AMMJ Mill Downtime Tracking 40
PRIORITIZING AND ADDRESSING OUR PROBLEM AREAS
The following is the guideline of how to
go about addressing further the identified
dominant issues. At the equipment level
drill down to identify the dominant failure
cause of each equipment. Rank Top
5 by cost and Top 5 by frequency. If a
dominant cause appears in the Top 5 of
both lists then it will be given priority for
addressing immediately.
As an example of the different ranking
criteria described above, refer to Figure
11 and Figure 12 respectively.
Optimum solutions will be selected for
addressing the problem areas. The
solutions must prevent recurrence,
improve/sustain Mill Availability and most
important of all be within our control.
Having done that it does not mean that
other failure causes which have made
the Top 5 of either list are ignored. They
will only be given a lesser priority.
There are some clear-cut one-of events
that could be overlooked. Also there are
the chronic recurring failures that should
not be overlooked either.
COMMUNICATE FINDINGS TO
MANAGEMENT
Figure 10 This is an example of the drill down facilitation created from MS Excel
Pivot Tables and shows further drill down for information provided in Figure 2.
Figure 11 Top 5 of SAG1 Mill equipment 0231ML01 sorted by Cost.
Figure 12 Top 5 of SAG1 Mill equipment 0231ML01 sorted by Frequency.
As a summary of the findings of this
analysis the Top 10 equipment of both
SAG Mills are listed in Table 10. These
equipment have appeared in both the
20% of equipment in the downtime
incidents lists and downtime hours lists
(That is, Table 2 and Table 5 for SAG1
and for SAG2 that is Table 6 and Table 9
respectively).
These results from the MDTDB analysis were communicated to maintenance management by way of a presentation
similar to [3]. This also included some of our strategies to address some of the equipment breakdown root causes.
