Energy-efficient system of pneumatic transportation bulk materials

The technology of pneumatic transportation of grain and products of its grinding determined mathematical models of pneumatic transportation of mixture ways and technical means of regulating the air velocity in pneumatic product pipelines direction of realization energy efficient operating modes of pneumatic transportation installation are considered. The technological scheme of flour production and calculation of quantities-qualitative balance of the process of grinding the grain is given. Made researches of static regimes of the process of transportation of the grain and products of its grinding defined the ways of reducing of the energy efficient on the pneumatic transportation. Developed mathematical model of the dynamics process of the pneumatic transportation and carried out the study of dynamics of pneumatic transportation installations with using the package of application programs Мatlab. Parameters operating modes and developed regulated electric drive of pneumatic transportation installations are justified.
