Product Description

ZZ Old Craftsman Vacuum Brazed Carbide Belt Scraper for Mining Conveyor Systems
In the demanding world of mining, conveyor systems are critical for transporting ores like iron, coal, and copper. However, abrasive materials, heavy loads, and harsh environments often cause rapid scraper wear, material carryback, and costly downtime. ZZ Old Craftsman, a trusted name in mining solutions since 2014, offers vacuum brazed carbide secondary belt scrapers designed to revolutionize conveyor performance in mineral processing. Crafted with premium tungsten carbide and stainless steel using advanced HIP sintering and vacuum brazing, our scrapers deliver exceptional durability, precision, and efficiency for mining operations.
Unlike conventional induction-welded scrapers, ZZ Old Craftsman vacuum-brazed solutions provide a seamless, high-strength bond, achieving a service life 3-5 times longer and significantly reducing maintenance costs. We produce a range of scraper shapes-P type, H type, and R type-in full-scale production, alongside fully customizable designs tailored to your mineral conveyor needs. Whether handling abrasive iron ore, sticky coal, or underground mining challenges, our mining conveyor belt cleaners ensure optimal performance and cost savings.
Addressing Mining Conveyor Challenges
Mining conveyors face unique challenges:
- High Abrasion: Ores like iron and copper erode standard scrapers, requiring frequent replacements.
- Material Carryback: Sticky residues reduce belt efficiency, increasing energy costs and cleanup.
- Extreme Conditions: Dust, moisture, and temperatures from -40°C to 300°C demand robust equipment.
- Operational Downtime: Scraper failures disrupt production, impacting profitability.
ZZ Old Craftsman vacuum brazed carbide scrapers tackle these issues head-on:
- Prolonged Service Life: Outlasts induction-welded scrapers by 3-5 times, minimizing replacements.
- Enhanced Cleaning: Reduces carryback, boosting conveyor throughput and efficiency.
- Cost Efficiency: Clients report up to 40% savings in maintenance costs and 25% less downtime.
- Environmental Resilience: Excels in corrosive, dusty, and extreme-temperature mining environments.
Key Features of ZZ Old Craftsman Carbide Scrapers
Our vacuum brazed carbide belt scrapers are engineered for mining excellence:
- Superior Wear Resistance: Tungsten carbide ensures durability against abrasive ores like iron and coal.
- High-Temperature Stability: Performs reliably from -40°C to 300°C, ideal for open-pit and underground mines.
- Robust Corrosion Resistance: Resists dust, moisture, and chemicals, ensuring long-term reliability.
- Precision Engineering: Flat, smooth surfaces and precise dimensions deliver consistent scraping.
- Vacuum Brazing Superiority: Unlike induction welding, vacuum brazing creates a seamless bond, eliminating weak points and stresses. Benefits include:
- 3-5 times longer service life.
- Smoother surfaces for optimal cleaning.
- Reduced maintenance and downtime costs.
- Tailored Solutions: Customizable to match your conveyor's specifications and ore type.
Versatile Scraper Shapes for Mining Applications
ZZ Old Craftsman produces a variety of scraper shapes in full-scale production, each suited to specific mining conveyor needs:
- P Type: Commonly used for high-abrasion environments, such as iron ore processing, where its robust design ensures efficient material removal and minimal carryback on wide belts.
- H Type: Often applied in high-impact applications like coal transportation, with a reinforced structure to handle heavy loads and tough conditions.
- R Type: Typically suited for compact or specialized systems, such as underground mining conveyors, offering precision and adaptability.
Note: While these shapes are designed for the above applications, ZZ Old Craftsman can confirm specific suitability based on your conveyor system. Beyond standard models, we specialize in custom carbide scrapers, crafting any shape to meet unique requirements, such as specific ore types or conveyor configurations. Our advanced manufacturing ensures rapid delivery and consistent quality, making ZZ Old Craftsman a reliable partner for mining solutions.

Proven Success in Mining Operations
ZZ Old Craftsman vacuum brazed carbide scrapers have transformed conveyor performance in mining operations worldwide. Here are illustrative examples:
- Iron Ore Mine in Western Australia: Facing rapid scraper wear from abrasive iron ore, a large-scale operation adopted our P type scrapers. The result was a 40% reduction in maintenance costs and a 30% decrease in downtime, boosting productivity.
- Coal Handling Facility in North America: A coal processing plant struggled with material carryback, reducing efficiency. Our H type scrapers, tailored for high-impact belts, improved belt cleanliness by 35%, saving significant energy and cleanup costs annually.
- Underground Copper Mine in South America: Operating in a dusty, corrosive environment, this mine required durable scrapers for compact conveyors. Our R type scrapers, customized for their system, extended service life by 4 times compared to induction-welded alternatives, minimizing disruptions.
These examples demonstrate how ZZ Old Craftsman scrapers deliver reliability and cost savings in mineral processing.
