Abstract

During loading of the hopper it is connected internally with a vacuum source, and a swing shutter is pulled against the outlet in the shut position. Means are provided for determining when the shutter is in the open or shut position. Typically these can be connected electrically to a programme control unit, which arrests the command for pneumatic loading of the bulk material into the hopper when the shutter is open. A seal can be provided at the hopper mouth acting against the shutter due to the pressure difference between the inside of the hopper and atmosphere. The shutter can swing on an arm on the hopper, returning to the closed position under its own weight.
