Ribbon Blender is most ideal for mixing dry powder, granules and slurry. This consists of an open trough with an approximately semi cylindrical bottom. With in this trough two or more “Ribbon spirals”. One spiral is right -handed and the other left-handed. When these ribbons are rotated, the material is worked back and forth in the trough. These machines may be jacketed for heating or cooling, and may be closed to retain volatile solvents. This equipment finds application in Food, Paint and Polymer industries
