BIN HOPPER ENGINEERING AND BULK MATERIALS FLOW: A STATE-OF-THE-ART REPORT ON EMPIRICAL AND THEORETICAL ANALYSES

This Bureau of Mines report is an evaluation of the state of knowledge about gravity flow from bin hoppers the most commonly used method of handling bulk materials where the force of gravity is used. The requirements for flow to be initiated and to continue, formulas developed experimentally or mathematically from various assumptions to describe the materials flow, and the question of whether or not a material will flow over the entire cross sectional area of the bin hopper according to the flow regime developed are the primary areas discussed. The work of A.W. Jenike, whose pioneering investigations raised bin hopper design from the trial and error state, is examined in depth and its limitations and assumptions are pointed out. Bin hopper design depends heavily upon prior experience, and suggestions for further studies of bin hopper flow to include the effects of feeders are made.
