The concept of agitation (energy input) by oscillating plates or grids to promote an environment with homogeneous turbulent agitation in Flotation Equipment cells has been used in several studies.

The effect of power intensity on the flotation kinetics of quartz is strongly dependent on both particle and bubble size. For small bubbles, high flotation rates are achieved at very low power intensities. For larger bubbles, flotation rates increase with increasing power intensity for fine and intermediate particles, while an optimum power intensity is reached for coarser particles.

The force on the driving shaft is measured by an S-type load cell mounted in line, and the force transmitted to the slurry is the difference between the force with slurry in the cell and without slurry. An optical sensor on the drive shaft measured the frequency of oscillations. The average power input is calculated using the measured force, the velocity of grid stack and oscillation frequency.
