Types of Roller Chain Conveyors

Nine types of chain conveyors were described in the chapter on engineering steel chain conveyors. The descriptions are very detailed and are not repeated here. Designers should refer to chapter 9 for more iirformafion. Roller chains can be used on any of the listed conveyor types. However, good practice dictates against using roller chain in a few of those conveyor types. 

The most common uses for roller chains probably are in carrier and slat conveyors. RoUct chains are seldom used in apron or scraper conveyors that carry bulk materials. This is because the small clearances in roller chain easily become packed and clogged with the loose conveyed matmal. If roller chain is used in one of these conveyor types, the chain should be well shielded from the loose material. 

Roller chains are almost never used in drag conveyors. The chain runs in the conveyed material in a drag conveyor and the chain cannot be shielded from the loose material. 

This chapter does not cover roller chains conveying bulk materials in drag or scraper conveyor applications. The designer should consult an ACA roller chain manufacturer for help with these applications.
