| Abstract: | The energy efficiencies of the acceleration nozzles of ejector and pneumatic jet mills are compared. Mathematical models are proposed for the acceleration of a two-phase mixture in the nozzle and the jet, and a procedure is put forward for optimizing subsonic nozzles and open-loop jet mills. The gas-dynamic perfection of the nozzles of pneumatic jet mills is assessed, and the initial particle-size range where the mill efficiency is highest is determined. |
