Description
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

MATHEMATICAL MODELING OF THE WORKING PROCESS OF LEVER BREAKER
DescriptionThe 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

01.00.00 Physical-mathematical sciences
DescriptionArticle is devoted to the numerical analysis of regional problems for system of the equations of Nernst-Plank-Puasson (NPP), to application of these regional problems to modeling and studying of mass transfer in the channel desalting of electro dialysis device. Various mathematical models of the transfer of ions in potential static mode in the form of system of the quasilinear equations with private derivatives are offered. The basic rules of occurrence and development of a spatial charge in the channel desalting of electro dialysis device are revealed
