How to properly unclog a big bag (FIBC) when unloading
PP Big bag (FIBC) with a bottom spout is ideal applications due to its flexibility and easy-to-control material discharge. However, due to this design, the bottomioutlet of the bag may be easily clogging.
This clogging (usually called bridging) occurs because the material adheres to itself and accumulates around the outlet of the bag during the unloading process. Bridging is especially common in applications involving materials with high moisture content, such as fresh organic products and agricultural products.
Bridging will delay the discharge of materials, which greatly affects your operational efficiency. Bridging may also bring safety hazards to workers, so it is important to understand the best way to unclog the big bags. Let us explore the safest way to do accordingly.
Sueestions for Unclogging a Filled big bag (FIBC bags)
If you try to unclog a bulk big bag with bottom spout, Please do not stand under the bag. Doing so can be very dangerous and may cause serious injury.
Fortunately, there are many possible ways to unclog the bottom spout bulk bags without harming workers, including:
Use a broom handle or other type of extension rod to push down the bottom of the nozzle and try to release the material, keeping away from the unloading big bag as far as possible.
Massage the area around the spout with your hand or extension rod to try to loosen the material. Pay close attention to the discharge spout and avoid getting under the bags.
While standing above the bag, use the broom handle or extension rod to push the material through the nozzle. When trying this method, make sure to maintain a stable foothold and keep other workers away from the bottom of the bag.
Cutting the bag at the bottom of the nozzle. This method can only be used as a last choice, because it makes the bag unusable. When trying this method, please be careful with the blade and minimize cutting to avoid uncontrolled discharge of materials. If possible, use blades that can be used at long distances to minimize the risk to workers.
No matter which method you choose to try to clear a clogged outlet, GuanSong FIBC packaging bags encourages you to consider all hazards and implement all available safety procedures.
Prevention is the safest way
Although bridging may not be completely prevented, especially when handling materials with high moisture content, there are steps you can take to limit the possibility of nozzle clogging.
To prevent bridging, please consider: Use an extra-large discharge spout bottom bag: the latest innovation on the market, the diameter of the extra-large discharge spout bottom FIBC is 28 inches. The faster discharge rate of the larger nozzle and the larger opening can prevent material bridging, thereby improving reliability and safety for users.
Use a ventilated FIBC: When possible, use a bulk big bag with vents to dry the product before discharging. This helps prevent moisture-laden materials from sticking and accumulating near the discharge
