Improving mixing, quality with dispersions. - Free Online Library

A high speed disperser may provide greater agglomerate reduction. The greatest agglomerate reduction can be obtained with high shear equipment such as the three-roll mill (high viscosity pastes) or horizontal pebble mill (moderate viscosity pastes). Dispersion quality or de-agglomeration is often measured by the Hegman NS grind test (ASTM D-1210).
