When FLSmidth visited the site to assess the situation, the concave liners were only lasting an average of 2.75 million tonnes, while the mantle liners had an average lifespan of just 0.75 million tonnes. As a result, liners needed replacing more frequently than they had in the past. This extended the time the crusher was out of service for maintenance and impacted the mine’s productivity.
On top of this, the mine wanted to increase throughput of its SAG mill. This placed additional demands on the crusher to deliver an optimal feedstock to the mill. A new M 02-23 0000-30-ENG V2 crusher lining solution was therefore required.
The solution we proposed would more than double the lifetime of the liners, and ultimately help to raise annual production at the mine. This not only strengthened the mine’s financial performance, but also brought important sustainability and health and safety benefits.
Changes to ore geology were causing operational challenges with the liners of a West African gold mine. In response, FLSmidth provided a customised wear solution that boosted liner life, optimized crusher performance, and resulted in an overall increase in mine throughput.
