Global high-tech engineering group Sandvik will once again be among the top global exhibitors to participate at Electra Mining 2012, where it will be introducing new technology alongside a selection of its core products.“This is a particularly special year for us as Sandvik celebrates its 150-year anniversary of global business,” says Alice Ward, Sandvik marketing and communications manager for Africa. Originally known as SandvikJernverk, the company entered the African market through the development of rock drills and its partnership with Atlas Copco in the 1940s. A production facility was established in South Africa as early as 1948. Sandvik has always worked with the most advanced technology of its time. The group’s cluster of expertise has grown stronger over the decades and today it has patents, drawings and expertise pertaining to hundreds of thousands of advanced products in alloyed steel, titanium, cemented carbide and ceramics. It’s this core expertise in metals and materials that is the root of the company’s global success. Highlights Mining equipment featured on the stand will include the company’s new DM300 mobile bolter, the DR580 surface mining drill, a compact hybrid crusher and, from its construction range, the DI550 construction drill and the DS210L-M low profile mechanised roofbolter. The new DM300 mobile bolter offers semi-automated operation, reducing the operator’s contact with the drilling operation to a bare minimum and therefore significantly minimising the risk of hand injuries. The DM300 has four drill rigs in the front of the machine, enabling two operators to fit four bolts in a row in less than half the time that a twin boom bolter would take to install four bolts in a row. This machine is able to do side wall drilling with two optional drill rigs fitted to the rear of the machine.
The DR580, a diesel-powered DTH crawler-mounted surface mining drill, is ideal for drilling production, pre-split, pioneering, dewatering and reverse circulation in-pit grade control holes. This drill boasts the highest air pressure in its class to achieve maximum drilling performance. The cab is ergonomically designed, providing a comfortable cabin that operates on a swing concept to give superior visibility and enhanced safety. The operator also benefits from the ability to achieve precise positioning, an easy drill set-up and greater accuracy. The heavy-duty DR580 is manoeuvrable and stable, and offers ease of maintenance.The Sandvik hybrid crusher is known for its compact design and its minimum generation of unusable fine material. The DS210L-M is the only low profile mechanised roofbolter on the market at the moment. People safety is the major benefit with this machine; since the roofbolt drilling and installation processes are completely mechanised, no-one is exposed to unsupported ground during the drilling and roofbolt installation processes. The company’s DI550 construction drill is ergonomically designed for productivity and user comfort, and is being hailed as the first of the new generation of down-the-hole drill rigs. This drill features a 324 kW diesel engine and a 24.4 m3 compressor air flow at 24 bar pressure, making the machine a perfect match for the 4-inch and 5-inch DTH hammers. This careful match of power and hammer size makes the rig uniquely productive, reducing fuel consumption and keeping operating costs as low as possible. Cost effective machine performance is further enhanced by other advanced features such as active diesel RPM control, optimised diesel RPM level during drilling and active control of compressor running temperature. On top of high performance, simple and comfortable machine operation is a key feature of the DI550. With a modern, accurate control system and simple icon displays and comprehensive service information, the new DI550 enables seamless cooperation of man and machine. The rig’s modern, over-pressurised ROPS and FOPS certified cab with advanced ergonomics, efficient air conditioning and excellent visibility further adds to operator comfort. The large windshield comes with a strong safety bar that is easy to open for cleaning. An efficient dust collector with non-stop cleaning decreases the amount of dust emissions to the environment and improves filter lifetime, reducing the need for maintenance. Other features that translate into easy maintenance and low downtime include the engine compartment’s open layout, easy cooler cleaning, modular compressor control system and simplified electric system. All daily maintenance points are located at ground level to simplify the process and improve safety of service personnel. A fast fuel filling option and large fuel tank further cut costly downtime.
