Theory and Designing Method of Screw Extruder for Ptastic Extrusion

Twin-Screw Extruder and Effective Parameters on the HDPE Extrusion Process

In the process of polyethylene extrusion polymer material similar to powder or granule is under compression, melting and transmission operation and on base of special form, extrudate has been produced. Twin-screw extruders are applicable in industries because of their high capacity. The powder mixing with chemical additives and melting with thermal and mechanical energy in three zones (feed, co...

Continuous Granulation with a Twin-Screw Extruder

Sequential calculation of torque in procedure of twin screw extrusion

The drug making resreach has accentuated on extrusion technology for a long time. The advance of drug bioavailibility, bead manufacturing and granulation is assured by extrusion procedures. There are also diverse effects in resereches with respect to the use of process understanging as a tool in quality management. Many initiatives of FDA such as PAT and QBD are getting accepted. In this survey...

Wet granulation in a twin-screw extruder: implications of screw design.

Wet granulation in twin-screw extrusion machinery is an attractive technology for the continuous processing of pharmaceuticals. The performance of this machinery is integrally tied to its screw design yet little fundamental knowledge exists in this emerging field for granulation to intelligently create, troubleshoot, and scale-up such processes. This study endeavored to systematically examine t...

Twin Screw Extrusion of Aluminized Thermobaric Explosives

The manufacturing of advanced explosives containing large amounts of metal powders to improve performance, such as PAX-3, have proven difficult to transition into production. Current manufacturing processes have had low yield which results in a high cost per unit and questionable product uniformity. Over the past year the Twin Screw Extruder (TSE) Team has been investigating the use of a TSE ma...
