Ball milling A device used to reduce the particle size of materials, bodies or glazes. 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.
Jun 23, 2012· I'm working on a large Deckel CNC mill. The Z axis ballscrew moves the table, which is probably upwards of 2 tons, and has no counterbalance. The balls in the ballscrew on the machine have failed, and have pitted a portion of the ballscrew where it operates the most.
