Gearless mill drives Grinding ABB
ABB’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 VBELT Ball Mill DRIVE Vbelt or polyV drives are generally used on grinding mills consuming 350 HP or less Where power exceeds this, drives become so large and motors become special, resulting in an uneconomical application Generally the driven mill sheave is of split hub construction to facilitate field assemblyBall Mill Drives Mineral Processing Metallurgy drive system Standardization Allows for single line application with identical QdX4TM Mill Drive units installed in both 40’ SAG and 28’ Ball mills This allows for complete interchangeability, Economic value Overall cost savings • Foundation design requirements are very similar to dual pinion drive mills QdX4TM Mill Drive system
Autogenous and SemiAutogenous Mills
introduced into the large mill feed chutes And the product of the large AG/SAG grinding is either a finished size ready of processing, or an immediate size for further grinding in a ball mill, pebble mill, VERTIMILL® or a stirred media detritor (SMD) Testing of the ore It is essential that the ore be tested to determine its amenability to the requirements The optimal drive type can only be selected after determining the mill size, the need for variable speed and the characteristics of the electrical system of the plant Comparison of Drives Systems for Grinding Applications The question what drive system is optimal for SAG and ball TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS MILL Nowadays more and more mills are fed by frequency converter systems, allowing for higher performance and flexibility of operation ABB continuously extends technical and performance frontiers of ringgeared mill drive (RMD) Ringgeared mill drives Grinding ABB

Ball mill Wikipedia
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shellBoth the SAG mill as well as the ball mill will be powered by gearless drive systems; they will benefit from the world's most energy efficient drive solution ABB's gearless mill drive systems are designed and engineered from the bottom up to deliver massive capacity, superior energy efficiency, unmatched availability and global gearless ball mill driveDual drive ball mill ge dual pinion mill drive solutions For the expanded grinding operations ABB will deliver five dual pinion 2 x 9MW lowspeed mill drive systems for two 36foot semiautogenous SAG and three 26foot ball mills and one dual pinion 2 x lowspeed drive system for a regrind mill Details; Technical Name Of Pinion Of Ball Mill DriveGe Dual Pinion Mill Drive Solutions
