Feb 08 2017 the operating principle of the ball mill consists of following steps in a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls then discharge of ground material performed
Ball mills in producing the final product particles finer than 74 m was 5538 and 4462 respectively that is the sag mill produces about 1076 more than the ball mill in the final product the average consumed energy at sag and ball mills to produce one ton of final product was 2316 kwht and 3605 kwht respectively
This entry is when the torque curve on your cnc machine is the most important older cnc machines where designed to quickly reach peak torque between 1200 3000 rpm and then drop off newer high speed machining centers hold constant torque we like constant torque because of the unique geometry our tools perform best under constant torque
