FIELD: transportation.
SUBSTANCE: in compliance with this invention, the device contains fabric layers of fluidising elements representing two or more sintered and rolled fabric layers of metallic wire. The wire of, at least, the top outer layer is skewed or deflected to form deviating flowing channels (34). The innermost metallic wire fabric layer features the cell smallest width and smallest wire thickness, while the top outer layer features the widest cell and thickest wire.
EFFECT: loose material accelerated motion lower costs.
