Introduction to energy saving details of extruder

The energy saving of the extruder can be divided into two parts: one is the power part and the other is the heating part.
Energy saving in the power part: Frequency converters are mostly used. 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 actually only need 30Hz in production, and the excess energy consumption is wasted. Wasted, the inverter changes the power output of the motor to achieve energy saving.
Energy saving in the heating part: Most of the energy saving in the heating part is the use of electromagnetic heaters. The energy saving rate is about 30% to 70% of that of the old-fashioned resistance coil.
work process
The plastic material enters the extruder from the hopper, and is transported forward by the rotation of the screw. During the forward movement, the material receives the heating of the barrel, the shearing and compression brought by the screw, causing the material to melt. , thus realizing the change between the three states of glassy state, highly elastic state and viscous flow state.
When pressurized, the material in a viscous flow state passes through a die with a certain shape, and then becomes a continuum with a cross-section similar to that of the die according to the die. Then it is cooled and shaped to form a glassy state, thereby obtaining the required processed parts.
