Setting the standard

Sandvik has unveiled the first of its new generation of down the hole (DTH) drill rig and it is said to offer improved productivity and user comfort in 5" hammer drilling. The new DI550 is also the first rig from the company to have been fully developed in Finland using the company's combined knowledge base. The rig features a 324kW diesel engine and a 24.4m3 compressor air flow at 24 bar pressure, which Sandvik has said makes the machine a perfect match for the 5" DTH hammer.

The new DI550 rig offers improved productivity and comfort

460 Sandvik has unveiled the first of its new generation of down the hole (DTH) drill rig and it is said to offer improved productivity and user comfort in 5" hammer drilling. The new DI550 is also the first rig from the company to have been fully developed in Finland using the company's combined knowledge base.

The rig features a 324kW diesel engine and a 24.4m3 compressor air flow at 24 bar pressure, which Sandvik has said makes the machine a perfect match for the 5" DTH hammer. This careful balance of power and hammer size results in a productive rig that keeps fuel consumption and operating costs to a minimum. Cost-effective machine performance is further enhanced by other advanced features, such as active diesel RPM control, optimized diesel RPM level during drilling and active control of compressor running temperature.

Sandvik has said that along with good performance, simple and comfortable machine operation was a strong focus of the development. The rig has a control system with simple icon displays and comprehensive service information, the new DI550 enables seamless cooperation of man and machine.

Specification

Breaking, Drilling & Blasting

GPS technology improves rig performance

Advances in technology are helping to deliver both improved hole straightness and BLAST detonations for better fragmentation. No matter how carefully the load and haul functions and crushing and screening processes have been designed, if the feed stock does not match the design, any efficiencies are lost. Improvements in drilling techniques and blasting technology are helping to deliver benefits that mean the actual blast matches the design more closely than ever before.
