The good operation of the internal mixer is inseparable from the performance of each component. Therefore, the role of each component is very critical.
　　Mixing part: The mixing part mainly consists of a rotor, a mixing chamber, and a sealing device.
　　 Feeding part: It is mainly composed of the right feeding chamber, the bucket-shaped feeding port and the flap door (feeding door) 11. This part is mainly used for feeding and instant storage.
　　 Material pressing part: It is mainly composed of the upper pin 9 and the cylinder 14 which pushes the upper pin to move up and down. Its main function is to put a certain pressure on the rubber material, accelerate the rubber mixing process, and improve the rubber mixing effect.
　　 Unloading device part: It is mainly composed of the lower top bolt 3 and the lower top bolt locking mechanism 2 installed under the mixing chamber. Its main function is to discharge the rubber material after the rubber mixing is completed, that is, to discharge the material. The lower top bolt can be cooled by cooling water, and the surface of the lower top bolt in contact with the material should be welded with wear-resistant alloy to increase its wear resistance.
　　 Heating and cooling system: mainly composed of pipes and distributors, so that cooling water or steam can be circulated in the cavity of the mixing chamber, rotor and upper and lower top plugs to control the temperature of the rubber compound. The heating and cooling system of the internal mixer imported from abroad is equipped with a temperature control device and adopts constant temperature water for heating and cooling. Function: According to process requirements, control the temperature of the rubber during the mixing process
　　Hydraulic system: It is mainly composed of a double vane oil pump 15, a rotary oil cylinder 17, a reciprocating oil cylinder 16, pipelines and oil tanks. It is the power supply part of the unloading mechanism. Used to control the opening and closing of the lower top bolt and the lower top bolt locking mechanism.
　　 Air pressure system: It is mainly composed of cylinder 14, piston 13, charging valve cylinder, air valve, pipeline and compressed air. It is the power supply part of the feeding and pressing mechanism. It is used to control the lifting, pressurizing and opening and closing of the flap door.
　　Electric control system: It is mainly composed of a control box, an operating machine and various electrical instruments. It is the operation center of the entire machine.
