Analysis of the working principle of internal mixer
Internal mixer is a mechanical equipment with high strength and mixed density, mainly used for the processing of polymer polymer materials such as rubber and plastics. It mixes different ingredients of raw materials evenly through physical effects such as high temperature, high pressure, and shear force, and shapes the desired product shape. The working principle of an internal mixer can be divided into the following steps.
1、 Structure of internal mixer
The internal mixer mainly consists of a mixing chamber, upper cover, lower cover, feeding port, discharge port, rotary valve, hydraulic system, control system, etc. Among them, the mixing chamber is the core part of the internal mixer, made of high-temperature and high-pressure materials.
2、 The workflow of the internal mixer
Feeding: Put the raw materials that need to be mixed into the mixing chamber.
Melting: Melting and mixing of raw materials through high temperature and shear force of rotating blades.
Compression: The material in the mixing chamber is compressed into a tight state through the pressure of the hydraulic system.
Exhaust: Discharge excess gas from the mixing chamber.
Discharging: Open the mixing chamber through a rotary valve to discharge the mixed material.
3、 Working principle of internal mixer
Mixing: In the internal mixer, the raw materials are stirred evenly through high temperature and the shear force of the rotating blade.
Melting: Under the action of high temperature and pressure, the polymer materials in the raw material gradually melt, forming a uniform mixture.
Compression: By using the pressure of the hydraulic system, the materials in the mixing chamber are compressed into a tight state, further improving the mixing effect.
Exhaust: During the mixing process, excess gas will remain in the mixing chamber and needs to be discharged through the exhaust port to ensure the quality of the mixture.
Discharging: Open the mixing chamber through a rotary valve to discharge the mixed material.
4、 Advantages of internal mixer
High efficiency: The internal mixer can quickly and efficiently mix different raw materials evenly.
High quality: The internal mixer can process high-quality products.
High yield: The processing speed of the internal mixer is fast and the output is high.
High reliability: The internal mixer is made of high-strength materials, which has high reliability.
5、 Application scenarios of internal mixer
The internal mixer is mainly used for the processing of polymer materials such as rubber and plastic, such as tires, shoe soles, pipes, plates, and other products.
Internal mixer is a mechanical equipment with high strength and mixed density, which mixes different raw materials evenly and shapes the desired product shape through physical effects such as high temperature, high pressure, and shear force. It has the advantages of high efficiency, high quality, high yield, and high reliability, and is widely used in the processing of polymer polymer materials such as rubber and plastics.
