Replacing the liners of a primary gyratory crusher is a time-consuming undertaking for any mine. The less frequently this task has to be performed, the better. Eliminating just one concave segment change-out every year not only adds several days of precious production time, it also reduces maintenance costs and risk exposure. It’s a win-win scenario for everyone involved.
The best way to eliminate liner change-outs and extend maintenance intervals is by using wear parts that are optimized for the application and are longer lasting. This is exactly what Buenavista del Cobre set out to do when it chose to rely on Metso to provide optimized wear parts for its primary crushers.
