Spiral type mixing blade

Suitable for mixing, heat transfer, reaction, and dissolution processes of high viscosity or powder materials

1. Confirmstirring paddleMixing purpose: Whether it is necessary to achieve process objectives such as heat transfer, absorption, extraction, dissolution, crystallization, etc. for liquid-liquid mixing, solid-liquid suspension, gas-liquid or liquid-liquid dispersion. Select the mixing blade form according to the process characteristics.

2. Calculate the power required for mixing operation: the power required during the mixing process

Reference formula: Power=Power Precision * Liquid Density * 3rd Power of Rotation * 5th Power of Slurry Diameter.

The calculation of power accuracy is complex and related to tank diameter, slurry diameter, blade width, angle, number of layers, viscosity, number of baffles, and baffle size.

3. Choose motor power: Considering efficiency, the calculated value should be greater than or equal to 1.5 times the mixing operation power.

4. Regarding the determination of the minimum critical stirring speed: This speed is the minimum speed that meets the stirring purpose, not the critical speed of the stirring shaft.

5. Select and verify the stiffness and strength of the mixing shaft and propeller based on power.

6. When using a reduction gear, it is also necessary to consider the coefficient of use of the reduction gear and the bearing capacity of the reduction gear
