Blending in its simplest form is the combining of two or more materials to produce a homogeneous mixture. These materials may be any combination of particulate (solids blending) or particulate and liquid (liquid-solid blending). Normal tumble blending of free-flowing materials provides a gentle mixing action. For materials that tend to lump or for high intensity blending, an internal agitator is utilized. Critical to any blending operation is the quality of the blend, i.e., batch variations. Different applications have varying requirements for product uniformity.
Slant Cone
The asymmetrical geometry of the Slant Cone design offers a very fast blend time. High particle mobility, plus the intermeshing action of materials results in blend times up to 33 percent less than other designs. In addition, this concept achieves more control and more precise end product with blend variation as low as ½ percent.
V-Shape
V-shape blenders are very popular in a wide variety of industries. They offer both short blending times…and efficient blending. The blend is achieved by the constant, dividing and intermeshing particle movement provided by two connected cylinders. This precise mixing action results in blend variations of 1-2%. Each cylindrical leg has an access cover for easy material loading and cleaning. The V, as all tumble blenders, requires low maintenance and consumes little horsepower.
Double Cone
The unique design of the Double Cone Blender results in a high degree of particle mobility without the use of internal baffles. This type of blender has a low profile, requiring less head-room than a V-blender. One access cover means easier cleaning and inspection, the Double Cone is a proven performer in a wide variety of industries, offering greater overall volume and high efficiency with blend variations 1-2%.
Octagonal Blender
The unit is used for blending the most delicate & fragile free flow products like powder or granules in 10 to 20 minutes. It is also the best way to mix very heavy & abrasive products the range of products includes colour, plastic, flour, drugs, pharmaceuticals, metal powders, minerals, fibers & many other.
Working Principle:
It is revolved over and over, moving the products in & out of the constricted octagonal areas. This causes multiple folding action that ensure a thorough blending of all the ingredients in the batch. The result is a homogeneous blend regardless of particle size distribution, particle shape or density with a great efficiency.

Considerations in Blender Selection
Before selecting any blending system, it is necessary to understand the characteristics of the materials to be blended, how the material is transported to and from the blender, and how the blender will be integrated into the plant. Key considerations include:
- Material characteristics
- Loading and unloading requirements
- Easy product changeover
- Man-power availability
- Material lumping
- Single-floor or multi-floor operation
- Daily through-put requirements
- Process flow* Specific industry regulations
- Dust control
- Safety
