Chain Loop System Information
A Chain Loop System is a chain and paddle conveyor moving through a round housing. A loop system
allows you to do total loading and unloading with a single drive. Chain Loop Systems will handle a wide
range of free flowing materials. They are primarily intended for grain and grain products. They will move
material into and out of grain storage structures, vehicles, dryers and other facilities with ease and
gentleness. The Chain Loop System is well suited for blending materials while being transferred from one
storage unit to another.
The height and length of the system is limited by the combined horsepower required to move the grain.
The vertical Chain Loop System requires greater horsepower per foot, so the taller units will be more
limited in the overall horizontal length. System lengths of several hundred feet are common. However,
relatively small systems to accomplish more specific tasks are also available.
