S Series Three-Roll Mill

Welded high-quality steel plate body with oil-immersed gear drive and gear handwheel. Attractive, easy to operate, long service life - especially for grinding high-viscosity products requiring fine particle size.
Working Principle
Three rolls rotate at different speeds (slow/medium/fast ratio from 1:2.3:5.5 to 1:3:9), subjecting material to intense shear and compression in the roll gaps for progressive particle refinement. Roll gap adjustment precisely controls fineness - ideal for high-viscosity paste grinding.
