This Double Drum Cutter with a direct drive motor system, a unique patented system that allows for the differential distribution of power to two rotary cutting heads,
Cutter heads from Rock Grinders 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.
The productivity of a drum cutter depends to a large extent on the uniaxial compressive strength of the material to be cut. The deeper the pick can be forced into the rock, the more material it can break out from it which in turn, increases productivity.
The oil flow and pressure that the excavator is able to provide to the drum cutter combined with excavator weight and stability are also critical factors influencing productivity.
