There are significant differences between the ribbon mixer and the paddle mixer in terms of structure, working principle, mixing effect, power consumption, scope of use and maintenance difficulty.
1. Structural differences
The ribbon mixer consists of a ribbon and a shell. The ribbon rotates in the shell to mix the mixing materials.
The ribbon is usually divided into an inner spiral blade and an outer spiral blade, which are used to push the material downward and pull the material upward respectively.
The internal structure of the ribbon mixer is simple, generally composed of a motor, a reducer, a barrel, etc.
The paddle mixer consists of a motor, a rotor and several paddles.
The paddles are usually installed on the shaft, and the shaft is driven by the motor through a reducer or directly.
The structure is relatively complex and requires more maintenance and care.
2. Working principle
The ribbon mixer rotates the ribbon, the inner spiral blade pushes the material downward, and the outer spiral blade pulls the material upward, so that the material is continuously turned and mixed in the barrel.
The centrifugal force generated by the high-speed rotation of the spiral blade also accelerates and turns the material, improving the mixing efficiency.
The paddle mixer drives the paddle to rotate through the motor, generating strong shear force and flow force, so that the materials in the mixing tank are mixed and stirred violently.
The shape and angle of the paddle have a great influence on the stirring effect. Different paddle designs can adapt to different material characteristics and stirring requirements.
3. Stirring effect and scope of application
The spiral ribbon mixer has a relatively uniform stirring effect and is suitable for mixing dry powder, particles, solids and liquids.
It is especially suitable for mixing and stirring materials such as powders, particles, mixtures, and is widely used in chemical, pharmaceutical, food and other fields. However, for materials with higher viscosity, the stirring effect may not be good.
The paddle mixer has a strong stirring effect and is suitable for mixing materials with higher viscosity, such as paint, resin, etc.
It can also be used for stirring high-viscosity fluids to promote the upper and lower exchanges of fluids.
4. Power consumption and efficiency
The spiral ribbon mixer has low power consumption, but the mixing efficiency is also relatively low.
The paddle mixer has relatively high power consumption, but the mixing efficiency is also high, and the materials can be quickly mixed evenly.
