 Blenders >> Verticle Screw Blender

Vertical Screw BlenderVertical 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 capacity.
  • 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.

Features

  • 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.

Application

  • Dry mixing of free flowing powders, granules requiring low shearing force.
  • Excellent for bulk drugs, chemicals.
