Starve Feeding of Co-Rotating Twin Screw Extruders–SPE Carolinas Section 

Overview

Given the array of raw materials often fed into compounding twin screw extruders it's no wonder that the feeders often become problematic.  Join the Carolinas Section for their February meeting and hear Andy Kovats of Brabender discuss how such feeders work, how to specify the correct feeder for your application, and how to configure, program, and troubleshoot it.

Starting with some examples of the materials to be fed into the extruder, Andy will discuss agitation techniques to ensure consistent flow, then move on to screw design for belt or vibratory feeders for volumetric feeding.  Installing such feeders on scales, however, permits Brabender to supply loss-in-weight feeders, including the process by which they are refilled, controlled, and programed.  He will end with a short discussion on liquid feeding using loss-in-weight feeders as well.

Andy Kovats has been involved in the specification, application, and sales of feeding equipment since 1984. Well-known to those of us in extrusion, he is one of the most experienced of Brabender’s technical resources.
