The Grinding Media of Ball Mill

When the ore and water are fed into the ball mill cylinder from one end of the hollow shaft, discharged from the other end, and the cylinder rotates to the specified speed of ball mill products, the steel ball or bar together with the ore go up to a certain height with cylinder, then fall and slide down breaking away from the shell under the effect of centrifugal force and friction of Ball Mill Equipment. Soon afterwards they rise again with the cylinder to the same height of ball mill products, and then fall in regular intervals, making the ore ground-up by the impact force and grinding effect. The ground-up ore and water form slurry (wet grinding) of ball mill equipment, which is discharged by the hollow shaft on the ore discharge end, thus the ore grinding is finished.

Following is the Ball Mill technology update introduction: Previously, the feeding of the Ball Mill Machineunits the spoon head with the feeder. Due to the clumsy spoon head, the self-weight, the big eccentricity, and the friction and impact with the deposition ore sand when coping down, the ball mill emerges periodic eccentricity load and impact load. Thus the electric motor of the ball mill operates under the varying load situation which increases the capacity and makes the current fluctuates substantially in the variable motion of half cycle speeding up, half cycle slowing down. The periodic eccentric load and impact load have much affect on main bearing attrition, the stress of the barrel attachment bolt, the mesh of the gear wheel and the pinion, and the heat emitting of the electric motor and shorten the ball mill service life. And the ball mill solution is that turning down the accelerator properly to decrease the sprout oil mass. When adjust the accelerator, it should be done by the experienced people. As in case the accelerator is turned down undersize, the lubricant oil quantity of the bearing will be insufficient and the friction force will be increased which makes the main bearing...
