Kneading machine used in rubber, plastic and other material plastication. mixing and blending. The plastic material in a sealed, pressurized and  temperature under controlled conditions of milling or mixing, has the characteristics of high production efficiency, excellent and stable quality,  parameters of spiral angle and the prisms overlap length of the rotor design of edge is reasonable, can make the material dispersion. and material contact  parts surface by grinding of hard chromium plating after polishing, the rotor Lengfeng push welding wear-resistant hard alloy. wear and corrosion. and aterial contact parts are jacketed structure, can be water, steam, oil medium, has good cooling or heating effect, adapt to all kinds of rubber. refining  the process requirements.
