ABSTRACT:
A method of continuously feeding solid particles into a pressurized container which comprises the steps of confining a body of liquid having a specific gravity less than the specific gravity of the particles in proximity to the pressurized container, maintaining communication of the pressure conditions within the pressurized container with a free surface of the confined body of liquid so as to maintain the body of liquid under pressure, continuously introducing a supply of solid particles entrained in liquid under pressure into the body of liquid under pressure, causing the entrained particles introduced into the body of liquid to continuously move toward the bottom portion thereof, mechanically continuously moving the particles in the bottom portion of the body of liquid upwardly along a confined path which extends from a position adjacent the bottom portion of the body of liquid upwardly above the level of the aforesaid free surface thereof to a feed position in pressure communication with the interior of the pressurized container from which the particles can be fed into the pressurized container, allowing the entraining liquid filling the spaces between the solid particles being moved upwardly to drain from the particles downwardly into the body of liquid, continuously withdrawing liquid from the body of liquid at a level at or near the free surface thereof in an amount so related to the amount of particles and entrained liquid introduced thereto and particles removed thereby along the path sufficient to maintain the free surface at a substantially constant level and along a liquid withdrawal flow path arrangement devoid of restrictions of a size less than that necessary to permit free passage thereby of any fine particles entrained in the withdrawn liquid and apparatus for practicing the method.
