Discharging a Sigma Blade Mixer

Designs for discharging a sigma mixer depend on the characteristics of the product and the need for process containment. There are three basic designs of discharge.

  • Tilting discharge is done by rotating and tilting the bowl about 110° and dumping the product out. This is the most common method of discharging a sigma blade mixer especially for heavy masses and solids such as ceramics, powdered metals and carbon.
  • Bottom discharge on sigma blade mixers can be large swing away doors in the bowl or free flowing liquid, flush bottom ball valves in the bowl bottom will facilitate discharge.
  • Extruder or discharge screws can be used and are mounted where saddle would normally be to discharge a double arm mixer. During mixing the flighted screw runs backwards to keep product in the mixing chamber and to discharge the screw is reversed and purchased the product our through the screw barrel. These are not actually high-pressure extrusion screws but are used primarily for discharge. A discharge screw is ideal for keeping the process enclosed when the product cannot be exposed to air or the release of noxious fumes.

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
