  • Ball mill - Wikipedia

    A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

    The race also yields slightly where each ball presses against it. Thus, the contact between ball and race is of finite size and has finite pressure. The deformed ball and race do not roll entirely smoothly because different parts of the ball are moving at different speeds as it rolls. Thus, there are opposing forces and sliding motions at each ball/race contact. Overall, these cause bearing drag.

    01.07.1981· Figure 1 shows a ball-and-race mill [1] in which heavily loaded balls roll in a rotating race, subjecting powder in the race to high crushing forces. Feed enters the center of the rotating table and is thrown through the race by centrifugal action. The ground material passes over the rim of the rotating table and is swept up by air flowing at high velocity through the annulus between the rim ...
