Custom Capacity Banbury Internal Mixer For Chemical Raw Materials Mixing

Product Specification

Custom Low Price Production Banbury Kneader Internal Mixer

Product brief introduction

25L internal mixer is suitable for mixing, kneading and dispersing various chemical raw materials such as EVA, rubber, synthetic rubber, hot melt adhesive, etc., and then putting the experimental ratio formula into the production line. The equipment is sturdy and wear-resistant, and ensures that the material mixing is uniform and the physical property changes are achieved to achieve the best effect of year-on-year mixing.

High-Efficiency Compounding with the 25L Banbury Internal Mixer

The 25L Banbury Internal Mixer is a cornerstone of modern chemical processing, engineered specifically for the intensive mixing, kneading, and dispersing of high-performance raw materials. This versatile equipment is the industry standard for handling complex substrates, including EVA, natural rubber, synthetic rubber, and high-viscosity hot melt adhesives. By providing a high-torque environment with controlled shear forces, the Banbury Internal Mixer ensures that polymers and additives are homogenized with absolute precision. This makes it an indispensable asset for facilities that need to validate experimental ratio formulas before transitioning to full-scale mass production.

A primary technical advantage for industrial buyers is the machine’s ability to ensure that material mixing is uniform and that physical property changes are consistent throughout the batch. The Banbury Internal Mixer is designed to achieve the "best effect of year-on-year mixing," meaning it delivers repeatable results that allow manufacturers to maintain strict quality control across different production cycles.

Professional buyers choose this 25L model based on several critical performance selling points:

• Exceptional Durability and Wear Resistance: Constructed with reinforced chambers and specialized rotor alloys, the equipment is incredibly sturdy and wear-resistant. This robust build quality is essential for managing the high pressures and abrasive fillers often found in rubber and EVA compounding.

• Seamless Scale-Up Capability: The 25L capacity is perfectly positioned to act as a bridge between the laboratory and the factory floor. It allows R&D teams to refine formulations in a controlled environment, ensuring that the physical properties of the "experimental ratio" will scale accurately to larger production lines.

• Precision Thermal Management: Equipped with advanced heating and cooling systems, the Banbury Internal Mixer prevents the thermal degradation of sensitive elastomers and adhesives, maintaining the chemical integrity of the formula.

• Optimized ROI and Energy Efficiency: By reducing mixing times and improving dispersion quality, this mixer lowers the energy cost per kilogram, providing a superior Return on Investment (ROI) for specialized manufacturing plants.

Technical Data

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.
