Nov 26, 2019 And because the ball mill feed grain size is larger, ball mill feeding groove must have a larger slope and height, so that feed smooth. Bearing. Since the power of the autogenous tumbling mill is relatively small, it is appropriate to choose dynamic and static pressure bearing. The ball bearing liner is made of lead-based bearing alloy, and the back of the bearing is formed with a waist drum to form a

Within 20 seconds of entering the pellet mill, feed goes from an air-dry (about 10-12 percent moisture) condition at ambient temperature, to 15-16 percent moisture at 80-90C. During subsequent compression and extrusion through holes in a ring' die, friction further increases feed temperature to nearly 92C
