Aker Flotation Machine Technology
Principle OF AIR DISPERSION
Principle OF AGITATION
The unique double flow agitation effect of the AKER flow Flotation Impeller.
The patented AKER Impeller / Stator design creates the following effects:
- Pumping from the middle of the impeller.
- Divides the return flow to the impeller into two separate flows.
- The strong under flow of the impeller results in strong agitation and prevent the flotation cell from sanding.
- The more quiet upper flow of the impeller carries the air bubbles with the minerals to the surface of the flotation machine.
Aker Bearing Assembly
Selection of high quality materials and attention to design have produced a rugged bearing assembly with bearing life-time more than 20 years of operation.
The AKER Bearing Assembly is equipped with upper and lower spherical roller bearings and double seal system on both sides of each bearing.
The bearing housing is also designed with a condense water relief gate to prevent water entering the bearing system.
Typical Automatic Pulp-Level Control System
Principle of operation:
An acoustic level transmitter measures the distance between the top plate of the float and the transmitter and sends proper signal depending on level of the pulp and / or the froth. The position of the float (pulp level) is displayed on a digital display and if it deviates from the set point a corrective action is triggered to the electric actuator of the control valve. The controller also sends signal to the process computer. It is possible to adjust the pulp level both locally and from the process computer.
An additional optional acoustic transmitter sends a signal (froth level) to the process computer so it indicates both level and froth thickness.
