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.

Explain the use of rod mills in mineral industry. The product size distribution is narrower than a ball mill but significantly coarser. Most are overflow discharge type. The Rowland and Kjos equation indicates that power draw is a function of the fraction of the critical speed for the mill.
