How to Operate a Grinding Circuit
Handling the Grinding Circuit: IF YOU FIND: IT MEANS: YOU SHOULD #1. Ball-Mill Feed. Finer: Mill will grind faster, classifier overflow will thicken and get coarser. Increase classifier water to raise circulating load; perhaps raise mill feed. Coarser: Mill will grind slower, classifier overflow will thin out, get finer. If fed too fast, a grate mill may plug.
How to Calculate Grinding Mill Operating Efficiency
Wi = Work Index determined from crushing and grinding tests. P = The size in microns (micrometers) that 80% of the product is finer than. F = The size in microns (micrometers) that 80% of the feed is finer than. When accurate mill ore feed rate in dry tons per hour, mill power draw in kilowatts,...
