Causes of severe vibration of mills and their solutions. Raymond Mill in Ezhou | Dali Raymond Mill's preferred Dawn Mobile Crushing Plant 1. Quality Imbalance The so-called unbalance is caused by the misalignment of mass and geometric centerlines. A fault condition. When the rotor rotates, its 'center of gravity' generates a centrifugal force acting on the bearing, and the magnitude of this force changes steadily with the rotation of the rotor. There are three types of imbalance: static imbalance or force imbalance, moment imbalance or even imbalance and imbalance. The appearance of the spectrum when unbalanced: the waveform is a sine wave; the trajectory of the axis is a circle or an ellipse;

1X frequency is dominant; Radial (horizontal and vertical) vibration dominates; Amplitude increases with increasing speed; The critical speed has a formant; The unbalanced horizontal and vertical axial vibration of the cantilever rotor is very large. In addition, eccentricity occurs if the center of rotation of the pulley, gear, bearing, or rotor deviates from the geometric centerline. 2. Misalignment The phenomenon of misalignment is common and very important because of the increased rotational forces it imposes on the bearings and seals. The types of misalignment are: parallel misalignment, misalignment, parallelism and misalignment.

Typical misalignment is mainly caused by the following reasons: imprecise assembly of the original parts, such as motors, pumps, etc.; the relative position between the original parts moved after installation; the distortion due to the pressure of the piping system; caused by the torque The flexible support is distorted and deformed; the machine deformation due to temperature changes; the coupling surface is not perpendicular to the axis; and the machine moves due to too much flexibility of the foundation when tightening the fixing bolt. In fact, most cases of misalignment are combinations of misalignment of axis angles and misalignment of parallelism.
