Design: The ribbon blender consists of a horizontal trough with a central shaft equipped with helical ribbons or blades. The ribbons rotate in opposite directions, creating a continuous and efficient mixing action.
Mixing Action: As the ribbons turn, they push the material towards the center of the blender, and then back out towards the ends. This movement creates a thorough and consistent blend of powders by repeatedly folding and tumbling the materials.
Discharge: Once mixing is complete, the powder can be discharged from the blender through a valve or an opening at the bottom. Some ribbon blenders have a hinged discharge gate for easier cleaning and material removal.
