Abstract

Comminution of water- insoluble dyestuff is the most imporiant process in the courseof the dyestuff production. Thecomminution procedure and principle are also rathercomplicated. The technical problems such as comminution equipment, dispersing agent, comminution technique are determined correspondingly on the basis of the physical and chemical natures of dyestuff in a comminution system. In this paper, the ultrafine comminution principle of dyestuff and the optimum operation technologies were discussed.
