The Basic Structure of Single screw Extruder (10)
Shunt Plate and Filters
In the barrel and the die junction of single screw extruder to set diversion board (also known as perforated plate), and filters, whose role is to make material flow from the rotary motion into linear movement, to prevent impurities and non plastics materials, to increase the back pressure, so that products more compact. And shunt plate acts as a supports for filters .But it is usually useless ,when the viscosity of extruded rigid PVC is large, while Unstable.
