Ribbon Blender Design Features & Options

Ribbon blenders are commonly used but they are not so universal that we can ignore their limitations. Ribbon blenders are very effective but only within a range of parameters. The below ribbon mixer characteristics should be considered based on the way a ribbon blender operates.

  • Sanitary design improves discharge and makes cleaning easier and more thorough.
  • Slide-gate discharge valve with pneumatic actuator (lab models IMB-1 and 2.5 are manual).
  • 304 stainless steel contact surfaces, packing gland, support structure and chain guard.
  • All internal and external welds are radiused, ground smooth, flush and pit free. 200 grit polish inside and out.
  • Shaft packing gland housing is split for easy maintenance.
  • Provision for gas or liquid purge.
  • Sealed pillow block roller bearings.
  • Heavy-duty Class-III gear reducer and chain drive.
  • Fully welded 304 stainless steel agitator and shaft with flanged ends for easy removal.
  • 1-, 2- or 3-piece hinged covers with removable grates. Limit switches* provided for each cover or grate section.


Any blender can be raised from a few inches to 16 feet. All welded square tubular 304 stainless steel (epoxy coated carbon steel also available) with cross members and machined mounting pads for blender feet. Legs can also be drilled to accommodate electronic load cells. Front of stand is open for entry of bins, bulk bags and other containers. Available for all new or previously installed blenders.

Ribbon Blender working capacities from 1 to 515 cubic foot are standard. Ribbon mixers can be manufacturered up to 1,500 cubic foot capacity.

Ribbon Blender Design Options:

  • Extended legs
  • Modified covers with various loading ports.
  • Liquid addition spray bar and nozzles
  • 304L or 316L stainless steel
  • Paddle agitators or ribbon-paddle agitators
  • Auger discharge
  • End or multiple discharge points
  • Ball valve or flush bottom plug valves
  • High-intensity side-entering choppers
  • Heating or cooling jackets including ASME code
  • Product thermowell
  • Internal vacuum design
  • Explosion Proof Motors
  • Higher HP drives
  • Shaft-mounted or hollow-bore gear reducers
  • Controls in NEMA-12, 4, 4X or 7&9 or purged
  • Soft-start or variable frequency drives

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

Laboratory Mixers

Aaron Process LNG Laboratory Mixers are available in working capacities from 1/4 gallon to 2 gallon. 1/4 gallon and 1 gallon models are available from stock and furnished with variable speed drives, stainless steel construction and jackets as standard. These units are ideal for research and development, testing new raw materials or scaling up production size batches
