The three roll mill is mainly used for various kinds of paste such as paint, ink, pigment, plastic and food. The grinding effect is achieved through the surface of the three horizontally arranged rollers and the friction of their different speeds. Generally the material meets requirements after grinding twice; difficult material must be ground several times. The final processing fineness reaches about 3-18 µm (measured by fineness scraper).
