Energy-saving applications of FLSmidth forced aeration flotation machine rotor and stator

A large iron mine adopted FLSmidth forced-air flotation machines, which are equipped with the patented Next Step rotor-stator combination. Compared with traditional forced-air flotation machines, it optimizes the shape and matching profile of the rotor and stator, realizing efficient energy transfer from the mechanical device to the slurry.

After application, the system delivered significant improvements:

• The energy consumption of the flotation machine is reduced by 28%.
• The rotor and stator wear evenly, and the service life is twice that of similar equipment, reducing maintenance downtime.
• The iron ore recovery rate increased by 4.3 percentage points.
• The concentrate grade increased by 2.1 percentage points, significantly improving the comprehensive flotation efficiency.
