The BF flotation machine impeller is composed of the closed double frustum, may produce the strong circulate under slurry.
Capacity: 0.3-24m³/min
Model: BF type, XJ type, XJQ type, GF type, etc.
Materials: copper, zinc, lead, nickel, gold, etc.
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water.
Froth flotation can selectively separate core minerals from middlings or tailings, making them high-grade mineral concentrate. Since froth flotation can separate minerals from already processed concentrates besides the primary ore, it is considered to have high efficiency in recovering minerals.
To check the bolts before starting the machine and to use hands instead of impellers to prevent the sediment from adding the burden of electromotor.To adjust the height of strobe carefully to keep the stabilization of liquid level and scrape the mineralized froth to the launder. The impellers and stators should have a distance and should be changed when they are worn. The bearing in the pump should be maintained every three months.
01. The effective flotation volume of one tank is increased; the output is increased; the work efficiency is improved, and various rough selection, sweeping, and selection operation modes are satisfied.
02. The degree of foam refinement is high, and the accuracy of flotation is increased by 3-5%.
03. Compared with conventional machines, it can save 1/3~1/2 of electric power and has lower operating costs.
04. The unmanned automatic control system has the functions of suction and flotation and does not require any auxiliary equipment.
