Three roll millWikipedia

A three roll mill or triple roll mill is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it.

Ultra-high shear mixing: an alternative to three roll milling

Three roll mills, a classic technology . Traditional three roll milling remains to be one of the best methods for preparing very fine particle dispersions in paints, inks, cosmetics, ointments, . and the shear forces between adjacent rolls generate the dispersion.

Home of the Other Three Roll Mill Manufacturer

A Three Roll Mill has three horizontally positioned rollers. Each roller rotates in an opposite direction from the adjacent roller with a tiny gap between them, creating tremendous shear force that can finely disperse, mix, refine or homogenize viscous materials.

Three Roll MillIndustrial Mixers and Blenders

When ROSS produced the first Three Roll Mill more than 80 years ago, we revolutionized pigment dispersion — with superior consistency and finer dispersion than ever before. . Material is transferred from the center roll to the apron roll by adhesion. The dispersion is achieved by the shear forces generated between the adjacent rolls. The .
