PE PP Pelletizing Production Line

Description

Todys, Let’s introduce the PE PP pelletizing production line for you.

PE PP pelletizing production line is composed of a parallel single or twin-screw extruder and auxiliary machines.

Components of PE PP Pelletizing Production Line

Process setting of PE PP Pelletizing Production Line (From Wiki Article)
Segmentation and Function:
The screw is generally divided into five sections: conveying section, melting section, mixing section, exhaust section, and homogenizing section.
Firstly, conveying section, conveying materials and preventing overflow.
Secondly, the melting section, which fully melts and homogenizes the material through heat transfer and frictional shearing.
Thirdly, the mixing section further refines and evens the size of the material components to form an ideal structure, which has the function of distributive and dispersive mixing.
Andthen, the exhaust section discharges impurities, such as water vapor and low molecular weight substances.
Finally, in the homogenization (metering) section, conveying and pressurizing, a certain pressure is established to make the material at the die mouth have a certain density, and at the same time, it is further mixed, and finally achieves the purpose of smooth extrusion and granulation.
