Finally a method for fault diagnosis of HP mill based on Gaussian regression ...


Causes and solutions of vibration of medium speed coal mill. Chinese and Foreign Entrepreneurs, (3): 171-172.[2] Zhu X Y, Yang J N, 2007. Common failure analysis and spot inspection management of medium speed coal mill. Machinery Design & Manufacture, (5): 202-204. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed decreases with mill size and remains constant for a given mill diameter.
