Introduction to Extrusion - Dynisco
www.dynisco.comWith a single screw extruder the hopper is filled and the screw takes in the material at the rate it wants. Such a scheme, called flood feeding, is often not possible with twin screw machines. This is because the very positive feeding characteristics of twin screw machines may result in very high forces being generated.
