Nov 07, 2021 In ore processing, grinding is an essential step for the overall performance of any mine. That is why the gearless drive of a grinding mill is one of the most crucial pieces of equipment in the concentrator and why it is subject to particularly high demands. Siemens has provided about 80 SIMINE Gearless mill drives to the mining industry since.
Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15 while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore grinding media and dropping it on.
Grinding is a crucial process step in ore processing – and for a mine’s overall performance. That’s why a grinding mill’s gearless drive is the crucial piece of equip-ment in the concentrator – and why it is subject to very rigorous demands. High availability and reliability throughout the entire lifecycle are a must, while unplanned.
Nov 11, 2021 Siemens supplied and commissioned direct-drive systems for belt conveyor and grinding mills located 4,200 meters above sea level. The motor size is not limited by the gearbox size, thus eliminating the need for multi-motor drives.
Bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. Building a track record ABB's experience in optimizing gearless solutions for grinding applications extends over 50 years, making it the market leader with the largest.
