Abstract

Vibrating screen is one of the important washing equipment in coal washery, and it is mainly used to grading, dielectric recovery, raw coal cleaning, etc. The safe operation of vibrating relates to the coal mine production safety directly. After continuously run for a long time, various faults of vibrating screen cannot be avoided, and beam fracture is one of the most common and serious fault. Now researches for the early detection of beam crack have made some achievements, but many of them can only detect the existence crack, and has not been able to detect the location and depth of crack. In this paper, the crack detection of beam based on fracture mechanics method to solve this problem, so as to realize the quantitative detection of crack. It also can provide the basis for faults predicting of vibrating screen.
