Unreliable and time-consuming methods
of monitoring the condition of mill liners
are no longer necessary as mines can now
ensure higher efficiencies by tracking liner
wear in real time.
With the introduction of MultoScan by
Multotec Rubber, milling plants can accu-
rately measure a mill’s liner profile and
predict the point at which the mill will start
becoming inefficient. The automatic mea-
surement and display of the charge level
confirms that the operation of the mill is
correct.
According to Matthew Fitzsimons,
Technical Manager at Multotec Rubber,
wear rates of liners are not linear, as the
increased slippage of the charge on worn
liners tends to exponentially increase the
wear rate.
Data generated by the MultoScan is
analysed and interpreted by highly skilled
technicians using Multotec’s Hawkeye
proprietary programme so there is no
time lag, allowing plants much quicker
responsiveness.
“When combined with critical mill
operating parameters, this data can help
predict the point where the liner becomes
inefficient and hence when the mill itself
will become inefficient,” says Fitzsimons.
“Customers can receive immediate feed-
back on the condition of the liners, so
any urgent issues can also be timeously
addressed.”
The traditional way of monitoring
liner wear was the time-consuming and
often inaccurate pin-gauge method. The
MultoScan now provides an effective
alternative, while also being much more
affordable than the highly sophisticated
but expensive monitoring technology in
the market.
Repeatability of the MultoScan results
MultoScan tracks mill liner wear in real time
means that there is hardly any room for
human error in this system. It also saves
mines significantly in terms of the time
value of mill stoppages for taking manual
wear readings.
Further savings can be harnessed by
reducing the stockholding of liners that
mines need to keep; this is due to better
information on the liner profile, giving
maintenance crews the ability to set the
trigger point for the liner inventory as and
when they need it.
Fitzsimons highlights the potential that
MultoScan offers, as individual plants can
map key performance indicators of their
mills and link these to the liner profile
condition, extending the capability of the

Dundee Precious Metals and MineRP join forces
TSX-listed Dundee Precious Metals Inc
(DPM) has announced that it has entered
into a definitive agreement with MineRP
Holdings, a provider of integrated min-
ing technical solutions. In terms of
the agreement, DPM will combine its
proprietary wireless underground com-
munications technology, managed within
DPM’s Terrative Digital Solutions division,
with MineRP, and acquire a majority inter-
est in MineRP.
MineRP, a private company founded in
1997 and headquartered in South Africa, is
an independent software vendor (ISV) for
the mining industry. Its unique platform
improves productivity in planning and oper-
ations by integrating various technical and
financial applications in the industry. Since
2011, DPM has also established itself as a
leader in digital innovation across its asset
base, particularly at its Chelopech opera-
tion in Bulgaria where it developed wireless
underground communications technology
which is held within Terrative. DPM also
owns the Tsumeb smelter in Namibia.
With the August 2017 release of MineRP
4.0, MineRP is in a position to extend its
data-integration capabilities to real-time
operational monitoring and control. For this
purpose, the cost effective, robust commu-
nication and data acquisition technologies
developed by Terrative, combined with
MineRP’s solutions, will offer the mining
industry a fully integrated communications
platform and information management
framework.
“MineRP has always been at the forefront
of innovation focused on the Enterprise
Big Data in mining. Combined with the
advanced digital communication technolo-
gies offered by Terrative, MineRP’s enterprise
solutions provide a revolutionary platform
for robust digital transformation for mining.
The transaction provides MineRP with the
means to aggressively implement our Spatial
Enterprise Integration strategy across the
globe,”comments Pieter Nel, CEO of MineRP.
