How the Three Roll Mill Works

The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example; the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll at 270 rpm. 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 milled material is removed from the apron roll by a knife that runs against the roll.

Product specification

Main feature

1. High precise (minimum 1μm, depend on materials)

2. Easy-cleaning roller.

3. Variable speeds

4. Hopper(optional)

5. Adjust the gap between two rolls by single hand,

moment balance, easy to operate.

6. Import Nanoscale ZrO₂ ceramics rollers about 99.8%

7. Ceramic roller precision: concentricity < 2 micron,

linear degree < 2micron, exterior planeness < 0.2micron

Application

Our three roll mill is widely used for printing ink & coating, new material, chemistry, pharmacy & medical treatment,

electronic industry, food and cosmetic. Like paint, ceramic paste, resin, chocolate, lipstick and so on.

Especially for high viscosity and good fineness products.
