Rubber mixing kneader machine

1. Introduction of Rubber kneader

The internal mixers of this series adopt elliptical tangential rotors. The working surfaces of the rolls are coated on with wearable hard alloy by built-up welding method. The internal surfaces of the mixing chamber and the working surfaces of the pressing ram device are all treated with hard chrome plating, which are durable and corrosion proof and have a longer service life.

The rotors, the mixing chamber and the discharging door are all structured with circulating channels to realize the circulation of heat transmission medium. According to processing requirements, the mixing materials may be heated with hot steam or cooled with cold water.

The rotors are supported by rolling bearings, which are easy to maintain and have a long service life.

The transmission system adopts NGW planetary hardened-gear speed reducer, which has a compacted structure with higher transmission efficiency, lower noise and longer service life.

The pressing ram device is driven by pneumatic cylinder to press onto the mixing materials to force them equally mixed o as to increase productive efficiency.

The feed hopper door is arranged at the back of the machine and the mixing chamber adopts hydraulic driven tilting discharge device. The operation is steady and reliable. It is easy to clean up the chamber and change the color of materials.

Both manual and automatic modes are arranged to operate PLC electric control system. It is easy to exchange the modes and reliable to operate the controller.

2. Features of Rubber Kneader

1.high efficiency. Rubber or plastic material will plasticized or mixed with high productivity in a closed ,pressurized and controlled temperature environment.

2.energy saving. the capacity is 6~8 times compared with open mill under the same condition of power level.

3.eco-friendly.the special dust sealing unit provide reliable sealing

4.durable in use. The banbury rotor adopt 42Crmo material and plated hard chorme made it wear-resisting greatly so does the speed reduce and gearbox;

5.excellent cooling/heating effect .all the parts connect with material adopt jacket structure and can adapt different requirements for the rubber or plastic mixing process.

6.high mixing quality.optimization of the parameters such as the helical angle of rotor wings and the wing overlap length brings about homogenous distribution of the stock.

7.PLC control.
