PATTERSON Industries Canada "The Process Equipment People" designs, engineers and manufactures a full range of ThoroBlender® Double Cone Blenders to suit various blending and production requirements.

At the Research & Development level, PATTERSON offers the Porta-Shell Blending System that incorporates a ThoroBlender® Double Cone Blender Body feature. More information on this unit and the sizes offered can be accessed under Porta-Shell Blending Systems.

The PATTERSON Type 'A' ThoroBlender® is also used for Research & Development, Pilot Plant, Pre-Production and small scale production.

ThoroBlender® Type 'A'

This compact design is recommended for laboratory and pilot plant operations, as well as for small production requirements. It features a large opening to facilitate removal of contents. This simplifies cleaning when changing from one product or color to another. It is available in operating capacities from 1 to 8.7 cubic feet.

ThoroBlender® Type 'B'

The ThoroBlender® Type 'B' is the most widely used processing system for rapidly blending production quantities of dry powders, colors, pigments, metals, metal powders, synthetic products, fine and heavy chemicals, photographic chemicals, dyes and intermediates, resins, molding powders, plastics, pharmaceuticals, medicinals, fertilizers, prepared flour and cake mixes, baking powders, tobacco, feeds, grains and other food products, insecticides, detergent powders, non metallic minerals and all kinds of free flowing dry materials. It produces a homogeneous, uniform product in a minimum of time even when additions as small as 1% or 2% are made to the batch. Operating capacities range from 1 to 5200 cubic feet.

ThoroBlender® Type 'C'

The unique Double Cone dry material Blender requires minimum floor space and its cantilevered design allows you to position it in any number of places to match your work flow.

Its three-sided accessibility means valuable savings in time when loading or unloading. Mounted directly on a sturdy pedestal, it can be operated and serviced from three sides.

The high clearance under the discharge nozzle speeds operations and permits easy access to keep the work area clean.

The Type 'C' ThoroBlender® is economically priced, easy to install and will result in cost effective performance throughout its life.

Because it costs less to build and install, the Type 'C' will save on initial cost, on installation, and on continuing operation throughout its life.

The Type 'C' Blender is offered in size ranges from 1 cubic foot working capacity all the way up to 20 cubic feet.

Design Features:

  • Three-side accessibility
  • Higher clearance under discharge
  • Small floor space requirements
  • Competitively priced
  • Dependable blending

The PATTERSON Double Cone ThoroBlender® achieves absolute homogeneity in the blending of a wide variety of free-flowing, dry materials. This is accomplished even with dry materials, which are dissimilar in particle size and shape, because the double cone design interfolds the material regardless of its flow properties.

The PATTERSON ThoroBlender® combines a precisely engineered double cone design, and a rotating speed calculated to produce a fast homogeneous blend.


As the ThoroBlender® rotates, the material at the sides nearest the axis starts to cascade first, striking the sloping sides of the cone where it is deflected toward the centre. The progressive cascading action moves material from the smallest axial radius and toward the centre. The speed of the unit determines the point of rotation at which the material starts to cascade.

A second action takes place simultaneously with the cascading action. Material falling into the middle of the blender spreads apart as it falls, mixing with the material flowing inwardly from the sides. The double blending action is so rapid and effective that particles of different physical properties cannot separate, and are interspersed uniformly throughout the batch.

The blending action continues as long as the blender rotates. Discharge is rapid and complete. There are no corners or vanes to hold or carry material from batch to batch. Both charging and discharging action are by gravity flow and arranged so that the blender may be installed in a continuous process operation.

The ThoroBlender® mixing efficiency is exceptionally high and substantially reduces mixing time. Charging is fast and clean, and discharge is quick, thorough and direct. The operation is completely dust-free. Mixing is gentle and uniform; power requirements are low; and blending cycles are short.

PATTERSON ThoroBlenders® are available in carbon steel, stainless steel and special alloys. Where it is necessary to blend extremely finely divided materials which tend to form tightly bonded agglomerates, the ThoroBlender® is supplied with a special internal disintegrating or dispersing element to assure rapid mixing and blending in a single operation.

Laboratory models from 18" (.46 m) diameter to 3'0" (.92 m) and production models from 3'6" (1.07 m) to 16'0" diameter (4.9 m) are standard. Larger sizes up to 5,000 cu. ft. (140 cu. m) working capacity have been built for special applications.

The ThoroBlender® may be jacketed for heating or cooling and can be equipped for flash drying, spray coating or particle disintegrating. Liquids may be introduced and uniformly blended with dry materials.

The PATTERSON ThoroBlender® is used for blending and mixing:

  • Dry Powders and Color Pigments
  • Minerals
  • Synthetic Products
  • Fine and Heavy Chemicals
  • Photographic Chemicals
  • Dyes and Intermediates
  • Resins and Plastics
  • Molding Powders
