Development of a global computer software for modular self-wiping corotating twin screw extruders

An analysis software for intermeshing modular corotating twin screw extrude rs was developed. A global computation model was incorporated in analysis s oftware. The development of the composite model simulation of solids convey ing, melting, and melt flow in a modular corotating twin screw extruder is described. We discuss the applications of simulation which predict axial fi ll factor, pressure, temperature, torque, power consumption, specific energ y consumption, and average residence time. Design analyses for modular coro tating twin screw extruders with multiple ports are presented for the vario us processing conditions. The results are compared for different size of ma chines. These computation results can assist the process-designing engineer in the optimization of an extruder design and operation parameters for var ious usage of machine.
