Abrasion Resistant Vacuum Brazed Carbide Belt Cleaner for Mining Applications

Abrasion-resistant vacuum-brazed carbide belt cleaners (also called scrapers or secondary cleaners) are specialized conveyor belt cleaning tools designed for harsh mining and bulk-material-handling environments. They use tungsten carbide tips or blades metallurgically bonded to a steel (often stainless steel) base via vacuum brazing.

Key Features and Advantages

Vacuum brazing process — Creates a strong metallurgical bond between the carbide and steel substrate. This improves impact resistance, reduces the risk of tip detachment under vibration or shock loads, and outperforms simpler mechanical fastening, adhesive, or basic welding methods.
High abrasion resistance — Tungsten carbide tips typically reach hardness levels of HRA 88–92.5 (depending on grade, e.g., YG8/YG10/YG15 or similar). They handle highly abrasive ores, coal, aggregates, and wet/sticky materials far better than polyurethane or rubber blades.
Service life — Commonly claimed to last 3–5 times longer than conventional polyurethane or rubber cleaners in mining conditions, leading to lower maintenance frequency, reduced downtime, and better long-term cost of ownership.
Cleaning performance — Maintains a sharp, consistent edge for effective removal of carryback material on the return side of the belt (secondary cleaner position) or as primary cleaners. Optimized blade geometry aims to minimize belt wear while maximizing contact.
Durability extras — Resistant to impact, corrosion (with stainless bases such as 316L), and a range of operating temperatures. Designs are often customizable for different belt widths, speeds, and material types (e.g., high-abrasion vs. high-impact grades).

Typical Applications

Primarily used in mining conveyor systems (open-pit and underground) for iron ore, copper, coal, and other minerals. Also applied in cement plants, quarries/aggregates, steel mills, coal handling, ports, and other abrasive bulk-material operations.

How Carbide Belt Cleaners Reduce Conveyor Downtime

A poorly performing belt cleaner can create several problems:

Excessive material buildup
Increased conveyor belt wear
Damaged rollers and pulleys
Higher housekeeping costs
Reduced production efficiency

By installing abrasion resistant carbide belt cleaners, operators can maintain cleaner conveyor belts and improve overall system reliability.

The improved cleaning efficiency also reduces the amount of material returned to the conveyor system, helping protect downstream equipment and improving workplace safety.
