Exploring ball size distribution in coal grinding mills

Tube mills use steel balls as grinding media Due to wear in the abrasive environment it is necessary to charge new balls periodically to maintain a steady balanced ball charge in the mill The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the mill capacity and the milling efficiency12022017· In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals In the chemical and process industries, grinding is an importantBall Mills 911 Metallurgist80) for grinding test of coal particles were chosen before milling in a ball mill The d 80 sizes of coal particles of feedwere4,1,and065 mmAftergrindingd 80 ofthesesizes were 165, 07, 025 mm Grinding tests were performed in a laboratory scale ball mill of 375 cm long and 27 cm diameter The size of the balls used were of 25 cmGrinding analysis of Indian coal using response surface
