Abstract
A towline conveyor including both straight and curved sections employs self-lubricating non-metallic wearing blocks against which a metallic chain moves. The wearing blocks are made of a polymer matrix having additives to increase resistance to wear and abrasion, providing extended life relative to metal rollers. Preferably, the wearing blocks are molded replaceable inserts for carrier blocks mounted on the track of the conveyor.
