<p>A multiple barrel chamber for a media mill where the media mill is used to grind and disperse pigments for paint, coating, ink products, and other pigment-vehicle fluids, as well as grinding and dispersing other particulate matter. More particularly, a three barrel grinding chamber (20) including a lengthwise rotatable shaft (30, 32, 34) in each barrel portion is disclosed. Each shaft includes a disc array overlapping an adjacent disc array. Utilization of variable speed bi-directional motors, preferably independently controlled, to rotate each shaft allows impact, tack-shear, and slurry grinding to be accomplished with one media mill. The grinding efficiencies achieved far exceed those of conventional media mills. Media mill grinding discs are also disclosed.</p> |
