Advantages of Gearless Motor Drives in Large Ore Grinding

Large capacity grinding mills are used for processing the ore. Using one large mill is more economical than using a number of smaller mills. This requires a very large capacity electric drive to rotate these mills. The mills themselves are large rotating cyclinders, ten to fifteen meters in diameter, grinding hundreds of tons of ore per hour.
