Oct 11, 2019 · Common terminology used for machinery vibration. . VERTICAL, HORIZONTAL). Velocity measurements and monitoring of vibration is the most common unit to identify various problems or acceptability such as: unbalance, misalignment, looseness (machinery structural, foundations, or bearings), harmonics, and many other issues in the machinery .
The vertical roller mill (VRM) is firmly established in cement plants all over the world. The biggest issues facing plants are not due to the equipment itself, but more to do with how well mill maintenance is understood and how the mill is looked after following commissioning.
With the exception of the atritta mills, pulverizers are designed such that the coal grinds against itself. Experience has shown that coal–biomass blends can be pulverized in atritta mills, but ball mills, bowl mills, and the large MPS (vertical spindle, tire-based) mills are not successful at pulverizing coal–biomass blends [12].
