The high-torque, low-speed mode of operation makes tubular drag conveyors more energy efficient than screw conveyors and pneumatic conveyors; often times requiring a fraction of the horsepower. Because material is effectively captured between flights, relatively static within the flight pocket throughout the travel, material is gently handled with a minimum of particle degradation. This mode of operation tends to enable these conveyors to better tolerate the effects of abrasion than screw conveyors and pneumatic conveyors.
Whereas tubular drag conveyors can include bends and change planes, they can do the work of several conveyors and thus have a lower cost. However, chain type tubular drag conveyors are a premium solution. They are robustly built for superb reliability in demanding industrial environments and any situation where uptime is critical. Chain-type tubular drag conveyors are the last choice for people whose primary concern is the purchase price. People who choose this method of conveying are first drawn to the technology because of its dust-tight construction, its ability to convey vertically, and through bends. However, the low energy consumption, and low wear and maintenance translate to a lower cost of ownership. When the lowest possible cost of owning a piece of equipment is most important, the best solution is the tubular drag conveyor.
