Department of aerogasdynamics

Head of department – Corresponding Member of the National Academy of Sciences of Ukraine, D.Sc., Professor V. I. Tymoshenko

Technology essence

Carrying air increased pressure (density) use for granular materials pneumatic transportation

1 – compressor
2 – pipeline
3 – loader
4 – granular material feeder
5 – discharging and separating devices
6 – air return

Features and advantages

  • hydraulic resistance and energy expenditure
  • particle motion speed at the pipeline end site
  • abrasion wear of the pipelines and running system units
  • grinding of the transported materials
  • ecological environmental load

Comparison characteristic of pneumatic transport types

Stand specification

Operating pressurefrom 0.1 to 3.3 MPa
Required power30 kW
Stand coolingwater
Total length of the linear partup to 70 m
Flow velocityup to 45 mps
Particle size of a solid phaseup to 10 mm
Volume of loaded materialup to 30 l
Volume concentration of a solid phaseup to 15%

The stand allows to operate according to open, half-closed or closed circuits with air and granulated material. On pressure level it is better then any Ukrainian and foreign equipment.
