Mining, cement, quarrying, power generation, and bulk material handling industries all face the same challenge: conveyor belt scrapers wear out quickly when operating in highly abrasive, wet, or corrosive environments. Frequent scraper replacement leads to increased downtime, higher maintenance costs, and reduced production efficiency.
Old Craftsman Vacuum Brazed Carbide Scrapers are specifically engineered to overcome these challenges. By combining premium tungsten carbide with advanced vacuum brazing technology, they deliver exceptional wear resistance, stronger bonding, and a significantly longer service life than conventional scrapers.
1. Superior Vacuum Brazing Technology
Unlike traditional brazing methods, vacuum brazing is performed in a high-vacuum furnace where oxidation is virtually eliminated. This creates a clean, high-strength metallurgical bond between the tungsten carbide and the steel substrate.
Key advantages include:
- Stronger carbide-to-steel adhesion
- Uniform brazing layer without voids
- Excellent impact resistance
- Reduced risk of carbide tip detachment
The result is a scraper capable of withstanding continuous heavy-duty operation even under severe working conditions.
2. Outstanding Abrasion Resistance
Conveyor systems often transport highly abrasive materials such as:
- Iron ore
- Copper ore
- Coal
- Limestone
- Sand
- Clinker
- Aggregates
These materials rapidly wear ordinary steel scrapers.
Old Craftsman vacuum brazed carbide scrapers utilize premium tungsten carbide, which offers hardness several times greater than hardened steel. This exceptional hardness dramatically reduces wear, allowing the scraper to maintain its cleaning efficiency for much longer.
3. Excellent Performance Under High Impact
Harsh conveyor applications frequently involve:
- Large material lumps
- Heavy impact loading
- Material vibration
- Belt misalignment
Poor-quality brazed scrapers may crack or lose carbide inserts after repeated impacts.
Old Craftsman’s optimized vacuum brazing process evenly distributes stress across the joint, minimizing the chance of cracking or carbide separation. The scraper remains reliable even in demanding mining operations.
4. Reliable Operation in Wet and Corrosive Environments
Many conveyor systems operate outdoors where equipment is exposed to:
- Rainwater
- Mud
- High humidity
- Salt spray
- Chemical contamination
Vacuum brazing minimizes oxidation during manufacturing, resulting in a cleaner, more corrosion-resistant bond.
This helps the scraper maintain structural integrity even in challenging environments such as ports, fertilizer plants, coal terminals, and mineral processing facilities.
5. Consistent Cleaning Performance
A worn scraper leaves excessive carryback on the return belt, causing:
- Material spillage
- Belt mistracking
- Increased cleanup labor
- Premature idler wear
- Higher maintenance costs
Because the carbide edge wears much more slowly, Old Craftsman scrapers maintain an effective cleaning angle throughout their service life, delivering consistent belt cleaning performance and reducing material loss.
6. Reduced Maintenance and Downtime
Longer service life directly translates into lower operating costs.
Benefits include:
- Fewer scraper replacements
- Less maintenance labor
- Reduced conveyor downtime
- Lower spare parts inventory
- Improved production efficiency
For large mining operations running multiple conveyors 24/7, these savings can be substantial over the equipment’s lifecycle.
7. Suitable for a Wide Range of Industries
Old Craftsman Vacuum Brazed Carbide Scrapers are widely used in:
- Mining
- Quarrying
- Cement plants
- Coal handling
- Steel mills
- Power generation
- Aggregate production
- Ports and terminals
- Recycling facilities
They perform reliably wherever conveyor belts are subjected to severe wear and demanding operating conditions.
