Surface Miner Bests Dozer in Trial

Surface Miner Bests Dozer in Trial

Wirtgen reported a 220 SMi 3.8 surface miner outperformed a crawler dozer solution in a field trial at a chalk quarry in Chouvrot, France. In the trial, which included wet conditions, the goal was to mine 500 m3 per hour. Among other parameters, cutting performance, turning time and fuel consumption were tracked and compared. The surface miner features adjustable longitudinal and cross slopes for water drainage. It offers a cutting depths of up to 350 mm and a uniaxial compressive strength of up to 35 MPa. For the trial, it first used a 3.8-m-wide cutting drum, designed specifically for soft-rock mining, and then switched to a 2.2-m-wide drum.,” the company reported.
