Rock Grinders For Tough Applications

  • 1. Trench / Pipeline Construction
    • Rock grinders produce smooth trench wall with straight parallel sides. Threnches can be excavated accuratley to the size required. The grinded materials can be re-used as back fill without additional crushing
  • 2. Trunneling
    • Rock grinders are commonly used for scaling operation in tunnel construction after drilling and blasting. Profiling work is also common work in tunnel construction after blasting and before installation of ground support such as screen and bolts or shotcreating
  • 3. Foundation Work
    • Rock grinders ensure safe cut under existing infrastructure such as services pipes and ventilation. Deep excavation for underground work, site preparation and leveling work can be done by this tool.
  • 4. Demolition / Building renovation with low vibration
    • Rock grinders are used in urban demolition site where extremally low noise and vibration are required. They can be also used for rehabilitation of sensitive concrete structure such as foundations and bridges
  • 5. Quarrying and Excavation
    • Rock grinders are an ideal tool for gypsum and limestone mining, excavation soil, soft rock, asphalt and concrete. Its combination of cutting force and precision ensure a high performance and productivity in those job sites.
