The situation of a variety of particle size vibrating at the same time is so complex that current study are basically under the conditions of the uniform particle size of materials.
(1) Where mvP∆ -the pressure drop in the vibrating fluidized bed, [ aP ]; oH - the material height before fluidization, [m]; oε - the materials voidage before Fluidization; sρ - Material true density, [ 3 / mkg ]; gρ - Gas density, [ 3 / mkg ]; 2k - Vibration energy transfer coefficient; Γ - Vibration intensity ( gA / 2 ω ); mfP∆ - the pressure drop of the ordinary fluidized bed, [ aP ].
The material thickness when sub-fluidized was about 160mm.
