Abstract
An upright storage silo for fluid materials, such as comminuted, powdered and granulated livestock feed, flour, grain, spices, sugar, cement, fertilizer and similar, has a mixing chamber centrally located within the silo; a discharge chamber within the silo in communication with the mixing chamber, and defining an area separate from the silo interior; a plurality of aeration orifices within the floor of the silo; a lifting tank in conduit connection with the mixing chamber and discharge chamber; a shut-off mechanism, and a dosage mechanism for conveying the material from the silo. Flow control apparatus of the pressure of aeration is employed for lifting, pulverizing and discharge of the material by utilizing the increased discharge pressure of the pulverized material for the lifting thereof. The material rises under the increased pressure in communication with the silo discharge aperture and thereafter the pressure is relaxed.
