If vibration is found, stop grinding quickly and take out the foreign bodies; When the sudden vibration of the vertical roller mill suddenly intensifies, accompanied by harsh noise, and the current rapidly increases to an infinite value, it indicates that the transmission gear or bearing of the vertical roller mill is damaged.  It is necessary to shut down and take out foreign matters, replace new steel balls, replace grinding rings, and replace damaged transmission gears or bearings.  The above content only analyzes the vertical roller mill fault from the three aspects of sound, amplitude and temperature, and puts forward the corresponding solutions.  The vertical roller mill is far more than these problems in actual operation, so the vertical roller mill fault can quickly help you find and solve problems.
