Xinhai produced a wide variety of flotation machines, including inflatable flotation machine, inflatable mechanical flotation machines and self-absorption air mechanical flotation machines three types. During operation, the major costs include depreciation of equipment, energy, wearing parts consumption. The main vulnerability of consumption is flotation machine impeller and cover consumption. Currently on the market, SF flotation machine impeller is mainly made of rubber, the life span is generally 3-8 months, for this defect, Xinhai made some design improvements.
Xinhai takes the spraying polyurethane as SF flotation machine impeller production materials. Spray polyurethane is widely used in mining, electricity, coal and other industries, which can effectively enhance the abrasion resistance of the impeller. After using the spray polyurethane wear resistance equipment is seven times of using the vulcanized rubber material, and is three times of the use of ultra-high molecular polyethylene material. During flotation processing, sprayed polyurethane impeller can withstand aggressive medium pH of 3-11, with a strong anti-corrosion properties. And the use of the impeller of the material has a very strong adhesion properties, for different metals, non-metallic substrates it can find a suitable primer and adhesive. Since the spray polyurethane has a weak sensitivity to moisture and temperature, the construction is very convenient.
In the design of SF flotation machine impeller, taking the need of achieving slurry double loop in the flotation tank, Xinhai use backward double impeller. And there is a larger gap between the impeller and the cover, largely it enhanced the air intake amount in the flotation machine. The rotating peripheral speed of the impeller is slow, it further reduces wear, and extend the life span of SF flotation machine impeller.
Xinhai, the production of SF-type mechanical flotation machine, with the improvement of impeller wear in the actual production applications, it enjoys a high praise of customers.
