Energy saving of auxiliary equipment of plastic extruder

Energy saving of extruder can be divided into two parts: one is the power part and the other is the heating part.
Energy saving of power part: Most of them use frequency converters. The energy saving method is to save the residual energy consumption of the motor. For example, the actual power of the motor is 50Hz, but you only need 30Hz in production. The excess energy consumption is wasted. The frequency converter changes the power output of the motor to achieve energy saving.
Energy saving of heating part: Energy saving of heating part mostly uses electromagnetic heaters for energy saving, and the energy saving rate is about 30%~70% of the old resistance coil.
Working process
Plastic material enters the extruder from the hopper and is transported forward under the rotation of the screw. In the process of forward movement, the material is heated by the barrel, sheared and compressed by the screw to melt the material, thus realizing the change between the three states of glass state, high elastic state and viscous flow state.
In the case of pressurization, the material in the viscous flow state passes through a die with a certain shape, and then becomes a continuum with a similar cross-section and die pattern according to the die. It is then cooled and shaped into a glassy state, thus obtaining the desired processed part.
