Ribbon Mixer Blending Cohesion

Images

Diffusion mixing can also be affected by product cohesion. Cohesion can be the result of electrostatic forces as might be found with sulphur compounds, van der Waals forces which become more prominent as particles become smaller (typically <2 microns) and available surface area increases and moisture which can cause stable agglomerates to form. To overcome these various attractive forces and effectively disperse one solid in another, either a longer mixing time will be require or higher energy input which is often achieve by the addition of high speed agitators or choppers mounted in the side of the ribbon mixer.

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.

Ribbon Blenders

Paul O. Abbe designs and manufactures ribbon blenders which are ideal for blending dry, free-flowing solids with bulk densities up to 70 pounds per cubic foot (1.1 g/cc) depending on material characteristics including, particle size, size distribution and particle shape (morphology), angle of repose, cohesiveness and moisture level. Ribbon blender are used for all dry foods products, nutraceuticals, protein powder mixes, dry juice mixes, chemicals, fertilizer, insecticides, colorants, resins and polymers. The moderate shear of the ribbon or paddle naturally breaks down lumps and agglomerates. Ribbon blenders are extremely efficient and economical.

Rota-Cone Blenders

Tumble Blenders include the original ABBE Rota-Cone® Double Cone Blender and the Rota-V Blenders. Tumble blending offers the lowest shear method of mixing friable or delicate solids. The simple double-cone or V-designs provide complete discharge. Because there is no agitator there are no seals and they are easily inspected and cleaned. For these reasons, Tumble Blenders are often employed by the food and pharmaceuticals industrie

CrossMix® Fluidizing Mixer

The CrossMix® is a twin-paddle mixer that gently lifts and fluidizes solids in a weightless zone where particles of any size or shape can move freely and mix rapidly. Mixing can be completed in as little as 7 to 20 seconds. The CrossMix® is most beneficial for solids that require very high homogeneity, are fragile such a
