Surface mining with surface miner drums and cutting bits lets you go beyond scratching the surface with more control and less cost. You mine only the area of the mineral deposit (blasting requires a wider range for the debris field). There's no drilling or blasting, storing explosives, or downtime between these operations.
The mining machine is made up of discrete units which include a machine body and machine housings joined to opposite sides of the machine body. The winch is either coupled through a drive train with a feed drive motor or coupled to the drive motor for cutter drums. The machine housings each support a pivot shaft coupled by an arm to a drum cutter.
50 Hz) to provide a significant increase in horsepower to the cutting system. Reduced thermal losses in the cutter motors and trailing cable increase the available continuous cutting time almost indefinitely, leading to improved production levels. With a high-voltage cutting system, the 12CM27 is typically operated well within its maximum operating
