Grinding ball milling machine: the principle of plastic ball grinding machine can not only plastic grinding ball and plastic ball, can also be processed ball, copper ball, aluminum ball, glass ball, ceramic ball ball products, ball milling machine can grind ball milling machine because the ball is useful to the grinding ball special, special the wheel's circular groove, there is a corresponding plate is also provided with the same slot, so to the processing of plastic ball just before the two slot work below the wheel is rotating at high speed, per minute can reach 1000 to 3000 rpm, speed can be adjusted, the plastic ball through high-speed non-stop friction and grinding wheel, grinding the final product size, but to pay attention to the ball mill grinding out the ball than the actual needs of the ball out around 0.08MM, because the next polishing process, will wear on the ball , so to set aside the amount of wear, grinding the ball and then after the three processes of polishing is finished plastic ball.
