1. The base strength and stiffness of the ball mill are not enough. Many cement plants have changed directly into a closed-circuit system by the open system in the technical transformation, and neglect the basis of the ball mill, thereby causing the ball mill body vibration. In this case, the cement plant can be solved by the basis of the reinforcing ball mill.
2. The installation accuracy is not high. If the homoelectric degree error of the motor and the speed reducer is large, the motor is connected to the gear unit, and the reducer is directly coupled to the ball mill upper cover, and the reducer vibrates, the ball mill body vibration is caused. The way to solve this problem is that the coupling bolts on the pine-ponce joints and the coupling bolts on the base. Move the motor, remove the couplers on the motor and the speed reducer, and then load a percentage on the speedometer input shaft, and the percent watch is on the timing axis, adjust the motor with a horn, and rotate the motor shaft head. Make the value on the percentage of no more than 0.8 mm, then install the coupling, tighten all bolts.
3. The rotor is unbalanced. The balance between the rotor is very affected by the vibration of the ball mill. In particular, the centrifugal ball mill is mostly used in large, small wind turbines. After a period of time, large, small wind wheel deformation, or the wind wheel blade wear is uneven, due to large wind wheel has a large direction, slightly unbalanced , The effort is large, causing vibration of the body. The method of solving is to adjust large, small wind wheel, if the effect is not obvious, can add weight on the wind wheel, the size and position of the weight can be determined according to the situation.
