BS-K Air Flotation Machine

When flotation machine works, slurry is inhaled from the bottom of the cell to the space between impellers. Meanwhile, the low-pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole cell.


Description
When flotation machine works, slurry is inhaled from the bottom of the cell to the space between impellers. Meanwhile, the low-pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole cell. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the re-mix with air. The remained slurry flows to the next cell until becomes tailing.

Structure features:
1 Main shaft is hanging on the machine frame, light structure and easy installation.
2 Impeller is cone shape; stator is radial, strong agitation and lower power consumption.
3 U shape tank is made and lower sand settlement.
4 The diameter of the impeller is smaller thus lower peripheral speed.

Performance features:
1 Lower power consumption and saving 30-50% energy.
2 Well floated particles and higher recovery.
3 Light wearing of the spare parts so longer service life of them.


Notes:
1 Mechanical agitation, non self air inhalation, non pulp suction and required height difference (300-400mm) between flotation groups.
2 It can be combined with XHF cells to be direct cells.

Application:
It is widely used in enrichment for non-ferrous metals, black metals and non-metals in medium and big flotation factories for the roughing and scavenging concentration.

Warm reminding:
1. Please inform the product name, model and specification when you order.
2. Please inform the ore feeding direction; otherwise, we make from the left feeding.
3. We won’t offer and install the middling and discharging pipes if customers don’t tell the requirements and offer the flow sheet.
