LATEST from Pilot Crushtec International is Metso Outotec’s Lokotrack® ST4.10™, the largest model in the Lokotrack® mobile screen range. With a nominal capacity up to 600 tons per hour (tph), it is ideally suited for high-capacity aggregate screening in a closed-circuit crushing process.
While static plants have always been preferred in high-volume aggregate applications, mobility and flexibility have become principal factors for aggregate producers, prompting the migration to mobile screens at several operations.
A major talking point is the plant’s extensive 9m² screen area with three 6,060 mm x 1,520 mm screen decks producing up to four end products. The wide feed box with an 8m³ capacity and the 10m side conveyors with adjustable angles and speeds, enable the unit to be deployed as part of a multi-stage crushing process in closed circuit with large scale crushing plants such as the Lokotrack LT120™ or LT300HP™.
The wide grizzly rock box also makes loading with a wheel loader easy when using the Lokotrack® ST4.10™ as a stand-alone unit in sand and gravel applications. Despite its large size and its 33t mass, the new mobile screen is fast and easy to set up. With its 19 650 mm (length) x 3 040 mm (width) x 3 560 mm (height) transport dimensions, it can be transported between sites as a single unit on a low bed truck.
The screen is equipped with a diverter chute that enables blending of products from different decks. Side tensioned top and middle decks make changing screening media quick and easy, thus maximising uptime on site.
As all Lokotracks, the Lokotrack® ST4.10™ can be equipped with the optional Metso Outotec IC™ process control system, which offers a safe single-button start-up and the possibility to interlock the screen with other Metso equipment in a train.
The new mobile screen is powered by a 106kW CAT C4.4 106 engine.
