“…Numerous theoretical and experimental studies show that such factors as the gap between the rotor and stator cutters and the angle of the stator cutter contact with the raw material have the greatest effect on the grinding process under consideration. Such factors as the temperature of the wood-fibre pulp, the ratio of coniferous and deciduous species and the rotor rotation frequency have less effect (Chistova 2010;Zyryanov 2012;Morozov 2016;Vititnev 2019).…”

This paper presents the results of an assessment of the morphological characteristics of semi-finished wood-fibre products obtained from waste fibreboard using a rotary cutting machine by dry grinding. The work has established the influence of machine design parameters, such as the gap between the rotor and stator cutters and the angle of the stator cutter contact with the raw materials, on the mass fraction of small fibres and fines in wood-fibre pulp. These parameters determine the main structural characteristics of boards and ensure fibre bonding. The paper describes the collision of single secondary wood fibres that leads to the development of primary cracks, contributing to external and internal fibrillation in the absence of high temperatures and pressure without using chemical additives or water and steam.
