Conductive Bulk Bag

This can be achieved with either passive (single pole clamp and cable) or active means (monitoring systems), but given the scale of the charge that can build up on bags and the resulting energies that can be reached by static sparks, in combination with the presence of a combustible dust cloud, an active grounding system is the better choice.

This is because the system can determine whether or not the bag's construction complies with the recommendations of the standards highlighted above and will also ensure the bag is grounded for the duration of the filling / emptying operation. The primary benefit of checking the resistance through the bag is to ensure that after many cycles of repeated use, the static dissipative threads are functioning correctly and, more importantly, to ensure that bags not of conductive construction are not permitted to be used in the hazardous area. Additional benefits with grounding systems are that they can control the movement of the powder through output contacts interlocked with valves or PLCs.

Following the connection of two quick release clamps, the FIBC system will identify if the bag is operating in accordance with the relevant standard. This is achieved by sending an intrinsically safe signal through the bag. If the green ground status indicators pulse continuously, the operators know the bag is grounded. The system verifies the grounding of the bag by ensuring the signal returns via a verified true earth ground. If there is any charge on the bag it will leave the bag via the static dissipative threads to the verified ground. If the output contacts are interlocked with the process then the material cannot flow without the permission of the operator.

The purpose of conductive bulk bags is to keep static electricity from building up while being transported and stored. They are perfect for items that are categorised as explosive or flammable, like chemicals (sulphur, coal dust, or specific fertilisers) that come in powder, granule, or flake form. Conductive bulk bags are made from a special type of fabric that securely disperses static charge to the ground because it is woven with conductive threads, such as carbon or stainless steel fibres. To further reduce static build-up, conductive bulk bags frequently include grounding straps or loops that attach to a grounding system.

On the other hand, ventilated bulk bags allow air circulation within the bag. They are designed to facilitate appropriate ventilation and avoid moisture build-up. These large bags are perfect for goods that can become spoiled or grow mould when there is a buildup of moisture, including agricultural products, such as grains, coffee beans and seeds. Ventilated bulk bags are made from a woven fabric that has mesh panels or breathable strips to promote airflow. By allowing trapped moisture to escape, the breathable design stops mildew and mould from growing on the objects that are being stored. Good ventilation keeps products that are prone to spoiling fresh and of a high quality.
