The machine is mainly composed of barrel, rotor, unloading device and other parts. The mixing chamber of the equipment barrel is two interconnected holes with a rectangular cross-section. The material is sheared, crushed, kneaded and mixed by the rotor in the mixing chamber. The barrel also has cooling water holes and an electric heater to heat and cool the materials according to process needs. The rotor structure can be divided into a feeding section, a mixing section and a discharging section according to its functions.
The feeding section of the rotor is like a pair of non-meshing twin screws. The surface is composed of rectangular threads to transport the materials added by the metering feeder to the mixing section. The mixing section of the rotor is like a pair of internal mixer rotors. Its surface has two pairs of spiral edges with opposite rotation directions and different angles. The spiral edge connected to the feed section transports the material forward. The spiral edge connected to the discharge section transports the material in the opposite direction. The material is compressed, melted, sheared, stretched and finally mixed and plasticized by the rotor. The discharge section is an oval-shaped material where the materials are discharged from the barrel through the discharge port. The discharge device is composed of a discharge door and an adjustment device. By adjusting the discharge adjustment device, the opening degree of the discharge door can be controlled to control the residence time of the material in the mixing chamber.
