DPP1250 Kevlar Conveyor Belt – High-Performance Aramid Belt for Industrial Material Handling

The DPP1250 Aramid conveyor belt is engineered for heavy-duty industrial applications where reliability, durability, and safety are paramount. Designed with high-strength aramid fiber carcass technology, this belt delivers exceptional tensile strength, minimal elongation under load, and superior resistance to abrasion, impact, and environmental stressors. It’s ideal for continuous operation in demanding sectors such as mining, power generation, metallurgy, cement production, and chemical processing.

Key features include a minimum longitudinal tensile strength of 1250 N/mm, consistent transverse strength of 150 N/mm, and a maximum 10% load elongation of just 0.5%, ensuring stable performance even under high tension. The belt's standard cover rubber thickness of 6+2 mm offers excellent protection against wear and tear while maintaining flexibility. With a total thickness of 11.6 mm and a weight of approximately 11.3 kg/m², the DPP1250 balances robustness with manageable handling characteristics—making it suitable for both fixed and mobile conveying systems.

This advanced conveyor solution is especially suited for environments involving abrasive materials, extreme temperatures, or hazardous conditions. Its flame-retardant and anti-static properties make it an essential component in coal mine operations, where fire prevention and explosion mitigation are critical. In metal extraction processes—including iron, copper, and gold mines—the belt resists sharp mineral edges and repeated mechanical stress, minimizing downtime and maintenance costs. For thermal power plants, its heat resistance ensures safe transport of hot coal without deformation or degradation. In nuclear facilities, corrosion-resistant and non-magnetic variants provide compliance with stringent safety standards for fuel handling. Similarly, steel mills benefit from its ability to withstand high-temperature raw materials like sintered ore and billets, while glass factories rely on its low elongation and smooth surface to prevent breakage during fragile product transit.

In the building materials sector, the DPP1250 excels in cement kilns and limestone processing lines, offering long service life despite constant exposure to abrasive powders and elevated temperatures. In chemical industries such as fertilizer and plastic manufacturing, its resistance to corrosive substances like urea, ammonium salts, and plastic granules ensures uninterrupted production cycles. The belt’s low friction coefficient also reduces material buildup, improving efficiency and reducing cleaning frequency across multiple applications.

Industry professionals consistently highlight the DPP1250’s ability to reduce unplanned stoppages and lower lifecycle costs compared to conventional belts. Its structural integrity allows for extended operational periods between replacements, which translates into significant savings in labor, downtime, and spare parts inventory. Operators report improved system stability, fewer misalignments, and enhanced safety due to consistent tension control and reduced slippage—particularly valuable in automated or remote-controlled conveyance setups.

Common questions often revolve around installation compatibility, temperature limits, and maintenance requirements. The DPP1250 is designed for standard pulley configurations and can operate reliably within a range of -20°C to +80°C, depending on the cover rubber formulation. Routine inspection for edge wear, splice integrity, and tension balance is recommended every 3–6 months, depending on usage intensity. Unlike traditional belts that degrade quickly under heavy loads or abrasive media, the DPP1250 maintains performance consistency over thousands of hours of service, making it a cost-effective investment for modern industrial logistics.
