Abstract: Separation of a high temperature (e.g., 300.degree.-1200.degree.

The possibility of fluidization of the solids is minimized by causing the velocity of the gas component of the solids-gas stream to be reduced during, or just prior to, introduction of the gas into the packed bed of solids, e.g., by providing an expanding conical end to the inlet for the solids-gas stream into the vessel. A gas permeable solids impermeable element may also or alternatively be connected to the inlet and extend toward (optionally all the way to) the side wall of the vessel, to substantially prevent fluidization.

Abstract: Ultrafine powder is stored in a pneumatic transportation tank (20), and is discharged to a transporting conduit (23) while being fluidized by the pressurized air fed through a fluidizing air port (24). The ultrafine powder is fed to a weigher (30) provided at the other end of the transporting conduit (23), at which the weight of the transported ultrafine powder is weighed by a load cell (31). After the weighed value reaches 90% of a predetermined value, the fed amount of the pneumatic transportation air is reduced, and a bypass regulating valve (38) is adjusted to thus decelerate the transportation. When the weighed value reaches 100% of the predetermined value, the discharge of the ultrafine powder to the transporting conduit (23) is stopped. This method and the apparatus enable the storage, quantitative batch transportation, and automatic weighing of the ultrafine powder such as silica fume.
