Challenges in Handling Adhesive Powder Substances
- Adhesive powders, due to their cohesive nature, often present challenges such as:
- Material build-up
- Clogging
- Inefficient flow
leading to extended processing times and equipment wear.
- Rotary valves may not be suitable for these materials as they are prone to blockages, especially at discharge points.
- Adhesive powders can adhere to the internal surfaces of the valve, causing inefficiencies in metering and feeding processes.

Specialized Rotary Valves for Sticky Materials ( Scraper Type Valve )
Rotary valves designed for adhesive powders incorporate features to overcome these challenges. For instance, scraper-type rotary valves are equipped with internal scrapers that continuously clean the surfaces of the valve, preventing material build-up and ensuring consistent flow. These valves are particularly effective for handling sticky materials, reducing the risk of clogging and maintaining an uninterrupted process flow. The use of these valves can significantly reduce maintenance requirements and operational downtime, allowing for more efficient handling of adhesive substances.
Key Features of Rotary Valves for Adhesive Powders
- Precision Metering: One of the main functions of rotary valves is to meter material from a supply into downstream processes. For adhesive powders, precision is crucial to avoid excess material flow, which can worsen sticking and build-up.
- Scraper Mechanisms: The scraper type rotary valve remove material from the valve surfaces during operation. This prevents accumulation and ensures that the valve remains operational for extended periods without the need for frequent cleaning.
- Sealing and Leakage Prevention: The Scraper rotary valves are designed to prevent leakage of powder or granules, which is critical for both product quality and environmental control.
Applications of Rotary Valves for a wide range of Industries:
Rotary valves designed for adhesive powders find applications in a variety of industries:
- Food Processing: Rotary valves are used to control the flow of dry ingredients such as flour, sugar, and spices in food processing plants.
- Chemical Industry: Rotary valves manage the flow of granular and powdered chemicals, enabling smooth transitions between different processing stages.
- Plastic and Polymer Processing: Rotary valves facilitate the movement of plastic pellets or granules in manufacturing processes. They enable precise dosing of colorants and additives during polymer production.
Reducing Downtime and Maintenance
One of the major advantages of using Scraper rotary valves tailored for adhesive powders is the significant reduction in downtime. Traditional valves, when handling sticky materials, require frequent cleaning and maintenance to remove accumulated material. This not only interrupts the production process but also increases labor and maintenance costs.
Scraper-type rotary valves minimize the need for manual intervention. As a result, the process can run continuously, with minimal interruptions for cleaning or maintenance. This improves overall productivity and reduces operational costs. Moreover, by ensuring consistent material flow, these valves also contribute to better product quality and more efficient downstream processes.
Conclusion
Rotary valves are essential components in the efficient handling of adhesive powders.

- Reduce Downtime
- Improve material flow
- Enhance process efficiency
