Ribbon Blenders consist of a U-shaped horizontal trough and a specially fabricated ribbon agitator. A ribbon agitator consists of a set of inner and outer helical agitators. The outer ribbon moves materials in one direction and the inner ribbon moves the materials in the opposite direction. The ribbons rotate at approx. 300 fpm moves materials both radially and laterally to insure thorough blends in short cycle times. Ribbon agitators are used for blends that will be between 40 and 100% of the rated capacity of the blender.
An alternate agitator is our paddle design. The paddles are positioned to move materials in opposing lateral directions and radially. The paddle design is normally applied where friable materials are being blended and when batches as small as 15% of the total capacity are going to be mixed in one blender.
