新型流化床分选机试验研究

In this paper, a new-style dry separator was designed. It has eliminated the scraper device of the traditional dry separator by using a vibratory working surface of counter-inclination angle to transport gangues. The materials separation characteristics and gangue transport behavior are studied in the new-style dry separator. Feeding methods has little effect on separation efficiency; when the stiffness of the bed surface was small, the bed surface was easier to deform and it would influence the transfer effect; the transmission capacity of the fluidized bed firstly rises and then was constant with the increase of the feed.
