[0002] The connection of each process of cyclone material sorting is a crucial link in the entire sorting process.

[0003] Currently, after the cyclone group is sorted, the material discharged from the underflow main pipe enters the next sorting equipment by connecting the underflow main pipe outlet of the cyclone group with the feed pipe of the next sorting equipment through a flange. However, the flange connection is prone to loosening over time, and once loosened, material leakage will occur. Utility Model Content
