Sep 10 2014 the comment in 1 that the mill continues to run because we know that the local detail failure poses no immediate danger to the mill due to fea studies and a history of mill straingaging instrumentation is not true the reason why we know that the mill has not failed is precisely because the mill has not failed
Jan 01 2011 the process of coal grinding in ball mills has been automated poorly because there were no methods to measure the main parameters of the grinding process such as quantity of coal in a mill grinding capacity and especially there were no methods to determine the prefailure condition in which the mill is so much overloaded with the material
Analysis of failure results shows that there are not many quality problems that belong to the bearings themselves most of which are caused by improper installation and use for this reason hightemperature bearings make a superficial review of common bearing failure modes and mechanisms in order to play a role of attracting a lot of attention
