Dynaflow Drag Chain Conveyors The Dynaflow Tubular Drag Chain Conveyor is a mechanical drag conveyor system operating within the confines of a pipe. We call it the Problem Solver in a Pipe! Spiroflow’s Dynaflow® conveyors are structural mechanical drag chain conveyors operating within the confines of a pipe. In this conveyor, discs connected by articulated metal links (chains) move material within the pipe making it ideal for ultra-heavy-duty applications. The discs are made from a variety of materials including steel and cast iron. Dynaflow drag chain conveyors are suitable for applications with temperatures up to 420°F / 216°C. Features Ultra-heavy-duty conveying Gentle handling of fragile materials Maintain blends Totally enclosed for dust & contamination-free handling Layout versatility with 3 plane circuits Multiple inlets & multiple outlets Conveying capacities up to 10 ft3/min. / 0.28 m3/min. Convey straight-line lengths of up to 200 ft. / 60m per conveyor and link multiple conveyors for longer distances Low energy consumption
