High-Efficiency Industrial Plant Construction Site with Scarifier Tungsten Carbide Cutters

Scarifier Project Location: Industrial Plant Construction Site, Guangdong Province, China

Equipment Used: Concrete Milling Machine (Model: XM-200) with Tungsten Carbide Cutters

Application Scenario:
The project involved the removal of a 200mm thick, heavily reinforced concrete pavement in a manufacturing plant to facilitate utility pipeline installation. The existing concrete had a compressive strength of 40MPa, posing significant challenges for conventional milling tools.

Key Challenges:

• Exceptional Wear Resistance: Reduced tooth replacement frequency by 60% compared to standard steel teeth.
• High Milling Efficiency: Achieved a milling rate of 35–40 m²/hour (depth: 50mm/pass) despite the hard substrate.
• Rebar Tolerance: Carbide teeth maintained sharpness even after accidental rebar contact, avoiding downtime for replacements.

​Results:

• Time Savings: Completed 1,200 m² of milling within 30 hours (25% ahead of schedule).
• Cost Reduction: Only 2 sets of teeth were used (vs. 5+ sets with conventional tools), saving ~¥8,000 in consumables.
• Surface Quality: Uniform texture (3–5mm roughness) allowed direct installation of new utilities without secondary leveling.
• Client Feedback:

"The carbide teeth outperformed our expectations. Zero unplanned stops for tool changes—just non-stop milling."
