MAINTENANCE WEAR PARTS correct lubricant at the optimum frequency. This can re‐ sult in a reduction in bearing temperature and smooth temperature spikes due to under lubrication. Klübermatics enhance preventive maintenance routines due to the reliability of the delivery system compared to the scheduling of manual applications. Automatic lubri‐ cation systems save time because they minimize lubrica‐ tion maintenance route. The time to lubricate 100 lubrication points on your con‐ veyor equipment every 14 days can be drastically re‐ duced by installing Klübermatics and exchange every six months without any tools and without stopping produc‐ tion. This frees maintenance staff to focus on improving reliability in other parts of the plant. Installation Correct installation and lubricant choice are essential for maximizing the benefits of the Klübermatic system. Each Klübermatic installation begins with a survey by the Klüber and Perma engineering team and continues with installation support and periodic operational reviews. During the survey, the team will identify the opportuni‐ ties for automatic lubricators, the installation design, and the lubrication requirements. Klübermatics can be used in all areas of a plant including the quarry, mixing beds, conveyors, kilns, mills, ventilation systems, motors, pumps, extruders, silos, bagging, palletizing, fans and everywhere in between. The unique features of the Klübermatic program include controlled and metered delivery of the correct lubricant, automatic lubrication systems engineered to meet the specific requirements of the application, and the com‐ bined installation and after sales support by the Klüber and Perma engineering team. Klübermatics provide the operator with peace of mind that machinery will not fail during critical operations because of improper lubrica‐ tion. Klüber Lubrication, www.klueber.com Engine Oil for Mining Applications Chevron Products Co., a Chevron U.S.A. Inc. division, maker of the Delo brand of technologically advanced engine oils, lubricants and coolants, highlights the per‐ formance of Delo 400 Multigrade SAE 15W‐40 by using the example of a mining operation – the ASARCO Ray copper mine – in Arizona. Delo 400 Multigrade SAE 15W‐40 is a premium‐quality engine oil designed for pre‐2007 engines and higher sulfur fuels (> 500 ppm sulfur). With exceptional soot dispersancy and wear control, Delo 400 Multigrade SAE 15W‐40 protects cylinders, pistons, rings, and injectors against wear and corrosion, providing optimum service life and minimal maintenance. ASARCO's Ray copper mine operates a fleet of 39 haul trucks, 21 of which are Liebherr T 282s. These 400‐ton ultra‐class trucks have 3,600‐hp engines and operate 22 hours a day, seven days a week, in some of the Southwest's harshest conditions. Given the negative financial impact of equipment complications, ASARCO has implemented a preventative maintenance program www.rockproducts.com that includes the use of Delo 400 Multigrade SAE 15W‐ 40 diesel engine oil. After inspecting one of the facility's 20V MTU 4000 en‐ gines that had delivered 21,900 hours of service with 500 hour drain intervals, the engine components were found to be in "excellent conditions." The combination of the MTU engine, with good maintenance practices, and the use of Delo 400 Multigrade allowed ASARCO to increase engine life and achieve significant cost savings per engine per year. Chevron's Delo product family includes engine oils, pre‐ mium lubricants and extended life coolants that pro‐ vide premium performance and bottom‐line value for diesel powered vehicles. All Delo products are covered under the Delo Warranty Plus program, which provides bumper‐to‐bumper pro‐ tection against lubricant and coolant related failures as described in the Delo Warranty.
