SAG mill Synchronous motor drive with air clutch Milling - Energy intensive and high maintenance 2018-05-09 converter based drive systems provide benefits that improve the ball mill operation FIXED SPEED CONFIGURATIONS The key issue to operate a mill in a fix speed mode is the starting A squirrel-cage motor or a synchronous motor started ....
Effect of Load on a Synchronous Motor A synchronous motor runs at constant synchronous speed, regardless of the load Let us see the effect of the load change on the motor Consider a synchronous motor operating initially with a leading power factor The ,...
Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor...

Abstract: Typical drive configurations of high-capacity SAG mills use a two-stator-winding vector-controlled synchronous motor, with a 30° shift between the two windings, fed by a two-secondary delta-delta-wye power transformer and two six-pulse cycloconverters This paper presents and evaluates three different modeling options for the SAG mill drive...
SAG Mill Grinding Circuit Design , (also called wrap-around motor or ring motor) is a very large synchronous motor The poles of the motor are directly installed on a pole flange on the mill shell: this means the mill body becomes the rotor The stator of the...
A SAG mill is usually a primary or first stage grinder SAG mills use a ball charge of 8 to 21% The largest SAG mill is 42'' (128m) in diameter, powered by a 28 MW (38,000 HP) motor A SAG mill with a 44'' (134m) diameter and a power of 35 MW (47,000 HP) has been designed Attrition between grinding balls and ore particles causes grinding of...
