The screw that was used to transport fly ash to the mixing plant jammed every time. Mike, Bart, Gunther and Kristof of ACD disassembled this screw and removed it from its housing. The screw, as predicted, was jammed by a piece of iron. All parts were revised, measured, rebuilt and assembled. The head bearing has been burned and renewed!
This top performance has been rewarded as the screw turns again!
