CONVEYOR ENGINEERING OCTOBER 2018 • E&MJ 47 Paraburdoo mine to mark the start of the project. "We are extremely proud of having been selected to provide some of our most-advanced machines to this im- portant project for Rio Tinto, the state of Western Australia and the country as a whole," said Dr. Hubrich. "This only serves to reinforce TAKRAF as a leading global provider of mining and bulk mate- rial handling equipment and we look for- ward to working together with Rio Tinto in other important projects in the future." This project forms part of Rio Tinto's broader sustaining capital program estimat- ed at $1 billion a year over the next three years. The company is also investing in re- placing depleting assets with an estimated $2.2 billion expected to be spent on re- placement mines over the next three years. Beumer Installs Another Curved Conveyor The U.S. subsidiary of the Beumer Group, an international supplier of conveying systems, was recently awarded a con- tract to design, supply and install a near- ly four-mile overland conveyor at Knight Hawk Coal's Prairie Eagle mine in central Illinois, USA. The Knight Hawk project is a strategic win for Beumer, allowing the company to broaden its mining sector footprint, accord- ing to Brad Williams, vice president of sales and business development for Beumer's Conveying & Loading Division, based in the Kansas City area. "We are very accustomed to handling coal and coal residuals in the power industry, but we are excited about the opportunity to focus on a project direct- ly in the coal mining sector," Williams said. Prairie Eagle is the hub of Knight Hawk's coal mining operations, process- ing and shipping more than 80% of the company's 5 million tons per year of coal production. Opened in 2005 as a surface mine, the Illinois facility was expanded to two underground mines, a prep plant and multiple truck loading facilities. The curved troughed belt conveyor will carry coal from a mine portal to its main the prep plant. The overland conveyor will allow Knight Hawk to seal a portion of its underground mine and bring coal to the surface near its current mining activities. Commissioning of the new conveying sys- tem is scheduled for April 2019. "This project is right up Beumer's alley from a technology standpoint, as it will be- come our third overland curved troughed belt conveyor installed in North America in the last five years," Williams said. "Our curved conveyor technology allows for a single-flight system that costs less to in- stall and operate than a conventional con- veying system, and will offer Knight Hawk long-term financial and environmental benefits when compared with trucking." The original request for proposal called for four straight conveyors re- quiring three transfer towers," Williams explained. Beumer's winning proposal features a single-flight curved conveying system that eliminates the cost of tower steel, and greatly reduces the quanti- ty of components and necessary spare parts. It will reduce the dust, noise, maintenance and operating costs asso- ciated with the transfer points, and offer 98% reliability compared with roughly 92% reliability for four conveyors oper- ating in series.
