Custom 55L Production Internal Mixer For Rubber
Product brief introduction
The 55L 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
The two rotors in the mixing chamber rotate relative to each other
under a certain speed ratio, clamping the material from the feeding
port and bringing it into the roller gap to be squeezed and sheared
by the rotors. After passing through the roller gap, it hits the
sharp edge of the mixing chamber "W" and is divided into two parts,
respectively along the gap between the front and rear chamber walls
and the rotors and then returns to the top of the rotor. In the
closed mixing chamber, the material is strongly sheared and mixed
under certain pressure and temperature conditions, so that the
formula materials are fully dispersed and plasticized, so that the
formula can play the best effect.
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
During normal use, non-consumable parts are guaranteed for one
year. We provide on-site installation guidance and long-term
technical support.
Note: Electrical components and motors are imported from Taiwan and
foreign brands.
