Study on shock vibration analysis and foundation reinforcement of large ball mill

The vibration of the ball mill foundation will seriously affect the operation stability of the ball mill. According to the connection relationship between the ball mill and the foundation, the mill-foundation transient shock model is established. The effects of shock force, concrete grade and shock...

description The vibration of the ball mill foundation will seriously affect the operation stability of the ball mill. According to the connection relationship between the ball mill and the foundation, the mill-foundation transient shock model is established. The effects of shock force, concrete grade and shock angle on the transient response of the foundation were studied. And based on the problem of the mill foundation, the reinforcement scheme of the foundation was put forward. The following conclusions are drawn: with the increase of shock force and shock angle, the displacement of foundation joints increases, and the maximum stress also increases; concrete grade has little effect on foundation stability; after the foundation reinforcement scheme is used, the vibration caused by the shock of the ball mill is effectively reduced, and the stability of the foundation is increased. Finally, the correctness of the model and the scheme is verified through the comparison with the test data. The calculation results provide a reference for the improvement of the ball mill foundation.
