What are Coal feeders? Principle, components.
Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the Volumetric feeders supply a certain volume of material per unit of time. Known volume units of a particular material are used for the volumetric measurement and the material Volumetric Feeder Schenck Process

Volumetric feeders supply a certain volume of material per unit of time. Known volume units of a particular material are used for the volumetric measurement and the material is transferred to a mass-based discharge using scanned calibration. Feeding is changed by adapting the auger speed. Unlike gravimetric feeding, volumetric feeding does notFeeders are auxiliary equipment that dispense a measured amount of an ingredient—a resin, a colorant, or an additive—into resin entering a processing machine.

ing the coal is not desired. Stock volumetric feeders are designed to reliably and safely deliver coal to the boiler and are built in the same tradition as the Stock gravimetric feeder. They are both built to deliver many years of dependable service. This tradition is demonstrated by the thousands of Stock feeders installed worldwide.Variable-speed volumetric feeders convey the coal to the pulverised-fuel mills, where it sis ground to a find powder by hollow-core steel balls running in a circular track. The pulverised coal is then dried and transported to the boiler burners by a stream of hot air, ignited and blown into the furnace, where it burns at a temperature of about 1 275°C.Kriel Power Station Eskom Heritage

DEA Weighbelt feeders are offered in 12” and 24” belt widths with easy belt detensioning and removal, BIC (belt weight influence compensation), accuracies of ± 0.25% to 1% of set rate sigma, and feed rate capabilities up to 1,680 cubic feet per hour. Excellent for weighing and feeding easily damaged materials.A gravimetric feeder, also know as a loss-in-weight feeder, is a self-calibrating dosing system that doses based on weight in speed. A volumetric feeder, on the other hand, does this based on volume in speed. In gravimetric dosing, the weight of the dosed additive is measured using a load cell that is the foundation of the entire system.Gravimetric feeder versus volumetric feeder Movacolor
