granulators may arise

① pellet mill bearings may be certain parts of the problem, so that the machine does not operate properly, the working current will fluctuate. Current high (down to check or replace the bearings).
② ring mold obstruction, or only a part of the die orifice discharge. Foreign objects into the ring mold,  machine for pellets , the pressure roller and the die gap is too tight, the pressure roller pressure roller bearing wear or damage can not turn will produce pellet mill vibration (check or replace the ring mold, adjust the nip).
③ coupling imbalance correction, down about biased, granulating opportunity vibration, and gear shaft seals are easily damaged (to the horizontal coupling must be school).
④ Spindle not tightened, especially D-or E-type machine, spindle loose will produce axial ran around,  oil processing , granulators much noise vibration, granulating difficulties (need to tighten the spindle tail butterfly springs and round nut). ⑤ size of gear wear, or replace a single gear, will produce noise (the need for run-time).
