm to a 25 mm size is the same as that required to reduce the size from 12 mm to 6 mm. Bonds Law: Neither of these two laws permits an …
