Flotation drive unit upgrade

Improve energy efficiency and power transmission for high-capacity cells, as well as reducing maintenance requirements and overall lifetime equipment costs, with the Metso Drive Unit Upgrade.

Upgrades that improve performance to help you reach your sustainability targets

Reduced energy consumption

eDrive direct-drive gearboxes improve efficiency and use less energy

Lower environmental impact

The eDrive complies with all environmental regulations relating to noise levels and lubricant usage

Ease of maintenance

The eDrive unit requires an oil change every 1-3 years, depending on the lubricant

Increased safety

The design avoids oil leaks and protects your process from contamination

Benefits

Tailor-made gearbox for each specific application
Smaller environmental footprint
Low maintenance requirements
Long service life of critical wear parts
Higher availability
Improved energy efficiency and power transmission

As ore grades decline, the need for higher-capacity flotation cells (with volumes of 70 m³ or more) continually increases, in order to process a larger amount of ore to achieve the same level of metal output.

Cells with large volumes require a relatively large mixing mechanism, which in turn requires more torque from the drive unit. The increased torques cause traditional v-Belt drives to become less effective as they consume more power and greater wear of critical parts. They also have inferior power transmission compared to gearbox-driven drives.

All new Metso high-capacity flotation cells are supplied with Outotec e-Drive units. Replacing the belt-driven drive units in higher-capacity cells with the Outotec eDrive direct-drive gearboxes will improve equipment efficiency, makes maintenance easier, and reduces the overall lifetime costs.
