Horizontal Blenders consist
of a U-shaped horizontal trough and a specially fabricated ribbon or paddle
type agitator. A ribbon agitator consists of a set of inner and outer
helical agitators. The outer ribbon moves materials in one direction and
the inner ribbon moves the materials in the opposite direction. The ribbons
rotate at approx. 300 fpm moves materials both radial and laterally to
insure thorough blends in short cycle times. Ribbon agitators are used
for blends that will be between 40 and 100% of the rated capacity of the
blender. An alternate agitator is our paddle design. The paddles are positioned
to move materials in opposing lateral directions and radial. |

Vertical Blenders are an excellent
design alternative for applications that are shear sensitive or where
space on the plant floor is at a minimum. The gentle blending action of
the slow turning blending screw is far more gentle than that of a horizontal
blender. The blending screw orbits the conical vessel wall while it turns
and gently lifts material upward. The materials are then thrust at the
upper most batch level towards the center of the vessel, and then move
slowly back down the center, while mixing with materials being moved upward
by the orbiting screw.
When compared to horizontal blenders this design has several advantages:
- Gentle blending action is
ideal for friable or shear sensitive materials.
- One blender can be used
for a wide range of batch sizes, ranging from as small as 10% of the
rated capacity.
- Nearly 100% of the blended
materials are discharged through the bottom valve after completion of
the blend cycle.
- Use nearly 50% less power
per unit being blended.
