Reclaimed Asphalt Pavement

In the era of road rehabilitation and green construction, the recycling and reuse of reclaimed asphalt pavement (RAP) has become a core industry trend. However, traditional crushing equipment often relies on “brute force impact,” which easily fractures the hard aggregates within the milling material. This not only generates excessive dust but also damages the original aggregate gradation, significantly compromising the performance of recycled asphalt mixtures.

Addressing this industry pain point, Huashengming Heavy Industry has introduced a double-tooth roll crusher solution specifically engineered for asphalt milling material. Centered on “flexible crushing,” it strikes the perfect balance between “liberation” and “protection,” giving every ton of milling material a new lease on life.

Flexible Shearing Technology Preserves Aggregate Gradation

The Huashengming double-tooth roll crusher abandons traditional impact crushing in favor of a low-speed, high-torque “shearing + tensile + squeezing” principle. This gentle, “kneading” crushing force precisely separates asphalt agglomerates at their bonding points, preserving the original particle size distribution, angularity, and surface texture of the aggregates. This approach not only prevents over-crushing but also ensures that the recycled material possesses excellent mechanical properties, fully meeting the construction requirements of high-grade asphalt pavements.

Patented Wear-Resistant Rollers Eliminate “Material Build-Up and Clogging”

During crushing, asphalt material tends to soften and adhere due to frictional heat. The Huashengming crusher features high-chromium manganese steel (or rare metal alloy) roller shells, combined with nationally patented wear-resistant materials and specially designed tooth profiles (such as wolf-tooth and wave-tooth patterns). The low-speed operation effectively prevents asphalt from sticking to the rollers and causing blockages. Even when processing milling material with certain moisture and impurities, the equipment maintains smooth output with well-shaped particles.

Intelligent Hydraulic Protection Ensures Continuous, Efficient Production

Road milling material often contains tramp metal such as iron pieces and rebar. The Huashengming double-tooth roll crusher is equipped with an advanced hydraulic automatic release system and dual overload protection. When encountering hard objects, the rollers automatically retract to increase the gap, expel the foreign material, and then reset automatically—completely eliminating jamming and spindle seizure. Combined with an intelligent PLC control system, the equipment can operate unattended, significantly reducing labor costs and ensuring 24/7 continuous, stable production.

Modular Customization Precisely Matches Production Requirements

From small to medium-sized municipal maintenance projects to large-scale recycling mixing plants, Huashengming offers a full range of double-tooth roll crushers with capacities from tens to hundreds of tons per hour (including models such as 600×750 and 900×900). We support modular design integrating screening and crushing, allowing flexible adjustment of the discharge gap according to customer requirements for finished product sizes (such as 0-7mm, 7-15mm, and 15-20mm)—truly “customized to your needs.”

Choosing the Huashengming double-tooth roll crusher means not only selecting a highly efficient piece of equipment but also pursuing a path to asphalt recycling profitability characterized by “low over-crushing, high yield, and low operating costs.”
