Drag and Flight Conveyors

Drag conveyors are well suited where multiple loading or discharge points are required, such as several silos in line, and also when a totally enclosed conveyor is needed for dust containment. They are capable of handling fine materials ranging from dust to 6 inch (150 mm) lumps. Flight Conveyors have one, or usually two strands of chain which move a "mass" of bulk material through a trough or enclosed casing (casings can be steel, concrete, or other materials). They are used where capacity requirements are fairly high, 200 - 400 TPH and when the material is somewhat fluid. The typical materials conveyed are TSP (fertilizer), raw meal, and finish cement.
