Custom CF-75L Production Internal Mixer For Rubber
Product brief introduction
The 75L internal mixer is designed for efficiently mixing, kneading, and dispersing a variety of chemical materials such as EVA, rubber, synthetic rubber, and hot melt adhesives. It serves as an essential tool for developing experimental formulations that can be seamlessly transitioned to production lines. Built with durability and wear resistance in mind, the mixer ensures uniform blending and consistent modification of material properties, delivering optimal and repeatable mixing results.

Working Principle of Internal Mixer
Inside the mixing chamber, the two rotors rotate relative to each other at a defined speed ratio, drawing material in through the feed port and guiding it into the nip area between the rotors. There, the material is subjected to intense squeezing and shearing forces. As it passes through the rotor gap, it strikes the sharp "W"-shaped edge of the mixing chamber, causing it to split into two streams. These streams flow along the clearances between the front and rear chamber walls and the rotors, eventually cycling back to the top of the rotor. Within the sealed mixing chamber, the materials are thoroughly sheared and blended under controlled pressure and temperature conditions. This process ensures complete dispersion and plasticization of the formulation ingredients, maximizing the performance and consistency of the compound.
Product Superiority
1.Using elliptic shear rotor,the surface of the rotor is coated by wear-resistant surfacing hard alloy,chromate plated for the inside of the mixer chamber surface,abrasion resistant and corrosion resistance,and increase the useful life.
2.Adopted circulation channel structure to achieve the heat conduction medium circulation for the rotor,the mixer chamber and the top peg.According to different requirements of production process,via steam,oil,electric heater or cooling water to cooling or heating.
3.Advance sealing system.
4.The top peg put pressure to the material by cylinder,forced to knead the material evenly to increase productivity.The electric controlling system is adopted the famous brand in China,controlled by manual or automatic,easy to shift and operate reliably.
Technical advantages
A. Changfeng's anti-leakage powder device adopts mechanical shaft seal tightening technology and uses a self-lubricating seal ring to keep the seal ring in a compressed and sealed state during the mixing process. The self-lubricating seal ring further reduces the wear of the mixing system and can more effectively reduce the noise such as whistling caused by leakage and poor sealing.
B. The interior of the mixing chamber adopts a complex tube belt design with good heat exchange and precise temperature control. The rotor adopts water cooling to effectively prevent sticky materials, control temperature accurately, and make the material dispersed more evenly.
After-sales Service
