ABSTRACT
This project describes a total productive maintenance (TPM) implementation at the Weir
Minerals Africa Isando plant where previously a critical machine experienced a breakdown
lasting 30 minutes or more every day. A system was created to track the number of
breakdowns and availability of critical machines. The proposed solution consists of a report
card for each critical machine, which includes a machine diagram, the frequency of
breakdowns, a root cause analysis, a list of critical spares and a planned maintenance
schedule. The proposed solution is a starting point upon which a comprehensive preventative
maintenance program will be developed.
