ABOUT THE MOTION OF THE VIBROLIQUEFIED SEPARATED LAYER OF GRAIN ON THE FLAT SIEVE OF FINITE WIDTH

abstract 1231609036 issue 123 pp. 536 – 544 30.11.2016 ru 216
The aim of the research is analytical determination of the middle speed of the corn seeds on the flat vibrating sieve of finite width. The object of the study is the process of sorting of seeds of corn on the flat vibrating sieve. The mathematical modeling of the motion of the separated layer of the cereal mixture on the sieve is conditioned by the necessity of intensification of division of grain-growing materials on a flat sieve. Despite the significant progress in the development of mathematical models of the motion of a mixture on vibrated sieve, their further refinement remains an actual task. In particular, in calculation practice, theory in which the width of the flat sieve is considered infinite is used, i.e. the impact on the process of the moving frame of the sieve bed is not taken into account. In connection with absence of estimations of the error brought in by this assumption, the necessity to develop a theory of the movement of the mixture on a sieve of the finite width appeared. For the analysis, the following assumptions were accepted: first, the corn seeds were considered as balls of different diameter, second – the layer of grain on a sieve was considered as heterogeneous viscid liquid. Based on undertaken study it is set that most rational for the achievement of the put aim is application of method of Bubnov-Galerkin. As a result of undertaken research analytical dependences are received for the calculation of flowrate of grain mixture on the vibrational sieve of the final width taking into account separation of the mixture into factions

CONSTRUCTION OF THE GEOMETRY OF THE DISK OF THE SHREDDER LONG-STEMMED FEED, BASED ON THE SECOND TURN OF THE ARCHIMEDES SPIRAL

abstract 1541910026 issue 154 pp. 269 – 277 30.12.2019 ru 12
The aim of the study is to determine the parameters of the Archimedes spiral to construct the geometry of the disc of the shredder of long-stemmed feeds. The article describes the sequence of constructing the curved portion of the geometry of the disc of the shredder of long-stemmed feeds, based on Archimedes spiral. Criteria for building the disk on the second and subsequent turns of the spiral of Archimedes and obtained the dependence of disk diameter from the size of its protrusions. The conditions of Archimedes spiral construction depending on the number of disk protrusions are determined
