New products from MTG help cut costs

7159 MTG unveiled two new product lines at Bauma 2014 in Shanghai, China.

7936 VR Steel has been appointed as its mining dealer for China, in addition to its existing territory in South Africa.

The StarMet rope shovel products are now available for the buckets of the P&H4100 and 178 Caterpillar 7495 mining shovels and include teeth adapters, lip and side protectors. They have been designed with cost effectiveness and reliability in mind. MTG's Twist hammerless locking solution strikes a balance between penetration and abrasion. Shrouds can be swapped to the opposite side of the bucket to allow full wear. The range includes self-sharpening teeth.

A metallic retainer system has been introduced as a solution for hot slag applications with the StarMet system. “The main advantage of the StarMet hot slag solution when compared to KingMet is that with StarMet you will only need to change the pin and the retainer due to the wear, while with KingMet you would also have had to change the adapter,” said Joan Cesar, MTG’s product manager.

MTG's range now covers 90% of the rope shovel segment. Testing of the new products at a quarry in Germany led to a cost reduction of 42% for high abrasive and 56% for extreme abrasive. This resulted in 1% increase in production and a 2% reduction in fuel consumption. Tests in a copper mine near Santiago, Chile showed a 31% decrease in tooth wear.
