The lab tri-roll mill is mainly used for the grinding and dispersion of various kinds of paints, inks, pigments, plastics, cosmetics, soap, ceramics, rubber and other high viscosity liquid and paste materials. The grinding and dispersion effects are achieved by the friction between the surface of the horizontal three rollers and the friction of different velocities.

Product features:
1. It is suitable for processing high viscosity materials;
2. Through manual adjustment of roller clearance, the mechanism is simple and reliable;
3. The steel drum can be hollow and water cooled;
4. The roller has high hardness and wear resistance.

Three rollers are mounted on an iron frame, who’s center is on the line. Horizontal or slightly inclined installation is acceptable. It gets the effect of grinding through the surface of the horizontal three rollers squeezing each other and the friction at different speeds. The steel drum can be hollow. The material is added between the middle and back rolls. Because the rotation direction of the three drums is different (the speed increases from the back forward), this produces a good grinding effect. The material was scraped off by a scraper which is put in front of the preliminary roller.Generally, the tri-roll mill is made of cold hard alloy cast iron. The surface hardness reaches above HS70°. The diameter of the roller is high precision ground and the material can be grinded to about 15μm. It can produce uniform and fine quality products.
