Study on Crushing and Separation of Coal and Gangue

Abstract:

In this paper, the pressurization of irregular ores was first discussed so as to make an analysis on the causes for the great difference between measured result and actual ores, and then a preliminary pressure experiment was made on a certain quantity of coal and gangue samples extracted from Du'erping Coal Mine through electronic universal testing machine. Therefore, the selective crushing and separation of coal and gangue was preliminarily tested through the testing machine so as to obtain the selective crushing pressure distribution curves of coal and gangue, and then the curves were drawn based on its numerical distribution. The two curves drawn in this way were placed in the same coordinate, and the optimized control of the separation and selection of coal and gangue was made according to the probability values in the coordinate, so as to find a reasonable pressure boundary value and also prove that the separation and selection of coal and gangue are with certain feasibility.
