Description

Technical Field

[0001] The utility model relates to the technical field of coal, in particular to a novel dust-reducing coal washing machine. Background Art

[0002] Coal washing is an indispensable process in coal deep processing. Coal mined directly from the mine is called raw coal. Many impurities are mixed into the raw coal during the mining process, and the quality of coal is also different. Coal with low intrinsic ash content and coal with high intrinsic ash content are mixed together. Coal washing is an industrial process to remove impurities from raw coal or to classify high-quality coal and low-quality coal. The products produced after the coal washing process are generally divided into: gangue, medium coal, Class B clean coal, Class A clean coal. The finished coal after the coal washing process is usually called clean coal. Through coal washing, the cost of coal transportation can be reduced and the utilization rate of coal can be improved. Clean coal is an energy source that can generally be used as fuel. Clean coal of bituminous coal is generally used for coking. It needs to go through industrial processes such as desulfurization and impurity removal to meet the standards for coking.
