Abstract
Description
Claims (10)
- 2. The invention of claim 1 wherein the step of separately conveying aggregates of dissimilar characteristics through a drying zone comprises moving the aggregates through the drying zone at rates which allow the aggregates to be dried to a predetermined moisture content.
- 3. The invention of claim 1 wherein the step of separately conveying the aggregates of dissimilar characteristics through a drying zone comprises controlling the volume of the aggregate being conveyed to control the quality of the bituminous mix.
- 4. In a method of preparing a bituminous mix of aggregates and bituminous liquid wherein aggregates of dissimilar size are dried and combined, the bituminous liquid is heated, and the aggregates and bituminous liquid are mixed together, the improvement therein comprising drying the aggregates before combining them.
- 5. Apparatus for preparing a bituminous mix comprising a multiple chamber storage bin for separately storing aggregates of different characteristics, a drying chamber, a plurality of conveying means communicating with the chambers of storage bin and arranged to separately convey aggregate from each of the chambers of the storage bin through the drying chamber, and mixing means arranged to receive the aggregates from the plurality of conveying means and mix bituminous liquid with the aggregates.
- 6. The invention of claim 5 wherein said plurality of conveying means comprise a plurality of wire belt conveyors each arranged to carry the aggregate through the heating chamber, and means for separately varying the bed thickness of the aggregate carried by each conveyor.
- 7. The invention of claim 5 wherein said plurality of conveying means comprise a plurality of wire belt conveyors each arranged to carry the aggregate through the drying chamber, and drive means for separately driving each of said conveyors.
- 8. The invention of claim 7 wherein said drying chamber comprises air heating means, blower means arranged to urge air in a downward direction through each of said wire belt conveyors, and damper means for regulating the flow of air through each of said wire belt conveyors.
- 9. The invention of claim 8 wherein said heating chamber includes duct means for recirculating the air through said wire belt conveyor.
- 10. The invention of claim 5 wherein said mixing means includes a rotatable tank for storing bituminous liquid and defining at least one opening in its upper portion, and means for rotating said tank to move its opening to a lower position and discharge its bituminous liquid through its opening.
- 11. The invention of claim 10 and further including weighing apparatus connected to said rotatable tank for determining the weight of the bituminous liquid in said rotatable tank.
