A horizontal ribbon mixer is a type of industrial mixer used to blend dry materials such as powders, granules, and flakes. It is an efficient mixer that utilizes a pair of counter-rotating ribbons to thoroughly mix materials in a short amount of time. The ribbons move the material in a helical pattern within the chamber, allowing for thorough and uniform blending. The exterior of the mixer is usually jacketed for temperature control, allowing for materials to be heated or cooled during the mixing process. Due to its versatility, the horizontal ribbon mixer is a popular choice for many industries including food production, pharmaceuticals, and chemicals.
