Grinding Media Amp Lining Media Liner Wear Rate Modelling

the cost of replacement of the metal worn from the working surfaces of the balls and liners of a mill often represents a considerable fraction of the cost of operation of the plant and so is of some real economical importance. In spite of this importance, however, the amount of information in available on this subject is amazingly small and, unfortunately, is insufficient to form the basis of submitted to minerals engineering 119 prediction of slurry flow within the grinding chamber and discharge from a pilot scale sag mill paul clear and rob morriso siro mathematics, informatics and statistics, private bag 33, clayton south, 3168, australia.
