gravimetric coal feeder theory

  • Basics of Gravimetric and Volumetric Feeding : Plastics

    A lossinweight feeder is a gravimetric feeder that directly measures the material's weight to achieve and maintain a predetermined feed rate measured in units of weight per time. The following section ( The Gravimetric Feeding Triangle ) introduces the three main challenges faced by any gravimetric feeder: material handling, weighing and control.
