A new gravimetric feeder design from CRG Logics, Inc., Green Bay, Wis., is said to cut cleanout times to seconds. The new feeder appears on the CRG Simplicity Series continuous gravimetric blender, which is aimed at compounding or extrusion of resin blends. Its variable-speed vibratory feeders have a positive material shutoff on the hopper, allowing quick removal of the feeder for draining and cleanout. In addition, new options on the Simplicity blender include integral vacuum-system control, a purge hopper for quick, easy extruder purging, and PC-based software to track material usage and inventories on multiple blenders.
