Features

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 is larger compared with ST272™.

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.

Lokotrack ST2.8 is ready for screening in minutes thanks to hydraulically operated conveyors and screen including a patent pending feeder mechanism. Lokotrack ST2.8 is 25% lighter than similar machines. Because the weight is lower,  transportation is easier. The fuel-efficient scalping process can be started with safe push buttons or by the optional Metso IC™ process control system.

Benefits

  • The high eccentric throw separates sticky material
  • Push button or optional Metso IC process control for safe operation
  • Extremely wide feed hopper with additional side walls

Process overview

Lokotrack ST2.8 is used as primary scalper in top soil and natural sand applications. It is suitable in multistage crushing processes to split the products eg. between secondary and primary crusher. With two way split the option it is a great unit in between of jaw and cone crusher. Depending on applications plate grizzlies, fingers, punch plates or wire meshes can be used on the top deck.

How it works

Material is fed by the excavator, wheel loader or conveyor.  The  feeder lifts material to two deck screen which then separates material to oversize and side conveyors. With two way split option top and bottom deck material can be combined to the oversize conveyor (fines removal).
