The paper presents the results of research of dependence of indicators of fire danger of wood-fiber plates with reduced fire risk from technological and design parameters of the milling process. The work is aimed at obtaining hardboard wet process production with indicators of fire danger, reduced to the level of flame-resistant according to GOST 12.1.044-89 «Fire and explosion hazards of substances and materials. Nomenclature of indices and methods of their determination». For the task solution in the work there were used methods of mathematical planning with the aim of obtaining the mathematical description of grinding process of wood-fiber mass during the manufacture of hardboard panels with a reduced fire hazard. Construction of mathematical models of object is an important part of scientific research. Developed mathematical model of the object are a good research tool. The equations describing the studied processes of preparation of wood materials, in our view, allow for obtaining high-quality wood mass depending on the set modes of the milling process; under certain values of the constructive and technological parameters of the refining installations and by changing the values of the mass fraction of expanded vermiculite in wood-fiber composition, to lower the parameters and indicators of fire danger plates made of it.
