Considering each product＇s density, volume, and suspending liquid assignment, combining the separating mechanism of the cyclone and the rela- tive formulas obtained from scientific experimentation and practice, the structure parameter was determined by calculation. This provides a more scientific reasonable method for determining the structure parameter of the unpressurized feeding three-product heavy-medium cyclone.展开更多
