The WS series sand mill is a machine for solid-liquid phase dispersion grinding of powder materials and liquid materials. Widely used in coatings, dyes, inks, photographic, materials, pharmaceuticals and other industries. The machine is novel in design, compact in structure and produced in a closed state, which effectively prevents dry crust and solvent evaporation of the material. In addition, the machine does not need a special installation foundation, and the installation position can be changed as needed at any time.
