Mining of ore has become technology drivenoperation today. The mined ore needs to be processed atsite so that further operations are convenient and costeffective and high volumes are processed. Grinding of oreis one of the most important and power intensive operationin mining. In order to process the ore at faster rate, sizes ofmills have gone bigger and bigger. While mill diametershave touched 42 feet, at the same time power required hasgone upto 38 MW per system. Because of huge processingrequirements, mills have migrated from geared to gearlessand accordingly changes in mechanical systems, drivemotors and power converter technologies have thrown abigger challenge. Scaling up the equipment also has majorrequirement of robust mechanical design to reducemaintenance and ensure reliable operation.This paper focuses on overview of various grindingsystems, drive and converter technologies and other aspectslike design, operation and maintenance. Comprehensiveliterature survey conducted and systems which are beingused today are compared with respect to cost, efficiencyand drawbacks. Also possible advanced technologies withrespect to improvement in Drive is also suggested.
