Abstract
An asphaltic mix storage system has an improved conveying apparatus including a housing which is upwardly inclined from the horizontal so as to extend from approximately ground level to the top of a storage container. The conveying apparatus also includes a drag-type conveyor in the housing comprising an endless conveyor chain having spaced apart conveying blades carried thereby with the lower edges of the conveying blades in sliding engagement with the lower wall of the housing. The forward faces of the conveying blades and the lower wall of the housing define an acute angle therebetween to prevent carryover of asphaltic mix beyond the discharge chute at the upper end of the apparatus.
