This paper presents the results of granulometric analyses of sawdust of unmodified and thermally- modified ash wood (Fraxinus exelsior L.) sawed on a narrow-kerf sash gang saw. The sawdust of dry thermally-modified ash produced in the sawing process on a frame sawing machine PRW15-M at a feed speed in the range of 0.36-1.67 m·min-1 has chip granularity ranging from 33.5 μm to 9.9 mm; whereas unmodified ash wood sawdust consists of chips in a granularity range from 35.6 μm to 13.8 mm. It was observed that thermally-modified ash sawdust is finer, with a distinctly larger share of the fraction in the granularity range a = 125-500 μm and a slightly increased share of the fraction in the range a = 32-125 μm. Changes in mechanical characteristics of modified wood were also observed in the technological usefulness of a part of dry sawdust chip in the granularity range a = 250 μm-2.4 mm. While the homogenous share of chips in sawdust produced in the process of sawing of dry ash wood was HSCha = 81-84 %, the demonstrated homogenous share of chips in ash sawdust formed in the process of sawing of dry thermally-modified wood was lower by 4-6 %.
