remarks. He adds that the ActiFlow scanning system is accurate 99% of the time in matching dispersion frequencies to additives. ActiFlow uses two controls for operation. One
monitors the feeder and the other activates the unit. Prior to processing, fl ow-rate information is entered into the control. If material in the hopper bridges and fl ow rate drops, this will be detected from data transmitted by the hopper’s gravimetric load cell and feeder control. This in turn will activate the unit, causing it to send vibrations at the correct frequency and amplitude through the feeder wall to disperse clogged particles. Gomez says ActiFlow may only operate for minutes
during processing. For most of a run it “idles,” awaiting activation if the fl ow rate drops. The system cost, he adds, is comparable to that of a conventional vertical agitator.
Another high-tech gravimetric feeding and blending
system is the MaxiBatch line from Maguire. The systems have been available for a while, but the company continues to fi ne-tune the design based on a growing body of materials behaviour to increase
precision in the machines’ specialty – metering and mixing hard-to-handle powders. Pat Smith, vice president of sales and marketing, says that the initial MaxiBatch was developed for wood composites, compounds whose key ingredient, wood fl our, is among the most diffi cult materials to feed and blend.
