Bulk Bag Discharger Controls Discharge Of Poorly Flowing Materials
The Universal Type 2 Bulk Bag Discharger (BBD) controls flow by means of a highly accurate, highly repeatable integral flexible screw conveyor. Directly coupled to the base of the bulk bag discharger, the flexible screw conveyor meters the flow of big bag contents to the user's process vessel. The unit is well-suited for all big bag types, with sizes up to six feet high and up to two tons in weight. A dust control connection facilitates connection to the factory dust extraction system or to a local dust collector integral with the BBD. The bag is lifted by forklift truck on to the bulk bag support frame. Spring-loaded arms gradually raise and tension the bag during emptying to ensure complete discharge of the product. The arms also prevent the bag spout or liner from sagging or fouling the take off conveyor. Bags sit on a substantial support dish through which the neck of the bag passes in to the dust cabinet below. A membrane in the dish ensures that there is a seal between the bottom of the bag and the dust cabinet.
