WEG slip ring motors to drive milling operations at Vale Verde copper mine

WEG says it has supplied two M Mining slip ring motors to mining company Mineração Vale Verde to drive the main mill of a 4 Mt/y plant at its Serrote copper operation in Alagoas, Brazil.

The M Mining slip ring motors come with a power output of 5,400 kW and rated voltage of 13,800 V. They will be fitted to the FLSmidth-supplied plant

The WEG M Mining slip ring motor has a new automatic brush lifting system, which differentiates the WEG product from other motors on the market.

The motors were specially developed with electromechanical characteristics that provide durability, resistance and robustness, being able to operate in harsh environments like mine and cement sites.

In addition to the above advantages, M Mining line motors, with an automatic brush lifting system, incorporate operating logic, resources for fault investigation, monitoring of operation via HMI and prevention of improper manoeuvres, simplifying and reducing maintenance costs, motor installation, operation and maintenance, WEG says.

Vale Verde will be provided with technical assistance and WEG aftersales support, the company added.

Mineração Vale Verde said in early February that Serrote remained on track for first production in the second half of 2021. An August 2019 definitive feasibility study outlined a project able to produce around 20,000 t/y of copper-equivalent over an initial 14-year mine life from a low-strip, open pit mine supplying this 4.1 Mt/y processing plant.
