Impact crusher, a new efficient crusher equipment, is popular because of its inexpensive price and great performance. But impact crusher will vibrate when it is working. Although vibration is inevitable when huge machine is operating and any machine may vibrate by the effect of power plants such as electromotor, vibration has different types. Slight vibration is considered normal reflection of operating machine, but if abnormal vibration especially the violent vibration appears, you should check the crusher to see whether there are some problems occur in the crusher or not. What cause the abnormal vibration on earth and how to solve the problem? Here we will let you know more details about the question.
Impact crusher crushes the materials with shock energy.
During the operation, rotor spins quickly under the drive of motor,
materials are crushed by the apron hammer when materials are conveyed to
the area of apron hammer. And then, the materials are threw to the
counter device and be crushed again. After that, the materials are
rebounded to the area of apron hammer from the impact plate to be
crushed again. This progress circle will continue over and over again.
There are many reasons that cause the vibration. For
example, the unbalanced rotor will cause abnormal vibration. So just
adjust the rotor will be fine. Also the over large materials may cause
abnormal vibration. At this time, you shocked measure the size of the
feeder entrance to make sure materials are not bigger than the standard
size. Abnormal vibration may appear with improper basic reasons, so the
problem will be dealt by fastening the foundation bolt. The abrasion may
change the weight of components that will cause abnormal vibration. So
the worn parts shall be changed and a new hammer is also needed. If the
rotation of the impact crusher or the cone crusher is too fast, we
should glue the main shaft bushing and the main shaft together, and then
the body and the main shaft will circle around the eccentric sleeve
which will avoid abnormal vibration.
Besides, there are other abnormal vibration causes and solutions. If the dear tip clearance is too small, the big and small wheel gears won't engage perfectly. So the addendum of the big and small wheel gears will intervene each other which will cause abnormal vibration. All you need to do is putting a gasket under the eccentric sleeve. If the transmission shaft bended, change a new one will solve the problem of abnormal vibration of the impact crusher. If the belt wheel of the crusher is quite unbalanced, you can clean the dust on the wheel to avoid abnormal vibration. Another cause of abnormal vibration is that the piled plate or the soil texture is unfit when the crusher is on the mobile car. So check the piled plate and the soil texture to ensure the place is suitable to the car.
