Background
Coal dressing is also called coal washing, and the process of selecting clean coal meeting the user quality requirement from raw coal. The coal for coking has certain requirements on ash content and sulfur content, and cleaned coal which is washed and selected must be used. The lithofacies composition of coal, as well as the quantity, type, nature and distribution of minerals in the coal, are factors that influence the selectivity of coal. The common processes of coal preparation plants include jigging, dense medium cyclones, dense medium shallow slots, moving sieve jigging, flotation and the like aiming at the difficulty of raw coal selectivity. Other coal dressing methods include air separation, spiral dressing, etc.
However, when the existing coal separator is used for coal separation, because raw coal directly slides from the vibrating screen, the retention time is short, the raw coal cannot be sufficiently separated and screened, and thus the same batch of raw coal can be thoroughly distinguished only by screening for multiple times, so that the problems of high cost, low efficiency and increased labor burden of workers in the coal separation process are caused.
