Zusammenfassung:Solids conveying is the least understood process for single-screw extruders. This lack of understanding was caused by the unavailability of solids conveying rate data. A new device has been developed to measure solids conveying rates as a function of barrel and screw temperatures, screw speed, and discharge pressure. These data along with friction and bulk density data will be used to determine the accuracy of several solids conveying models.
