Martin Engineering Offers Vibrating Dribble Chute


ptp DribbleChute 400A global leader in bulk material handling offers an innovative solution that 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 Martin 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.

Prompted by customer requests, 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. According to Dan Marshall, product engineer for Martin Engineering, “We discovered that this could happen with nearly every discharge chute conveying adherent material. 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.”

Comprised of three parts, a low-friction polyurethane dribble sheet, a steel mounting bracket and a powerful vibrator, the combination of mechanical disruption and the slick surface prevents material from adhering and feeds it back into the main discharge flow. When the unit is mounted into the existing chute-work, it often extends the rear configuration closer to the belt, increasing the amount of material captured and further reducing spillage.
