SCHENCK Australia has released the JCI Fast Trax 6203 track-mounted horizontal screens. It is a 1.8288m x 6.096m, three-deck screen on a track-mounted carrier.
The plant incorporates a rear-feed hopper that allows it to be directly fed with a loader or excavator. The rear hopper wall can be removed to allow a track-mounted primary plant to feed the screen plant.
The 6203 also features an end delivery conveyor for the top deck overs, which can feed directly into another track plant or create a large stockpile. The centre and bottom deck overs and fines each have individual discharge conveyors, which allow 3m stockpile heights. The centre and bottom deck overs can also be blended together and discharged out the opposite side from the fines, allowing the plant to produce windrows.
A horizontal screen provides a slower and more consistent travel speed, while reducing the wear and tear on chutes and conveyors that must catch the material off the screen. An incline screen tends to accelerate material as it moves down the deck.
A horizontal screen has increased screening efficiency and ability to scrub out nearsize particles and reduces the potential for material to bounce or spill off the decks, posing safety hazards to the operators.
The 6203's low profile screen design does not require additional hydraulic cylinders and components to raise or lower an incline screen for transport. The three-shaft design provides high G-force oval motion screening that reduces the potential for plugging and binding on the decks. The design also spreads the bearing load over a wide area, reducing basket stress compared to a single shaft/bearing arrangement.
