Plastic extruder bearings play an important role!

The bearing of plastic extruder is used in plastic extruder, so an important part of plastic extruder is the driving mechanism. It controls the rotation speed of the screw, which determines the output of the plastic extruder. The power required is determined by the viscosity (flow resistance) of the polymer. The viscosity of the polymer depends on the temperature and flow rate, and decreases with the increase of temperature and shear force. Plastic extruders are equipped with screens, which can block impurities on the screen. To avoid shutdown, the filter screen shall be able to be replaced automatically. This is very important when processing resins with impurities, such as recycled materials. The screw of extruder is divided into feeding section, plasticizing section and melting section. The temperature is divided into 20, 36, 52, 65, 75, 95, 120 and 135 according to the screw diameter according to the process parameters of plastic particles and the model. After heating, the movement of the screw changes the original state. There are many types, depending on the specific application. The capacity of frequency conversion is directly proportional to the diameter of screw, and then adjusted according to different raw materials.
