Sower three roller mill is mainly used for refining high viscosity materials in paint, inks, pigments, plastic and other industries. It is especially suitable for processing products with high viscosity and fine particle size. The surface of three roller mill is squeezed each other and the friction caused by different rotating speeds makes the adjacent rollers produce strong shear force, forcing the materials to be fully dispersed and grinded. 1. The grinding fineness is one of the best in wet grinding equipment; 2. The machine adopts double vane pump and is controlled by hydraulic pressure; 3. The basic feeding and discharging of the machine and the fineness control of the materials are all controlled by hydraulic pressure, with high automation, simple operation and safe use; 4. The hydraulic system adopts plate structure to make its layout more reasonable; 5. The roller is made of special alloy material with high strength, high hardness and wear resistance; 6. The roller clearance can be adjusted;
