Rod Mills How They Function Mine

The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50 to 95 of the critical speed. The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the ...

Ball Mill Operation Grinding Circuit Startup Amp Shutdown

Feb 01, 2016 The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silent.
