Three Roll Mill. Three Roll Mill system consist of 3 rollers that are positioned horizontally. Rollers rotate in opposite directions from each other and have a very small gap between each other. This movement and gap between the rollers create a shear force to mix, disperse, refine and homogenize materials having a certain viscosity.

Three roll mills can be used to process a wide range of products with diverse theology- from low viscosity materials of 200 cPoise to thick paste of more than 1,000,000 cPoise. Three roll mills enable a medium or high viscosity product to be dispersed with minimal liquid. Since liquid materials do not have to be dispersed, they can be added later.
