Chain conveyors are conveyor systems in which the bulk material is transported in a closed trough with the help of a chain and carriers on it. Depending on the construction, the conveyor can be horizontal, ascending or vertical.

Knoblinger specializes in scraper chain conveyors – also called scraper conveyors for short. Scratch chain conveyors are open at the top and are particularly suitable for bulky goods. The chip conveyors form a subgroup of the scraper conveyors.
