Strudex Dual-Hardness Belt Cleaner: Superior Cleaning for Sticky Material Without Belt Damage

Effective belt cleaning is one of the most critical yet overlooked aspects of conveyor system performance. For operations handling sticky materials – such as wet ore, clay, fine coal, cement, or aggregates with high moisture content – standard belt scrapers often fall short. Material carryback leads to belt misalignment, increased maintenance costs, and safety hazards. Strudex has engineered a solution specifically for these demanding conditions: the Strudex Dual-Hardness Belt Cleaner.

Designed for Sticky Material – Where Conventional Scrapers Fail

Sticky material presents unique challenges. It adheres firmly to the belt surface after discharge, resisting single‑hardness scrapers. Traditional metal blades may remove some carryback, but they damage the belt cover and splice. Polyurethane or standard rubber scrapers either wear too quickly or fail to provide sufficient cleaning pressure.

The Strudex Dual‑Hardness Belt Cleaner is purpose‑built for sticky applications. Whether you are transporting wet iron ore, bauxite, phosphate, or dewatered tailings, our scraper delivers consistent, high‑efficiency cleaning while protecting your belt investment.

Key Technology: Dual‑Hardness Scraper Blade

At the heart of the cleaner is our innovative dual‑hardness polyurethane/rubber composite blade. Unlike homogeneous scrapers, our blade combines two distinct material zones in one integrated design:

1. Rigid Base – Stable Mounting for Consistent Pressure

The base layer of the blade features a higher durometer (hardness) rating. This rigid foundation ensures the scraper maintains stable contact pressure across the entire belt width, even under heavy load or vibration. It resists deformation and provides the mechanical strength needed to keep the blade properly positioned against the belt. Proper mounting stability directly translates to more effective cleaning and longer blade life.

2. Soft Tip – Efficient, Non‑Damaging Cleaning

The working edge – the part that contacts the belt – is made of a specially formulated softer durometer material. This soft tip flexes slightly to conform to the belt surface, wiping away sticky material without gouging or scratching the rubber cover. Because the tip is non‑abrasive, it eliminates the risk of splice damage – a common problem with metal scrapers or misaligned hard blades. The result is a clean belt without premature wear or costly belt replacements.

Outstanding Benefits of Strudex Dual‑Hardness Belt Cleaner

✓ Excellent Wear Resistance – Outlasts Traditional Scrapers

Thanks to our advanced polyurethane compound and dual‑hardness construction, the Strudex scraper significantly outlasts conventional scrapers. Field tests show up to 3–5 times longer service life compared to standard rubber blades or metal scrapers in sticky material applications. Longer wear life means fewer blade changes, reduced spare parts inventory, and most importantly – less downtime for your conveyor system.

✓ Gentle on Belts – No Metal Contact, No Splice Damage

Metal scrapers may seem aggressive, but they cut into belt covers, accelerate splice failure, and create grooves where material builds up again. Our dual‑hardness blade contains no metal contact points. The soft tip glides over mechanical fasteners and splices without catching or tearing. This feature is especially valuable for belts with vulcanized or mechanical splices, as it preserves belt integrity and extends overall belt life.

✓ Excellent Cleaning Efficiency for Sticky Materials

The combination of rigid base and soft tip delivers the optimum balance: enough pressure to dislodge adhered material, yet compliant enough to follow belt contours. The blade effectively removes carryback from the belt surface, discharge chute, and return rollers, keeping your entire conveyor system cleaner and safer. Reduced carryback also minimizes dust and spillage, supporting a cleaner working environment.

Applications

The Strudex Dual‑Hardness Belt Cleaner is ideal for:

- Mining and mineral processing (wet ores, copper concentrate, iron ore fines)

- Cement and aggregate plants (moist clay, sand)

- Coal preparation plants (fine wet coal)

- Any conveyor transporting sticky, cohesive, or high‑moisture bulk materials

Installation and Maintenance

Our belt cleaner is designed for easy installation on most conveyor systems. It is available in multiple widths and mounting configurations (primary and secondary positions). The blade can be replaced quickly without special tools, further reducing downtime. For operators seeking a low‑maintenance, high‑performance belt cleaning solution for sticky materials, Strudex offers the perfect answer.
