Ralph Hardgrove, a Babcock & Wilcox retiree who joined Stock Equipment Company in 1961 (at 70 years of age), led the feeder's development into general industry acceptance by the mid-1960s, when most large coal-fired boilers included gravimetric feed systems in their design.
Is a rugged gravimetric auger feeder. The unit accurately feeds free flowing color pellets and additives at the throat of extrusion, blow molding and injection molding machines.The system incorporates a special algorithm that filters out vibrations
The primary application of Gravimetric coal feeder is for feeding coal to boilers. However, it is used for any solid fuel feeding to boilers. No pressure, NFPA 85 conditions or even higher pressure inside the coal feeder chamber can be variants in the design of feeders.
Oct 01, 2003· A gravimetric feeder, being a belt feeder device, weighing the coal actually passing over the belt, will react to any reduced feed out of the bunker. The feeders must preserve the entire downward force of coal from the bunker and redirect it in the direction of flow.
