froth flotation machines impellers

Flotation machine impeller structure is designed according to the cycling route which is effected by the ore grain suspension state. While the ore grain is related to the flotation cell structure and ore characteristic. As deep the cell, we usually adopt large cycle flow, and as wide the cell, we need to enlarge the impeller peripheral speed.
