There are three main types of JXSC flotation equipment, namely mechanical agitation flotation machine (BF, ...
Flotation is a complex physicochemical reaction process involving the three phases of gas, liquid and solid. The scale-up process of the flotation machine does not mean to increase geometric dimensions of key components (such as the tank cell, rotor and stator) of the flotation machine simply in proportion, but it requires the full consideration …
machine used. Flotation machines, in general, may be categorized into four different classes: (i) mechanical or con-ventional cells; (ii) energy-intensive pneumatic cells; (iii) column cells; and (iv) froth separators. Of these, mechanical Sotation cells have dominated the min-eral industry since the early days of Sotation and
