Ribbon Blending (D)

Ribbon blending is a long established blending technology that creates many material handling challenges both in the loading and unloading process. Rheo offers a few customizable material handling packages for this process. The Vacuum Transfer Station package offers a portable vacuum transfer system that comes with an operator workstation and a portable lifter to lift and position the vacuum canister above the blender opening. A Ventilation Sleeve can be place on the top opening of blender for local dust extraction. The Mobile Ventilation Sleeve or portable Product Screener can be used to capture airborne dust during the emptying process of the blender. The vacuum system can also be used wand out any remaining residual powder that may not get fully removed during the emptying process.
