Container, device and method for storing or processing particulate materials to minimize or eliminate vibrations such as quaking or shaking

A method of processing granular material particles in a container,

• wherein the container comprises:
• an upper part,
• a lower discharge part, wherein the lower discharge part is non-rotating, tapered and has an inner wall converging to a discharge outlet of the container, and
• a baffle placed in the lower discharge part, the baffle having a projecting surface, which projects into the interior of the container, and an opening,
• wherein the method comprises:
• flowing the granular material particles downwards in the container, and
• discharging the granular material particles through the discharge outlet,
• wherein flowing the granular material particles downwards in the container comprises:
• stopping the downward flow of a portion of granular material particles proximate and in contact with the inner wall of the lower discharge part, wherein said portion of granular material particles proximate and in contact with said inner wall rests on said projecting surface forming a stagnant zone above the baffle,
• flowing another portion of the granular material particles not proximate to said inner wall through the opening of the baffle to a lower portion of the container or to a discharge conduit connected to said discharge outlet.

A method of processing granular material particles in a DRI reactor, wherein the DRI reactor comprises a container having:

• an upper part,
• a lower discharge part, wherein the lower discharge part is non-rotating, tapered and has an inner wall converging to a discharge outlet of the container, and
• a baffle placed in the lower discharge part, the baffle having a projecting surface, which projects into the interior of the container, and an opening,
• wherein the method comprises:
• flowing the granular material particles downwards in the container, said granular material particles including iron particles,
• circulating in the container a reducing gas at high temperature, in the range from 850° C. to 1100° C., to form granular material particles of direct reduced iron (DRI), and
• discharging the granular material particles through the discharge outlet,
• wherein the flowing the granular material particles downwards in the container comprises:
• stopping the downward flow of a portion of granular material particles proximate and in contact with the inner wall of the lower discharge part, wherein said portion of granular material particles proximate and in contact with said inner wall rests on said projecting surface forming a stagnant zone above the baffle, and
• flowing another portion of the granular material particles not proximate to said inner wall through the opening of the baffle to a lower portion of the container or to a discharge conduit connected to said discharge outlet.

A method of processing granular material particles in a DRI cooler, wherein the DRI cooler comprises a container having:

• an upper part,
• a lower discharge part, wherein the lower discharge part is non-rotating, tapered and has an inner wall converging to a discharge outlet of the container, and
• a baffle placed in the lower discharge part, the baffle having a projecting surface which projects into the interior of the container and an opening, wherein the method comprises:
• flowing the granular material particles downwards in the container, said granular material particles containing direct reduced iron (DRI),
• cooling the granular material particles by contact with a cooling gas circulating counter-currently to the downward flow of said granular material particles, and
• discharging the granular material particles through the discharge outlet, wherein the flowing the granular material particles downwards in the container comprises:
• stopping the downward flow of a portion of granular material particles proximate and in contact with the inner wall of the lower discharge part, wherein said portion of granular material particles proximate and in contact with said inner wall rests on said projecting surface forming a stagnant zone above the baffle, and
• flowing another portion of the granular material particles not proximate to said inner wall through the opening of the baffle to a lower portion of the container or to a discharge conduit connected to said discharge outlet.
