Accurate, reliable level control is key to maintaining the availability, capacity, and metallurgical performance of your flotation process. Common challenges include accounting for fluctuations in cell levels caused by changes in volumetric flow, and the high wear of parts such as plugs, sockets, and sliding components that can result in frequent unplanned maintenance.

An effective level-control system comprises a reliable and accurate measurement instrument, accurate control valves, and an optimized control system. It is generally accepted that an internal dart valve is the most efficient and reliable way to accurately control the flow of slurry out of a cell. The Metso dart valve is electro-pneumatic and has long-stroke actuators to ensure smooth and accurate control. It is constructed from robust stainless steel, with polyurethane or rubber sockets and dart plugs that have a long lifetime.

We also offer level measurement solutions such as mechanical ball floats and the state-of-the-art Metso LevelSense system, which is a low-maintenance solution that enables accurate measurement of the slurry-froth and froth-atmosphere interfaces. By upgrading your level control system with the latest  Metso technology you can improve flotation cell throughput, performance, and reliability. We offer level control upgrades for all Metso TankCell® and OK cells.
