Granular Material Pneumatic Transportation Under Increased Pressure of Carrier Gas

Section: Scientific Basis of Innovation Activity
Language: Russian
Abstract: Based on the calculated estimates and results of experimental studies on the laboratory bench with pneumatic pressure of the carrier gas up to 3.3 MPa it is shown that the use of carrying gas at increased pressure for granular material pneumatic transportation allows to reduce transportation energy expenditure and the velocity step of carrier gas at the beginning and at the end of pneumatic transport line under given pneumatic line capacity. Comparative data for designed parameters of the pneumatic transport system for wheat movement at a bakery plant from the grain elevator to the miller in the traditional way and with the use of increased pressure is given.
Key words: pneumatic transportation, increased pressure, granular material, experiment, hydraulic resistance, compressor, energy expenditure, transportation distance.
