Abstract
A silo for pulverulent and other loose materials has outer silo walls, a lower circular silo base, a conical cover in the center of the lower circular silo base, and an upper intermediate circular silo base arranged between the outer silo wall and the conical cover and above the lower circular silo base. An annular space is formed between the upper and lower silo bases to act as a collecting chamber for receiving loosened material from the silo upper storage area and collecting and feeding the lossened material to discharge outlets in the lower silo base. The loose material passes via radially directed slots formed in the intermediate silo base from the upper silo area into the collecting chamber. The slots are adustable and pneumatic mechanisms are located adjacent the slots for fluidizing and ensuring proper mass flow of the materials from the upper silo area into the collecting chamber. Outlets are located in the lower silo base for discharge of loosened material held in the outlet chamber.
