Apparatus for filling bags and simultaneously providing complete, controlled collection and discharge of dust generated from particulate material with which the bags are filled. The discharge end of a spout positioned under a hopper is formed by a pair of closure members movable between open and closed positions on which the mouth of a bag may be clamped by clamping devices movable into clamping engagement with the top, opposed faces of the bag against the outside of the spout closure members. Dust collectors are provided on the spout and are so located as to be in fluid flow communication with the interior of the top of a bag hung on the spout discharge end. Suitable conduits connect the dust collectors with a vacuum source to remove all dust generated when particulate material is discharged from the hopper, through the spout, into a bag. A flexible liner is also hung inside the spout to contain the prevent the escape of dust during bag filling operations.
