Minerals and mining

The annual global volume of minerals comminution has expanded to crushing more than 20 billion tons of minerals. More than 30,000 crushing equipment units, such as impact crushers, jaw crushers and cone/gyratory crushers, are used around the world. Wear part consumption of different crushing equipments is estimated to be 500,000 tons annually.

However, the volumes of mining applications, such as primary crushing and milling processes, are even higher and present an even bigger challenge for materials technology .

By introducing innovative materials technology solutions, Metso Materials Technology has demonstrated multiple wear part lives in tough mining and minerals processing applications. Comparison of the wear loss of standard manganese steel and two new Metso grades (CCG steel and metal matrix composite, see graph) shows a significant difference.
