Mine improves output with SINAMICS PERFECT HARMONY
When a major copper and molybdenum mine needed to improve the process and throughput for various applications within its multimillion-dollar expansion, it called in Siemens to help with its optimization efforts.
Only SINAMICS PERFECT HARMONY variable frequency drives (VFDs) were able to meet the three critical criteria for the mine’s ball mill applications: sufficient starting torque, clean operation over a wide range of speeds, and improved uptime and availability. Together, the drives’ variable speed capability and Advanced Cell Bypass technology allowed the mine to maximize throughput while maintaining motor efficiency.
After installing the VFD on their ball mill applications, the mine owners saw such improvement in their process — and profits! — that they went on to install the drive on three additional applications as well. They expect these updates to yield similarly high levels of uptime and throughput.
