Features Vibrating grizzly feeder/scalper

Roc Impact (ROC) vibrating grizzly feeders are designed mainly for fixed primary crushing plants. They regulate the feed rate to the crusher while separating materials by size.

The vibration unit is run by two vibrators located underneath, or with a motor-driven eccentric driveshaft.

They create a linear vibrating motion with an incline of 45° to the horizontal frame of the feeder (depending on the installation).
  • A wear-resistant electrode extends the life of the feeder.
  • The design of the rods allows them to spread make it easier to remove blockages and to maximize size-based sorting.
  • Four sets of springs or rubber mounts support the feeder to better stabilize it during operation.
  • Feed rate can be controlled remotely thanks to the variable speed motor.
