Mechanical Elements of tubes Mills For Cement industry The course include  Introduction -  Nature of wear in ball mills -  Influence on lifetime for wear parts - A- Influence from material to be ground  B- Influence from lining thickness  C- Influence from lining shapes and surfaces  The mechanical elements of a tube mill can roughly be subdivided into internal and external parts.  The mill internals have a direct function with regard to the grinding process and include principally the wear parts of a mill such as mill liners, diaphragms and grinding media. The external parts of a standard tube mill consist of mill shell, mill heads, mill bearings, feed and discharge equipment and include also the mill drive. In the following the external parts of the tube mill are described under special consideration of the process technological aspects. The mill internals are described in separate chapters. The feed devices have to fulfill the following functions Continuous flow of material into mil

Wear Parts & Wear resistant Material in ball mills

Wear Parts & Wear resistant Material in Mills   The equipment in the grinding installations therefore will have to be protected with sufficient wear resistant materials for two different reasons  In order to protec t the equipment from     damage and decay.- In order to maintain maximum output at optimum operating conditions-. Nature of Wear in Ball Mills Grinding in ball mills takes place by lifting the grinding media charge and the material to be ground followed by a return to the bottom part of the mill tube In this continuous cascading movement. The material quality of the wear parts in a ball mill must therefore partly be resistant to over hammering without cracking, and partly withstand abrasive wear.
