The SH series granite three-roll mills (SH150, SH200, SH260) offer multiple roller diameters to match throughput needs. Natural granite rollers provide superior hardness and cooling, ideal for high-viscosity printing ink, paint, pigment and putty. Differential-speed grinding with adjustable pressure yields uniform fineness, and the heavier SH200/SH260 models support larger batch capacity for medium-scale production.
