The CF-25L internal mixer is engineered for mixing, kneading, and dispersing various chemical raw materials including EVA, rubber, synthetic rubber, and hot melt adhesive. This robust equipment ensures uniform material mixing and achieves optimal physical property changes, making it ideal for transitioning experimental ratio formulas to full production lines.

The internal mixer features two rotors that rotate relative to each other at a specific speed ratio. Material is fed through the inlet and drawn into the roller gap where it undergoes intense squeezing and shearing action. After passing through the gap, the material impacts the sharp edge of the "W"-shaped mixing chamber and divides into two streams, flowing along the gaps between the front/rear chamber walls and rotors before returning to the rotor top. This continuous cycle creates strong shearing and mixing under controlled pressure and temperature conditions, ensuring complete dispersion and plasticization of formula materials for optimal performance.

A. Advanced Anti-Leakage System: Changfeng's mechanical shaft seal tightening technology utilizes self-lubricating seal rings that maintain compression during mixing, reducing system wear and eliminating noise issues from leakage.

B. Precision Temperature Control: Complex tube belt design in the mixing chamber ensures excellent heat exchange and precise temperature regulation. Water-cooled rotors prevent material sticking and promote uniform dispersion.

Non-consumable parts are guaranteed for one year during normal operation. We provide on-site installation guidance and long-term technical support to ensure optimal performance.
