Which type of asphalt crusher is best to choose? Asphalt crushing achieves remarkable results with asphalt tooth roller crusher, whose advantages are primarily reflected in the following aspects:
asphalt tooth roller crusher
1. Precise particle size control and uniform output
By adjusting the roller tooth gap (typically adjustable between 5-30mm), the asphalt tooth roller crusher precisely controls output particle size. This ensures uniform particle size of the crushed asphalt aggregate, meeting the gradation requirements for recycled mix. The crushed asphalt can be directly used in plant-mixed hot recycling, with the blending ratio increased to 45%, while maintaining road performance that meets specification standards. Additionally, its shear crushing principle avoids the over-crushing issues common in traditional equipment (such as jaw or hammer crushers), resulting in a needle and flake particle content below 10% and low fines production.
2. High efficiency and energy savings, low operating costs
The asphalt tooth roller crusher employs a low-pressure crushing principle, reducing energy consumption by over 30% compared to traditional equipment. Its multi-tooth synergistic action distributes crushing pressure, making it suitable for continuous operation with an hourly processing capacity of 50-200 tons (depending on model). Simultaneously, the enclosed structure and dust collection system design keep dust emission concentrations below 20mg/m³, meeting environmental requirements.
3. Anti-Adhesion Design, Strong Adaptability
Asphalt exhibits high stickiness, causing frequent blockages in conventional equipment. The double-tooth roller crusher features wear-resistant alloy roller teeth surfaces and an automatic cleaning mechanism that effectively minimizes material adhesion, ensuring stable operation. Its gentle shearing and squeezing action prevents asphalt from overheating and softening due to high-speed impact, thereby avoiding re-agglomeration after crushing.
4. Simple Maintenance, High Durability
The equipment features a simple structure. Wear parts (such as roller teeth) can be replaced without disassembling the entire machine, reducing downtime. High-manganese steel or alloy roller teeth extend service life, making it particularly suitable for milled asphalt containing hard aggregates.
5. Dual Benefits of Environmental Sustainability and Cost Efficiency
The twin-tooth roller crusher reduces demand for new materials through resource recycling, lowering production costs. For instance, one case study demonstrated increased recycled aggregate utilization, eliminating secondary screening processes and significantly reducing overall costs. Additionally, its low-noise and low-dust characteristics align with green construction practices.
