Compounding: Randcastle compounders use our exclusive, patent pending, Recirculator mixing elements for state of the art mixing.  The Recirculator creates multiple elongation---dispersive---flow fields.  These flow fields break agglomerates and are a primary melting mechanism.  Within the Recirculator, some flow is directed upstream!  The upstream flow then folds into the downstream flow for recirculatory flow.  Up to four Recirculators are available in a single 50/1 screw.  Examples of use:
