NEW METSO MOBILE RANGE UNVEILED
Introducing the ST272, ST3.5 and LT110C models

Metso Mobile’s comprehensive Lokotrack crushing and screening series has now been expanded following the recent introduction of three additional models built to meet the high tonnage demands and different customer application challenges of the local market. Sold and supported by southern African Caterpillar dealer, Barloworld Equipment, the new models, which comprise the Lokotrack ST3.5 and ST272 mobile screening units, and the Lokotrack LT110C mobile primary crusher, are all produced at Metso’s manufacturing facility in Tampare, Finland. (Metso is a global supplier of a range of solutions for the mining, construction and general industry.)

As with all Metso machines, the design philosophy from the ground up is on delivering the lowest, sustainable, cost per ton in the most demanding mining and construction environments. Metso has gained extensive experience in this field and was the first company worldwide to start the serial production of mobile crushing and screening plants back in 1985. Since then more than 5 000 Lokotracks have been sold globally and ongoing research and development continues to be based on the extreme hard rock conditions typically found in Finland and the surrounding Nordic region. Innovative features such as Metso’s IC (Intelligent Control) software systems refine this process still further with full plant automation capabilities and real-time diagnostic feedback. “The ability to field a broad range of Metso Mobile solutions dovetails well with our Caterpillar product line,” explains Trevor Garden, general manager: Metso at Barloworld Equipment. “This means that we can structure packaged solutions for our customers that include Metso machines along with Cat excavators or wheel loaders as the loading tools.” “In addition, since Metso has decided to standardise on Cat engines across its entire mobile range, we are also well positioned as the local Caterpillar dealer to provide comprehensive after-sales support,” Garden continues.

LOKOTRACK LT110C PRIMARY CRUSHER
Designed for primary crushing, Metso’s new Lokotrack LT110C is built around the world famous Nordberg C110 jaw crusher, which has a feed opening of 1100 x 850mm. Power is supplied via a 310 kW Cat C13 diesel engine and the machine has an overall operating weight of 58 tonnes. “Sold locally with a 9m3 feed hopper this deep jaw configuration and large feed size is ideal for crushing hard and abrasive materials, making it well-suited to our local conditions,” Garden explains.

“A key feature of the LT110C is its crushing efficiency since the feeder’s grizzly screen deck ensures that you only crush what needs to be crushed. With a mesh setting of 53mm, around 30 to 50% of the extraneous material passes through the grizzly, which optimally lowers the cost per tonne.”The LT110C is fitted with a 14m folding conveyor with a discharge height of 3,7m (as standard for our Africa market), making it an optimal match for the Lokotrack LT300HP cone crusher. (In fact, the LT110C can easily be combined with all secondary and tertiary crushing plants and mobile screens in the Lokotrack series.)

LOKOTRACK ST272 SCALPING SCREEN
Launched for the first time in 2008 at ConExpo in Las Vegas, the Lokotrack ST272 has been an instant success due its exceptional versatility. From efficient primary scalping to the accurate screening of fine end materials, such as natural gravels, crushed rock, soil or recycle materials, the new Lokotrack ST272 is well equipped for the task, with the unit driven by its Cat 4.4 engine. With an overall weight of 34 tonnes, the ST272 is built around a heavy-duty two-deck two-bearing screen design. The screen box dimensions are 4 866m x 1524m with a screening area per deck of 6,6m2. The standard ST272 is capable of producing three classified fractions, with the screen accepting feed material of up to 600mm. (The machine’s robustly built apron feeder lifts the feed material onto the screen and operates through an electrically controlled hydraulic drive.)

LOKOTRACK ST3.5: THE SAND PRODUCER’S CHOICE
Joining the ST272 in southern Africa, the Lokotrack ST3.5 mobile screen is a new global release by Metso with units reaching the market for the first time from the fourth quarter of 2010. Locally, Garden says that the ST3.5 is expected to prove especially popular with sand producers. It now joins the larger ST3.8 model introduced to South Africa earlier in 2010.“Metso Mobile’s simplified ST naming policy now clearly identifies the performance profile of each mobile screen,” says Garden. On the ST3.5, for example, ‘S’ stands for Screen, ‘T’ for Track-mounted, ‘3’ for the number of discharge conveyors, and ‘5’ for the screen area per deck to the nearest whole number in square metres (which in this case is 5,3m2). Purpose-built for cost-effective operation and powered by a 75 kW Cat 4.4 engine, the Lokotrack ST3.5 is equipped with an aggressive 3 580mm x 1 500mm screen box. The unit has four identical meshes, which can be swopped around as needed to minimise the longer-term wear impact.To suit the profile of the target market for this screen, it is manually controlled and does not have the more advanced features of the IC system like the larger ST3.8. This means that this particular screen is priced very competitively for this market. Adds Garden: “From the onset, profitable operation is the overriding design factor for all Metso crushing and screening systems to ensure that targeted product throughputs are achieved whilst at the same time keeping processing costs to a minimum.”“The three new Metso models joining our current line-up are manufactured to do just that, with the added assurance for customers of excellent after-sales support via Barloworld Equipment’s extensive branch network in southern Africa.”
