Surface mining | Technology | Wirtgen

While the surface miner moves forward, a special cutting drum rotates against the direction of travel, cuts material layer by layer from the rock formations, and crushes it in the process. The primary conveyor receives the rock from the drum housing and transports it to the end of the machine, where it is transferred to the height-adjustable discharge conveyor that features wide swing angles.
