  • Top Ten Frequently on Feeder Accuracy - Pipe and Profile

    Since, as mentioned above, volumetric feeders are open-loop devices from the viewpoint of discharge rate, headload variations and material buildup on the flights of a feed screw change the volume-per-revolution relationship, throwing off calibration without any outward sign. Gravimetric feeders automatically detect and adjust to these conditions.

  • Gravimetric and volumetric feeders: What are they? And ...

    Feeders are auxiliary equipment that dispense a measured amount of an ingredient—a resin, a colorant, or an additive—into resin entering a processing machine. The term “volumetric” refers to one way that a feeder measures and dispenses an ingredient. The other way is called “gravimetric.” Let’s briefly look at both: Volumetric ...
