area of effective coal-loading capacity in the test was specially divided in order to reduce test errors. The effective coal-loading area started from the drum coal cutting side of the bearing pedestal... smaller. The coal quantity inside the drum also decreased, and the centrifugal force borne by the coal mass increased. As the distance between the bearing pedestal and drum end was large, some......
