Overview
Glass lined agitator mixer is a key component used in glass lined reactors and vessels, designed for efficient mixing duties and reliable process performance. It is manufactured by applying high-silica glass enamel onto a carbon steel substrate, followed by firing at 800–950°C to create a durable, corrosion-resistant surface.
Combining the chemical stability of glass with the mechanical strength of steel, glass lined agitators are widely used in reactor stirring systems for chemical, pharmaceutical, and industrial applications. They are essential for achieving uniform mixing, improving heat transfer, and ensuring consistent reaction results.
The selection of agitator type, enamel grade, and drive system should be based on process conditions such as viscosity, temperature, pressure, and corrosive media.
Agitator Types
Different glass lined agitator types are designed to meet specific mixing duties and process requirements:
- Anchor Agitator
Designed for high viscosity mixing duties with strong wall-scraping capability to enhance heat transfer. - Frame Agitator
Suitable for large-volume stirring systems, providing stable and uniform circulation. - Paddle Agitator
General-purpose agitator mixer for medium viscosity blending and mixing processes. - Turbine Agitator
Ideal for dispersion, gas-liquid mixing, and improving reaction efficiency. - Propeller Agitator
High-speed mixing solution for low viscosity fluids and fast circulation systems.
How to Select the Right Glass Lined Agitator
The selection of glass lined agitator type should be based on process viscosity, mixing intensity, heat transfer requirements, and reactor operating conditions.
Different agitator designs are suitable for different reactor mixing duties and process applications.
| Process Requirement | Recommended Agitator Type |
|---|---|
| High viscosity materials | Anchor Agitator |
| Heat transfer enhancement | Frame Agitator |
| General blending applications | Paddle Agitator |
| Gas-liquid dispersion | Turbine Agitator |
| Low viscosity fast circulation | Propeller Agitator |
Anchor and frame agitators are commonly used in high viscosity reactor systems requiring efficient heat transfer and wall scraping performance. Turbine and propeller agitators are preferred for dispersion and rapid circulation processes, while paddle agitators are suitable for stable general-purpose mixing applications.
