About the Ribbon Blender

The Shakti ribbon blender is a horizontal U-shaped trough fitted with a double helical ribbon agitator. The outer ribbon moves material towards one end while the inner ribbon returns it, producing a fast, homogeneous blend with low energy input.

It is used for solid–solid and solid–liquid mixing, and can be fitted with a spray system for liquid addition or a jacket for heating and cooling. Standard models run from 200 L to 10,000 L working capacity, and smaller laboratory sizes and larger custom units are available.

Working principle

Two opposed helical ribbons on a common shaft move the product in counter-current directions inside the trough: the outer ribbon conveys material towards the discharge end and the inner ribbon returns it. This axial and radial movement gives a homogeneous mix in a short cycle. Bearings are mounted on lanterns outside the mixing container to avoid contamination.
