DESIGN STUDY FOR KUMBA SISHEN TRIPPER AUTOMATION


The Sishen Dewatering Bunkers in the DMS Plant are not automated and this leads to spillage cause by operator error. High volumes of spilled ore at the Dewatering Bunkers cause a safety risk due to the conveyor pull rope cables getting buried underneath the spillages.

Hamar Controls was awarded the contract for the E, C&I design from Kumba. The scope of work entailed designing of a solution whereby the tripper car will automatically move from one bin to the next as each bin is filled without requiring a manual action from an operator; design a solution whereby the dewatering bunkers are automatically unloaded at the completion of a drying cycle without requiring a manual action from an operator; reducing spillage caused by human error; control drying times in the dewatering bunkers; adding the technical capability at the DMS dewatering bunkers to allow for process monitoring and control; improve the mean time to failure of mechanical equipment such as the Tripper Car drive and reduce wear on the Dewatering Bunkers.
