Development of a Grains Fluidized Separating Apparatus with Pulsed Airflow

This paper introduces the principle of a new fluidized grain separating apparatus with a pulsed airflow and its main characteristics.Some para meters affecting the performance index were analysed .The mathematical nodel was established through test and statistic verification. The optimum parameters were calculated with the optimization method. These lay a fivst foundation for further study and mprovement.
