Abstract
The plough discharger is the key device of the belt conveyor, which targets the wear problem of the baffle. In this paper, the coal particle model is established by EDEM, the normal cumulative contact energy and tangential cumulative contact energy of discharge baffles with radius of 1.6m, 2.5m, 4.5m and 8m are obtained, as well as the average velocity of coal particles contacting discharge baffles with different curvature radii, and the wear of the baffle with different curvature under the same working conditions are studied. The optimal radius of curvature was selected through analysis. It provides a basis for the future design of the discharger baffle.
