HartikainenOyhas comeupwith an
unusual breaker/carrier combination
to carryoutwall scalingoperations at the
Siilinjärvi phosphatemine inYara Suomi, one
of theworld’s largest producers ofmineral
fertilisers. A1,300kg (2,860 lb)Rammer 2155
hammer is beingusedmountedon a 52 tonne
Cat 345CL carrier insteadof themoreusual
carrier in the 16 to26 tonne class. In addition,
theCat is also fittedwith a lengthenedboom
that allows it to reach to26m (85.3 ft). The
faceheight at themine is 14m (46 ft), which
means that for scaling the boomneeds tobe at
least 1.5 times longer than this height.
Hartikainenhasworked as a contractor at
Siilinjärvi since 1979, employing some 200
people in the area, and currently carries out
drilling, loading andhaulingoperations of
apatite andwaste rock at themine’s twoopen-
pit quarries under a long-term contract. The
company’s fleet of 96 to140 tonpayloadhaul
trucks shifted32million tons of rock last year
alone. Excavation recordswill bebroken again
in2015, given thehigh amount of surface
waste rock as themineneeds tobe expanded
togain access todeeper lying reserves. The
ore content begins to increase at around100
m (330 ft), fromwhichpoint theproportion
ofwaste rockgraduallydecreases.

Scaling the

Metso hits
for six
Shimizu Corporation will take delivery
of six LT 120 Lokotrack mobile jaw
crushers to assist with amajor landfill
project that it is carrying out in the
Tohoku region of Japan. The LT120's
were sold by Metso's Japanese
distributor UBEMachinery Co. Ltd., who
will also take care of the service and
parts related tasks, and will be used to
crush 6-7million tonnes of aggregates to
a tight project schedule.
The 2011 earthquake and tsunami
caused significant sinking of the ground
level in several coastal areas in the
northern part of Honshu island and
before new construction works can
begin, the level has to be raised by
several meters with aggregates.
The Lokotrack LT120 is built around
the proven C120 jaw crusher.With
its 1,200 x 870mm (4 x 2.9 ft) feed
opening, the jaw can accept even large-
sized boulders as feedmaterial. The
LT120 weighs 60 tonnes and is powered
by amodern 314 kW (421 hp) Cat C13
diesel.
The Lokotracks are being
manufactured at Metso's facility in
Tampere, Finland, and will be delivered to
Japan in spring 2015. At the sites in the
Tohoku region, they will be operated as
single units producing 0-200mm
(0-8 inch) aggregates for landfill.

Electric sorting
An electricallypoweredSennebogen821
Electromaterial handler, deliveredby
dealerKuikenN.V., is providinghandlingof
construction anddemolitionwaste at Baetsen
Recycling’s facility inSon, theNetherlands,
where the companyoperates twomodern
sortingplants on an8.5hectare site.
At theEkkersrijt facility inSon, thewaste
delivered to the site is sorted into21partial
flows, with the 821Electropositioned at the
start of theprocess chainwhere it carries
out thepre-sorting into eight different
graded categories. Themachine is positioned
centrallyon a ramp, allowing the operator
a clear viewof the area and the 11m (36 ft)
reachprovidedby the 821provides safe access
to all sortingboxes. Themachine is inuse 10
hours aday and is therefore capableof sorting
120,000 tonnes ofmaterial per year.
According to facilitymanagerMarc
Peperkamp, the 821Electroprovides a saving
of up to50% inoperating and energy costs
over the standard excavator it replaced,
alongwith lowermaintenance costs and less
downtime becauseno refueling is required.
Thanks to its robust crawler undercarriage,
A Sennebogen 821 Electro carries out
pre-sorting duties at Baetsen’s Son
recycling facility in theNetherlands
themachine is not only extremely stablebut
alsomoves easily along the sortingboxes.
It is not just the specialmaterial handling
characteristics providedby itsULM stick and
sortinggrab, but also the extended reach that
are additional advantageswhen compared
with thepredecessormachine. Supplemental
LEDheadlights andmultiple surrounding
cameras offer an ideal all-round view, even in
badweather.
