Rotary Feeder
The Rotary Feeder is one of Jiangteng's flagship products. As a professional manufacturer based in China, we provide reliable, hassle-free, and economically sustainable material conveying solutions. We offer comprehensive customization options and provide factory-direct pricing.
Designed and manufactured by Jiangteng, a Chinese specialist, the rotary feeder is a stable, highly efficient, and tightly sealed device. Serving as a critical component within pneumatic conveying systems, it guarantees the stable operation of your production line while delivering high energy efficiency and an extended service life.
Product Features
If your current needs include stable and uninterrupted material feeding, effective prevention of dust and gas leakage, durable equipment requiring minimal maintenance, and a solution that truly adapts with flexibility to your specific operating conditions, then our Rotary Feeder is the ideal choice.
1. Continuous and Stable Feeding
By incorporating a precisely engineered pressure-equalizing and venting structure into the design, our equipment effectively expels accumulated gas from the rotor chamber. This fundamentally resolves issues such as material jamming or flow interruption caused by gas back-pressure, ensuring a uniform and smooth supply of material to downstream processes.
2. Advanced Sealing Technology
Our equipment utilizes a multi-layer, composite sealing technology with a leakage rate of less than 0.1%. Whether operating within positive or negative pressure systems, it effectively prevents gas back-flow and dust leakage, while simultaneously minimizing material loss.
3. Long-Term Operational Reliability
Key contact components undergo wear-resistant hardening treatments—or can be optionally fitted with ceramic coatings—making the equipment particularly well-suited for conveying highly abrasive materials such as slag and fly ash.
The average service life of our units significantly exceeds industry standards, thereby substantially reducing your replacement frequency and long-term operational costs.
4. Flexible Adaptation and Customization
In addition to our standard models, we offer comprehensive customization services. From material selection (stainless steel, carbon steel, ceramic lining) and port dimensions to specific temperature/pressure ratings and explosion-proof requirements, every aspect can be optimized to align perfectly with your specific material characteristics and operating conditions.
5. Intelligent Control
The equipment supports variable frequency speed control, enabling precise, linear adjustment of the feeding rate with an accuracy tolerance of ±2%. Furthermore, its modular design ensures that routine inspections and the replacement of wear parts remain quick and effortless.
Working Principle
The rotary feeder utilizes a motor to drive an internal impeller in a constant-speed rotation, thereby executing an efficient cycle:
1. Filling: Material descends from the overhead hopper into the compartments formed by the rotating blades.
2. Sealed Conveyance: The impeller rotates within a precisely fitted housing, carrying the material through a sealed space toward the discharge outlet located below.
3. Pressure Equalization and Discharge: A lateral pressure-equalization port promptly vents the compressed gas generated by the rotation, ensuring the material flows smoothly into the downstream pipeline.
4. Continuous Cycle: This process repeats continuously, fulfilling the core functions of both uniform feeding and gas isolation, thereby serving as a reliable nexus connecting the hopper to the conveying pipeline.

FAQ
Q: What information do I need to provide when selecting equipment?
A: To ensure the best match for your needs, please provide us with the following details:
Material Characteristics: Name, particle size, density, moisture content, and corrosiveness.
Operating Conditions: Temperature, pressure, and conveying capacity.
Any Special Requirements: Such as explosion-proof features or food-grade compliance.
Our engineers will then recommend the most suitable model and configuration for you.
Q: How can I effectively prevent material jamming?
A: First, ensure that the material characteristics (such as particle size and moisture content) fall within the equipment's design parameters. Our pressure-equalizing and venting design is already capable of resolving most issues related to air-lock jamming.
For sticky materials, we can offer anti-stick impellers or heat-tracing options.
Q: Is equipment maintenance complicated?
A: It is very simple. Routine inspections (recommended every three months) covering lubrication status, seal wear, and impeller clearance are all that is required.
Our modular design makes replacing key wear parts quick and easy, significantly reducing maintenance downtime.
Q: Do you support custom non-standard solutions? What is the lead time?
A: Absolutely. Customization is one of our core services. Once the specific technical solution has been confirmed, the typical lead time for custom non-standard equipment is approximately 7–15 business days; we will maintain close communication with you throughout this process.
