Lokotrack® ST2.8™ mobile scalping screen is often used as primary scalper in top soil and natural sand applications. It is suitable in multistage crushing processes to split the products between secondary and primary crusher.
The scalping screen is fed by the excavator, wheel loader or conveyor. The feeder lifts the material to two-deck screen which then separates material to oversize and side conveyors. With two-way split option the top and bottom deck material can be combined to the oversize conveyor (fines removal).
Fast set-up time
Lokotrack® ST2.8™ mobile scalping screen is ready for screening in minutes thanks to hydraulically operated conveyors and screen including a patent pending feeder mechanism. It is also lighter than similar machines making the transportation easier.
The stickier the feed material, the more throw needed in the scalping screen. Lokotrack® ST2.8™ has the biggest eccentric throw on the market to make it the best unit for the screening of top soil, demolition waste and river gravel.
Additionally, ST2.8 can be fine-tuned even for sand applications. The clearance under the screen has been increased by 20% and the bottom deck area made larger as well.
Easy to operate
The fuel-efficient scalping process can be started with safe push buttons or by the optional Metso IC™ process control system.
In multi-stage crushing processes, the removal of fines is easy with a two-way split option. This feature combines material flow from the first and second deck to the main conveyor and maximizes the capacity and efficiency of the crushing process.
Belt feeder and chevron belts are standard features of Lokotrack® ST2.8™ mobile scalping screen.
