  • Should coal-fired power plants use gravimetric feeders?

    With coal, this approach is problematic. According to Schenck, coal density changes with size, moisture and a variety of other factors. Therefore, even if an operation were processing coal of equal dimensions, each piece may have a different density. In light of this reality, gravimetric weigh feeders are the better option. These instruments

  • 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.
