Supersonic Jet Mill PJM TOP. The jet flow of theoretically over Mach 2 promotes pulverization by mutual impact of particles. The high speed vortex flow promotes separation of the fine particles and the coarse particles. Classification is performed by the special classification mechanism with the coarse particles-return port. The model N, which ...
In response to some problems that occurred when a steel mill in China transitioned to automatic steelmaking, a high-Mach-number oxygen lance was designed and forged. The designed oxygen pressure was 1.01 MPa; at this high oxygen pressure, the Mach number of the nozzle outlet could reach 2.15. A three-dimensional two-phase flow model was established by numerical simulation, and …
