New Cat ultra-class surface mining drill

of mines’ sampling and analysis require- ments. It designs solutions for exploration and ore characterisation, grade control, pro- cess plants and port shipment. The highest quality equipment is sourced and applied to a laboratory solution to achieve accurate sampling, effective sample preparation and detailed sample analysis. Each laboratory design is unique, he emphasises, as it must suit each custom- er’s particular operating conditions and strategic goals. The design process there- fore demands close collaboration with the customer and a detailed examination of mined material and process demands. This ensures that the laboratory generates exactly the type of analytical data that the plant operators require. “With our world-class mineral research and testing facilities, we are constantly pioneering innovations that add value to customers,” he says. “Our automated solu- tions also offer consistency and traceability, while improving ergonomics and eliminating hazards to laboratory personnel.”  Integrated machine protective features and interlocks help keep operators safe and the machine up and running by pre- venting potential failures or misuse. With Cat Electronic Technician, troubleshooting is quick and easy. Drill electronics also pro- vide a common platform for the integration of automation solutions. The MD6380 features a spacious cab that offers superior operator comfort and machine control. Intuitive multifunction joystick controls and touchscreens pro- mote efficient operation. Display screens are adjustable to suit the driller’s reach and line of sight. The driller can easily tram from a seated position. With a full-length driller window, large pane glass around the cab and four standard high-definition cam- eras, operators have excellent views of key areas. The machine also features Drill Assist, which delivers automated functions includ- ing auto level, auto retract jacks, auto raise and lower mast, and auto drill. The drill depth monitoring system helps to reduce both over- and under-drilling. The MD6380 incorporates Cat Terrain for drilling. The proven MineStar technology provides precise hole location, produc- tion reporting and strata reporting. Terrain seamlessly connects to Cat Command, offering a path to remote operation and autonomous drilling. 

Designed for large blasthole production drilling, Caterpillar’s latest ultra-class drill, the MD6380, provides the optimal mix of on-board air, feed force, rotary torque and machine mobility. With a hole diameter

range of 251 to 381 mm, single-pass hole depth of 19,8 m and multi-pass hole depth of 39,5 m, the new drill is designed for large scale mining. The MD6380 powertrain is designed

to efficiently manage loads gen- erated by the compressor and hydraulics, delivering superior fuel economy. The MD6380 compressor is configured with electronic regulation and vari- able volume air control, allowing the driller to perfectly match compressor output to drill tool and application needs. It also lowers stand-by pressures while the machine is in idle, further improving fuel efficiency. The MD6380 is capable of pulldown force of 49 895 kg and rotation torque of as much as 20 880 Nm. The proven Cat 3512C diesel engine produces 960 kW and delivers emissions perfor- mance equivalent to U.S. EPA Tier 2 and EU Stage II. The pow- ertrain offers extended durability and high availability to help boost utilisation and lower costs. The MD6380 is controlled through proven Cat electronics.

FLSmidth takes lab sampling to new heights With the general decline in ore grades in mining, FLSmidth’s market-leading expertise in mineral sampling and laboratory automa- tion holds increasing value to mines.

this needs technology that can sample high volumes, maintain rapid turnaround times, and deliver quality results.” Only then can plant operators respond to laboratory data in real time, which is one of the keys to effective plant optimisation. With over 30 years experience, FLSmidth has been a pioneer in laboratory systems integration, as well as driving automation in the laboratory environment. “ Ou r p a r t i c u l a r

“The more you understand about the characteristics of the ore entering your pro- cess plant, the better you can treat it,” says Martin Matthysen, director, SPA (sampling, preparation and analysis), sub-Saharan African and Middle East at FLSmidth. “But

expertise in laboratory automation is now rec- ognised world-wide,” says Matthysen. “This is why we have supplied 95% of all automated laboratories to the global mining industry constructed over the past dozen years or so.” The company’s offer- ings address all stages
