Portugal’s mining strategy may favour copper over lithium
Portugal already has the largest copper mine in the European Union, operated by Lundin Mining.
Continuous improvement to bring maximum productivity through performance, that’s our commitment. The launch of the new RH 460 series delivers just that. Reliability, productivity and efficiency make up the driving force behind this new series of DTH hammers.
As the going gets tough, Sandvik get tougher.
The RH 460 design concept takes the standards we have set even higher, providing higher impact energy and drill performance while maximising productivity in almost all ground conditions. The range is designed to focus on reliability and endurance to ensure peak performance at all times.
The new series is designed to reduce costs in drilling and have the ability to perform its required functions under stated conditions for a specified period of time.
Design, test and evaluate
The new design promises to prolong hammer life and increase drilling penetration rates.
Through enhanced air cycle the RH460 will reduce fuel costs. Power level will increase productivity through better lubrication capabilities, improvements in resistance against galling and developments in the piston bearing design. Put quite simply, piston and hammer life will be dramatically increased.
The new RH460 family will begin with the launch of the 4”, 5” and 6” hammers. All versions are designed to utilise bits with generic shank types.
