Ball mills are a low-speed application (typical rotational speed is 10-20 RPM), where bearing damage can be challenging to detect. Condition monitoring of the ball mill began in December 2016 and right from the start, the readings indicated potential damage on the output main bearing. As the months passed, the readings remained at a fairly high but stable level, while the BPFO values showed an.
