PERFECCIONAMIENTOS EN LOS APARATOS DE TANSFERENCIA TERMICA.

摘要

A reaction vessel for making granular ferrite material from a stoichiometrically mixed solution of nitrates of the metals present in the ferrite molecular comprises a heatable container having overflow means for maintaining a bed of granular material in the container at a predetermined level, a mixing conveyor for the granular material which is wholly submerged in the granular material below this level, and a spray-feed device for distributing the mixed solution in droplet form over the surface of the bed of granular material.
