We are looking for a telescopic chutes manufacturer based in the U.S.A. The application is to fill a stockyard with humid coal ash, using a radial belt conveyor working at a flow rate of 540 metric tons per hour (600 stph). The material is quite abrasive, fine and not sharp.The chute should have a proximity sensor in order to work automatically.

Don't know if it would be better to use steel or canvas to make this kind of chute. ■
