Dust control and containment is a key issue in equipment design and specification

Paul Boughton

As the use of FIBCs has risen, so the need for effective dust control has also grown. Containment of product is therefore of paramount importance today, particularly in respect of personnel, the environment and indeed to the product itself.

Consequently FIBC -- Discharging, represents the main area of failure if not properly designed and specified within the original equipment build, as a variety of things can happen here, where dependant upon the product and its characteristics, extremes of rapid flushing, to no movement at all can occur.
Accordingly a properly designed discharger will provide both effective dust control and efficient product containment, through a combination of features, such as a liner clamp to seal the bag or liner, right through to the collection hopper and a liner tensioning system, which supports total discharge of the bags contents and liner.
Furthermore, after discharging, the liner, or bag has to be removed in such a way, that containment is effectively maintained. Here the latest machinery, not only fully protects this operation, within a containment enclosure under partial vacuum, but also the operator.
Air extracted from the containment enclosure should also be passed through an absolute filter, which itself is designed to be emptied periodically without risk.
Although it sounds complicated, equipment today, provides the opportunity to maximise the many benefits from FIBCs especially in a safe and efficient manner.
