Three Roll Mill
1. Working Principles:
The three rollers, with parallel arrangement, rotate at different velocity to queeze, rub, shear and grind the materials.
The three roll mill is mainly used to grind all kinds of paints, printing ink, ink, paint pigments, paints, food, chocolate, cosmetics, medicine, and other paste materials (not including those mighe cause the corrosion of the rollers). In recent years, with the development of the cable materials, human leather plastics, soaps, and lead-producing areas, therefore the device has become the major equipment for grinding these materials.
The three rollers are made of the cold hard alloy material and grinded on the special convex abrasive machine, so that the effective working surface of rollers are slightly convex.
Therefore, because the rollers expand with heat and contract with cold, in the process of grinding the machine has automatic compensation to extend the service life, as well as increases the grinding efficiency and fineness.
In accordance with the original fineness, hardness, and toughness, materials can be grinded once, twice or more times, and ultimately to achieve the required fineness (generally about 3-18 microns, determined by the fineness board).
