| 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 Gemco 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
Gemco 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 Gemco D/3 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. Invented by Gemco in 1935,
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%.
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
Gemco offers three different distinct vessel shapes, the Slant Cone, Double Cone and V-shape. Three
shapes provide the ability to select a system best suited to your particular applications. All three
designs can be fitted with an internal agitator. |
