Case Study: Eliminating Build-Up At A Crushed Stone Quarry

Problem

A crushed-stone quarry in Tennessee was experiencing problems with material build-up in the feeder hopper under their sizing screens.

Situation

The material (size 1/4″ down to fines) would cling to the hopper walls and build up, eventually stopping material flow and shutting down the screening operation.

Solution

A MARTIN® NCT™ Turbine Vibrator (NCT-108) was mounted on a channel on the end wall of the hopper. The vibrator was mounted on a 5″ x 48″ long channel and located 18″ from the bottom of the bin. After two weeks of operation, the customer reports no bin or feeder stoppages at this point. They are very pleased and we are now trying to help them solve other problems at their plant.
