Consequences of impact crusher rotor unbalance 1 When the impact crusher rotor is running in an unbalanced state it will produce a large inertia force and moment which can cause the unstable operation of the impact crusher equipment. More Detail; Causes of an Unbalanced Rotor IRD Balancing
How to Effectively Avoid the Imbalance of the …
Reasons for impact crusher rotor imbalance 1) The rotor itself has quality problems since the manufacturer does not make production strictly in accordance with standards; 2) Severe and uneven wear causes that the center and barycenter of the rotor body is not in the same position, resulting in the uncertainty of static balance and dynamic balance;
How to avoid rotor unbalance of impact …
The casting deviation of the rotor body and the mass deviation caused by the installation of the plate hammer will cause unbalanced centrifugal force when the rotor rotates.This centrifugal force causes the machine to produce forced vibration, leading to the failure of bearings and other parts, so the rotor of the impact crusher must be balanced.
