The Powerscreen Horizon 6203 dry screening plant is designed for large-volume processing of crushed stone, sand/gravel, coal and recycled concrete and asphalt.

The plant has a capacity of up to 800 tons (726 t) per hour, and it features a 20-ft. by 6-ft. (6.1 by 1.8 m) triple-deck with high-productivity geared triple-shaft, oval-stroke — adjustable forward and elliptical .5- to .75-in. (1.3 to 1.9 cm) throw — screen. These screen motion variances allow operators to adapt the plant to specific applications, providing high resistance to pegging and blinding, and with high energy characteristics to loosen fines. On-site setup time is approximately one hour.

The 10.73-cu.-yd. (8.2 cu m) feed hopper is equipped with impact bars and rollers and has Hardox 400 steel side and back plates, which fold hydraulically for transport. A double-deck roll-in chute system with hydraulic trap doors enables operators to blend material grades and produce specific end products.

The four angle-adjustable stockpiling conveyors fold hydraulically and have variable belt speed control.

All major areas of the Horizon 6203 are easily accessible for maintenance and screen change. Extended maintenance intervals reduce downtime and gear case baffles and hub oil ports reduce vibrator temperatures. There are high-strength screenbox side plates and the triple-shaft screen has HD belts that test to five-times life over conventional belts, plus high performance gears with optimized tooth geometry. Non-contact rotary gland shaft seal outperforms and outlasts conventional lip-contact seals, according to the manufacturer.

The plant is powered by a Deutz 174-hp (130 kW) diesel and equipped with heavy-duty, high-performance Danfoss and David Brown hydraulic pumps and motors.
