Atlanta-based Process Control Corp. has incorporated its PF Series powder feeder into its line of Guardian gravimetric blenders.
The powder feeder is an auger type, which Process Control said is ideal for feeding nonflowable powder materials such as talc and blowing agents. The feeder allows processors to meter and blend nonflowable materials accurately with standard pellets and regrind at an economical price, the company said.
PF feeders have two drive systems. The first meters the powder into the weigh hopper. The second agitates the powder above the feed screw, preventing bridging and rat-holing in the hopper.
