What Is The Working Process of The Kneader?

One of the symbols of the development of internal kneaders is the high-speed, high-pressure, and high-efficiency machines. Generally, low-speed internal kneaders are referred to as those with a rotor speed of 20rpm, those with a speed of 30-40rpm are referred to as medium speed internal kneaders, and those above 60rpm are referred to as high-speed internal kneaders.

In recent years, there have been internal kneaders with speeds up to 80rpm or even higher, as well as dual speed, three speed, and variable speed internal kneaders with extensive adaptability and processing methods to processes and efficiency, as well as internal kneaders with adjustable rotor speed ratios. Its operating time has been greatly shortened, from 8-15 minutes for slow machines in the past to 1.5-3.5 minutes, and some even reach 1-1.5 minutes (including the process of using internal mixing and supplementary mixing methods).

The structure of the kneader is also constantly evolving. The working process of the internal kneader and the mechanization and automation level of the entire unit are also constantly improving, using program control. Nowadays, large imported machines are all controlled by computers. In short, this development is greatly strengthening the mixing process, improving machine efficiency, reducing physical labor, and improving the working environment.

The internal kneader has shown a series of advantages over the open kneader during the mixing process, such as short mixing time, high production efficiency, easy operation, good ability to overcome dust flying, reduce loss of admixtures, improve working conditions, and reduce labor intensity. Due to its development largely relying on experience, there was a belief in the early stages of development that the efficiency of plasticizing was low and it could not be used for plasticizing, but it has been denied by production practice.

Therefore, the emergence of the internal kneader is an important achievement of rubber mixing machinery, and it still remains a typical equipment in plastic and mixing, and is constantly developing and improving. According to foreign data statistics, 88% of rubber materials in the rubber industry are manufactured by internal kneaders, and internal kneaders are also widely used in the plastic and resin industries.

In this intense mixing process, of course, it will bring many new problems. Therefore, for mechanical research and design, from the kneading system, cooling system, sealing system, feeding and pressing system, unloading system, transmission system, control system, main components, materials to various parameter technical decisions and theories of the machine, corresponding development is needed to make the machine perform well and provide possible adaptability and adjustability for the production process.
