75L High Efficiency Banbury Rubber Mixer Machine With Two Rotor Chamber

CFine 75L High Efficiency Falling Type Internal Rubber Mixer

Product brief introduction

Designed for laboratory and small-scale use, the 75L experimental internal mixer can handle a variety of materials such as EVA, rubber, synthetic rubber, and hot melt adhesives. Formulas mixed in this equipment can be transferred directly to industrial production. With its durable, wear-resistant build, the machine provides thorough blending and stable changes in material properties. It is regarded as one of the most effective mixers for teaching, sample making, and limited production runs.

Technical Data

Product Feature

1. Internal rubber mixer,film and wear-proof,suitable for mixing and plasticing raw material like EVA Rubber,Hot melt gule and so on.Nice Homogeneity of raw material can be achieved in company with good physical property change.

2. Rotors and edges are machined in an integral way which results in Strong carrying capacity.

3. All parts contacting with raw material directly are made of superior alloy steel which makes the mixing chamber more wear-proof,stable and anti-corrosion,long service life.

4. New design for leakage-proof of powder,easy to dismantle and replace.

5. Hydraulic way makes raw material to be mixed more efficiently.

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.

Technical advantages

1. CFine's anti-leakage powder device adopts mechanical shaft seal tightening technology and uses self-lubricating seal rings to keep the seal rings in a compressed and sealed state during the mixing process. The self-lubricating seal rings can further reduce the wear of the mixing system and more effectively reduce the noise such as whistling caused by leakage and poor sealing. It can greatly improve the anti-leakage powder function, making cleaning, color change and disassembly simpler and more convenient, and reduce the pollution to the materials.

2. This machine adopts a through-type heating system, which heats faster and transfers temperature more evenly, and the heating efficiency is 50% higher than that of traditional heating plates. It adopts a PLC program control system.

3. The internal structure of the mixing chamber adopts a complex tube-belt design, which has good heat exchange and precise temperature control. The rotor is cooled by water, which effectively prevents sticky materials and controls the temperature precisely, making the materials dispersed more evenly.
