This paper presented a new method for producing grinding media for ball mills, based on the cross wedge rolling technique. It is a medium-throughput technique, i.e., its throughput is higher than in die forging but lower than in skew rolling. The paper investigates typical failure modes which may occur during the rolling process.

Flat die pellet mills feature a flat die with small holes through which the material is forced under pressure, forming cylindrical pellets. Ring die pellet mills, on the other hand, utilize a rotating die with larger holes, …

In [1], Svalbonas reviews the states-of-the-art in the design of grinding mills and ring-motors (for gearless drives). He concludes that failures in ring motors occurred …

Typical bearing failure cases are discussed. According to statistical results, wear and fatigue are the most common failure modes of bearings, as bearings are affected by cyclic loads, friction, and lubrication during operation. Incorrect assembly, use, and maintenance is the main causes of bearing failure.

This work investigates the failure data analysis of steel rolling mill used for producing Thermo Mechanically Treated (TMT) rod. Initially, a cost model is developed to analyze the failure costs and thereby quality tools such as brainstorming and Fault Tree Analysis (FTA) is used to identify the root cause of the breakdowns and alternative technical solutions to …

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. Svalbonas [2] presents strain gauge measurements from a mill in a paper dated 1979.
