In horizontal mills, the media charged to the mill usually occupies from 75% to 90% of the mill empty volume. In vertical mills, the media charge can be in the 60% range. Product flow through the mill will carry the media toward the mill exit unless it is counteracted by internal flow patterns induced by the agitator system.

Beadmill. Beadmill is an integrated production machine capable of producing a finely dispersed finished product. The three involved processes of premixing, grinding and dispersing are combined together in this machine. The principle used by the bead mill is that of shear created within in mass -differential flow of product and grinding media.

The invention relates to a stirring mill in whose grinding tank, provided with an inlet and an outlet, and charged with a load of grinding beads, a stirring shaft (stirring mechanism) provided with stirrers, is rotatable, on which, for holding back the grinding beads a separator is mounted ahead of the outlet and is provided with radial openings.

Frequently Asked Questions. Q.1: My mill freezes up and won't start, why? There are several reasons why a mill will freeze up when not in use, but the most common is that it was left with too dry a bed of media in it. This might be just that the operator left the mill running after the pump had nothing more to feed it and the discs act as low ...
