Elutriation velocity
WebEntrainment rate of FCC particles had an exponential dependence on both freeboard height and superficial gas velocity.Size distribution analysis revealed that particle agglomeration occurred only in the dense bed.Neither segregation nor a reduction in particle size due to attrition and/or fragmentation took place. 展开 WebAn elutriation rotor combines two separation technologies, and each cell in the chamber is acted upon by the two opposing forces: Centrifugal force: Driving it away from the axis of rotation. This is the process of sedimentation under the influence of a centrifugal force field. Fluid velocity: Driving it toward the axis of rotation ...
