Laboratory Size Batch Ball Rod Mills72 Кб. They are of a sturdy, rugged design to handle frequent use with hard materials. The batch ball and rod mills require a drive roll to rotate them at the proper grinding speed, usually 60 - 75 of the critical speed for ball mills and 50 to 90 of critical speed for rod mills.
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 mills have been successfully run at speeds between 60 and 90 percent of critical speed but most mills operate at speeds between 65 and 79 percent of critical speed Rod mills speed should be limited to a maximum of 70 of critical speed and preferably should be in the 60 to 68 percent critical speed.
