For the daily production of the concentrator, the operating cost of the flotation machine is mainly composed of energy consumption, equipment depreciation, and consumption of wearing parts. The main vulnerable parts are the impeller and cover. At present, the flotation machines used in the beneficiation industry are A-type flotation machine, SF-type flotation machine, BF-type flotation machine and JJF-type flotation machine. The material of the impeller and cover plate is mostly rubber. The impeller and cover plate are worn out. The service life is generally 3-8 months. The impeller and cover plate are one of the main consumables in the concentrator. Where the impeller cover is prone to wear, the polyurethane sieve manufacturer will come to explain for everyone:
Impeller replacement The used impeller may cause some damage. If the impeller encounters one of the following conditions, the impeller should be replaced.
1) Cracks appear on the surface of the impeller.
2) More holes are formed on the impeller surface due to corrosion, erosion or cavitation.
3) The impeller cover and blades become thin due to scouring, which affects the mechanical strength.
4) The impeller's mouth ring hub has severe partial wear and no repair value.

The material of the impeller cover of the flotation machine includes rubber impeller, nylon impeller, polyurethane impeller cover, polymer impeller, etc.
Polyurethane is a high-strength, high-wear-resistant material. It is a high-molecular polymer between general rubber and plastic. It has the high elasticity of rubber and the unique high strength of the plastic family. It is a unique high wear-resistant material. , Elastic material.
After the impeller and the cover plate are worn, the gap increases, the cutting effect of the slurry decreases, the bubbles become thicker, the degree of mixing of solid, liquid and gas decreases, and the degree of bubble dispersion decreases. When the abrasion is severe, it will significantly affect the flotation index.
High quality and low price polyurethane impeller cover, please look for Chaishang Trading Co., Ltd. It is your good choice.
