Mill output depends on the distance between the rolls and the viscosity of the millbase the three-roll mill can handle viscosities up to 200 poise and therefore can be used for materials not suitable for ball and sandmills due to the introduction of easily dispersed pigments and fillers three-roll mills have lost some of their importance
Dispersing with slot ball mills with most types of attrition mills the beads often become obstructed in front of the separating system the as the pigments vary in dispersing hardness the dispersing process (bead size and dispersing time) should be adjusted to suit the pigments it might be advantageous to disperse
