K-HEE™ impeller upgrade increases mill uptime
A copper mine in Canada was looking to maximise wear life of their impellers and improve shut-down intervals.
The site were using legacy design impellers which were dictating when the ‘mill shuts’ were scheduled. The site had impeller life averaging at 900 hours using legacy AH series parts and up to a maximum of 1,400 hours using expensive, specialised impeller materials. The mine had tried low cost replicas from various sources, but found that the resulting life (as low as 600 hours) combined with poor fits and performance, cost them substantially more in additional downtime than the savings made on the impeller price.
