Deformation of the connecting shaft between the two excitersThere is required synchronization motion of two exciters if the shaft connecting the two exciters goes wrong, one of the exciters is work advanced or lags, will cause asynchronized vertical roller mill, thereby, the nonuniform force on the left and right sides do harm to the cross beam.
Check for deviation at both ends of the connecting shaft, adjust or replace the shaft.
The problem of exciter its ownShould better not use two exciters from two different suppliers, avoid the deviation problems of exciters its own.
Nonuniform feed, unbalance loadingUnbalance loading make the angle difference of two sides oversized, thus the cross beam wear and breaks prematurely.
Heavy impact force of feedingThe high drop of the feeding groove causes a heavy impact that damages the cross beam directly. meanwhile, the excessive impact force also brings about vertical roller mill which may have an influence on the performance.
