Single Screw Extruder Characteristics on Friction and Heat Generated with the Barrel Carved Spiral Groove
To make single-screw extruder with extrusion pressure enough, through theory of friction-induced extrusion pressure，which has been generally accepted in the industry. The barrel designed modular structure, in the before barrel carved groove, to add the friction coefficient between barrel and solid material. It form extrusion pressure In this section by exponential increase. This papers analyze that use of spiral groove instead of linear grooves can effectively reduce the frictional heat generation.
