RZS Series Asphalt Mixing Plant: China Suppliers Factory for High-Quality Thermal Regeneration Equipment

In the realm of asphalt pavement renovation and maintenance, a significant quantity of Reclaimed Asphalt Pavement (RAP) is produced. To promote resource recycling and reuse, thermal regeneration mixing equipment has been introduced. This innovative technology first heats the RAP and then fully integrates it with new asphalt mixtures. The RZS series represents a factory mixed hot regeneration process and offers the flexibility of heating in either a forward or reverse flow. Originating from Europe, this technology is capable of incorporating a substantial proportion of recycled materials, achieving discharge temperatures of 110 to 160 degrees Celsius. Our equipment is extensively utilized in China, particularly in municipal road engineering and surrounding asphalt pavement projects, making it ideal for the production of middle and lower layer asphalt mixtures. As a trusted supplier and factory, we are committed to providing high-quality thermal regeneration solutions for efficient asphalt recycling.
