    A commercial drum and disc chipper with the same diameter capacity were compared. They were the Pezzolato PTH 300 G drum chipper and the Pezzolato H880/250 disc chipper, and were both new chippers powered by the same tractor (a 100 kW Case New Holland 140). The chippers were fed the same feedstock types and both used a two-blade configuration.

  • Comparing the efficiency of drum and disc chippers -

    The disc chipper had a higher energy efficiency and used 19% less fuel per unit product, possibly due to its simpler design, integrating comminuting and discharge system in one synergic device. In contrast, the drum chipper was 8% more productive, since it cut with the same energy all along the length of its knives.

    Drum chippers are more productive than disc chippers, with a difference of about 10%. Drum chippers, on the other hand, are less energy-efficient and consume about 20% more fuel than disc chippers per cubic meter of wood chips produced. The high energy efficiency of disc chippers may be related to their simpler design (Liss 1987).
