Accurate Control Banbury Machine Rubber Mixer , Rubber Kneading Machine 25L

Product Specification

Custom High-efficiency 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.

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.

Mixing system

The mixing chamber is "W" shaped, with an "M" shaped lower pressure cover to form a fully enclosed mixing space. The stirring blade adopts a prismatic spiral design without dead angles, so that the material can be sheared and dispersed to meet the physical property requirements. The stirring blade is a hollow structure, and the part in contact with the material is made of high-carbon steel. After quenching and tempering, vacuum 72 hours deep nitriding heat treatment, the surface is plated with hard chrome to increase the hardness, ensuring that the mixing chamber is strong and wear-resistant. Wear-resistant, anti-corrosion, not easy to stick to the material, and long service life.

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.
