- Will the Bulk Bag Discharger handle poor flowing products?
- Is there a fork lift truck available or is an integral hoist needed?

- Does the Bulk Bag Discharger discharger have a device to keep the bag under tension during discharge to ensure all product is discharged?
- Is discharge of bag contents required by weight or by volume?
- Is there provision for restraint and/or removal of inner liner?
- Is an integral take-off conveyor required?
- Is there a height restriction?
- Is there provision for emptying small sacks in case the bulk bag supply is interrupted?

- What dust control features are incorporated into the Bulk Bag Discharger?
a. when untying the bag spout
b. whilst the product is being discharged
c. when the inner liner is being removed
d. when the bag is removed and folded for disposal - Is the product or environment hazardous, there needing provision for containment with static grounding and monitoring?

Many of the answers to these questions appear on the following pages. Also see our Technical Article 'Discharging Bulk Bags - a practical guide to dust containment and static control'.
In all but for a very few applications, gone are the days where a company can ask a local fabricator or their engineering team to 'knock up' a simple bag support frame. These can never match the safety, reliable discharge and containment offered by the specialist supplier and demanded by today's practices and legislation.
