Mining Business Bets Big on MINExpo
World’s largest mining exposition reconvenes in Las Vegas to showcase advances in equipment, technology and services
By Steve Fiscor, Editor-in-Chief
So, what can delegates expect at MINExpo 2016? E&MJ asked the NMA and several of the leading equipment suppliers that question. The association is building on its prior successes with some interesting twists. Some vendors are keeping their MINExpo 2016 activities under wraps, but a few did share their plans.
As a point of reference, MINExpo 2012 set new records as far as the number of exhibitors (1,865), exhibition space (860,000 ft2) and attendance (52,000). That, however, was a different time, when business for both coal and metal mining companies was brisk. In the ensuing four years, the coal industry has suffered a rout. Prices for metals weakened and some have since recovered, but not to 2012 levels.
Organizing an event of this magnitude is no easy task. With the help of others, Moya Phelleps, senior vice president, member services for the NMA, manages MINExpo. Describing what delegates would see at this year’s event, she said many of the exhibitors are bringing large equipment and unveiling new models. “Participating in MINExpo is a huge financial commitment and they not only want to support the mining business, but they believe strongly that the mining industry has a bright future,” Phelleps said. “In 2012, MINExpo hit all of the high points. The last 18 months to two years, however, have been particularly challenging for both sectors, coal and hard rock mine operators. The number of exhibitors is about the same as this time four years ago, and so are preregistration levels for delegates.”
Phelleps said visitors can expect to see new technologies and services that can lower production costs, improve productivity and improve safety. Technical experts will be available to assist operators with daily issues and challenges.
Visitors will also notice some differences. As many as 25% of the exhibitors are new companies. There will be several international pavilions on the show floor, including Canada, China, Australia, Chile, Germany, France and Sweden. “France and Sweden are new this year,” Phelleps said. At this point, 840,000 ft2 at the Las Vegas Convention Center has been booked, which is all of the indoor space, but Phelleps said they do have limited outdoor space available.
Acknowledging that times are difficult, the NMA has been working with its producer members to get as many people from the mines to the show floor as they can. At its annual fall board meeting in 2015, the NMA decided to waive the registration fees for all miners whose companies are members of the NMA. “All of our producer members and those members developing properties in the U.S.—Barrick Gold, Freeport McMoRan, Rio Tinto, etc.—will have company-wide complimentary registrations no matter where they reside,” Phelleps said. “This is a big commitment on our part. It was well received by the producers. All of the producers have agreed to bring large contingents of personnel to the show and some are planning to host company meetings at the event. The vendors have committed to bringing their customers to the show as well.” This is a $100 savings before the August 12 deadline, and $200 afterward.
“We have organized 20 sessions covering a number of topics: safety, markets, research, equipment maintenance, water, surface mining, underground mining, automation, exploration, bulk materials, processing, etc.,” Phelleps said. “These discussions will take place on the mornings of September 27 and 28.”
As it has in the past, the NMA will also host two awards luncheons: the Sentinels of Safety (Tuesday, September 27) and the Department of the Interior’s Sustainable Development and Reclamation Awards (Wednesday, September 28). Hecla is sponsoring the Sentinels of Safety. “A silver miner celebrating its 125th anniversary, Hecla is also a signatory to NMA’s CORESafety program,” Phelleps said. “On Wednesday, the Office of Surface Mining will present coal operators with reclamation awards. The Bureau of Land Management will recognize metal- nonmetal miners with sustainable development and reclamation awards.”
The NMA is also expecting strong international participation. “In 2012, about 35% of the attendees came from abroad and we expect that number to be about the same,” Phelleps said. “We have formed 30 delegations, building on the 20 delegations that participated in 2012.”
These delegations are part of the International Buyers Program organized by the U.S. Department of Commerce (DOC). The DOC Commercial Services division selects a limited number of exhibitions and they work with the embassies to bring qualified buyers to the exhibition. “With the delegations, we offer them an opportunity to present market briefings,” Phelleps said. “People who want to learn about these foreign markets can speak directly with knowledgeable people who know them best.”
As the excitement builds toward the event, the NMA plans to keep everyone informed by whatever means necessary. At MINExpo 2012, the association used social media well. It has evolved, and they plan to take full advantage of this medium to communicate with delegates. “We will have a large social media presence and that will continue to grow toward the show,” Phelleps said. To stay informed, delegates should register and follow MINExpo on Twitter, Facebook and Instagram.
Similar to 2012, there will be a MINExpo app for smartphones to assist with planning prior to arrival and navigating the floor on-site. The association will also publish an online directory, which will remain on the website (www.minexpo.com) for a year after the event. There will also be an Export Interest Directory associated with the International Buyers Program. As of press time, more than 1,800 companies were planning to exhibit at MINExpo 2016. What follows is a small sampling of what some of them have planned for the event.

