3. The ball mill is of good quality. The better the quality of the ball mill, the more stable the performance of the ball mill will be during operation. In addition, as for the lining plate of the ball mill's wearing parts, the quality of the lining plate affects the overall production efficiency of the ball mill. As we all know, the lining ...
A ball mill is simply a container that is filled with pebbles (either of porcelain or stones e.g. Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them. Ball mills can be continuous or periodic, they can be small or gigantic, low-speed ...
