Spiroflow Systems Offers Universal Bulk Bag Discharger Designed to Control Discharge of Poor Flow Materials by Volume
CHARLOTTE, NORTH CAROLINA---Spiroflow Systems, Inc. offers a Bulk Bag Discharger providing controllable discharge by volume of poor flowing materials without wastage or spillage for increased productivity and a cleaner work environment.
The 'Spiroflow' Universal Type 2 Bulk Bag Discharger (BBD) controls the 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 customer's process vessel.
The Spiroflow Type 2 Bulk Bag Discharger 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.
An operator unties the bag through an access door in the dust cabinet, which is above the discharge chute leading to the conveyor below. Once the bag is untied and the cabinet door is closed, discharge takes place dust-free.
An optional pneumatically operated massage system is available to assure the consistent flow of difficult products or products that have become compacted during storage or transportation. There are 3 types of massages available: side, base and corner. These can be used individually or together. Trials determine the optimum combination. Massager positions are adjustable in any case - should the nature of the product change.
Spiroflow's powder handling expertise ensures a transfer method from BBD to process best suited to each customer's product, whether it is by way of the integral flexible screw conveyor mentioned previously or an aeromechanical conveyor, rigid screw conveyor, pneumatically or by vacuum.
OPTIONAL EQUIPMENT
Other options available for the 'Spiroflow' Universal Model T2 Bulk Bag Discharger include bag spout closure bars, a liner remover, a mobile frame and an integral bag dumping hatch.
Bag spout closure bars can be used to control the flow of material but they are an essential requirement for dusty or hazardous materials. They pinch the neck of the bag above the point where the outlet spout is tied. Once the spout is untied, the pinch bars can be opened to allow discharge to begin. Flow, in this case, begins only after the access door in the dust cabinet has been closed - offering greater dust containment.
The mobile frame design is a versatile option for processors that require bag discharging at various locations.
Integral sack dumping stations are a neat option where minor additives need to be introduced in to the process or as a fall back position should the supply of material in bulk bags be temporarily disrupted and supplies in bags have to be used instead.
