The 152-m primary conveyor, broken down into four sec- tions, went first. The rock crusher fol- lowed, with a total travel time of less than two hours. The entire operation was completed on schedule and with zero incidents, despite the weather, Mammoet reported. The crusher was active until just hours before the move, which signifi- cantly reduced downtime. The quarry dates back to 1900. With the crusher moved, another 100 years of operation is expected. New Drives Enhanced Control for DC Installations ABB's new series of DC variable speed drives (VSDs) allow users with a large installed base to get better perfor- mance from their existing systems. With the new DCS880 VSDs, miners who are heavily invested in a DC sys- tem have the option to continue us- ing DC technology while better align- ing with modern AC advancements. The DC VSDs are built on ABB's all-compatible, common-drive plat- form, sharing the same control pan- el, features and tools as recent- and future-generation ABB drives. Once users have learned one ABB all-com- patible drive, they can easily use other all-compatible drives — both DC and AC, according to the system developer. They also integrate with ABB's Abil- ity monitoring services — a digital of- fering, which provides real-time data about drive status and performance from any location. Monitoring param- eters include drive availability, envi- ronmental conditions and fault events. Optimized for safety, simplicity, and user-friendliness, the drives fea- ture built-in functions, such as safe torque off (STO), which prevents un- expected startup of machinery. This protects people and equipment by reducing risk during operation. DCS880 drives have the flexibility to meet the precise needs of a broad range of industrial environments and applications with superior speed and torque control in a compact, space-saving design that easily fits into electrical control rooms. They can handle advanced programming with standard IEC languages and in- clude many ready-made, dedicated application programs.
