Dosing Control Systems

Dosing Control System for flotation separation adopts special arithmetic to perform dynamic control over chemicals amount for flotation separation mainly according to green ore amount, froth layer thickness, total metals in green ores, concentrate grade, metal recovery rate.

The dosing system handles the filling process only. The mechanical parts of the filler, e.g. container feed, pumps, lowering of the filler nozzles etc, are controlled by the supervisory system, start commands being communicated via the PROFIBUS DP interface. The system is self-monitoring, adapting to changes in mechanical and physical flow conditions. When air bubbles are detected, the dosing is immediately reduced for the nozzle in question until the danger has passed, thus avoiding overfilling and shutdown of the entire line.

The automatic dosing control system addition of flotation medicine is an important link in the flotation production process. Addition quantity and accuracy directly affect the product quantity, quality and benefits. Traditional manual adjustment is neither accurate nor timely. The application of the flotation automatic dosing control system overcomes the disadvantages of manual adjustment, reduces medicine consumption in flotation production, brings direct economic benefit to the ore dressing plant, and reduces labor strength. According to the flotation process parameters for raw ore quantity, foam layer thickness, total metal quantity in raw ore, concentrate grade and metal recovery, it utilizes an advanced calculation to dynamically control flotation medicine addition. Therefore, the optimization of separation effect in flotation is achieved, medicine consumption is reduced and metal recovery is improved.
