5. How Does RST Determine the Right Industrial Mixer Design?

Selecting the right industrial mixer involves more than simply considering tank capacity or motor power.

The engineering team needs to understand the product characteristics and specific production requirements.

The main parameters include:

1. Viscosity: The resistance of a material to flow.

2. Specific Gravity (SG): The ratio of material density to the density of water.

3. Batch Size: The amount of material processed in one batch.

4. Material Characteristics: Whether the material is powder, liquid, slurry, or thixotropic.

5. Mixing Objective: Whether the process requires blending, dispersion, homogenization, or dissolving.

6. Operating Temperature: The temperature during the production process.

7. Required Process Time: The time needed to achieve the desired mixing results.

Based on these parameters, the engineering team can evaluate:

• Agitator and impeller types.

• Mixing blade or disc diameter.

• Rotational speed (RPM).

• Motor power requirements (kW/HP).

• Gearbox and transmission systems.

• Drive systems and variable frequency drives (VFD).

• Machine construction materials.

This engineering approach helps ensure that the equipment is designed according to actual process requirements rather than tank dimensions alone.
