The Basic Structure of Single screw Extruder (9)
Heating and cooling system
In order to make plastics processing technology in the specific temperature,generallyextruders are equipped with heating and cooling system device, as well as measurement, temperature control instrumentation.
(1) Extruder heating
Currently, there are some heating methods of single screw extruder, containing hot body heating, resistance heating and electric induction heating.Due to a longer barrel extruder, extrusion process on the barrel temperature in the axis direction has certain requirements. According to the size of screw diameter and aspect ratio, barrel would be divided into several sections to heat. And the head of single screw extruder could set the heating section, depending on their type and size of the nose.
(2) the cooling extruder
Cooling process requirements is a significant part to ensure plastic out of single screw extruder stable, and it closely linked and inseparable with heating system.
