Abstract
Grinding mill drives play an important role in the mining industry. Close to 60 % of the electrical energy consumed by modern concentrator plants goes to grinding mill drives. Different technologies are used in grinding systems presenting special characteristics from the electrical and process points of view. This paper presents a technical evaluation and practical experience of two different technologies used in high power grinding mill drives. The analysis is focused on the static power converter and associated control scheme required to drive the motor. Cycloconverters and load commutated inverters are analyzed in terms of the interaction with the power grid, the motor, and the required control scheme. The evaluation is supported with practical results obtained in different concentrator plant facilities.
