Bed symmetry has been analysed in fountain confined conical spouted beds operating with fine particles. Thus, vertical particle velocities and the spout shape have determined a wide range of spouting air bed configurations. is widely accepted without draft tubes or nonporous ones, but this not case when open-sided are used. radial velocity profiles differ depending on cross-sectional angular pl...

Ammonium perchlorate particles have been dried in a laboratory spouted bed dryer (screen-bottomed type) which is categorized as a fluidized bed dryer. The solid particles obtained in this process of drying were semi-porous and known as the group D of Geldart classification. The variations of moisture content with resident time, the effects of bed height on the pressure dro...
