[0002] Coal gangue is a kind of solid waste discharged in the process of coal mining and coal washing, which is a black gray rock with low carbon content and harder than coal associated in the process of coal formation.

[0003] In the process of coal mining, coal seam roof and floor often mixed with excess ingredients, among which coal gangue accounts for a larger proportion, and needs to be cleaned to improve the quality of mined coal, and heavy medium shallow groove separator is used for coal cleaning. The heavy medium shallow groove separator is based on the Archimedes principle, and the raw coal to be separated is layered and separated according to the density difference in the suspension liquid with certain density. The light product less than the medium density will float on the top and flow through the overflow weir with the flowing medium, becoming clean coal product, and the material greater than the medium density will sink to the lower part of the heavy medium separation groove, and be transported out of the shallow groove by the low-speed chain scraper, becoming gangue.

[0004] Due to the existence of coal gangue in raw coal, the chain plate produces bending deformation and cannot be used normally. When replacing the chain plate, the end of the chain plate and the transmission chain need to be disassembled, which consumes a lot of time.
