maintaining the vortex during this process. In order to maintain the to a point approximately midway between the center of the tank and its side. Restart the disperser and increase speed to obtain optimum the liquid. Adjust impeller speed and height to form a deep vortex. Add dispersing speed of about 4500 to 6000 peripheral feet per minute. As a vortex while adding the pigment it may be necessary to adjust the height general rule, proper dispersion can be obtained if the impeller blade is one third to one quarter the diameter of the tank and the blade is positioned between one third and one and one third diameters above the tank bottom. During the high speed dispersion phase one or more shallow vortices are obtained instead of the deep vortex required during the pigment addition phase. Maintain dispersion speed for 10 to 15 minutes to obtain a Fineness of Grind reading of 4.5 to 5 NS. This dispersion is then added to the mill base in the formu
