CHUTE DESIGN CONSIDERATIONS FOR FEEDING AND TRANSFER
feeders onto conveyor belts. In other cases, transfer chutes are employed to direct the flow of bulk material from one conveyor belt to another, often via a three dimensional path. The importance of correct chute design to ensure efficient transfer of bulk solids without spillage and blockages and with minimum chute and belt wear cannot be too strongly emphasised. The importance is accentuated ...
