The higher experimental flo loads on the feeders are due to the fact that the measured values of wall pres sures towards the vicinity of the outlet of the hopper diverge from the radial stress field theory of Jenike. On the basis of the above measurements, the values of Kand n are com puted and the bounds for initial filling are suggested. The flow loads are based on the major consolidating stress u1, which compares satisfactorily with the measured values. Finally, methods to control overloading of the feeders are discussed.
