Ribbon Blender Mixing Mechanisms

Ribbon Blender Mixing Mechanisms

To be cost effective ribbon blenders are loaded to the top of the agitator. Lesser ribbon blender loading will allow proportionately faster mixing. The minimum loading is about 40% of the maximum which is required to keep both the inner and outer ribbon in the product zone. The agitator RPM is designed to provide approximately 300 feet per minute tip speed. The inner and outer ribbons together rotate the mass of material. The outer ribbon moves the solids toward the center of the tough and the inner ribbon moves solids toward the ends.

Mixing time for a fully loaded mixer is typically 15 minutes and is proportional faster for lower loading. A mixer loaded only to the shaft or about 50% may blend in 7 minutes, but of course productivity will suffer ad the batch size has been halved.

The product characteristics that must be considered in selecting a ribbon blender mixing include tapped and untapped bulk densities, particle size and cohesiveness.

For special mixing applications such as powdered metals or friable materials, consider our Rota-Cone® Blenders or CrossMix® Fluidizing Mixers.

For viscous or heavy paste mixing we offer Double-Arm Mixers & Extruders.
