Abstract: A method and apparatus are provided for dispensing material from a bulk bag wherein the bag is supported from below by a cradle having a central opening through which material from the bag may pass. An overhead support is employed to prevent the bag from collapsing downwardly as the bag empties. The apparatus includes a discharge assembly positioned beneath the opening and extending generally downwardly therefrom for receiving material from the bag and directing the material to a desired location.

Abstract: Partially purified salt containing less than about 00.4 weight percent insolubles is further purified to reduce the insolubles until the milk pad rating is 3 or better for certain industrial uses and 1 for human consumption. The entry salt is washed in clarified brine to dislodge insoluble impurities adhered to the salt surfaces. The washed salt is then scrubbed with fresh water sprays to displace the wash brine from salt surfaces. The washed salt is drained and then dried in a kiln where flowing air blows away some impurities. The dried salt is passed through a magnetic separator, doubly sifted to remove both large and small impurities, and, where food grade salt is required, passed through a color sorter that removes relatively dark impurities.
