In this article, the direction of an improvement of the working process of roller-die pellet mills with a ring dies by butt restriction of wedge-shaped space by addi-tional contact surfaces is proved. The mathematical model of the process of pressure granulation (pelleting, extrusion agglomeration) of plant raw materials in the conditions of the closed wedge-shaped space between a die and each of press rollers is presented. On the ba-sis of the analysis of the mathematical model possi-bility of significant increase of capacity and decrease in energy intensity of pellet mills having additional contact surfaces in the form of restrictive rings is shown
The dependences of the distribution of stump roots, allowing to model stump parameters to assess the difficulties of stumping are given, in requirements justification for stumping equipment. Based on the analysis of lever breaker working process, the differential equation of lever motion is got, which connects the moments acting on it and breaker performance modes and allows to set the parameters and modes of lever breaker in stumping of various sizes and species of wood
The article shows the results of experiments to assess the effectiveness of multipoint and polygamous, which form the basis of the proposed mixed-evolutionary method, in comparison with known genetic methods
Rheological model for wood mechanical behaviour, viewed as a medium with dual porosity, is considered. Mathematical modelling of compression process of a wooden sample in a special mould is done at stable temperature conditions with the help of numerical methods. It is shown, in particular, that the durability level of essentially depends on the rheological characteristics of the structural skeleton and the wooden substance, as well as on reallocating of fields of moisture and porosity
