Experimental research of product flow in gravity loading hopper

The test object is a mine loading hopper set at an angle relative to the roadway floor and equipped with a hydraulically driven batch-operation transporting element. Aimed at correlating the quantity of material in the hopper and the hopper angle, and at checking and adjustment of theoretical relations and mathematical model, the tests were carried out on an experimental model set described in detail in the article. The experimentation included weight measurement of coarse free-flowing material in the hopper chute during gravity loading at different angles of the chute relative to the roadway floor. As a result of the measurements, a random data array (weight of material in chute) was accumulated. The data processing used the classical methods of mathematical statistics. The calculation procedure is presented in the article. The distribution law of the random values of the loaded material weight is found: it depends on the solution of two main problems in mathematical statistics—estimate of unknown sampling parameters and checking of statistical hypotheses. It is experimentally proved that the random values of the loaded material weights obey the normal distribution law. The agreement of the theoretical and experimental distributions is determined using the Pearson Criterion.
