The document highlights important tradeoffs, such as reduced working loads and speed limitations for stainless steels compared to heat-treated carbon steel chains, and provides guidance on matching chain materials to environmental exposure, regulatory requirements (including food-handling considerations), and operational demands.

This paper is intended to support informed decision-making and encourages consultation with chain manufacturers for unique or demanding applications. It is provided free of charge as a service to the conveying industry.

An inclined screw conveyor is arranged to convey bulk material up an inclined path and is often very desirable as it may solve a conveying problem with a minimum of equipment and occupy a minimum of space.  

A vertical screw conveyor is one that conveys material upward in a vertical path. Vertical screw conveyors are sometimes called “lifts” or “elevators,” but such names are ambiguous. They require less space than some other forms of elevating conveyors.
