Screw Blenders are excellent design alternatives
for product applications that are shear sensitive,
voluminous and also where space on the plant
floor is at a minimum.
The blending action of the slow
turning screw is far gentler than that taking
place within the horizontal blenders. Since
the active blending volume at any given time
is a lot lesser than the horizontal blenders,
it results in a lower power requirement. The
principle of blending is based on the differential
travel speeds of product particles in the conical
section of the vessel. The material from the
bottom section of vessel is lifted by the screw
and spread over the upper sections. The large
handling capacity coupled with low power requirement
makes it one of most effective and efficient
Blender within the family.
When compared to horizontal
blenders this design has several advantages:
- Gentle blending action is
ideal for friable or shear sensitive materials.
- Blender can be used to produce
uniform blend for a wide range of batch sizes,
ranging from as small as 10% of the rated
- Near 100% of the blended
materials are discharged through the bottom
valve after completion of the blend cycle.
- When compared to the horizontal
blenders, it uses nearly 75% less power per
unit being blended.
- Occupies less floor-space
and are ideally suited to multi-storey facilities.
- Available in all grades
of Carbon Steel and Stainless Steel.
- Double Screw Blenders
offered for very large batch sizes.
- Available in
sizes from 5000 liters to 50000 liters,
other sizes manufactured on request.
- Dry mixing of free
flowing powders, granules requiring
low shearing force.
- Excellent for bulk
