III. Basic Consideration Indicators to Compare Asphalt Milling Teeth

When selecting asphalt milling teeth, it's essential to consider multiple performance indicators, which can be categorized into three main areas: Operational Performance, Expected Longevity, and Premature Failure Resistance. Here's an explanation of how these indicators function in practice and the issues they address:

• Capabilities to Assess:
  • Rotation Rate: Refers to the speed and efficiency at which the milling teeth rotate as they contact the surface material. A higher rotation rate helps distribute wear evenly across the teeth, enhancing cutting efficiency.
  • Cutting Force Retention: Maintaining strong cutting force is crucial for the effective grinding of tough materials, ensuring consistent performance throughout the operation.

2. Expected Longevity

• Capabilities to Assess:
  • Tip Durability: The durability of the carbide tips is the most critical factor affecting the lifespan and effectiveness of milling teeth when compared to well-designed teeth. High-quality, durable tips ensure a longer service life and sustained cutting performance, reducing the frequency of replacements and downtime.

3. Premature Failure Resistance: This is mostly due to the teeth' partial wear caused by rotation failure.

• Capabilities to Assess:
  • Deforming Resistance: The ability to resist deformation under operational stress is essential for maintaining the functionality and shape of the milling teeth.
  • Rust Resistance: Rust on the sleeve and steel body can cause materials to get stuck in the rotation space, leading to operational inefficiencies. Ensuring rust resistance helps maintain smooth operation and prolongs the life of the teeth.

IV. Challenges for Milling Teeth to Address Each Indicator
