XCF/KYF Flotation Cell
Capacity: 0.2~50 m³/min
CXF flotation machine is an air-inflation mechanical agitation flotation cell with slurry suction.
KYF flotation machine is an air-inflation mechanical agitation flotation cell without slurry suction.
XCF/KYF Flotation Cell/Machine Overview
Flotation machines constitute the basic equipment for the recovery of useful minerals from non-ferrous ores and other raw materials by flotation. They can also operate as individual flotation cells.
Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies. The Flotation Cell is aerated to produce bubbles and agitated to keep the solids particles in suspension in the pulp. A flotation cell is an appliance in which froth flotation of ores is performed. It has provisions for receiving conditioned pulp, aerating this pulp, and for separate discharge of the resulting mineralized froth and impoverished tailings.

Advantages
The XCF/KYF flotation cells feature a simple yet robust structure with strong stirring capacity, ensuring efficient and uniform air dispersion for optimal air-slurry mixing. These cells minimize tailings deposits, operate at low peripheral speed and energy consumption, and have wear-resistant components for extended service life. Utilizing mechanical agitation, they eliminate the need for self-inflation or pulp self-priming while maintaining effective ladder configurations between workspaces.
The XCF model includes a unique stator above the impeller, creating a special negative pressure zone that enables self-priming pulp, making it ideal for suction-type flotation setups. Meanwhile, the KYF model operates similarly but without self-priming. Both models can be combined in series or parallel configurations, providing flexible and high-performance ore flotation processing. Their low energy consumption, high efficiency, and durability make them ideal for mineral separation applications.
XCF (Suction Type) – Self-priming Slurry Capacity
The “double-layer impeller + diffuser” structure achieves:
✔ Suction height up to 1.5m (30% higher than comparable international models)
✔ Suction volume up to 2.5 times the tank volume
✔ Zero auxiliary pump configuration, saving 15-20% energy
KYF (Aeration Type) – High-efficiency Aeration System
Utilizing a “hollow shaft + gas distributor” design:
✔ Volume utilization up to 85% (conventional models ≤ 70%)
✔ Microbubble generation rate increased by 40% (bubble size 0.2-1mm)
✔ Gas volume adjustment range 0.1-1.5m³/(m²·min)
Combined Advantages – Forming a Closed-Loop Flotation Circuit
The XCF, operating as a suction tank in conjunction with the KYF aeration tank, achieves:
✔ Energy consumption reduced by 25-35%.
✔ Reagent consumption reduced by 15%.
✔ 50% improvement in separation stability.

Structures & Working Principle
XCF/KYF Flotation Cell/Machine Structure
XCF/KYF flotation machine is composed of a tank, a large isolation plate impeller with top and bottom blades, a seat stator radial blade, a split disc cover, a split center tube, a connecting tube with air-bleed hole, a bearing body, hollow main shaft, and the air adjustable valve.
XCF/KYF Flotation Cell/Machine Working Principle
When the flotation machine is at work, the rotation of the impeller makes the slurry all-around via the tank bottom absorbed from the downside of impelled into inner-vanes of the impeller, where low-pressure air is produced by the blower goes into via hollow shaft and the air distributor of impeller chamber at the same time. After a full mixture of the slurry and air among vanes, they are pushed out in the inclined upward direction from the upper half of the impeller around and go into the tank via steady flow and orientation by the stator. Air bubbles rise to the foam stability area, and after the concentration process, the froths overflow from the overflow weir into the froth tank. Another part of the slurry flows toward the lower part of the impeller, then through the impeller agitation, they are mixed to form mineral-laden bubbles again, and the rest of the slurry will flow to the next tank to become tailings eventually.
