ZJJF series flotation machine is designed on the basis of principle of Wei Muke flotation machine. It is an ideal self-inspiratory mechanical agitation type flotation machine. The machine has the following features: inspiratory capacity is relatively stable; solid particles suspend better, Impeller installation is shallow depth, Stator has long life, Liquid surface is balance and high Sorting Efficiency. Generally, ZJJF series flotation machine is always applied with ZSF series flotation machine to form a joint unit; ZSF flotation machine is used for inhalation slot of pulp self-absorption while ZJJF series flotation machine is used for DC slot. Thus, operations space is level configuration without foam pump to get high sorting indicators. ZJJF series and ZSF series also play their respective advantages.
