Selecting a tubular drag conveyor
The enclosed conveying provided by a tubular drag conveyor makes the conveyor ideal for transporting dusty material or material that's easily contaminated. The conveyor's small size and versatility also make it suitable for applications with only limited floor space. This article describes tubular drag conveyor basics, including how the conveyor works, its applications, and its advantages and disadvantages. Final sections explain how to select a conveyor for your application, including selecting the chain, flights, and construction materials, and estimating the conveyor size and chain speed.
Like many other mechanical conveyors, a tubular drag conveyor transfers fine, flowable bulk materials from one point to another. What makes the tubular drag conveyor different from other conveyors, however, is that it uses a moving chain to transfer the material through a totally enclosed casing at any angle, in any plane, and around obstacles.
