The American Davidson Coal Company needed a reliable system to move raw coal through tight plant spaces. Serpentix conveyors were installed to handle coal across multiple levels, navigating inclines and turns without interruption. This upgrade minimized material spillage and reduced maintenance downtime, resulting in smoother and more efficient coal handling operations.
Designed a 3D spiral conveyor to enable continuous recirculation and closed-loop testing
Enabled vertical lifts, horizontal turns, and controlled discharge with just one belt
Eliminated need for three conveyors + elevator system and multiple transfer points
Successful removal of 70–90% pyrite and nearly all shale pre-combustion
Cleaner coal combustion, reduced reliance on wet Flue Gas Desulfurization (FGD)
Lower costs, cleaner emissions, and feasibility of using high-sulfur coal
Set the stage for American Davidson’s commercial launch of dry separators
