“…Hence, the result obtained in the current study confirms a primary effect of wood characteristics on particle size distribution. The fact that neither study found the same effect for dry branches points at the significant benefit obtained by letting branch material dry before comminution, as already found by Suadicani and Gamborg (1999).…”

A study was conducted to determine the effect of some wood characteristics such as species, moisture content and tree part on the performance and product quality offered by a mobile industrial chipper, of the type commonly used for roadside chipping. Two main species, two tree parts and two moisture content levels were combined in a factorial design yielding 8 treatments, each replicated 5 or 6 times. A flow meter was installed on the chipper engine, and all chips produced were weighed and sampled for moisture content and particle size distribution. The results indicated that some wood characteristics such as species and moisture content have a secondary effect on chipper productivity and fuel consumption, which are primarily controlled by piece size. In particular, fuel consumption per unit dry mass seem to be rather constant and in the range of 3.2 l per oven dry ton. Moisture content and tree part may have a significant effect on the particle size distribution of chips. Of course, these results were only verified for the species used in the test and for industrial chippers, and may change if substantially different species or machines are used.

“…Different wood moisture content was likely to affect the efficiency of the work tools, through its effect on wood density and friction, independent of chipper type (drum or disc). Suadicani and Gamborg [24] found a similar effect when using the same chipping principle on freshly felled and stored Norway Spruce (Picea abies L. Karst). In their experiment, they obtained a different particle-size distribution for the two different materials.…”

“…The storage of whole trees over the summer has been shown to reduce their contents of Ca, Mg, K, and N significantly (Suadicani & Gamborg 1999). Storing and drying the fractions that are richest in twigs would dramatically reduce the adhesion of the needles, increasing the efficiency of removal methods such as screening.…”

This review provides a survey of the literature on methods for comminuting and sorting woody biomass. The reported methods were classified according to their basic operating principles: methods of comminution were separated based on whether they use sharp, semi-sharp or blunt tools; methods of discrimination were classified according to the parameters they use. The identified methods of comminution differ significantly in terms of productivity and energy use. The differences between individual biocomponents with respect to the parameters used for discrimination (such as solid density, or particle size and shape) are often rather small and species dependent, which makes it difficult to efficiently sort woody biomass from mixed species. Other parameters (e.g. optical and near-infrared properties) can be used as inputs for active sorting on larger scales. Several methods for tree processing and chip sorting that were originally developed for pulp-chip production now see little use because they are not considered cost-effective. However, the economic importance of fuel products has increased substantially in recent years. Fuel can be produced using material with a higher bark content than is tolerated in pulp chips, so it may be worth re-evaluating some of the methods that were previously discarded. Examples include tree-processing machines such as drums and cradles for partial foliage removal, processes such as delimbing and debarking (which facilitate downstream sorting of the comminuted material), and screens and wind classifiers for processes such as separating fines (often ash-rich) from comminuted material. The available data on the performance, required investment, and operating costs for these methods are incomplete and often not comparable. This issue must be addressed to facilitate the development of optimized fuel supply chains.
