It is indicated that the vibration energy cannot effectively inhibit the bubble evolution, resulting in irregular dissipation of vibration energy and disordered movement of particles, which is not conducive to the separation of fine coal. When A = 2 mm, f = 25 Hz, Uv = 11 cm/s, the decrease of Rp-v is the lowest.
