1. The product to be discharged is completely free flowing, thus requiring no flow aids.
2. The product is dust free and thus requires no containment.
3. Uncontrolled 'choke feeding' from bulk bags is acceptable, thus no other regulation of the flow is required once the neck ties are released.
4. There is the continuous presence of an operator.

Good H&S practice requires, as a minimum, that the weight of a bulk bag be supported as it is unacceptable to support bags from their loops for any length of time where operatives are present. It is certainly not good practice to use a fork lift truck to hold a bag over a point of discharge. Additionally, it ties up the fork lift preventing it from being used elsewhere.

Our Simple Bulk Bag Discharger Support Frames are robust and can be constructed from epoxy painted carbon steel or stainless steel as the environment dictates. Bulk bag loading can be by fork lift truck or hoist.

Spiroflow will only offer Simple Support Frames for those applications where we are confident of their suitability. We have so much experience that the design of even our simplest support frames benefit from this. As mentioned previously, in all but for a very few applications, gone are the days where a local fabricator or a company's engineering team can 'knock up' a simple bulk bag discharger 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.
