A bar screen (10) conveyor system (20) for collecting debris or the like in a stream of liquid (8), including collector rakes (40) for attachment to the conveyor which are made of a tough, abrasion-resistant and corrosion-resistant elastomer. The preferred elastomers for use in rake fabrication are polyurethane elastomers. The conveyor systems which include the elastomeric rakes have greater durability and use life without problems than the heretofore conveyor systems utilizing metal rakes. |
