A NetterVibration customer in the chemical manufacturing industry was using a feeder system to fill boxes with a bulk solid powder for shipping. The feeder was configured to fill six boxes simultaneously. During the filling process, a cone-shaped mound formed on top of the material, extending above the top of the box.
The customer installed an NTK 8 AL pneumatic linear vibrator to the table, vibrating the boxes while and after they are filled, flattening the angle of repose and allowing for more product to be put in the box before closing and sealing it. As a result, the customer was able to ship more product on each truckload, substantially reducing shipping costs.
