V - Blender V - Blender, such as the V-blender, are simple in concept and commonly used in industrial processes. They are employed to mix pharmaceuticals, chemicals, food, fertilizers, plastics and many other particulate materials. V-blenders consist of two cylindrical sections joined at an angle of around 90°. The mixer is rotated about a horizontal axis, with mixing resulting from the tumbling motion of the particles. Internal baffles are sometimes used to improve mixing performance. V-blenders are designed for batch operation.
