Sandvik releases +Range mining drill rods
Sandvik Mining claims its new surface mining drill rods and tubes can extend service life by at least 30 per cent and reduce rod changes while improving safety and costs.
The +Range of rock tools are designed and built based on a new exclusive grade steel alloy developed by Sandvik Material Technology which the company says is the key to the tools’ longer life span.
The results, Sandvik says, are fewer rod changes; lower operating, capital and logistics costs; and reduced operator handling requirements.
Sizes available include T38+, T45+, T51+ and GT60+ and includes top-hammer MF (male/female) rods and drill tubes.
According to Sandvik, extensive in-mine tests of the +Range in Australia, Africa, Europe and the Middle East have shown service-life increases of at least 30 per cent and in several cases significantly more.
Sandvik Mining Rock Tools Business Line Manager Craig Johnston says the increased service life stems from Sandvik’s new steel alloy which is far more resistant to heat and thread wear.
"With drill rods and tubes representing a significant part of tool cost in bench drilling, a 30 per cent plus increase in tool life allows customers to drill more metres every shift, and reduce drill costs per metre," he says.
On top of a longer service life, Johnston says the +Range also has safety and environmental benefits.
"Fewer rod changes are required with our new rock tools, resulting in less transporting and handling of equipment. This minimises exposure to risks such as strain and back, arm and hand injuries," he says.
"And because of the extended service life, our new +Range products require fewer shipments and less transporting once on site, and fewer rods to recycle."
"In addition, the manufacturing process for our +Range tools uses less energy and fewer raw materials, further reducing their impact on the environment."
