Problem-solver in a pipeline: The versatile tubular chain drag conveyor

Enclosed conveying handily meets the strict hygiene and worker health and safety standards for conveying chemicals, foods, and other dry bulk solids. This article explains how the tubular drag chain conveyor meets these and other tough conveying requirements in a range of industries.

A tubular chain drag conveyor (also called a tubular drag conveyor or tubular link-chain drag conveyor) uses a moving chain assembly consisting of an endless chain mounted with disc-shaped flights to transfer material through a totally enclosed casing at any angle, in any plane, and around obstacles. This operating mode is ideal for powders, granules, pellets, flakes, and any other finely divided, flowable dry bulk material. The conveyor's wide range of available designs and construction materials allows the unit to handle not only chemicals and foods, but materials in industries such as cement, minerals, glass, brick-making, and waste-water treatment.
