Abstract

Apparatus for controlling discharge from a silo, comprising a device mounted internally of a discharge opening for flowable material and forming with that opening a flow path for material through the opening. A bellows actuator associated with the device moves the device relative to the discharge opening to close the opening or to open it to a desired extent. A vibrator carried by the device vibrates the device to assist flow of material through the discharge opening when it is open.
