The V-type polyurethane return belt scraper is a dedicated cleaning device for the non-working surface of belt conveyors. It is installed in front of the tail bend pulley, designed to remove dust, fine particles, slime and sticky materials adhering to the return belt. It effectively protects pulleys and belts, and prevents belt deviation and abnormal wear.
Product Advantage
1. Definition & Application
• Installation Position: Ahead of the tail pulley and tensioning device, above the return belt (non-working side).
• Function: Removes residual materials on the return belt to prevent materials from winding around pulleys, which would otherwise cause belt deviation, wear of pulley lagging, material accumulation on idlers, increased energy consumption and potential safety hazards.
• Application Scenarios: Widely used in coal mines, power plants, ports, metallurgy, building materials and other industries for conveying dusty and sticky materials. Applicable belt width: 500–2400 mm; Maximum belt speed: ≤ 4.6 m/s.
2. Main Advantages
• Thorough cleaning: V-shaped flow guiding design eliminates material residue in the middle area.
• Belt protection & long service life: Flexible polyurethane material avoids belt damage, with outstanding wear and corrosion resistance.
• Automatic adaptation: Real-time compensation for blade wear ensures stable fitting and low maintenance.
• High safety: Flame-retardant and anti-static performance makes it suitable for underground and flammable & explosive environments; simple structure for quick installation.
• Cost reduction: Reduces belt deviation and component wear, cutting downtime and maintenance costs.