Thyssenkrupp Introduces the
Largest Gyratory Crusher
The Industrial Solutions business area of thyssenkrupp (Booth 3051) will unveil the world’s biggest gyratory crusher. The new machine is the KB 63-130, which despite a roughly 14% larger mantle diameter of 130 in. (3.3 m), weighs much less than its predecessor at 490 metric tons (mt). Its throughput of up to 14,000 mt/h is more than 30% higher than that of the predecessor model. The unit weighs less because thyssenkrupp’s engineers have done away with the usual design principles.
The housing parts have a similar “fish belly design” to other thyssenkrupp gyratory crushers. This special design reduces stresses in the crusher housing and increases its strength despite the optimized weight.
Technical highlights of the new crusher include the rotatable countershaft assembly for setting tooth clearance, and the eccentric bearing assembly with top bevel gear. As well as allowing better balancing of the machine, the new bearing system permits a much more compact design as well as maintenance-friendly assembly and disassembly.
Sandvik Promotes Safety
Sandvik (Booth C-7309) will showcase the latest in its portfolio of innovative equipment and services, ranging from a single drill bit to mine automation. The company offers a wide range of automation solutions that miners can apply right now to maximize the full potential of their mine site while significantly improving safety. Depending on a customer’s requirements, it can provide AutoMine for autonomous solutions and OptiMine for information management or a combination of these two—all resulting in improved safety and productivity.
Sandvik will also launch a number of drill rigs, including its latest addition to the DD422 series. The DD422iE uses electric battery power instead of a diesel engine to eliminate emissions during tramming. The patented electric driveline system on its latest automated mining jumbo enables battery recharging during drilling. Sandvik DD422iE burns less fuel, also generating less heat and noise than conventional drivelines. There are many other new and innovative solutions on Sandvik DD422iE designed to increase productivity and simplify maintenance, to help ensure maximum rig availability. For underground miners, Sandvik will unveil the latest addition to its modular 400 underground range of ITH long hole drill rigs with automation capability.
The newly introduced Top Center (TC) drill bits, incorporating the most significant upgrade to face drilling bits in decades, is one of the Sandvik highlights at MINExpo. The new design features a so-called “raised front,” elevating two or three front buttons—depending on diameter size—a few millimeters above the gauge buttons located on the periphery of the bit. Additionally, the front buttons are set at a slight angle relative to the symmetric axis of the bit. The raised front creates a slightly recessed hole bottom pattern that alters the rock-breaking action in order to achieve improved performance. This, together with a new cemented carbide grade GC80, which combines toughness with a softer center, further extends the service life and long grinding intervals. More launches will be revealed at the show.
The company will also showcase its advancements in the field of comminution and miners will see the latest in the range of crushers in the quest for more eco-efficient comminution solutions— one of these being Sandvik CH865, the midrange mining crusher for high-reduction tertiary and pebble applications. Intelligent systems on Sandvik CH865 enable real-time performance optimization, while smart, compact design solutions reduce dynamic loads, and minimize engineering and installation work.
As previously announced, Sandvik and Getman Corp. entered into a global distribution agreement under which Sandvik Mining will be the exclusive global distributor of Getman’s products. Getman representatives will be available at the Sandvik booth to discuss solutions in underground drilling, rock enforcement systems and aftermarket services.

Hilliard Unveils New
Hilliard Corp. (Booth 1763) will unveil a new braking system that uses brakes that it has developed, tested and certified. For more than 30 years, the company has been supplying braking systems for draglines, electric shovels, conveyors, mine hoists and mills. The new systems, according Rick Kallenborn, mining industry sales representative for Hilliard, will replace existing systems with a standardized product that is more user-friendly and will allow miners to reduce their inventory. Because of the harsh environment and extremely high loads, most mines push their braking systems to the limits. Eventually the seals begin to leak and then the brakes fail. “We want to eliminate these catastrophic failures,” Kallenborn said. “We have implemented several modifications to improve maintenance. These new systems are completely interchangeable with the old systems. The mounting configurations and the footprint are the same. The arm kits replace the ‘left’ and ‘right’ arms with one standardized arm. The changeover can be implemented quickly.” And, quicker repairs mean less downtime for maintenance, he explained.
Wirtgen Showcases Surface
Mining Technology and More
Acknowledging that powerful and durable equipment is essential, Wirtgen (Central Hall 8801) will showcase two innovative solutions for mining: the 2500 SM Surface Miner and the MOBICAT mobile jaw crusher from Kleemann. The robust Wirtgen surface miners and crushing and screening plants from Kleemann offer high reliability and efficiency.
With a feed rate of up to 330 mt/h, MOBICAT MC 110 Zi EVO is one of the highest-performing and most efficient machines in its class, according to Kleeman. The generously sized feeding unit, the continuous feed system (CFS), as well as the level control in the crusher, guarantee optimal capacity utilization without interruptions. The productivity is also increased by thorough primary screening. The independent double deck pre-screen filters out fines with oscillating movements. On the one hand, this protects the machine as it is less prone to wear, and, on the other hand, ensures a higher quality end product. Another advantage of the MC 110 Zi EVO is the diesel-direct electric drive, which boasts significantly lower fuel consumption than comparable jaw crushers.
