ABSTRACT:
In an automation system for a mixing and dispensing apparatus, different colors of granite granules are placed into different silos. Dampers and proportion gates on the bottom of the silos permit specific proportions of different granite colors to fall and mix on a conveyor. The granite color combination is transported through a bucket elevator to a lazy susan and from the lazy susan into a selected bin. A second combination of granite colors is then mixed by adjusting selected proportion gates and opening and closing selected dampers. The second color combination is transferred through the lazy susan to a second selected bin. Any number of color combinations can be made and transferred to selected bins. The granite color combinations from the several bins are then applied to an asphalt-coated fiberglass mat through a dispensing apparatus on the bottom of the selected bins. The entire process is automated and controlled through logic circuitry.
