ABSTRACT
The fertilizer bagging line operation for packaging and conveying to the final delivery trucks was a source of problem for one fertilizer producer referred to here as Company ā€œNā€. This resulted in frequent maintenance activities from constant machine breakdown, loss of production, and the attendant loss in plant revenue. To overcome this, a technical study was conducted to address the problem. Plant site visit and technical inspection revealed the breakdowns were primarily due to fertilizer granules being trapped on the packaging/bagging conveyors, and as a result of fast acidic corrosion causing rust and eventual seizures of the conveyor rollers and lines. The resistances to free roller movement induce a drag load on the drive motors, with the additional loading causing failures of the electronic control sensors and stoppages. The unreliability of the bagging operations in the unplanned, repeated start-stop sequence in the packaging operation also led to safety concerns, with a few incidences of injuries being recorded. The engineered solution is presented in this report.
