Tungsten carbide conveyor belt scrapers are essential components in material handling systems, designed to efficiently clean conveyor belts and maintain optimal system performance. This guide covers everything you need to know about these durable, high-performance scrapers.
What Are Tungsten Carbide Conveyor Belt Scrapers?
- Heavy-duty cleaning blades made from tungsten carbide material
- Designed to remove sticky, wet or dry material from conveyor belts
- Mounted at strategic points along the conveyor system (typically at the head pulley)
- Available in various configurations for different applications
Benefits of Tungsten Carbide Scrapers
- Exceptional Wear Resistance – Last up to 10 times longer than standard polyurethane scrapers
- Improved Cleaning Efficiency – Maintain consistent cleaning performance throughout their lifespan
- Reduced Maintenance Costs – Fewer changeouts required compared to other materials
- Corrosion Resistance – Ideal for wet or chemically aggressive environments
- High Temperature Tolerance – Perform well in both hot and cold applications
Types of Tungsten Carbide Scrapers
- Primary Scrapers: First line of defense, removing bulk material
- Secondary Scrapers: Fine cleaning after the primary scraper
- Pre-Cleaners: Initial material removal before primary scrapers
- Specialty Designs: Custom shapes for specific applications or belt types
Key Applications
- Mining and mineral processing
- Cement and aggregate plants
- Power generation (coal handling)
- Food processing
- Recycling facilities
- Wood and paper products
- Chemical processing
Installation Considerations
- Mounting Angle: Typically 30-45 degrees to the belt surface
- Contact Pressure: Must be properly adjusted to balance cleaning effectiveness with belt wear
- Positioning: Usually installed at the discharge point where material tends to stick
- Hardware: Requires sturdy mounting brackets and tensioning systems
Maintenance Best Practices
- Regularly inspect for wear (check for grooves or uneven wear patterns)
- Monitor belt condition for signs of excessive wear
- Keep mounting hardware tight and properly adjusted
- Clean accumulation areas to prevent material buildup
- Replace scrapers before they become completely worn
Cost Considerations
While tungsten carbide scrapers have a higher upfront cost than alternatives, their extended service life typically results in:
- Lower total cost of ownership
- Reduced downtime for changes
- Less frequent purchases
- Lower labor costs for maintenance
Selecting the Right Scraper
Consider these factors when choosing:
- Belt type and speed
- Material characteristics (abrasiveness, moisture content)
- Operating environment (temperature, chemicals)
- Conveyor configuration
- Cleaning requirements
Conclusion
Tungsten carbide conveyor belt scrapers offer superior performance and longevity for demanding material handling applications. By selecting the appropriate design and maintaining them properly, operations can achieve cleaner belts, reduced carryback, and lower maintenance costs over the long term.
