At NPE2009 in Chicago, TSM Control Systems Inc. showed its technology designed to boost usage of regrind and lower consumption of virgin resin.
The Atlanta-based company said many processors are unable to process higher percentages of regrind because of constraints of their mixing equipment, particularly the inability to get more regrind through the throat of processing equipment.
TSM attacks the problem by cramming material though the throat of the machine, using its patented reverse-flight auger mixing technique.
The method allows companies to process up to 100 percent low-bulk-density flake regrind directly in TSM's new Opti-Mix line of gravimetric blenders, the firm said.
