A ribbon blade mixer is a type of industrial mixing equipment used to blend a variety of materials. It consists of a cylindrical vessel with a set of internal horizontal blades that rotate around a vertical axis. The blades are arranged in a helical pattern and extend from the center of the vessel to the walls of the vessel. The rotation of the blades creates a mixing action that moves material from one end of the vessel to the other. Ribbon blenders are widely used in the food, pharmaceutical, and chemical industries.
