  • Patent number: 6089283
    Abstract: A method of filling containers with bulk material wherein a bag is filled, weighed and densified at the same time. The bag is supported on a releasable hanger. The bag is constantly weighed, and a predetermined quantity of material is placed in the bag. The bag is raised and lowered and vibrated to settle, or densify, the material while the material is being admitted to the bag. The bag may be vibrated while being filled by counter-rotating vibrators. The material is weighed and the net weight is determined. The method of the present invention can be used for filling drums, boxes and other containers, as well as bags. Specific designed power operated hooks are used to support the bag. The containers are supported on a platform. Drums as well as bags can be filled without any change in the machine requiring tools.
