PE 300 plastic recycling and regranulation line was built in China in
2011 by Zhangjiagang Wuhe Machinery Co. LTD. The extruder for plastics
used in the processing and manufacturing of various types of materials
can produce up to 300 kg of parts in one hour of operation. The
complete PE and PP plastic extrusion line includes a compactor, screw,
cylinder, conveying system, heating system and temperature control
panel.
Material production begins by heating the plastic to a maximum
temperature of 300°C in the 11 heating zones of the PE 300
granulating line, controlled by thermoregulators. The extruder then
presses the material further through a 100 mm diameter screw located
in a cylinder with abrasion and rust protection. At the end of the
process, the machine head moulds the plastic to give it the right
properties and shape.
The PE 300 extruder is equipped with thermoregulators with a digital
display to control the current temperature of the cylinder and a
special device to protect the extruder from overvoltage.
