Ribbon Mixer

Name:
Ribbon Mixer
Detailed information:
A mixing or blending machine whose essential components are a steel bowl or trough, jacketed for temperature control, within which rotates an agitating device consisting of two or more metal strips (ribbons) pitched in opposite directions spirally arranged around a central shaft. The curved and reverse-pitched ribbons operate on the principle of the screw; the material is moved forward by one ribbon and backward by another, so that efficient mixing is effected. Continuous operation is possible in some types. Such equipment is used for mixing dry powders, viscous liquids, slurries, etc., as well as for drying, crystallizing, and deaerating. Large sizes have a bowl diameter of 5 ft and a length of 9.5 feet.
