Anti-slip conveyor belts prevent rollback, spillage, dust, and downtime in chemical, mining, port, and bulk material lines. With higher incline capacity, better grip, and chemical-resistant rubber, they improve safety, efficiency, and overall conveying reliability.

Underground coal mines face serious risks from coal dust and methane gas, where sparks or airborne dust can cause fires and explosions. To address these hazards, specialized conveyor belts with dust‑free and explosion‑proof features are essential. Hengyi’s flame‑retardant mining belts are designed to reduce risks at the source, using three core protective layers: strong flame resistance that self‑extinguishes quickly, anti‑static properties to prevent sparking, and a compact structure that minimizes dust leakage. Some models also include sidewalls for better containment. These belts are widely used in main haulage roadways, mining faces, coal bunkers, and inclined conveying lines, providing enhanced safety and stability. When selecting a mining belt, it is important to choose certified products, match the belt type to site conditions (PVC for dry areas, PVG for wet conditions), and avoid low‑quality alternatives that may create hidden dangers. Hengyi’s tested and reliable belts help mines maintain safer, more efficient operations while protecting workers and reducing potential losses.

Heavy nylon conveyor belts, widely used in mining, ports, and building materials, are constructed with multiple layers of high‑strength nylon fabric and abrasion‑resistant rubber to handle heavy loads, impact, and harsh conditions. However, poor operation and maintenance can lead to frequent downtime and increased costs. Key strength grades include NN100 to NN500, with total tensile strength determined by the number of plies. Hengyi belts offer strong inter‑ply adhesion and 20–50% longer service life than standard products. Common causes of failure include overloading, misalignment, improper startup, and unsuitable environmental resistance. Proper use—such as controlling load, ensuring alignment, reducing impact, and selecting appropriate cover materials—can prevent over 80% of unexpected damage. Regular maintenance, including daily cleaning, weekly tension checks, monthly wear inspections, quarterly splice reviews, and annual professional testing, helps extend belt life by 20–30% and control long‑term expenses. Hengyi provides reliable, durable, and environmentally friendly conveyor belt solutions, along with technical support for selection and maintenance.

Hengyi’s flame resistant conveyor belts are essential for safety in high‑risk industries such as coal mining, power generation, metallurgy, and chemical processing. Designed with special PVC/PVG materials and a solid woven structure, these belts prevent flame spread and reduce fire hazards, especially in underground mines. Key features include reliable flame resistance, stable anti‑static performance to minimize explosion risks, and strong tensile and tear resistance for heavy‑load durability. PVG belts offer higher transverse strength, better tear resistance, and improved performance in wet or inclined conditions. The fully impregnated structure also provides excellent abrasion and corrosion resistance, ensuring long service life in harsh environments. Compared with heavy steel cord belts, Hengyi’s lightweight solid woven belts reduce energy consumption and equipment costs, and are environmentally recyclable. Hengyi provides customized solutions and technical support to meet specific mining requirements.

Corrugated sidewall conveyor belts address major limitations of standard flat belts in bulk material handling. Traditional belts struggle with steep angles, space constraints, spillage, rollback, and dust, especially in mining, ports, cement, and metallurgy. Sidewall belts use a reinforced base, tall flexible sidewalls, and optional cross cleats to create enclosed “pockets,” enabling inclines from 30° to 90° and even vertical lifting. This design drastically reduces material loss, dust emissions, and space requirements while boosting throughput by 20–50% and cutting installation and operational costs. Hengyi’s sidewall belts feature high‑quality polyester cores for durability, minimizing downtime and improving overall conveying efficiency in harsh industrial environments.

Heat resistant conveyor belts are essential in industries such as cement, steel, metallurgy, and coking, where materials like clinker, sintered ore, and hot coke often reach 300–800℃. Ordinary belts quickly age, crack, or fail under these conditions, leading to production downtime, material spillage, and safety risks. Heat resistant belts are specifically engineered to withstand high temperatures, ensuring continuous operation, reducing maintenance costs, and improving workplace safety. High-temperature environments pose several challenges, including rapid rubber aging, carcass deformation, and potential fire hazards. Professional heat resistant belts mitigate these risks through specialized materials and structures. Hengyi’s belts cover the full range of heat resistance grades (T1–T4), using materials such as SBR and EPDM, with maximum operating temperatures from 150℃ up to 400℃ for short-term use. The belts feature multi-layered cores, strong adhesion, and resistance to heat, chemicals, and wear, offering a service life 2–4 times longer than standard belts. These belts are widely used in cement clinker transport, steel and metallurgy processes, coking operations, and other high-temperature material handling applications. Hengyi provides customized solutions and has supplied products to large enterprises domestically and internationally, helping customers achieve safer and more efficient production.

Selecting the right conveyor belt for mining is crucial for productivity, safety, and cost control. Many operational issues stem from mismatched belt specifications rather than poor quality. Key considerations include understanding the material being conveyed—such as coal, ore, or crushed stone—and its characteristics, including particle size and impact. Environmental factors like underground or open-pit settings, moisture, dust, and temperature also influence belt performance. Matching the belt structure to the conveyor system is essential. This involves choosing between steel cord or fabric carcasses, selecting the appropriate tensile strength based on distance and lift, and determining cover thickness for abrasion and impact resistance. Special properties like fire resistance (required underground), abrasion resistance, and heat resistance should also be evaluated. Finally, conveyor layout, installation quality, splicing, and regular maintenance significantly affect belt life. Hengyi provides abrasion-resistant and fire-resistant mining belts compliant with international standards, ensuring reliable performance across diverse mining applications.
