We are currently installing a bulk bag (super sack) filler for a mix that we make and then use to make a finished good. The filler has metal detection on it. We intend to challenge the metal detector on an hourly basis, but are struggling on how to handle the material in the event that the metal detector fails to detect the test piece. There is no way, currently, to rerun the mix back through the metal detector. Looking for how other facilities that have metal detection on bulk bag fillers handle a failed metal detector. Any ideas would be greatly appreciated.
