Breaker Technology (BTI) and Telsmith have new products for MINExpo 2016 on a 325 m2 display at the Las Vegas Convention Center. The theme for the booth, #1448, is ‘MINING ALL IN’.
BTI will be launching its new ScaleBOSS 3D scaler at the event. The ScaleBOSS offers a five-axis boom, providing enhanced flexibility and superior coverage in a light, compact design. The Mine Runner APV will also be on display, a mining utility vehicle offering more power and increased safety with less maintenance and a lower total cost of ownership.
Both vehicles offer BTI’s Advanced Breaking and Tramming (ABT Control- patent pending) and hydraulic wheel drive (HWD), providing more traction and power with reduced emissions. BTI says its “mining utility vehicles are a modern day solution for a new generation of mining productivity and safety.”
ScaleBOSS features an ergonomic ROPS/FOPS certified operator cabin, in which the HVAC system maintains excellent personnel safety, comfort and visibility. The machine is optimised for 3 x 3 to 5.5 x 5.5 m headings, the ScaleBOSS 3D Scaler meets the demands of a new generation of mining and safety.
Heavy-duty, compact construction makes it easy to manoeuvre and it withstands severe conditions.
The breaker function’s dedicated, open-centre hydraulic circuit helps simplify identification of maintenance needs.
Mine Runner has been engineered from the ground up to be a leader in personnel safety and operational flexibility. “The ever increasing payload requirements and tramming distances have exceeded the capabilities of the typical repurposed highway 4×4 style truck. Unlike many over the road type vehicles being modified for use underground, the Mine Runner is purpose designed and built for the underground environment,” explains Andy Jackson, BTI Engineering Project Leader, Mobile Equipment Systems.
Both the primary braking (service brakes) and the secondary braking (emergency brakes) have been designed and tested to meet and exceed the CSA Braking Standard and Performance for Underground Mining Machines. CAN/CSA – M424.3-M90.
Powered by BTI’s HWD fluid controlled power train, the Mine Runner is capable of easy customisation to a optional configurations without hindering performance or longevity of components.
The Telsmith T900 cone crusher is a “true mine-duty machine designed and engineered to deliver maximum uptime, productivity, safety, and ease of maintenance,” the company says. Offering a capacity output range from 550 to 2,100 t/h, with up to a 15-in feed size, the T900 “is rated with the largest in-class clearing stroke, the highest in-class crushing force,” and boasts 670-kW performance.
“In designing the new T900, Telsmith places a key emphasis on safety and serviceability,” says Albert Van Mullem, Director of Engineering for Telsmith. “For example, its large clearing circuit is engineered to safely and quickly allow any uncrushable materials to pass; and its numerous innovative serviceability features differentiate the T900 from conventional units that typically require significantly more time in routine service,” he says.
Telsmith engineers outline a number of T900 reliability and ease-of-maintenance benefits. For reduced maintenance time and costs, the T900 is designed with eight cylinders (versus 12 cylinders in conventional units), yet offers the largest crushing force availability. The unit also offers a new and improved patent-pending anti-spin feature that prevents head spin to extend manganese life. Like other key components, it’s mounted on top of the machine to offer top-service access. It’s also designed to operate with pressure lubrication oil, while eliminating the use of a gear box and a separate hydraulic circuit.
Next, the company states, “the T900 features the largest-in-class, patent-pending hybrid bearings. Unlike roller bearing machines, these large hybrid bearings offer both a static and dynamic lift – which results in far greater lift to efficiently carry the crushing forces. Also, hybrid bearings feature a washer and ramp design that replaces the conventional use of a socket, socket liner, and head ball – all of which typically require time-consuming removal when servicing the machine.
Additionally, the Telsmith T900 is nitrogen-free and is engineered with a patented release system that eliminates the need for maintenance-intensive hydraulic accumulators. Even more operational cost savings stem from features such as a patent-pending concave (bowl liner) retention system which consists of a specially-designed and positioned lip ring that centres the bowl and achieves retention.
