E Q U I P M E N T G A L L E RY Exploration Drill Meets Latest ATEX Standards Deister BFO1820 Screen with Isolation Base Sandvik announced its DE100 series of compact core drills for surface and underground exploration applications now includes the ATEX certified DE130x drill rig. The DE130x, according to Sandvik, is a fully certified exploration drill rig for underground coal applications and is compliant with the latest ATEX standards. The design is based on Sandvik's proven DE130 core drill, pictured above. According to the company, its modular design, depth capacity of 815 m (2,674 ft) N-size rod, feed force of 4.7 mt (10,350 lbf) and pull force of 6.3 mt (13,820 lbf), makes the DE130x a highly capable unit, featuring a completely redesigned power unit which monitors hydraulic oil temperature, electric motor temperature and incoming power. Intrinsic safety circuits are also included. The drill unit is certified and designed for maximum surface temperature of +150°C (class T4). In accordance with Europe's ATEX standards, some of the parts included on the standard DE130 92 E&MJ; • JANUARY 2013 have been replaced by steel parts on the DE130x. Additional features include an extra gauge for rod holder surveillance on the control panel and a wire emergency stop on the feed boom for increased safety. mining.sandvik.com New Options for Mine-duty Screens Deister Machine Co. has introduced two new equipment options for mine-duty screens. The company's Exciter Vibrating Deister Exciter Mechanism Mechanism is designed for use with large linear stroke screens and feeders. Multiple units can be positioned in series, and linked by flexible shaft couplings to provide better bearing life in conjunction with aggressive G-force. According to Deister, high-tech CNC manufacturing processes ensure tight tolerances and precision fits for the entire assembly, while innovative seal, shaft and bearing designs provide a rugged unit that is easy to maintain, especially when combined with the Deister System Saver Oil Filtration system. Removable external counterweight slugs allow for easy output force adjustment over a wide speed range. The Exciter Mechanism can be driven by V-belts or direct drive flexible shaft. Another option for large screens is the Deister Isolation Base, which incorporates a secondary set of support springs, as well as shock absorbers, further isolating the forces generated by the vibrating screen frame from the stationary structure. www.deistermachine.com Safety Eyewear Offers Bluetooth Connectivity Honeywell Safety Products says its Uvex AcoustiMaxx Stereo Bluetooth eyewear is an all-in-one solution combining maximum impact protection with hands-free voice communication.
