A static mixer is an efficient blending equipment without moving parts. In addition to its widespread application in the oil refining and chemical industries, it is also extensively used in pharmaceuticals, food, mining and metallurgy, plastic extrusion, and environmental protection sectors. Compared to traditional mixing equipment such as agitators, colloid mills, homogenizers, and Venturi tubes, it boasts advantages such as simple process, compact structure, low energy consumption, low investment, high operational flexibility, no maintenance required, and excellent blending performance. It can replace traditional equipment for processes involving liquid-liquid, liquid-gas, liquid-solid, gas-gas mixing, emulsification, neutralization, absorption, extraction, reaction, and enhanced heat transfer.
Pressure Drop Calculation for Static Mixers
Static mixers are used in pipelines, and the pressure drop they generate is relatively small. When the system pressure using a static mixer is high, the pressure drop caused by the static mixer can be ignored. If the system pressure using a static mixer is low, the pressure drop of the static mixer should be verified. The calculation method for pressure drop varies depending on the mixer model. For calculations, please contact our technical department.

Appendix: SN Type Distributor
Product Features
During the transportation of fluids, the mixture ratio is often affected due to unbalanced pressure among different fluid streams. To better accommodate the use of static mixers by our customers, our company has newly developed the SN-type distributor, which features the performance of a jet pressure booster pump. It ensures the required pressure at the outlet of the material while maintaining the substream flow rate. The SN-type distributor consists of nozzles, reception chambers, mixing chambers, and diffuser chambers. The mainstream passes through the nozzle, forming a low-pressure area at the conical inlet due to its high velocity, thereby drawing the substream into the reception chamber, accelerating it, and causing intense swirling in the mixing chamber. It is then ejected from the diffuser chamber at a certain speed, facilitating smooth transportation to the static mixer for mixing, thereby achieving optimal performance.
Product Applications
For two or more fluid feeds, use a Venturi-shaped distributor when the main and secondary stream pressures are unbalanced, and a standard distributor when the main and secondary stream pressures are balanced.
