Abstract
A grid-shaped grate for carrying randomly poured particles or filler bodies in mass transfer columns. Each grate comprises of a plurality of grid walls defining openings for receiving the particles or filler bodies, the openings being smaller in size than the particles or filler bodies. The grate is provided at each intersection of the grid walls with spacers which are equally spaced one from another at a distance which is approximately equal to the width of each grid opening. The height of each spacer is approximately equal in size to at least one half of a particle or filler body size, so as to prevent the particles or filler bodies from closing the grid openings.
