Ribbon Blenders consist of a U-shaped horizontal trough and a specially designed and fabricated Double Helical Ribbon Shaft rotating within. A ribbon agitator consists of a set of inner and outer helical ribbons. The outer ribbons move the
material from the ends to the center while the inner ribbons move the material from the center to ends. This counter-current action causes good blending. The ribbons rotate at approximately 100 meters per minute and move the 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 the 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 25% of the total capacity are going to be mixed in one blender.
Applications
•Ribbon design is suitable for dry mixing of free flowing powders requiring low shear force.
•Paddle design for dry/wet mixing of dense products.
•Ribbon design is appropriate for low and medium duty applications, while Paddle design is suitable for heavy duty applications.
•Blending large volumes of dry solids.
•Dry powder to wet phase mixing.
•Mixing of bulk drugs, chemicals, and cosmetic powders.
•Dry Blending of capsule formulations.
•Lubrication of dry granules in large quantity.
