For all Makes & Models of Coal Feeders * Improve plant heat rate * Account for fuel use Volumetric operation of a coal feeder has served the industry for many years. In a volumetric system the flow of material is controlled by the boiler demand system, but the actual amount fed is estimated and the accuracy can vary greatly.

: Screw feed | Weighing Systems The product is conveyed to the weighing container by the action of the screws (Archimedean screws), which exert an adequate amount of thrust. As a result, the screw-feed system is used for products that are not very free-flowing. This feeding mechanism is also ideal for very powdery and fluidized products, since the screws are contained in a fully enclosed ...
