2012-11-26The 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 ...
COMMON EQUATIONS FOR OPTIMAL PERFORMANCE Too high of a speed or too light of a feed leads to reduction in tool life. Speed is measured in feet per minute and is referred to as cutting speed, surface speed, or peripheral speed. In the tables below, the relationship of peripheral speed to the diameter of the tool, and the rotational speed of the
