- Abstract
- The study compared the effect of chipper type on productivity, power demand, fuel consumption
and product quality. Tests were conducted on two commercial chipper models, a disc and a drum
chipper. Both chippers had the same diameter capacity, were applied to the same tractor and fed
with the same feedstock types. Fifteen replications were conducted per machine and for each of
four different feedstock types, reaching a total of 120 tests. 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. The drum
chipper produced smaller chips, with a higher incidence of fines. Feedstock type had a strong
effect on productivity, energy efficiency and product quality. The effect of feedstock type was
mainly related to piece size, and may be stronger than the effect of chipper type. Further studies
should determine the effect of blade wear on the relative performance of the two chipper types. (literal)
