Choosing the Right Motors for your Mills Slide presentation providing an overview of the process for selection motors for grinding mills Motors are selected based on "mill overload" conditions that are more rigorous than the mill process conditions Motors are rated as one of four “design types” for their ability to endure the heat of that starting and pull up In ascending order of their ability to start inertial loads, NEMA designates these as design type A, B, C, and D Type B is the industry standard and is a good choice for most commercial and industrial applications5 Steps To Choose Best Motor For Your Application SAG Mill SemiAutogenous Grinding Mill The power to spin the mill comes from large electric motors coupled to mill shell through a clutch and gear system These electricity consumed by these motors is the largest cost and inefficiency Most SAG Mill SemiAutogenous Grinding Mill the first GMD for a doublerotating ball mill in Carlin, Nevada, meeting a 160 °C heat challenge at the mill shell GMDs have now been supplied for the world's largest autogenous (AG), semiautogenous (SAG) and ball mills, fulfilling the highest power requirements while operating under extreme environmental conditions Focus on the futureGearless mill drives libraryeabbABB’s GMD is the most powerful mill drive system in the market to power semiautogenous (SAG), ball and autogenous (AG) mills, This ’workhorse’ for grinding operations combines a robust, servicefriendly and fit for purpose design to provide highest throughput, reliability Gearless mill drives Grinding ABB

SAG mill system diagnosis using multivariate process
In tumbling mills, the mill shell is rotated, and motion is imparted to the charge via the mill shell The grinding medium may be steel rods, balls, or rock itself The most common operational adjustment made to try to compensate for this declining lift is to increase the mill speed (for those mills which have variable speed motors) The other principle control is to adjust the fill level by changing the rock feed rate In 3 Generic SAG mill geometry and ScienceDirectThe two SAG mills in the Mission South Mill each have two 3 000 horsepower electric motors They can rotate in either direction which helps even out the wear on the steel liners inside the mill When the rocks are about 3/8inch or smaller they are fed as a slurry into the two ball mills Each ball mill is turned by a single 3 000 horsepowerMill Dual Motor Sag Mills dewaeleetfilsbe
