VDMA 72 VDMA MINING SUPPLEMENT • 2017 Mining Forum in Berlin (June 1-2, 2017). More information on the 2017 Mining Forum is available online at Vision for Process Automation Based in Aalen, Baden-Württemberg hema designs customer-spe- cific camera systems for a wide range of applications. Automated processes and equipment warning systems depend on reliable vision systems, and with that in mind, hema electronic has designed the seelectorICAM HO1 camera system for the mining industry. A robust design, high dynamic range and superior quality video were integrat- ed during the development. An ethernet interface allows the digital camera to be easily installed in digital networks. A unique feature of the seelectorICAM HO1 is the high-dynamic range video imaging. A more than 120-dB dynamic range combined with a high-quality color image of 1.3 megapixel exceeds what is available in existing systems. The plant manager or equipment oper- ator can now see and detect people and obstacles next to floodlights even in dark areas. Reliable detection has taken on an added importance as more mining operations consider autonomous operations. With this type of camera installed, remotely operating machines and the use of unmanned aerial vehicles (UAVs) is within reach. Not only for proof of concept, but also for safety and security in deep mining operations. All the systems already in use could benefit from these camera options. The robust electronics and the IP67 housing ensure a safe op- eration. The reliable optics and cabling complete the system. The camera adapts easily to existing digital networks using standardized digital interfaces such as Ethernet or wireless connections. The new camera has been tested on construction machines. It was used in rear-view camera applications on excavators and wheel loaders. The results show the exquisite image quali- ty. The system was then tested on rear-view mirror applications. Operators reported good results even at sunset. Now hema hopes to test the seelectorICAM HO1 in mining and material handling applications. These modern cameras with HDR sensor technology could add another layer of safety and security to exist- ing operations. Linear Booster Drives for Conveyors Last year, the Prosper-Haniel coal mine installed a TT Drive on its H2 belt conveyor without interrupting operations, achieving a com- prehensive solution. A subsequent installation of another TT Drive resulted in further cost reductions for the mining company. Owned by RAG Deutsche Steinkohle, Prosper-Haniel produces about 3 million metric tons (mt) of coal per year. The H2 conveyor transports raw coal 1,270 m with a lift of 186 vertical m. Its operating speed amounts to 3.2 m/s with a capacity of 2,000 mt/h. With the installation of the first TT Drive, Voith made it possible for the Prosper-Haniel mine to carry on using a heavily damaged steel cord belt (ST5000) until the next scheduled downtime and prevented an un- planned shutdown and corresponding production loss. During the next downtime, Voith installed a second TT Drive in the H2 conveyor. This reduced more belt tension and Prosper-Haniel has since been able to operate the conveyor with a cost-saving fabric belt (PVG2000/1). Project managers Ralf Dohle and Wolfgang Kosiuk from RAG Deutsche Steinkohle are completely satisfied with the booster drives and the project execution. "Voith's solution has provided us with a dual benefit," Dohle said. "Not only did we manage to avoid an unplanned shutdown because of the damaged belt, we are now able to use a textile belt instead of an expensive steel cord belt for the system." The Voith TurboBelt TT Linear Booster Drive is a high-perfor- mance secondary drive for belt conveyors. It extends the use of belts in existing systems and increases their available power. In new belt conveyor systems, it reduces the requirements on belt quality, leading to considerable cost savings. Dynamic Weighing Systems When it comes to mobile weighing systems, Pfreundt continues to improve its product line for wheel loaders, and they have some great ideas for mining applications as well. The company is one of the lead- ing international producers of integrated weighing systems with 40 agencies worldwide. The actual weighing system WK60 has been available for about two years now. "Improvements in technology and materials have al- lowed us to develop the WK60 and the user interface looks a lot like an iPad, except that it's 6-cm thick," said Bruno Reckmann, direc- tor of sales and marketing for Pfreundt. The back of the device is equipped with a plug-and-play connection simplifying the installation. "A technician needs to calibrate the system, but it's relatively simple hema has designed a robust camera for mining operations. The DMT Pilot 3-D navigates without GPS.
