Bulk Bag Discharger

CHARLOTTE, NORTH CAROLINA - Spiroflow Systems, Inc. offers an innovative “Hoist Design” Bulk Bag Discharger for unloading bulk bags without the need of a forklift truck.

Spiroflow’s Type 6 Bulk Bag Discharger (BBD) is used for unloading powder or granular product material into various processing equipment including mixers, sifters, mills, etc. a well as into packing equipment. Transfer from the BBD to process or packing can be direct or via one or more of the range of conveyors manufactured by Spiroflow. Their range comprises flexible screw, vacuum, pneumatic, and aero-mechanical conveyors.

Each Type 6 BBD is tailored to suit individual customer specifications and is available in carbon steel and 304 stainless steel options. The Type 6 unit is designed to allow one operator to control a standard 1-ton hoist which positions the bulk bag into the discharger. The hoist runs along a fully load tested integral “I” lifting beam.

The Discharger boasts innovative bag tensioning supports which compensate for the capacity/weight of the bag and stretches it to ensure total discharge. Pneumatic side and/or base massage paddles are available, when appropriate, to promote the flow of sticky, cohesive or otherwise difficult products.

Each discharger has dust tight material collection hopper with integral locking access door and viewing port. The door is amply sized to enable the operator to untie/re-tie the bag spout and liner.

MULTIPLE TRANSFER OPTIONS
Spiroflow Systems offers various transfer solutions including Flexible Screw and Aero Mechanical Conveyors as well as Pneumatic and Vacuum Conveyor Systems that offer solutions for both metered feed or mass flow conveying requirements. In some cases, customers may require multiple transfer solutions for their Bulk Bag Discharging. Spiroflow offers mobile conveyors that connect to the BBD. For example, a recent project required two feed options; one to deliver product at a metered feed rate and the other to deliver product en masse. Spiroflow’s mobile Flexible Screw Conveyor and Vacuum Conveyor were used to meet the requirement. The conveyors, which consisted of a mobile base, inlet hopper and conveyor, could quickly and easily be connected to the Type 6 BBD that would discharge a variety of products to a packaging machine that has two feed points. (See Photo). Only one feed point can be in operation at any time. Either way, product fed to the packing head has to have a consistent flowability and has to be de-aerated within specified tolerances.

OPTIONAL EQUIPMENT
Other optional equipment for the Type 6 BBD includes loss-in-weight load cells, enabling batch weights of product to be discharged from the bulk bag as required. Bag neck pinch bars can be included to enable flow from the bag can be controlled with the access doors closed – an essential option to protect the operator and the environment from dusty of hazardous materials. Pinch bars are ideal where part used bags need to be removed so that bags containing other ingredients can be installed into the discharger.
