Abstract:The e ects of particle size (d p ) and super cial gas velocity (U g ) on the transport disengaging height (TDH) of iron ore particles were determined for a uidized bed (i.d.: 0.11 m; height: 2 m). The entrainment rates of iron ore particles in the size range 0.063-1.00 mm in the height direction of the bed were measured by using an isokinetic sampling probe, and they were used to determine the TDH for di erent values of d p and U g . The entrainment rate decreases exponentially with an increase in the freeboar… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
