This alumina refinery creates a high volume of sodium oxalate by-product through the refining of bauxite for the production of alumina.
This substance is extremely sticky and difficult to transport as it sticks to belts, shafts, and vertical surfaces as it gradually solidifies. The best solution for this very difficult problem has been found to be SPIRAC shaftless spiral conveyors. Offering little in the way of idle surfaces to stick to, the shaftless screw works through any buildup or solidifications to keep the material moving. High torque and high fill rates ensure a robust and reliable operation.
