Large volume silo for bulk material, particularly raw cement powder

摘要

A large volume silo has in the center of the base a conical dome which, together with the cylindrical outer silo wall, defines an annular base. Open air conveyor chutes pass from the base area through discharge openings to flow regulators in the inner area beneath the conical dome. Closed air conveyor chutes follow on from the flow regulators and lead to a common storage tank in the inner area beneath the conical dome. The open air conveyor chutes can be separated from the bulk material in the silo area by cover slides moveable from the inner area of the conical dome over the open air conveyor chute. This repairs to the conveyor chutes without interrupting silo operation. The cover slides are operated from the interior of the conical dome.
