Abstract
Experimental data on the energetic, electrotechnical, temporal characteristics and mechanism of the process of sewers 56×3 and 76×3 mm refinement from solid sediments with thickness 4-8 mm were received. Granulometrical composition of destroyed sediments was examined. Its peculiarities, which influence on the selection of regimes and technological methods of tubes refinement were exposed with the help of sequential visual schematized pictures of the destruction process.
