Influences of vibration form on the grinding ...

1972-11-1  After grinding tests of coal particles in a batch, vertically vibrating mill under such three different vibration forms as sine, deformed square and pulse, grinding by the use of the deformed square vibration was found to be most efficient if the required waveform can be obtained without great difficulties, granted that the energy requirements are greater than for ordinary sine vibration.

Vibration characteristics of an operating ball mill ...

2019-7-25  Abstract. A ball mill, which is used to finely grind materials, causes high levels of vibration and sound during grinding operations. The vibration and sound of mills provide significant information about the internal conditions and can be used to estimate the status of the ground material. We developed a simulation model for the vibration of a ...
