“…More recently, vibrated fluidized bed (VFB) and pulsation fluidized bed (PFB), which can strengthen the movement of particles, increase gas-solid contact rate, improve fluidization quality, and achieve fluidization of fine cohesive particles are applied for coal cleaning [ 202 , 203 ]. Vibrated dense medium fluidized bed (VDMFB) [ [203] , [204] , [205] , [206] ], gas-vibro fluidized bed (GVFB) [ 197 , 207 , 208 ], and pulsating air dense medium fluidized bed (PADMFB) [ 202 , 209 , 210 ] are the examples of these technologies. In these types of ADMFB, vibration energy weakened the influence of bubble that occurred in conventional ADMFB since the fluidization stability could flexibly adjust by the pulsating airflow [ 204 , 205 ].…”
