Sandvik Tundo™ RH650 DTH hammer increases mine output while reducing operating costs and carbon dioxide emissions. The innovative piston and air cycle design enable high-performance rates at low air consumption, reducing drilling costs, fuel burn and carbon footprint.
Features
-
Sustainable and reliable
The air cycle design of this hammer significantly improves drilling efficiency, increases fuel economy and reduces CO2 production. The potential savings grow with the size of the drill rig fleet. An average-size mine operated by 15 Sandvik DI650 or equivalent, each running 5,500 hours per year, could reduce their diesel consumption by 3.3 million liters, meaning a carbon footprint reduction of 8,580 tons a year.
-
Reduce fuel consumption by 20%
This hammer can increase mine output while reducing operating costs and CO2 emissions for the drill rig. The innovative solid piston and efficient air cycle design enable high-performance rates at low air consumption, meaning fuel consumption is reduced by up to 20%. This means less engine load, less heat and less wear.
-
Compact design
The significantly smaller size and weight allow for easier and safer handling. Compact design allows more evenly distributed stress on the retainer shoulder, meaning less wear on the bit. External porting frees the piston from cross-drilled holes, reducing stress-induced failures and increasing reliability.
