Media and product ball mill loading guide percentages are based on total volume of cylinder note with media load at 50 voids are created equal to 20 of cylinder volume these voids are filled when product is loaded into the mill
Jan 30 2018 ball milling is a grinding method that reduces the product into a controlled final grind and a uniform size usually the manganese iron steel
Ball mills tumble iron or steel balls with the ore the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds the feed to ball mills dry basis is typically 75 vol ore and 25 steel the ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones
Why do ball mills have such high circulating loadsthe ball mill grinds the cyclones separate but the pump neither grinds nor separates so what is the purpose of having such a big pump to maintain high circulating loads in our grinding circuita recent grinding bulletin addresses this question f
Selection of volume of ball loads in continuous dry open circuit grinding the tests reported in tables 19 and 20 were made in cooperation with a large cementmanufacturing company that wished to obtain more grinding for the power expended the ball load in its clinker grinding mills was 18 percent of the mill volume and the company did not deem it consistent to increase the ball load because
