Global Benchmark for Solidification & Cooling of Molten Materials
Founded in 1843, Berndorf Band Group from Austria is a global leader in precision steel belts and industrial cooling systems. It supplies core equipment for cooling and solidifying molten materials for chemical, fertilizer, energy and other industries, renowned for high precision, outstanding reliability and long service life.
Custom-designed for molten materials including sulfur, paraffin wax, resin, oil chemicals, fertilizers, asphalt and organic intermediates. It realizes continuous cooling, solidification and forming of high-temperature liquid feedstock into flakes or pellets, widely applied in fine chemical industry, coal chemical industry, fertilizer production and polymer material sectors.
• Special adaptation: closed structure for processing toxic and odorous materials with environmental protection and safety guaranteed
1.High-precision stainless steel belt: The core carrier, independently developed and manufactured in-house. Featuring excellent flatness, superior thermal conductivity, corrosion resistance and fatigue resistance, it achieves a service life of over 10 years.
2.Single/Double Steel Belt Cooling Main Unit:
3. BernDrop® Intelligent Feeding System
4. Discharging & Post-processing Unit
5. Automatic Control System
Feasible variable frequency speed regulation, three-stage temperature control, steel belt tracking and tensioning, enabling real-time adaptation to material characteristics and production capacity.
Molten material → Evenly distributed onto the constant-speed steel belt via BernDrop® feeder → Cooling water sprayed on the back of the belt realizes indirect heat exchange for rapid cooling and solidification → Material automatically detaches at the discharge end through belt reversal → Post-processing to obtain finished products; fully continuous automatic operation throughout the process.
• Efficient heat exchange & uniform cooling: Thin steel belt with excellent thermal conductivity plus zoned spray cooling. Heat transfer efficiency far exceeds traditional drum flakers. Multi-section temperature control prevents cracking and deformation of products.
• Global resources & local response: The Group operates an integrated service network with more than 10 subsidiaries worldwide. Since 2002, our local service team in China delivers efficient and convenient full-cycle service for customers.
• Sulphur Pastillation: Single steel belt cooler, capacity 20 t/h, uniform pellets and low dust, ideal for large-scale sulphuric acid & fertilizer production lines.
• Resin / Paraffin Wax: Single / double steel belt cooler for high-viscosity materials, uniform cooling without adhesion, improving efficiency of downstream processing.
• Sulphur-based Compound Fertilizer: BernDrop® feeding system + single steel belt cooling. Precise particle size and high particle strength, meeting requirements of high-end fertilizer production.
