Reduces drill cycle time

Caterpillar’s new MD5150 track drill features a customer-inspired design that drills holes up to 6 inches in diameter. The unit incorporates a rock drill, patented carousel rod changer, new cab, and many other features. The carousel rod changer holds six rods and accommodates multiple lengths and diameters of drill steel. Powerful dual-rod grippers and a unique gate design let the rod and gate move simultaneously, reducing cycle time. The rod changer is supported by a sturdy feed and heavy-duty 8-foot boom that extends to 11 feet for larger pattern coverage with fewer setups. Holes can be drilled within 24 inches of the highwall.

Controlled-flow technology

Flexco designs material transfer chutes using Tasman Warajay Technology. The controlled-flow technology improves throughput and conveyor belt life, and reduces excessive dust, spillage, plugging, downtime, belt wear, material degradation, and noise. Each material transfer system is designed to control the flow of material by keeping it in a continuous stream throughout the transfer. Material discharged from the system is deposited softly and uniformly at a predetermined velocity and direction on the receiving belt so the material settles rapidly and without turbulence.

Excavator transport system

Sleipner’s innovative system for transporting tracked excavators in open-pit mines and quarries is essentially a dolly system consisting of ramps with axles and large wheels. One end of the excavator’s tracks is driven onto the ramps so that the tracks are lifted from the ground. Then the excavator turns around and places the boom on the bed of a dump truck so that the other end is raised from the ground by the boom. The excavator can then be easily and quickly moved to another location, reducing wear on the excavator’s undercarriage and tracks. There are 11 models covering excavator weights from 30 to more than 550 tons. Most models incorporate different ramp sizes to fit different excavator brands and models. The newest model, E550, is the largest and can move 550-ton and larger excavators.

Double-eccentric screening

W.S. Tyler says the new 10-foot-wide version of its F-Class vibrating screen offers the only double-eccentric screening solution for challenging applications that require minimal vibration. This allows the use of multiple machines within the same building or structure without the same reinforcing measures required to house traditional vibrating screens. The company says the screen also keeps screen openings clean, making it possible to process sticky material. The screen follows a tandem design — two completely new modules measuring 10 feet by 12 feet and 10 feet by 16 feet were engineered. In tandem design, the screens can be configured and operated at variable speeds and with different angles of inclination between the modules, creating a banana-type effect.

Designed for harsh conditions

Weir Minerals says its new line of Multiflo dewatering pumps can be modified to handle the largest open-mine pits with the harshest water conditions. According to the company, two of the units — the MF-90V high-flow pump and the MF210MV high-head pump — can be custom built to suit any mine-specific application, ensuring top performance and improving productivity. The pumps are built from corrosion- and wear-resistant materials.

High-pressure grinding

Metso Mining and Construction says it incorporated several key innovations to increase throughput and decrease total cost of operation in its new HRC crusher, which uses high-pressure grinding roll (HPGR) technology. Its patented arch-frame creates an even gap setting across the width of the tires, limiting skewing that can result in downtime. This prevents damage to the roller bearings caused by misalignment. Flanges, used in place of spring-loaded cheek plates, keep material within the crushing zone and prevent material from bypassing the tires, which is said to enable greater circuit capacity and increase overall crushing efficiency.

Hard-rock bodies

Philippi-Hagenbuch says its new HiVol Hard Rock/Ore Bodies take hauling hard rock and ore to an innovative new level. The bodies are designed to easily handle highly abrasive material while minimizing carryback and maintenance requirements. The reduced-weight design is said to keep operators comfortable while allowing trucks to haul at maximum capacities. Each truck body is customized to the individual mine’s application and specifications.
