Three precautions for the body vibration of the ball mill

　　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, 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 motor and the velocity is large, the motor is connected to the gear with the gear unit, and the reducer is directly coupled to the ball mill, the reducer vibrates, causing the ball mill body vibration. The way to solve this problem is: The coupling bolts and motors on the pine-ponced 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 gear input shaft, the percentage table is on the timing shaft, adjust the motor with a horn, and rotate the motor shaft head. Make the value on the percentage of no more than 0.8mm, then install the coupling, tighten all bolts.

　　3. The rotor is unbalanced. The balance of the rotor is very affected to the vibration of the ball mill. In particular, the centrifugal ball mill is mostly used in a large, small wind wheel structure. After a period of time, large, small wind wheel deformation, or the wind wheel blade wear is uneven, due to the large diameter of the large wind wheel, slightly unbalanced , The effort is very large, causing vibration of the body. The method of solving is to adjust the large, small wind wheel, if the effect is not obvious, can add counterweight on the wind wheel, the size and position of the weight can be determined according to the situation.
