Lab Two Roll Mill
A Basic Mill for Mixing Rubber and Plastic
We are Yangzhou Zhengyi, a factory with 17 years of experience. Our lab two roll mill helps you mix, plasticate, and warm rubber and plastic. You use this product in factories and labs. We have two models. The XK-160 uses water cooling. The SK-160 uses electric heating. Both are 6inch roll mills. They are common tools for rubber and plastic work.

Same Base Specs for Both Models
Both models have a roll diameter of 160mm and a roll face width of 320mm. The front and back roll speed ratio is 1:1.35. The front roll linear speed is 9.04m/min (17.85 rpm). The back roll linear speed is 12m/min (24 rpm). The roll gap is 0-5mm. The feed amount per batch is 1-2kg. Roll hardness is HRC65. The gap adjustment uses a ratchet. Seals are skeleton oil seals, so they are clean. Both come with a nylon material stopper and an emergency brake. The gearbox is hard-faced with low noise. Bearings run smooth and last long. This lab two roll mill gives you good control.

Differences Between the Two
The XK-160 (water cooling) has a 5.5KW motor. The cooling is water. Its size is 1300×900×1300mm. Weight is about 800kg. The SK-160 (electric heating) has a 4KW motor and 3.6KW heating power. The heating temperature goes from room temperature up to 250℃. Its size is also 1300×900×1300mm, but weight is about 700kg. Both use a Y132M2-4 motor, a gearbox, and chain sprockets. So you choose the product based on whether you need heating or cooling.
