For low viscosity liquids, traditional propulsion, propeller, and turbine impellers can already solve the problem. Anchor and frame impellers cover a wide range of viscosity. In the low viscosity range, its shear stress is insufficient, axial circulation is poor, and due to the large ratio of blade diameter to groove diameter, the volume of the solid rotor is also large. Therefore, it is only used in situations where the requirements for stirring effect are not high. However, for situations where heat transfer is the purpose of agitation, anchor impellers are still suitable.
During the mixing process of the screw belt mixer, the material inside is subjected to two opposite directions of rotor motion, resulting in a composite motion. The dual axis blade carries the animal material to rotate clockwise and counterclockwise along the inner wall of the machine slot, and the material near the axis rotates axially. It adopts a U-shaped barrel structure, which runs smoothly, mixes evenly, has no dead corners, and discharges cleanly. It has a wide range of applications.
