Why hammermill vibration

Hammermills can generate a lot of heat, being frictional machines, and any out-of-balance condition will cause vibration in the bearings. Despite the quality of couplings used today, there is always the possibility that heat from the hammermill will be transmitted to motor bearings, causing lubricants to prematurely deteriorate and evaporate
