Rotary Impeller Stirrer

The rotary stirrer drives the stirring paddle to rotate through a motor, ensuring uniform mixing of liquids or mixtures. It is used for laboratory sample preparation, chemical reactions, and dissolution processes. In the coatings and inks industry, it is employed for pigment dispersion, and in the plastics industry, it is used for resin mixing.
Selection
Select a motor with the corresponding torque based on the viscosity of the material. Consider matching the container size to the diameter of the stirring paddle. A speed adjustment function is required to adapt to different mixing stages. Pay attention to the corrosion resistance of the material; stainless steel is suitable for most chemical environments. The fixing method must ensure operational stability.
