Vibrating Dribble Chute
Vibrating Dribble Chute

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.

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.

To install the dribble chute, a slot is first created in the rear sloped wall to accommodate the steel hook bracket that secures the entire unit to the chute. Lined with thick soft rubber on the inside arch to protect the chute from structural abrasion caused by constant vibration, the J-shaped bracket holds the dribble sheet secure with four bolts.

Bolted to the other side of the bracket, outside of the chute, is a unit from the extensive family of Martin Electric Vibrators, chosen by operators based on the needs of the application. Rated for continuous duty even when set at a maximum force output level, the units are housed in a totally enclosed, non-ventilated case to keep internal components protected from abrasive dust.
