It is mainly used for plastic refining and mixing of rubber, and also for mixing of plastic, asphalt material, linoleum material and synthetic resin material. It is one of the main rubber refining equipment in rubber factories. Since the seventies, foreign countries in the rubber refining process and equipment, although the development of faster, such as the use of screw extruders instead of compacting machines and open refining machines for plasticizing and mixing, but still can not replace the compacting machine. The refining equipment in the new modern factories is still mainly based on the dense refiner, and the mixing method still uses the two-stage mixing method.
Classification:
(1) According to the shape of the rotor cross-section: oval rotor refiner, cylindrical rotor refiner, triangular rotor refiner
(2) According to the working principle: tangential rotor refiner, mesh type rotor refiner
(3) According to the rotor speed size and change into: low speed, medium speed, high speed and single speed, double speed, variable speed refiner
(4) According to the relative rotor speed: asynchronous and synchronous rotor refiner
(5) According to the structure of the mixing chamber: ordinary type and flip type compactor
(6) According to the relative gap between the rotor is divided into: fixed gap and adjustable gap refiner
