62 VDMA | 2014 VDMA MINING SUPPLEMENT VDMA Customized System Solutions for Bulk Materials The ever-increasing technical demands in the bulk materials industry are reflected in the particular expectations of the user. Manufacturers who can supply all of the equipment and bring a project from concept to completion are in high demand. The Beckum-based Beumer Group with affiliations around the globe develops customized system solutions for conveying and loading systems. Beumer also acts as the main contractor on behalf of its cus- tomers. "A significant trend is that more and more clients want to commission their systems in a turnkey state," said Dr. Gerd Oberheuser, head of system technology for the Beumer Group, re- garding the increased market requirements. "EPCM [engineering, procurement and construction management] is more than a buzz- word. I t's an enhanced form of project management. And, this trend can be seen in many parts of the bulk materials industry, especially open-cast mining." "For a quotation to be accepted, contracts are often only placed on an EPCM basis," said Dr. Oberheuser. This means that, as well as supplying the equipment, Beumer is responsible for the whole process. This includes the design of the entire system, the inst allation, the commissioning and the instruction of subcontrac- tors. Not only does a high availability of machines and systems play a decisive role, but also optimum support. For this reason, Beumer has set up competence centers in the Czech Republic, in Austria, at its headquarters in Beckum, and in North America. These take care of research and development, sales, project man- agement and purchasing. With its solutions, the Beumer Group helps users to work more cost effectively and in a more environmentally friendly manner. The com- pany's belt conveyors enable companies to transport large quantities of bulk material from the mine to the port as cost effectively and as quickly as possible. Conveyors hold distinct advantages over trucks. Road building is expensive, and as production grows so does tr uck traffic. Added to this are the operating costs and emissions caused by the fleet—both with regard to fuel consumption and personnel costs as well as noise and dust. Belt conveyors usually traverse a direct route, delivering materials much more quickly. They can be operated with significantly fewer per- sonnel. Depending on the project, belt conveying systems need up to 90% less primary energy than c omparable truck transportation, which reduces the operation's carbon footprint. Belt conveyors can overcome long distances, steep gradients and tight curves, and can be individually matched to the particular task and topography. Use is made of durable, tension-resistant conveyor belts. In doing so, Beumer uses various calculation programs to de- termine the optimum belt design. These enable tensile fo rces to be an- alyzed and also forces that occur due to acceleration and deceleration—always taking into account the intrinsic weight of the belt and the transported material. They are also used to determine pos- sible curve radii. Beumer can provide advance feasibility studies. In addition, the belt position is calculated in advance with the appropriate curve radius for the empty and loaded states. Wit h their slender lines, belt conveyors overcome broken terrain and other obstacles such as rivers, roads, buildings or rail tracks. Horizontal and vertical curves in the routing can also be overlapped. Depending on the requirement, Beumer offers open troughed belt conveyors for higher throughputs and larger mass flows Belt conveyors traverse a direct route and are much more competitive than truck transportation.
