Sandvik Beauty and the Beast double for Buxton Quarries

Over 10 m tonnes of limestone will be drilled and blasted between the two quarries.
Sandvik DI600 is the largest of the DI range and represents the latest in mobility and versatility with high large diameter drilling performance. All in a modern design with enclosed engine, and OK for road transport without an escort
Sandvik D245S is the smallest drill from our factory in the USA and we have been supplying this type of drill to Tunstead for over 30 years. In the USA the D245S is described as ‘compact' although it actually weighs over 39 tonnes compared to DI 600 28 tonne. It has a fixed mast with inside loader and 9.15 m (30') drill pipe with simple direct hydraulic controls, open engine and compressor. The large 2 man cabin has enough room for a second seat and small fridge.
Cemex Dove Holes required a drill to replace their existing machine, but they wanted something extra. With annual production at the quarry exceeding 4.0 m tonnes, the Sandvik DI600 was selected to ensure these high targets would be met, which may involve the possibility of double shifting. Cemex's main considerations in selecting the DI600 included its powerful CAT C15 engine, high output compressor, high torque rotary head, large cabin, frame and undercarriage and improved access for service. The machine will use 5" and 6" DTH hammers and will be required to track long distances.
At Tunstead Quarry, which has an annual production in excess of 6 million tonnes per year, Tarmac has been using the larger Sandvik blast-hole type machines for over 30 years. Two rigs are utilised in order to remain ‘on top of the job', and 6" DTH hammers are used exclusively. Tarmac say they have tested a smaller ‘contractor' type machine but were not persuaded to change. According to the company, the significant weight of steel used in the D245S ensures the longevity of the drill rig.
