  • Rotary Gravimetric Coal Feeders

    The coal is extracted out of a coal silo (1), supported by an aeration system (2). The rotor weighfeeder Pfister DRW (4) doses the coal with high precision and the transport air (5) discharges the machine and blows the coal directly to the burner. The high feed accuracy of the rotor weighfeeder ensures a steady air/coal mixture for the burner

  • Which is better: a volumetric or gravimetric weigh belt feeder?

    That means the ongoing weighing and selfchecking of a gravimetric weigh belt solution feeder is a better fit in this case. Alternatively, a coal handling operation may just require a constant flow of coal to be cleaned, meaning a volumetric weigh belt feeder works better for this appliion. Operators also need to consider the difference in ...
