In the past two articles, we discussed the history and classification of FIBCs bags. As the heavy packing method, it is not easy to fill and discharge them during the use, even dangerous as you know,
1.What filling and discharging design options are available for FIBCs?
The filling and discharging design options selected are going to be dictated by a number of factors including:
• Filling Method (i.e conveyer, gravity, bulk bag filler)
• Where FIBC will be filled (clearance, electrostatic concerns, flammable products, etc.)
• The FIBC filling equipment desired or currently used
• Desired fill or packaging rate
• Sizing restrictions / constraints
• Fill spout dimensions required
• Controlled discharge desired
• Discharge method (i.e. gravity, screw, conveyor, bottom cut, full dump)
• Where FIBC will be discharged (clearance, manual, electrostatic concerns, flammable products, etc.)
• Desired discharge rate
• Discharge spout dimensions required
• Handling preference: Existing hoist and trolly frame fork loaded frame
2.How do I safely fill FIBC?
During the filling process FIBC should be hanging from the lifting device in a way that their bottom either touches or hangs closely above the ground or pallet. In order to ensure stability under load, the filling height of the FIBC should be between 0.5 and 2 times the shortest horizontal dimension of the FIBC, typically.
• the diameter for FIBC with a round base,
• the length of the shorter side for FIBC with a rectangular base.
3.How do I securely discharge FIBC?
In order to discharge a single-trip FIBC, its bottom should be opened using a cutting device equipped with a suitably long grip. If the FIBC has a discharge spout, this spout should be opened only when the FIBC is hanging over a safety support. This support prevents injury to persons in case the lifting device fails. Persons should under no circumstances stand or hold body parts under any lifted or non-secured FIBC.
