Which is better: a volumetric or gravimetric weigh belt ...
Sep 10, 2019· Volumetric weigh belt feeders are openloop, setspeed devices, meaning they are dependent on a constant infeed of materials at a regular volume and density to work. This equipment is called open loop because there is no information being communicated between the feeder output and drive control system.
How coal flow is measured in thermal power plants? Quora
Usually the weight of the coal has been measured in Raw Coal Feeder (RC Feeder). The Raw Coal feeders are classified according to the method by which the rate of coal flow is determined.
