## Ball Mill Operating Speed Mechanical Operations Solved

Ball Mill Operating Speed Mechanical Operations Solved The critical speed of ball mill is given by where r radius of ball mill r radius of ball for r 1000 mm and r 50 mm n c 307 rpm but the mill is operated at a speed of 15 rpm therefore the mill is operated at 100 x 15307 4886 of critical speed if 100 mm dia balls are replaced by 50 mm dia balls and the other conditions Rpms On A Ball Mill And A Star Rolling Machine Okay im considering building a combo machine for ball milling and star rolling the thing im confused about is the rpm of the drums i always thought a ball mill should be fairly slow because rock tumblers that ive seen are fairly slow maybe 60 revs per minute i guess im wrong ive seen recommendations of much higher speeds of Variables In Ball Mill Operation Paul O Abbe The first problem will ball mills is that we cannot see what is occurring in the mill the other problem is that many of the independent variables are nonlinear or have paradoxical effects on the end results in ball milling of dry solids the main independent variables are mill diameter mill speed media size solids loading and residence time
