Bear Iron Works Koala Vibco Vibrator Installation for Grizzly Rock Screen

The Bear Iron Works Koala Vibrator Installation is an optional factory-installed vibration system designed to improve material flow and screening performance on the Koala Grizzly Rock Screen.

Adding vibration helps move material across the Grizzly more consistently, making it especially useful when processing wet, sticky, fine, or moisture-rich soil that may not flow as easily across a gravity-only screen.

Bear Iron Works' imported product catalog identifies this Koala-specific installation as using a Vibco vibrator and provides a dedicated installation SKU, indicating that this is a configured accessory for the Koala rather than a generic loose vibrator.

The vibrator complements the Koala's standard solid-steel Grizzly rails and can also be useful when working with optional removable screens, where finer material needs additional movement to pass efficiently through the screening media.

Bear specifically recommends the vibrator option when screening wet, sticky, clay-rich, or fine material.

When should you add the vibrator?

Dry, loose material: The standard Koala can generally operate using gravity and normal equipment loading without a vibrator.

Wet or sticky soil: Adding the vibrator can help material move across the screen instead of accumulating on the screening surface.

Clay-rich material: Vibration can help break up material flow and reduce buildup during screening.

Fine screening: The vibrator can be particularly useful when using a removable screen with smaller openings, where material requires more movement to pass through the screen efficiently.
