Extruder energy-saving working process

Apr 18, 2018

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 power section: Most inverters are used. The energy-saving mode is to save the remaining energy of the motor. For example, the actual power of the motor is 50Hz, and you actually only need 30Hz in production to produce enough. The extra energy consumption is in vain. Wasted, the frequency converter is to change the power output of the motor to save energy.

Heating part of the energy: Most of the heating part of the energy-saving is the use of electromagnetic heater energy saving, energy-saving rate is about 30% to 70% of the old resistor ring.

work process

The plastic material enters the extruder from the hopper and is conveyed forward by the rotation of the screw. During the forward movement of the material, the material is melted by the heating of the cylinder, shearing and compression by the screw. , thus achieving a change in the three states of glassy, highly elastic and viscous flow states.

In the case of pressurization, the material in the viscous flow state is passed through a die having a certain shape, and then, according to the die, it becomes a continuum whose cross section and the die look are similar. This is followed by cooling to form a glass state, thereby obtaining the desired processed article.
