The KYF circular flotation machine is a highly efficient, energy-saving flotation device that can be widely used for the separation of various metallic and non-metallic minerals. It is flexible to operate, easy to control, stable in operation, and convenient to maintain. The circular tank structure facilitates onsite installation, saves space, and reduces investment costs. When the flotation machine operates, the motor drives the rotor via a hollow shaft. The slurry enters between the rotor blades from the lower part of the rotor, while the air is introduced through the hollow shaft into the rotor chamber. The slurry and air mix between the rotor blades and are discharged from the upper part of the rotor. The flow is guided and stabilized by the stator before entering the tank. The mineral-attached bubbles rise to the surface of the slurry, forming a froth layer. In the center of the tank, the rising bubbles and the slurry they carry encounter a compressed froth cone, which directs the froth to the overflow weir. The froth, carrying the concentrate, flows over the weir, while the remaining slurry is discharged from the slurry outlet and either sent to the next flotation cell or discarded as tailings.
