Abstract：In order to solve the problems such as large water resource consumption,high water content of cleaned coal,heavy load of coal slime water treatment system and large coal slime output when raw coal is easy to degrade in water,an intelligent dry separation system of power coal lumps based on PLC and image intelligent recognition system was designed.The working principle and system composition were introduced,and preparation tests were carried out.The test results show that the clean coal ash is 12.99%and the gangue ash is 81.26%for the raw coal with particle size between 25 mm and 150 mm.The yield of clean coal is 86.30%,the yield of gangue is 13.70%;when the theoretical separation density is 1.81 g/cm3,the total mismatch is 2.01%,cleaned coal contains 0.95%gangue,and gangue contains 1.06%clean coal.When the equal error density is 1.80g/cm3,the total mismatch is 1.75%,and the overall sorting effect is favorable.
