The surface miner is a mobile milling machine with a mechanically driven cutting drum. On Wirtgen machinery the drum is located between two sets of individually height adjustable crawler tracks, and a two- stage conveyor system used to directly load trucks.
Wirtgen surface miners cut, crush and load the material in one single pass. This process eliminates the need for drilling, blasting, loading and primary crushing. This means that one machine completes the job of many different pieces of equipment. The mining process thus becomes straightforward and economically efficient.
