[0003] The rubber internal mixer is internally provided with a rotating rotor, and the rotor is provided with helical blades. Through high-speed rotation, the rubber is subjected to strong stirring and shearing. In the working process, the rubber is subjected to strong stirring and shearing by the rotor blades, so that the molecular chains of the rubber are broken and the plasticity of the rubber is increased. At the same time, additives such as carbon black and sulfur can be uniformly dispersed in the rubber to form uniform rubber. A heating device is arranged in the mixing chamber to adjust the temperature according to the process requirements and ensure the quality of the rubber.
