GTUMX diamond coring bits features the Boart Longyear UMX formula. UMX bits use an advanced metallurgical formula that is impregnated with large synthetic diamonds. The formula optimizes high penetration capabilities with longer bit life and allows the GTUMX to turn easily from one ground formation to another. GTUMX also features the Razorcut design on the face of the bit, designed to expedite diamond exposure and allow the bit to begin cutting right out of the box. Wide tapered waterways improve surface flushing and cutting while reducing wear on the innerdiameter of the bit, particularly in broken, abrasive conditions. Boart Longyear will launch an AXT size GTUMX bit first in the South Africa region, followed by additional bit size releases and expansion into the Asia Pacific, Europe and Latin America regions. www.boartlongyear.com Tool Carrier Offers Greater Breaking Power, Stability Brokk AB has unveiled its model 100 alltool carrier, featuring a more compact design and 35% greater breaking power than the model 90. The 100's low-profile configuration, featuring a three-piece boom design, is less than 4 ft tall and offers a lower center of gravity for greater stability. A new load-sensing hydraulic system with improved hydraulic capacity helps generate superior breaking power when paired with the included Atlas Copco SB152 breaker. Maximum horizontal reach is 12 ft (3.6 m), with vertical reach of 14 ft (4.2 m). According to www.e-mj.com Brokk, the new machine is the first in the industry to deliver the flexibility of true 360° working performance, without compromising stability, productivity or reliability. The Brokk 100 is powered by a 32amp, 20-hp electric motor and weighs 2,183 lb (990 kg) excluding attachments.. Recommended maximum weight of attachments such as beam manipulators, breakers, crushers, drills and shears is 331 lb (150 kg). Additional improvements and features include upgraded cooling capacity, impact-resistant steel covers, improved rubber pads on the outriggers and LED lights with virtually unbreakable covers. www.brokk.com ic view of structure and composition of an ore. The MLA EXpress is well-suited for typical mining operational environments; the simple design requires no special operational skills. Multiple analytical modes enable the flexibility to accommodate a variety of ore types and analysis requirements. Special detector and pulse counting technologies enable extremely high count rates for fast, precise analytical results. Most importantly, according to FEI, a low price and low operating costs make MLA Express a cost-effective solution for a broad range of mining operations. www.fei-natural-resources.com Economical Bench-top Mineral Analyzer FEI recently released MLA EXpress, a low-cost, bench-top, automated mineralogy analyzer that is claimed to be capable of extending mineral liberation analysis to a broader scale of mining operations. Automated mineralogy involves a scanning electron microscope (SEM) and x-ray spectrometer to obtain a microscopDECEMBER 2012 • E&MJ; 91
