Wirtgen says the new cutting drum enables cost-efficient extraction of hard rocks
Wirtgen Group will showcase a new cutting drum for surface miners at MINExpo 2024, which the company says enables cost-efficient extraction of hard rocks with uniaxial compressive strengths of over 100 MPa.
The Cross-Application Miner 260 SX(i) speeds up infrastructure projects by eliminating drilling and blasting, facilitating stable embankment construction, in-situ grading, and material recycling.
The new cutting drum features HT14 toolholders and a redesigned cutting geometry, enhancing the extraction of materials like limestone, gypsum, and anhydrite, according to Wirtgen Group.
The company says its Wirtgen 280 SM(i) Surface Miner successfully used the new cutting drum in a limestone quarry in Louisville, Nebraska, eliminating the need for drilling and blasting.
Visitors to MINExpo 2024 can engage with Wirtgen Group experts on deployment, project assessment, machine recommendations, cost estimation, and financing solutions.
The MINExpo 2024 will take place from September 24 to 26 in the Las Vegas Convention Center.
