Selective Crushing of Run-of-Mine as an Important Part of the Hard Coal

To obtain commercial product of required quantitative and qualitative parameters, hard coal must be subjected to a number of processing operations. Preliminary stone removal from run-of-mine is one of them. Methods of such removal, including the method of selective crushing are described. Design solutions for a KOMAG-type device for dry stone removal Aiming at the low efficiency of traditional mechanical cutting methods in hard coal seams, a multi-impact cutting technology was proposed, which was to design a hydraulic system inside the drum. In this paper, by analyzing the working process of the multi-impact drum, the corresponding mechanical model was established and the overall Study on shearer drum structure design and coal-breaking
