the coal lump size fed for grinding shall not exceed mm. mills are manufactured with right or left location of drive, if facing the mill end from the ring gear unit. technical characteristics shbm ball tube mill with crusher- dryer crushing impact & attrition 2.5 2.5 low-high 1.25 ball tube mill without crusher- dryer impact & attrition 2.5 0.75 low-severe 1.25 atrita crushing, attrition &may 01, 2014 It has been shown that mill capacity is linearly correlated to media surface area, thus using mm balls as top size which leads to a fine ball size distribution in the mill is evidently a better approach than the current approach of using larger ball sizes. however the fact that the coal feed to this plant is known to be contaminated with a small fraction of hard-to-grind stone, which will strongly
Effect Of Ball Size Distribution On Milling
a.7 results of size analysis for 2360 1700 microns coal using 38.8 mm balls a.8 results of size analysis for 22400 19000 microns coal using 49.2 mm balls a.9 results of size analysis for 9500 6700 microns coal using 49.2 mm ballsthe four most common types of coal pulverizers are: ball-tube mills. this type of mill consists of a rotating tube filled with cast alloy balls. coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. impact millsaug 02, 2013 In grinding, selecting the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a mineral processing engineer aka metallurgist to do. often, the ball used in ball mills is oversize just in case. well, this safety factor can cost you much in recovery andor mill liner wear and tear.
