摘要

The invention refers to a device on a pocket (1) for crushed or powdered materials. The pocket has a downward narrowing part that leads into an outlet (4), in which a chute (6) is housed for swinging between a downward tipped position for releasing materials and an upward tipped position in order to prevent the release of crushed materials. According to the invention, there is a separate hatch (20) set up between the outlet and the chute in order to prevent the release of powdered materials. This hatch is movable between tightly sealed positions over the outlet opening to a position that uncovers the outlet opening.IMAGE
