Research on Structural Optimization and Practice of Heavy Medium Cyclone in Coal Preparation Plant
Overview of the basic principle of using a heavy medium cyclone in coal preparation plants,which can separate particles of different densities in suspension.Three optimization parameters were set,namely the diameter of the bottom flow outlet,the diameter of the overflow pipe,and the insertion depth of the overflow pipe.Based on the orthogonal experimental method,structural optimization design was carried out,and it was found that the sorting effect was best when the above three parameters were 38 mm,64 mm,and 92 mm,respectively.The optimized dense medium cyclone was applied to the coal preparation plant engineering practice and industrial test was carried out.It was found that the ash content of middling coal could be increased from 38.38%to 42.43%by using this structure,which improved the separation quality to a certain extent and laid a good foundation for the economic benefits of the coal preparation plant.
