Three roll mill for sale is a type of grinding machine used to grind, disperse, or homogenize viscous materials such as paints, inks, greases, and ointments. It is mainly used in the production of printing inks, paints, and pigment pastes. It is also used in the production of cosmetics, pharmaceuticals, adhesives, and other viscous materials. Do you know how three roll mill for sale works?

The Working Principle

Three roll mill for sale 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.

Roller Material

The selection of roller material depends on the application. For most application such as cosmetics, chocolates, adhesives, and printing inks, steel rollers will work just fine. They are commonly cheaper than other types of rollers. For applications where metallic contamination is a concern, or when one or more ingredients would react with metal, porcelain/ceramic rollers are recommended. Examples include some thick film pastes, dielectric inks, and pharmacy ointments.

Roller Pressure and Speed

Three roll mill is operated by adjusting the rollers’ gaps mechanically or hydraulically at a specific pressure and rollers’ rotation speed to ensure that the material is processed properly by the suitable shear force.

Roller Cleaning

The rollers of three roll mill should be cleaned regularly to ensure that the processed material is not contaminated with dirt or other debris. The rollers should also be checked for wear and tear to ensure that they are in a good working condition.
