SF Flotation Machine
PRODUCT INTRODUCTION
The SF flotation machine is the abbreviated term for the froth flotation machine, which is a type of mechanical equipment used to complete the flotation process. Flotation is a mineral processing method widely applied in mineral production. Through agitation and aeration, certain mineral particles selectively attach to air bubbles, rise to the surface of the pulp, and are scraped off to form a froth product. The remaining portion stays in the pulp, achieving the purpose of mineral separation. The flotation machine is primarily suitable for separating metallic minerals such as gold, silver, copper, iron, lead, zinc, molybdenum, nickel, and aluminum. It can also be used for the roughing and cleaning of non-ferrous metals and non-metallic minerals. It is an indispensable and crucial piece of equipment in the mineral processing production line.
ADVANTAGE
-
Dual-blade circulation for effective flotation. The flotation machine’s impeller features backward-inclined double-sided blades, enabling dual circulation of the slurry in the tank, which facilitates the suspension of coarse-grained minerals.
-
Horizontal configuration for easy process adjustment. Each tank integrates three functions: air suction, slurry absorption, and flotation, forming an independent flotation circuit without the need for any auxiliary equipment. The horizontal layout allows for convenient process modifications.
-
High air intake with low energy consumption. The machine utilizes mechanical agitation for self-aeration and self-slurry absorption. The large clearance between the impeller and the cover plate ensures high air intake and low energy consumption.
-
Wear-resistant vulnerable parts and low maintenance costs. The low peripheral speed of the impeller extends the lifespan of vulnerable parts. Additionally, high-wear-resistant components are installed around the parts, effectively protecting the tank from wear and reducing maintenance costs.
WORKING PRINCIPLE
The ground ore is mixed with water and necessary reagents during or after grinding in a mixing tank to form a slurry. This slurry is then injected into a stirring slurry tank, and air is introduced into the slurry to create a large number of bubbles. Some mineral particles that are not easily wetted by water, generally referred to as hydrophobic particles, attach to the bubbles and rise together with them to the surface of the slurry, forming a mineralized bubble layer. Meanwhile, other mineral particles that are easily wetted by water, generally referred to as hydrophilic particles, do not attach to the bubbles and remain in the slurry. The mineralized bubbles containing specific minerals are then collected and removed, thereby achieving the purpose of mineral separation.
