Cutter heads from Rock Grinders(Drum cutters) are designed to provide the optimum cutting power at the recommended cutting speeds. They guarantee a smooth cutting action while providing each pick with the maximum cutting power to penetrate the rock.
High torque hydraulic motors drive extremely large spur gears to turn the cutter drums. The gear wheels are so robust the drum cutters can be used in the most difficult conditions without risk of failure.
