Melt-mixing by novel pitched-tip kneading disks in a co-rotating twin-screw extruder

Simulation of Distributive and Dispersive Mixing in a Co-rotating Twin-screw Extruder

Simulation results for mixing of two different polymers in a co-rotating twin-screw extruder are presented. Velocity distribution predicted by a threedimensional simulation of the flow is used to predict the change in the spatial distribution of initially segregated particles as well as the reduction in radius due to erosion. The predicted particle distribution is used to estimate the increase ...

Modeling of Transport Phenomena and Melting Kinetics of Starch in a Co-Rotating Twin-Screw Extruder

A mathematical model was developed to simulate fluid flow, heat transfer, and melting kinetics of starch in a co-rotating intermeshing twin-screw extruder (TSE). The partial differential equations governing the transport phenomena of the biomaterial in the extruder were solved by a finite element scheme. For validating the model, the predicted product pressure, bulk temperature at the entrance ...

evolution of co-continuous morphology along the screw length in a co-rotating twin-screw extruder and its effect on impact strength of compatibilized pa6/abs blend

an ultra-glide twin screw extruder is employed to allow the quick and easy removal of the screws from the fixed processing section within few seconds, probing the current degree of the melting state, the dispersive anddistributive processing steps and finally the level of morphology development along extruder screws. for morphological studies the molten samples, collected from different points ...

Continuous Granulation with a Twin-Screw Extruder

Influence of initial conditions on distributive mixing in a twin flight single screw extruder

Passive advection of light particles carried by a high viscosity fluid in polymer processing equipment exhibits complex behavior due in part to the non-linearity of the equation of motion. The particles motion also exhibits sensitivity to the initial positions. A fundamental understanding of the influence of initial positions of particles on the quality and rate of distributive mixing is essent...
