Getting good clean regrind back into the process is necessary for profitability, but painful to do. Old style units beside the press granulators are loud, make fines and “longs” that effect part quality and material transfer, and are energy inefficient. What they do well is take a large slug of runners or parts and are built to take a beating.
The new low speed units make clean regrind, are quiet, and very energy efficient, however they should be paired with a sprue picker or robot to efficiently feed them because they are not as good at eating a slug of runners and parts as the old style units. Utilizing a complete package of a sprue picker, low speed granulator, and blender or proportioning loader will pay back in higher quality regrind and better utilization of your regrind so it doesn’t accumulate in your material inventories.
