also be powerful enough to pull a heavily loaded belt up 1,890 ft with a 226-ft lift. The solution was a Baldor-Dodge 920 MagnaGear right-angle reducer and a custom 500-hp totally enclosed, fan cooled Baldor-Reliance motor, a pack- age providing 1 million in.-lb of torque. A Baldor-Dodge fluid coupling provides the soft start of around half a minute that prevents belt jerk and minimizes belt tension. The rest of the Baldor package includes custom-engineered Dodge DM Moment couplings, Dodge-engineered and Mine Duty Extra pulleys, and Dodge USAF and Type E-Xtra bearings. Not only was Goodfellow satisfied with the product selec- tion, he was also pleased to learn about a value-added serv- ice provided by Baldor's System-1 group. This team facili- tates the design, quotation, and order processing of multiple products into a complete packaged solution, arranging for equipment to be preassembled and shipped to the customer location. Tom Childs, project manager for the El Castillo job, said when one considers the number of gearboxes, motors, pulleys and bearings required for the project, especially the 21 grasshoppers, getting the System-1 group to handle the packaging offered a tremendous amount of value. "Because of the number of conveyor belts for this project, we were very happy to get the support from the System-1 group," said Childs. "It was very helpful to have the products delivered preassembled so we could just bolt equipment onto the conveyor and be ready to go. This saved us valuable time and energy, especially on a project of this size." Childs also gave high marks to the Baldor team for its flex- ibility and willingness to work through some of the unique challenges a large project like this can bring. "Our team had great interactions with the Baldor team," said Childs. "We have developed a good relationship that will only get better as we go along. By working together, we deliv- ered a successful project for the El Castillo mine, giving the 90 E&MJ; • JUNE 2014 www.e-mj.com A R G O N A U T G O L D COMPANY PROFILE-PAID ADVERTISEMENT BinMaster is an ISO 9001:2008 certified company that designs and manufactures reliable, solid-state point and continuous bin level indi- cators and inventory management systems used while storing or pro- cessing powders, granules, and bulk solid materials such as alumina powder, sand, aggregates, stone, rock and ores. All of BinMaster's products are designed to help enhance safety and save time while improving inventory management. These sensors are cost effective and help optimize storage capacity, preventing empty conditions and over- filling to keep plants operating efficiently. SmartBob is a proven, highly reliable and accurate inventory man- agement system for monitoring all types of solid materials for one or an entire network of bins, tanks and silos. The weight and cable-based rugged SmartBob2 sensor is for bins up to 180 ft tall. Mounted on the top of the bin, a weighted cable drops to the material surface to take a precise measurement and then sends measurement data to a con- sole, eBob PC-based software or directly to a PLC. Options include models for high or super-high temperatures, measuring submersed solids, and wireless communications. The BinMaster 3DLevelScanner utilizes continuous, non-contact level measurement using dust-penetrating technology to provide unsurpassed bin volume accuracy. It works by measuring multiple points within the silo. This advanced acoustics-based technology is proven to perform in powders and bulk solids contained in tanks, silos and domes. Its unique 3-D mapping capabilities provide a visual rep- resentation of bin contents, detecting irregular material surfaces, cone up or down conditions, as well as sidewall buildup. It is self-cleaning, requires minimal maintenance, and features a variety of extensions and configurations to allow it to be used in a wide range of challeng- ing applications. BinMaster rotaries offer a cost effective means to prevent bin over- flows. The BMRX and MAXIMA+ rotary level indicators feature low power consumption, "de-energized" operation—which shuts down the motor when material is present—and automatic alerts to power failure. BinMaster also provides a variety of vibrating rods to offer side and top- mount flexibility for high, low and mid-level detection. Standard, extended length and high temperature vibrating rods ensure BinMaster has the product to address your needs. The BinMaster tilt switch level indica- tor is a versatile, low-cost indicator that can be used for a wide variety of applications. It can be installed as a plug detector in chutes or hoppers, or used to detect high levels of large heavy materials in tanks, bins or silos. Baldor-Dodge USAF spherical roller bearings and Type E-Xtra tapered roller bearings were selected for the overland conveyors. Harsh-duty sealing systems will extend bearing life and increase reliability. EMJ_pg88-91_EMJ_pg88-91 6/3/14 3:55 PM Page 90
