Abstract
A silo for bulk materials has a rigid base and a fluidizing means which comprises an air-pervious mesh floor arranged above the rigid base, a support surface means holding the said floor in spaced relation relatively to the rigid base and at least one compressed air supply duct opening into the intermediate space between the rigid base and the mesh floor, the support surface means being formed by a wire gauze placed on the rigid base. The wire mesh may be annular and may be in sector-shape portions with a radially extending packing or seal arranged between each of the separate sectors and a compressed air supply duct associated with each sector. A helical wire mesh is particularly described and illustrated, with tube sections arranged as seals on the terminal wire helices.
