VDMA 37 2019 • VDMA MINING SUPPLEMENT Installation of the ABEL pump exceeded the expectation of the plant operator — shortening the filtration cycle by approximately 30 minutes, extending maintenance intervals of the centrifugal pumps, reducing consumption of stuffing box water causing dilution of the feed, significantly reducing noise in the pump station and most im- portantly, extraordinarily reducing energy consumption. In addition, the flocculated structure of the filtered material was no longer dis- mantled and a shorter filtration cycle allowed the plant to remove one centrifugal pump from operation saving money. Since startup in February 2013, the ABEL pump has operated reliably. Except for a routine scheduled oil change, the pump did not require any service or parts replacement, performing beyond the expectations of authorities. The total annual energy consumption has been reduced to ap- proximately 27,000 EUR/year. In addition, repair costs have been significantly reduced by roughly 7,000 EUR/year, due to the sub- stantially less demand on the remaining centrifugal pump. In total, costs were lowered by around 47,000 EUR/year. Moving the Big Things Based in Witten, Germany, ZF Industrieantriebe Witten GmbH has an unequalled, wide range of gearboxes for mining applications and large construction machines. Their drive, swing, winch and pump distribution gearboxes are extremely compact and combine precise machine control with highest power transmission. The ZF experts know exactly what is really needed to get the optimum performance from the machine. For stationary equipment, the next generation of gearboxes is smart. The new generation of ZF industrial drives is based on a new- ly created modular system. The latest portfolio comes up with an extremely compact and flexible design (increased power density of up to 40% per gearbox) with the advantage of reduced weight and size or elongation of working lifetime. The connectivity inside the industrial environment is one of the ZF Group's current advantages: the cloud-based Performance Man- agement System ZF ProVID enables a permanent Condition Monitor- ing of the complete drive systems. As a result, potential damage to gears and systems can be de- tected at an early stage, downtimes can be reduced by preventive maintenance measures, and thus significantly increasing the avail- ability of the complete system and reduce the total cost of ownership (TCO). The first systems have been installed in ropeway applications and this know-how is incorporated into the extension of the system to other industrial applications now. Keeping It Cool As mining and tunneling projects become more and more complex, the problems associated with climate control also become more of a challenge. Known as the experts for dust collection and ventilation in the mining and tunneling industries, for some time now CFT has also provides air-cooling solutions. The basis for this offering is the close cooperation with WAT Wärme-Austausch-Technik GmbH, like CFT, is also part of the CFH Group. CFT's product portfolio ranges from de-dusting systems for surface and underground operations through ventilation systems to mine air heating and cooling systems. Together, CFT and WAT have recently implemented international cooling projects which include both localized units up to 3 MW cooling capacity as well as main centralized systems each with a total capacity exceeding 30 MW. An ABEL HMD-G-50-0500 positive displacement pump improves filter press performance at a coal processing plant in Poland. CFT installed a ventilation system with integrated heating and cooling for the Slavkali shaft sinking project in Belarus.
