Ribbon Blenders Blending Action
Ribbon Blender comprises of a U-shaped horizontal trough and a specially designed Double Helical Ribbon Agitator rotating within. The Ribbon Agitator consists of a set of inner and outer helical ribbons. Generally, the outer ribbon flights displace the material from the ends to the center while the inner flights move the material from the center to the ends. This counter-current action results in homogenous blending. The ribbons rotate at approximately 70 - 100 meters per minute and move the material both radially and laterally to ensure thorough blends in short cycle times. Ribbon Blenders are used for blends that are between 50% and 100% of the rated capacity. An alternate design is the paddle agitator. The paddles are positioned to move the material in opposing lateral directions as well as radially. The paddle design is generally employed where friable materials are being blended, and when batches as small as 15% of the total capacity are going to be mixed in the blender.
