Introduction of rubber kneader

Rubber kneader is used for rubber, the ideal equipment for kneading, mixing, vulcanization, and polymerization of high viscosity, elastic and plastic materials. The next step will introduce you the rubber kneader.

What is the history of the principle of the rubber kneader?

The kneader was developed by Heinz Ries, and the technology became quite popular as soon as it appeared in the processing industry. In 1966, Heinz stated that " high concentrations of material are more efficient an economical in operation than low concentrations". According to Heinz,handling highly concentrated material means that there are fewer or no solvents, which maximizes the process yield per unit volume. Handling highly concentrated material is inherently complex and challenging, and new technology need to be developed to better handle highly concentrated materials. So, he began to develop reliable process technology that could handle phase changes in highly concentrated materials, the so-called"dry process", or kneader, which evolved into the rubber kneader.

What are the structural characteristics of the rubber kneader?

1. Rubber kneader generally adopts the shole machine through the chassis, easy to install.

2. Rubber kneader adopts helical gears or hardened gear reducer to make and host smooth transmission, low noise, long life.

3.Stirring paddle and mixing cylinder wall, using SUS304 stainless steel or SUS316L stainless steel material, to ensure the purity of the product.

4. Rubber kneader seal structure is advanced, of good sealing effect. The uqique desigh of the vacuum box balance structure ensures that no black material will be ground out.

5. Rubber kneader integrated electrical control ( host operation, hydraulic flip cylinder, hydraulic opening cover, and constant temperature control) and temperature control and temperature display, easy to operate and process control.

What is the working principle of a rubber kneader ?

A rubber kneader is a pair of sigma paddles that work together and rotate to produce a strong shearing effect, thus making the semi-dry or rubber -like viscous plastic material react quickly to obtain a uniform mixing and stirring. Rubber kneader is mainly composed of five major parts, such as mixing part, machine base part, hydraulic system, transmission system, and electric control system, in addition to the internal mixer. The hydraulic system of the rubber kneader is operated by a hydraulic station to manipulate the large oil cylinder to complete the opening and closing function, and the hydraulic system is operated by a hydraulic station to manipulate the oil cylinder to complete the functions of turing the cylinder and opening the cover, tec. The detailed parameters can be arbitrarily selected and required by the user, and the operation is convenient and reliable. The transmission system consists of electric motors, reducers, and gears, according to the model of the kneader supporting the motor. The transmission part of the rubber kneader is synchoronized by the motor speed, and after the flexible coupling to the reducer, the output device drives the fast pulp to the specified speed, which can also be regulated by the frequency converter.The internal mixer of the rubber kneader is a very important part and an essential part of the rubber kneader to be able to operate properly.The rubber kneader has two sigma-type paddles. The speed of the two paddles is different and can be set at different speeds depending on the process, the most common speed being 42/28 revolutions per minute.
