towards larger-sized SAG mills with diameters of 10.4 m (34 ft) and above, with the largest being 12.2 m (40 ft) in diameter and drawing 20 to 22 MW (Jones, 2006). Mill liners provide the replaceable wear-resistant surface within grinding mills; they also impart the grind-ing action to the mill charge, and at the discharge end, remove theFailure is not an option Extended warranties for grinding mills. Grinding mill’s largest components are critical assets where the impact of failure is high. When failure is not an option, extended warranties from the grinding mill OEM can ensure longevity of the part’s lifecycle.

It would be unreasonable to dismiss the viewpoint of a mill designer on the design of ring motors just because the mill structure is relatively much simpler than the motor. So, let us look at the design validation of mills.

As one of the machines widely used in mining, a semi-autogenous grinding (SAG) mill can significantly improve the roughing efficiency of rock. But the SAG mill still faces the obstacles of significant energy consumption and empirical operation parameters. In order to obtain the optimal operation parameters of a SAG mill, in this paper, the SAG Mill (Semi-autogenous Grinding) Quantity : 1 unit Composed of a twelve-pulse cycloconverter together with a synchronous ringmotor Power : 26.000 HP Voltage : 4950 V addition, it does not need any gear box and ring gear and therefore eliminates mechanical wear and the related problems and maintenance. It is a drive Gearless Mill Drive Protection Improvements and Its

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills.

The wear and failure analysis of shell liners of a grinding mill is investigated. Metallurgical and tribological studies were conducted on the worn liner of a semi-autogenous grinding mill in Chadormalu Industrial Complex. The chemical analysis, wear mechanism, microstructural variations and mechanical properties in different Mill operators face the twin challenge of increasing production to meet demand for commodities and declining ore grades. Marcelo Perrucci, Global Product Line Manager, Grinding, ABB, explains why gearless mill drives (GMDs) are increasingly becoming the solution of choice for high-capacity mills.
