The ST620's DS series high-performance triple deck screen has been developed for the highest capacity in mobile applications. A large screen deck area for all three decks and a steeper inclination angle at the loading end are standard features of the ST620, designed to guarantee you the best output.

Screening accuracy is ensured by a shallower angle at the discharge end. The hydraulically driven screen can be equipped with a wide range of screening meshes to suit different product sizes and requirements.

The market leading Metso IC™ process control and diagnostics system, a standard feature of the ST620, offers single-button start-up and the possibility to interlock ST620 with other Lokotrack crushing and screening plants. It continuously monitors unit functionality and protects from misuse. Metso IC improves your screening efficiency and makes the ST620 safer and easier to operate.


  • Triple deck and dual-slope screen for four end products
  • Great mobility on quarries and construction sites
  • Engineered to work in combination with Lokotrack units

Process overview

Lokotrack ST620 is used in aggregate production, to create high production and precise screening.

How it works
