Three roll mill is widely used in milling paste material including paint, inks, China ink, pigment, coatings, food, cosmetic and so on.(Not applicable for roller corrosion material). It is also used in cable material, artificial plastics, soap and pencil core material. It become the key equipment for those industry.
The roller material is made up of cold hard alloy centrigugal casting. The cold hard alloy thickness is between 15 and 25mm, hardness is between HS 68-75. The roller is grinding on convex grinder, the effective working surface is a bit convex. During the milling process, because of hard roller and thermal expansion and contraction, it can compensate automatically so as to improve machine life, also improve the material accuracy and efficiency. For normal material, as its original finess and hardness, it can be milled once, twice and even more times till it reaches requirement(Normally between 3 and 18 micron as gauge measured)
