Glass-Lined Propeller Agitator

Glass-Lined Equipment Customization

ASTM-Standard Steel Materials Carbon steel, alloy steel, stainless steel
Enhanced Enamel Formulations Superior resistance to corrosion, high temperature, acids and alkalis
Precision-Controlled Manufacturing Cold spray with curve firing for uniform enamel thickness and density

The propeller agitator is suitable for glass-lined reactors with capacities from 50L to 32000l. It is a strong choice for processes that require fast liquid circulation, efficient blending, and gentle handling of low-viscosity media. The propeller agitator is especially suitable for applications such as crystallization and extraction, where efficient mixing with relatively low shear is important.

With two or three blades and a gradually curved blade profile, the Propeller Agitator creates a strong pumping effect during high-speed operation. This flow pattern moves material up and down along the reactor wall and generates pronounced axial circulation for fast and effective mixing.

Features

Strong axial circulation for fast mixing
The propeller agitator creates a strong axial flow that helps move material quickly through the reactor and improves overall mixing efficiency.
Suitable for low-viscosity and low-solid systems
The propeller agitator is designed for low-viscosity liquids and systems with low solid content, making it a practical option for processes that require rapid but controlled mixing.
Low and uniform shear distribution
The propeller agitator provides relatively low and evenly distributed shear, which helps support a more consistent particle size distribution in suitable crystallization processes.
Efficient mixing under the same power input
Under the same energy consumption conditions, the Propeller Agitator can generate a larger material turnover volume, which helps shorten reaction time in appropriate applications.
Flexible design based on process requirements
The agitator diameter is typically 0.3 to 0.5 times the inner diameter of the reactor, and the operating speed can be adjusted according to material properties and process needs.
Structure designed for reliable glass lining performance
The agitator shaft uses export-grade seamless steel pipe, while the blades are made from titanium-alloy steel plate, which supports stable glass lining quality. The pipe ends use a closed-end head structure to reduce stress concentration and lower the risk of enamel chipping.

Why Us

Certified manufacturing standards
We hold authoritative ASME (Section VIII Division 1) and CE (PED) certifications, ensuring full compliance with international safety and quality standards. This guarantees our glass-lined steel equipment meets the strict regulatory requirements of global chemical, pharmaceutical, and agrochemical clients.
In-House Enamel R&D Laboratory
Our dedicated in-house R&D center specializes in custom enamel formulations, including acid-resistant, acid-alkali resistant, high-temperature resistant, and wear resistant options. These proprietary formulas deliver exceptional durability against corrosive media, mechanical impact, and thermal shock, ensuring reliable performance in diverse operating environments.
Advanced Cold Spray Enameling Process
Our glass-lined equipment utilizes advanced cold spray enameling process with multiple high-temperature firing cycles. This technology ensures a thinner, more uniform, and denser enamel layer with significantly reduced risk of chipping or peeling. The controlled firing process guarantees optimal adhesion and long-term durability in the most demanding chemical processing conditions.

Precision Belt Polishing Pretreatment
Prior to enameling, every steel shell undergoes rigorous precision belt polishing to thoroughly remove mill scale, pits, and surface impurities. This meticulous pretreatment process ensures superior substrate smoothness and integrity, providing an ideal, contamination-free foundation for strong and uniform enamel bonding.
Multi-zone electric furnace control
The enameling furnace uses independent multi-zone control with computerized management of heating, holding, and cooling. The temperature difference inside the furnace is controlled within 5°C, helping maintain consistent firing quality.
Vertical firing process
All equipment is produced using a vertical firing process, which provides more even heating, reduces deformation, and helps maintain the overall appearance of the equipment as well as flange flatness.
Controlled slow firing curve
The firing process follows a low-temperature entry and low-temperature exit slow-firing curve. Combined with dedicated furnace tooling and controlled firing methods, this helps ensure enamel quality comparable to that of established international manufacturers.
Full-process quality management
We maintain a complete quality management system with full-process control. For glass-lined quality inspection, we apply three inspection procedures covering:
1. internal and external visible defects
2. enamel thickness
3. high-voltage spark testing
This helps ensure that delivered products meet required standards and specifications.
Custom non-standard equipment design and manufacturing
Custom design and manufacturing support is available for non-standard products. Based on different process requirements, tailored solutions can be developed for special equipment structures and agitator selection supported by CFD fluid dynamics simulation.
Strong R&D capability
We have strong research and development capacity and currently hold more than 40 national patents covering equipment tooling, products, and manufacturing processes.
