A Ribbon Blender is a highly versatile type of MIXER/BLENDER primarily used for the fast, homogeneous mixing of dry powders, granules, and occasionally liquids into solids. It features a horizontal, U-shaped trough and a central rotating element fitted with a set of inner and outer helical ribbons. The outer ribbon moves the material toward the ends of the trough, while the inner ribbon moves the material back toward the center. This opposing motion creates intense shear and radial flow, ensuring efficient, high-capacity blending over short cycle times.
