Abstract

Batch separation of solid particles in a fluidized bed classifier is investigated. Evaluations of separation performance are made in terms of product purity, Pc and total efficiency, TE. Results show that the cut size of a fluidized bed classifier is easily changeable over a wide interval and is controlled by simply changing the airflow. Separation of finer particles from bulk materials is less efficient than the separation of larger particles, although higher purity of bottom product may be obtained. For batch operations, better separation of a given cut size can be obtained after an optimum time of operation, at gas velocities higher than the terminal gas velocity. An approach for dealing with the prediction of Pc and TE with time in a batch fluidized bed classifier is discussed. Results show that total efficiency of up to 88% at an optimum elutriation time may be obtained in the fluidized bed classifier used in this work.
