Conveyor systems are essential in industries such as mining, manufacturing, and logistics, facilitating the smooth movement of bulk materials. However, one of the biggest challenges in conveyor operations is material spillage, which leads to waste, dust emissions, and increased maintenance costs. This is where conveyor belt skirting comes into play—an essential component designed to contain materials, reduce dust, and improve efficiency.
In this article, we’ll explore the importance of conveyor belt skirting, its benefits, the different types available, and innovative solutions like the AirScrape® from ScrapeTec Trading.
What is Conveyor Belt Skirting?
Conveyor belt skirting is a sealing system installed along the edges of conveyor belts to prevent material spillage and dust escape. It acts as a barrier, ensuring that materials stay on the belt while also minimizing contamination in surrounding areas.
Traditional skirting systems rely on rubber strips that press against the conveyor belt, creating a seal. However, these conventional methods often cause belt wear, increased friction, and require frequent maintenance.
Innovative skirting solutions, such as non-contact air-based systems, are revolutionizing the industry by reducing wear and improving efficiency.
Benefits of Conveyor Belt Skirting
1. Prevents Material Spillage
One of the primary functions of conveyor belt skirting is to contain bulk materials within the belt. Without proper skirting, fine materials such as coal, sand, or cement can escape, leading to product loss and contamination. Skirting ensures that all materials are properly directed to the discharge point.
2. Reduces Dust Emissions
Dust generation is a major concern, especially in industries handling fine or hazardous materials. Skirting helps create an enclosed system, preventing dust from escaping and improving air quality in workplaces. This is crucial for compliance with health and safety regulations.
3. Minimizes Conveyor Belt Wear
Traditional rubber skirting solutions tend to press tightly against the conveyor belt, leading to abrasion and premature wear. This not only shortens the lifespan of the belt but also increases maintenance costs. Modern skirting systems, such as non-contact air-based skirting, eliminate friction and extend belt longevity.
4. Enhances Energy Efficiency
Friction between traditional skirting and the belt increases motor load, leading to higher energy consumption. By reducing or eliminating contact, innovative skirting systems help conveyors operate more efficiently, reducing power usage and operational costs.
5. Reduces Maintenance and Downtime
Frequent adjustments and replacements of traditional skirting systems add to operational costs and downtime. Advanced skirting solutions, such as self-adjusting or air-based systems, minimize the need for manual intervention, improving productivity.
Types of Conveyor Belt Skirting
There are different types of conveyor belt skirting available, each designed for specific industrial needs.
1. Traditional Rubber Skirting
- Made from durable rubber materials
- Requires frequent adjustments
- Causes friction and belt wear
- Cost-effective but high maintenance
2. Polyurethane Skirting
- More wear-resistant than rubber
- Lower friction, reducing belt damage
- Longer lifespan but still requires periodic maintenance
3. Air-Based Skirting (Non-Contact Systems)
- Uses air pressure to create a floating seal
- Eliminates friction and belt wear
- Self-adjusting, reducing maintenance
- Improves dust suppression and spillage control
One of the most advanced air-based skirting solutions is AirScrape, developed by ScrapeTec Trading.
AirScrape – The Future of Conveyor Belt Skirting
AirScrape is a revolutionary non-contact skirting system that enhances conveyor performance by eliminating material spillage and dust emissions without touching the belt.
Key Features of AirScrape
- Non-Contact Design – Unlike traditional skirting, AirScrape® does not press against the belt, reducing friction and wear.
- Airflow Technology – The system uses air suction to keep dust and fine particles contained, improving environmental conditions.
- Durability – Made from high-quality materials resistant to abrasion and impact.
- Easy Installation & Maintenance – No frequent adjustments are required, reducing downtime.
- Energy-Efficient – Lowers energy consumption by reducing belt drag and motor load.
How AirScrape Works
Installed alongside the conveyor belt, but without direct contact
The curved design creates airflow, pulling dust and materials back onto the belt instead of letting them escape.
As the belt moves, the negative pressure created by AirScrape® keeps materials contained, minimizing spillage.
This innovative solution is widely used in mining, cement plants, ports, and bulk material handling industries, providing a cost-effective and long-term solution to conveyor skirting challenges.
Choosing the Right Conveyor Belt Skirting
When selecting a skirting system, consider the following:
- Material Type – Choose a skirting material suitable for the abrasiveness and moisture content of your bulk materials.
- Belt Speed & Load – Higher belt speeds require more efficient skirting solutions like AirScrape.
- Environmental Regulations – Industries with strict dust control requirements should opt for non-contact skirting.
- Maintenance Needs – If frequent adjustments are a concern, choose self-adjusting or air-based skirting systems.
Conclusion
Conveyor belt skirting is a vital component in improving material handling efficiency. By preventing spillage, reducing dust emissions, and minimizing belt wear, skirting solutions help industries cut costs and enhance workplace safety. While traditional rubber and polyurethane skirting are still widely used, advanced non-contact solutions like AirScrape offer superior performance, longer lifespan, and lower maintenance requirements.
For businesses looking to optimize conveyor efficiency, reduce downtime, and enhance sustainability, investing in high-quality skirting solutions is a game-changer. Explore AirScrape from ScrapeTec Trading for a cutting-edge solution tailored to your industry’s needs.
