Three roll mill (triple roll mill) 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.
The material is fed into gap between feeding roller and middle roller from feeding hopper, to start first squeeze and milling, then transfer into outlet roller for second milling. The material can be collected in outlet blade after second milling to finish the operation process. The material can be mixing and milling between three rollers until reach the fineness. The milling times and fineness are related with material quality and previous process.
improvement type machine manual triple roll mill is equipped with latest overseas chain wheel transmission system, all the gears are dipped inside lubricant which will prolong the machine life to maximum limit, reduce noise and energy consumption. All the sealing parts are imported. The formerly top roller adjustable structure have changed into gear adjusting roller which operate more stably and easily, working longer time. The water temperature indicator can be set in both inlet and outlet to assure stable temperature and good quality. The cooling water cycling system and roller heating system can be available as customer request. The products outlet is made of stainless steel. The outside of machine is coated with anti-dissolvent paint which make machine shining and prevent any possible dissolvent corrosion.
Three roller mill is widely used in milling paste material including paint, inks, pigment, coatings, dye, chocolate, cosmetic, soap, oil, lubrication grease, electronic paste, plant gum… S type Three roll mill is the key equipment for those industry.
The roller material is made up of centrigugal casting anti-wear cold hard alloy steel. The cold hard alloy thickness is 20mm, hardness is between Shore hardness 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)
