At MINExpo 2024, from Sept. 24-26, at the Las Vegas Convention Center, the highlights from Wirtgen Group will include insights into its cutting technology solutions. The focal point on Booth 6815 at the show will be a new cutting drum that now also enables the cost-efficient extraction of resources with uniaxial compressive strengths of over 100 MPa UCS (14,500 psi).
Limestone, Gypsum, Anhydrite and Other Hard Rocks and Minerals – The new cutting drum is equipped with HT14 toolholders and features a redesigned cutting geometry. The field-proven and established central-drum concept, which ensures optimum utilization of the machine weight, and the direct belt drive that guarantees the transfer of high usable power to the cutting drum, also contribute to the ability of Surface Miners to profitably extract even very hard rocks and minerals with uniaxial compressive strengths of 100 MPa UCS (14,500 psi) and more – for instance limestone, gypsum or anhydrite.
The Wirtgen 280 SM(i) with the New Cutting Drum in Action – The new cutting drum celebrated its premiere in practice on a limestone quarrying job carried out by a Surface Miner 280 SM(i) in Louisville, Neb. In addition to the extraction of very hard limestone at the quarry, the elimination of the need for drilling and blasting made it possible to extract previously unexploitable limestone deposits and extend the working life of the quarry and all downstream production systems by several decades. For the quarry operator, surface mining is a cost-effective extraction solution that also contributes to safeguarding jobs, increases safety in the quarry, and enables responsible management of resources.
Faster Infrastructure Projects – Wirtgen expanded its portfolio of products and applications with the Cross-Application Miner 260 SX(i) two years ago. The Cross Application Miner speeds up construction times by eliminating the need for drilling and blasting, with the construction of stable embankments, in-situ grading of railroad tracks, and the recycling of the extracted material in-place for use in further construction.
Wirtgen Group Services: Expertise and Best Practices Are Essential – At MINExpo 2024, trade and industry visitors to the show will also be able to talk with surface mining experts from the Wirtgen Group about all other aspects of the solution – for example deployment and project assessment, recommended machines and equipment, related cost and performance estimation, and financing solutions.
