Vibrating Subfloor Prevents Buildup in Conveyor Discharge Chutes

The Martin Vibrating Dribble Chute prevents carryback released by secondary conveyor belt cleaners from sticking to the rear slope of the discharge chute. If left to build up, material can encapsulate secondary cleaners and deposit harmful carryback onto the return side of the belt, fouling idlers, and pulleys.

The Vibrating Dribble Chute uses material disruption to cause tacky sludge and fines to fall from the chute wall and back into the main discharge flow. By addressing these issues operators can experience a reduction in maintenance hours, equipment replacement and downtime, lowering the overall cost of operation.

Martin engineers observed that the majority of the buildup released by secondary cleaners collected at the rear of the chute mouth, where a sloped surface can trap carryback. “We discovered that this could happen with nearly every discharge chute conveying adherent material,” said Dan Marshall, product engineer for Martin Engineering. “In some cases, even chutes treated with a low-friction coating can experience buildup. It’s only with the persistent disruption from vibration that we found materials flowed consistently.”
