Stock® Feeder System Users Training. Valuable Training for Stock Equipment Feeder Users. Stock Equipment Company provides an on-site, training session for feeder system owners. Training details the importance of accuracy, maintenance, inspection and parts as well as a forum to discuss feeder issues. of STOCK® Gravimetric Feeders The feeder was typically located immediately beneath the coal bunker and immediately over one of the pulveriz-ers. Coal would pass down into the feeder and onto the horizontal transfer belt within the feeder body. As the coal proceeded from the inlet and toward the discharge, it passed content.powermatic.com Q Manual or Power operation Q The Gravimetric Feeder can be adapted to meet these dimensional constraints by applying the REDLER knowledge of conveying coal with a chain into a STOCK Gravimetric Feeder giving a most suitable and practical design of feeder to deal with short centreline dimensions from inlet to outlet. The STOCK® gravimetric coal feeder weighs material on a length of belt between two fixed rollers (span) precisely located in the feeder body. A third roller, located midway in the span and supported at each end by precision load cells, supports half the weight on the span. This manual has been prepared for the owner and operators of a Powermatic PF3-EZ Stock Feeder. Its purpose, aside from machine operation, is to promote safety using accepted operating and maintenance procedures. To obtain maximum life and efficiency from your stock feeder and to aid in using it safely, 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.
