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.
