Aiming at rotating cone feeders used in annular spouted beds, the influence of spouting air velocity and the amount of hold-ups on particle mixing has been investigated.
针对环形喷动床采用旋转锥播料器对环形空间给料的方法，研究喷动风速和床上物料量对颗粒混合规律的影响。

Analysis of the particle velocity distribution and the gas-solid hydrodynamics indicate that the scale of inner particle circulation is crucial in determining the mixing pattern within the beds.
颗粒速度分布和气固流动特性分析显示，内部颗粒循环尺度是影响床内混合方式的重要因素。
