Vacuum brazed carbide belt cleaners (also called scrapers or secondary cleaners) significantly improve performance in mining conveyor systems by delivering superior durability, cleaner belts, reduced carryback, and lower overall operating costs compared to traditional options.
What Is a Vacuum Brazed Carbide Belt Cleaner?
These are secondary belt scrapers installed after the head pulley to remove residual material (carryback) from the return side of the conveyor belt. They feature tungsten carbide tips or blades bonded to a stainless steel base (often 316L) using vacuum brazing technology, combined with HIP (Hot Isostatic Pressing) sintering for the carbide itself.
- Tungsten carbide provides extreme hardness (up to 92.5 HRA), excellent abrasion resistance, and good performance in high-impact or corrosive conditions.
- Common designs include P-type (for high-abrasion materials like iron ore), H-type (for high-impact like coal), and R-type (compact for underground or space-limited setups). They are customizable for belt widths from 650–2400 mm and speeds up to ~6.5 m/s.
Improve conveyor efficiency and reduce material carryback with our high-performance Vacuum Brazed Carbide Belt Cleaner, specifically engineered for demanding mining environments. Designed using advanced vacuum brazing technology, this cleaner delivers superior bonding strength between the tungsten carbide tips and the steel base, ensuring exceptional durability and long service life under extreme conditions.
Unlike traditional belt cleaners, this solution offers enhanced wear resistance and consistent cleaning performance, even when handling abrasive ores, wet materials, or high-speed conveyor systems. The carbide blades maintain sharp edges for longer periods, minimizing maintenance frequency and reducing operational downtime.
Its robust structure and optimized blade geometry ensure maximum contact with the conveyor belt, effectively removing residual materials and preventing buildup. This results in improved material flow, reduced spillage, and a cleaner, safer working environment.
