Background

The client wanted to improve the performance of the wear materials, especially the penetration and service life. The mine is located in a protected area where blasting is prohibited; therefore the material must be extracted from the ground and so penetration becomes an essential characteristic as well as having very robust wear parts that are easy to replace.

The ground freezes to a depth of 1.5 m in the winter and the teeth had a service life of 4 days (with the machinery operating 22 hours/day). The client had previously used wear parts of other brands and encountered penetration problems, breaks and difficulties when replacing the parts. The straddle adapters also did not have the desired resistance.

The client decided to use MTG's comprehensive solution for protecting the bucket, which included the new MTG Systems StarMet Cast Corner adapter.

Results

Using the “MTG Full Bucket Solution” the service life of the wear parts was significantly increased without losing any penetration effectiveness.

Less breaks and easier to replace parts have reduced machinery down time due to G.E.T. maintenance.

No breaks of the MTG Systems StarMet Cast Corner adapter have occurred since its installation in spite of working under extreme conditions.

Customer satisfaction

“In the past we rotated the tooth in order for it to resist at least 10 days. Now this is no longer necessary. Penetration is very good and replacing teeth is accomplished easily and quickly”.

“Replacing the teeth is really easy and fast. It takes us 8 min to replace 5 teeth”.
