Product Description
Accurate Control Banbury Machine Rubber Mixer, Rubber Kneading Machine 25L
Custom High-efficiency Production Banbury Kneader Internal Mixer
The 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 production lines.

Working Principle
The internal mixer features two rotors that rotate relative to each other at specific speed ratios. Material is fed through the inlet and carried into the roller gap where it undergoes compression and shearing. After passing through the gap, the material impacts the sharp edge of the "W" shaped mixing chamber, dividing into two streams that flow along the front and rear chamber walls before returning to the rotor top. This closed-system process ensures strong shearing and mixing under controlled pressure and temperature conditions, resulting in optimal dispersion and plasticization of formula materials.
Mixing System Design
The mixing chamber features a "W" shape with an "M" shaped lower pressure cover, creating a fully enclosed mixing space. The prismatic spiral stirring blades eliminate dead angles, ensuring complete material shearing and dispersion. Constructed with hollow blades made from high-carbon steel, the contact surfaces undergo quenching, tempering, and 72-hour deep nitriding heat treatment followed by hard chrome plating. This advanced construction provides exceptional hardness, wear resistance, corrosion resistance, and prevents material sticking for extended service life.
Product Advantages
  • Elliptic shear rotor design with wear-resistant surfacing hard alloy coating and chromate-plated mixing chamber interior for enhanced abrasion and corrosion resistance
  • Circulation channel structure enables heat conduction medium circulation for rotors, mixing chamber, and top peg, supporting steam, oil, electric heating, or water cooling
  • Advanced sealing system for reliable operation
  • Cylinder-powered top peg applies pressure to materials, ensuring uniform kneading and increased productivity
  • Premium Chinese brand electrical control system with manual/automatic operation modes for easy switching and reliable performance
Technical Superiority
Leakage Prevention: Changfeng's anti-leakage powder device utilizes mechanical shaft seal tightening technology with self-lubricating seal rings that maintain compression during mixing, reducing wear and minimizing noise from leakage issues.
Temperature Control: The mixing chamber interior features a complex tube belt design for excellent heat exchange and precise temperature regulation. Water-cooled rotors prevent material sticking and ensure uniform dispersion.
After-sales Service & Components
Non-consumable parts are guaranteed for one year during normal operation. We provide on-site installation guidance and long-term technical support. Electrical components and motors are sourced from premium Taiwanese and international brands.
