MODERN QUARRYING
January - February 2014
Several months of experience producing
consistently high volumes of quality prod-
uct has, in fact, proved quite the oppo-
site. The Rubble Master has significantly
driven down operating costs as it works
free of the complexities of a conventional
crushing and screening train.
Pilot Crushtec International national
sales manager Nicolan Govender explains:
Metso’s latest-generation Lokotrack ST2.4
mobile screen combines high-capacity per-
formance with fuel-efficient operation. The
company claims this provides the lowest cpt
in its class, thanks in part to the optimised
hydraulic design and state-of-the-art pro-
cess steering automatics.
The Lokotrack ST2.4 processes a diverse
range of feed materials, from the pre-screen-
ing of the coarsest gravel to fine classify-
ing and processing of natural sands, or any
demanding recycle materials. Three clean
end product sizes can be produced in one
process due to the unit’s two-stage screen set
up. A variety of screen media can be fitted,
from steel meshes to rubber and polyure-
thane materials. All the conveyors are folded
hydraulically and sealed mechanically.
The Lokotrack ST2.4’s screen box size
measures 3,6 m in length with a width of
1,5 m. Machine and track systems are pow-
ered by a 74,9 kW Cat C4.4 diesel engine.
Optional features on the unit include a
vibrating apron feeder with grizzlies or fin-
ger bars, a lamer feeder, magnetic separator
for recycling, and remote radio controls.
Designed for on-road transportation, the
25 t Lokotrack ST2.4 is 14, 2 m long, with a
height and width of 3,4 m and 2,9 m respec-
tively, enabling rapid deployment between
sites.
When KwaZulu-Natal aggregate producer Flanders Quarry bought
a Rubble Master RM80G GO! To produce large amounts of G4 and
G5 material, it flew in the face of traditional opinion concerning the
supposedly high running costs of horizontal shaft impact crushers (HSI).
RM80 GO! –
dynamite in a small package
“The product supplied was a conventional
RM80 GO! fitted with an MS80 GO! Screen
as a factory-fitted extra. The customer can
now use a single compact machine to
product G4 and G5 material in quantities
that previously required three different
pieces of equipment: a jaw crusher, cone
crusher and screen.”
He says the economic implications
speak for themselves. “A single power
plant replicates the work previously done
by three separate units, which garners
potential savings in diesel consumption,
maintenance and labour costs. Wear to
internal components has also proved to
be minimal.”
Flanders Quarry thought long and
hard before making a long-term commit-
ment with the purchase of capital equip-
ment. “Being a fairly small company, we
decided to gain experience by hiring a
variety of machines before taking the
plunge ourselves. While it took over two
years to finally make our decision, we
have absolutely no regrets about the out-
come,” says MD Karl Stott.
The Mount Edgecombe -based
The versatile Rubble Master RM80 GO! is proving
its worth at Flanders Quarry in KZN.
company has been active for nearly two
years but the drive to seriously step up
production came with the awarding of
two major contracts to produce G4, G5
and G6 materials for bridge and civil con-
struction. It was originally in the market
for a scalper; however, Pilot Crushtec’s
advice was that its potential customer
would be best served by a solution elimi-
nating the need for a multi/crusher screen
train. The state-of-the-art Rubble Master
RM80 GO! was an obvious choice as the
Austrian product, fitted with a screen,
contains all three capabilities packaged
within a single unit.
Following discussions with technical
staff at the supplier’s Jet Park facility and
a site visit to a local operator, the Pilot
Crushtec International sales teamarranged
for truckloads of Flanders Quarry dolerite
material to be processed by a RM80 GO! to
G4 and G5 spec at one of their customer
sites in Pietermaritzburg, resulting in the
immediate purchase of a unit.
“The machine is doing a great job pro-
ducing more than 150 tph on a 0-200 m
decomposed dolerite,” Govender says,
adding that the MS80 GO! screen gives
the ability to produce a range of products
from G2 to G7 in accordance with Colto
and TRH14 specifications. The opening
of the closed side setting on the screen
saves significant wear on the crusher’s
hammers.
Scott is very positive about his new
supplier. “Pilot Crushtec International is
a well-established and progressive com-
pany with a strong service orientation.
This extended to flying out a technical
expert from the Rubble Master factory in
Linz, Austria, to assist with the product
set-up.”
He is upbeat about business pros-
pects in the area. “We are in the right
place at the right time. There is an enor-
mous amount of local development and
our order book shows that we can look
forward to the next couple of years with a
great deal of enthusiasm. We believe that
the future business climate will favour
small to medium-sized companies like
ourselves and the availability of products
like the Rubble Master RM80 GO! allow us
to be competitive in our field.”
