needed a proven electric drive technology that was reliable and had unique efficiency characteristics to help offset their increased operational power costs. GE proposed and sold six Quadramatic™ Drive Systems which includes a total of 12 low-speed synchronous motors to drive the mill through air clutches and pinions onto a common ring gear
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 ring-geared mill drive (RMD) technology to fit your site requirements. We provide optimized mill drive solutions for all types of ring-geared mills
V-BELT Ball Mill DRIVE V-belt or poly-V 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 assembly. V-belt drives allow use of
