The fineness of grind and/or the development of color determine the equipment used in dispersion. High speed dispersers (HSDs) are used mainly for pre-mixing the initial pigment powder with liquid [3]. The pigment particle size is reduced in HSDs to < 250 μm. Bead grinding is a secondary dispersing method for pigments that …
