Method Of And Apparatus For The Mixing And Processing Of Fragile Material And Fragmentel Solids
US Patent:
4475987, Oct 9, 1984
Filed:
Dec 29, 1982
Appl. No.:
6/454329
Inventors:
Frank Forbes - Lakewood CO
Assignee:
Dravo Corporation - Pittsburgh PA
International Classification:
C10B 106, C10B 3106, C10B 5306, C10B 5308
US Classification:
202 99
Abstract:
Fragile agglomerates with crushed rock fragments, such as fines which are subsequently agglomerated and which result in the crushing of rock fragments, such as oil shale prepared for retorting are mixed and delivered onto conveying means, such as a travelling grate by charging the rock fragments into a bin which delivers through a choke-feed onto the conveyor or travelling grate by introducing the agglomerates through a series of space conduits or tubes terminating inside the bin below the level of the lump material or fragments in the bin where the rock fragments have a downward travel such as to enable the aggregates to diffuse from the ends of the spaced pipes into and through the fragments and while so separated and diffused through the fragments move with the fragments onto the grate.
Method Of And Apparatus For The Mixing And Processing Of Fragile Material And Fragmented Solids
US Patent:
4381989, May 3, 1983
Filed:
Nov 19, 1981
Appl. No.:
6/322771
Inventors:
Frank Forbes - Lakewood CO
Assignee:
Dravo Corporation - Pittsburgh PA
International Classification:
C10B 5306, C10B 3700
US Classification:
208 11R
Abstract:
Fragile agglomerates with crushed rock fragments, such as fines which are subsequently agglomerated and which result in the crushing of rock fragments, such as oil shale prepared for retorting are mixed and delivered onto conveying means, such as a travelling grate by charging the rock fragments into a bin which delivers through a choke-feed onto the conveyor or travelling grate by introducing the agglomerates through a series of space conducts or tubes terminating inside the bin below the level of the lump material or fragments in the bin where the rock fragments have a downward travel such as to enable the aggregates to defuse from the ends of the spaced pipes into and through the fragments and while so separated and diffused through the fragments move with the fragments onto the grate.
Fine Particulate Removal From Oil Shale On A Travelling Grate Retort
US Patent:
4381988, May 3, 1983
Filed:
Jul 20, 1981
Appl. No.:
6/285060
Inventors:
Daniel W. Kestner - Coraopolis PA
Frank Forbes - Lakewood CO
Frank Forbes - Lakewood CO
Assignee:
Dravo Corporation - Pittsburgh PA
International Classification:
C10G 100, C10B 4906, C10B 5306
US Classification:
208 11R
Abstract:
In a process for the removal of fines from a bed of oil bearing shale in a travelling grate retort, a fluid such as air, inert gas or process gas is drafted through the bed in order to entrain in the fluid substantially all of the fines in the bed. The fines are then evacuated from the bed thus increasing the permeability of the bed and substantially decreasing the fines in the retorted shale oil.
