Vibration Test and Shock Absorption of Coal

Because the vibration of the coal crusher chamber is very complicated, even if these two design countermeasures are adopted, the vibration problem still exists for the coal crusher chamber. Even when using the same design scheme and machine parameters, the vibration problem for the coal crusher chamber is more prominent in some power plants, whereas other vibrations are very small.

Vibration limit for coal crusher AMP

I would take baseline readings while the crusher is empty and another set while crushing. This will make it much easier to detect bearing failures. While crushing, the overall noise and vibration levels make it much more difficult to detect bearing failure. Setting the trip level at 200% of the baseline crushing level should allow you enough warning to investigate structural and internal failures. To detect bearing failures
