When designing a way to move bulk material that is more severe than what most aggregate operations see, a Georgia company opted for belt bucket elevators and variable-speed belt conveyors. This system allows Carbo Ceramics to process two different products at its three-year-old plant. Carbo Ceramics, based in McIntyre, Ga., is the world's leading producer of ceramic proppants, which are high-strength spherical pellets used in the hydraulic fracturing of natural gas and oil wells. In the process, large volumes of proppant are mixed with a highly viscous fluid to form a slurry.
