Finding failure - International Cement Review

Roller presses grind raw materials and cement in a cost-efficient way. However, the highly dynamic process causes excessive stress on the bearings of the grinding rolls and the two drive trains, which ultimately fail and lead to unplanned stoppages. An online condition monitoring system that uses acceleration sensors can help avoid such stoppages.
