Level Measurement And Control In Flotation Tank Cells

A single ltm2 probe can be installed per flotation tank cell. the ltm2 probe sends a pulp level signal that is utilized by the flotation cell level control system to maintain pulp level depth at setpoint. actual pulp level measurement is in the set range below the froth lip height. at the bottom of the bracket is a 40 mm polypropylene bushing.

Level measurement of a flotation cell is not as straightforward as it first sounds because we actually measure the depth of the froth. of interest in a flotation cell is how deep the froth is above the slurry, as this determines the grade of the resulting concentrate. the typical range for a froth depth is 600 mm from the top of the flotation.
