McCloskey International has introduced a new vibratory flatdeck screening system designed to give aggregate producers more cost-effective choices when they plan for increased production capacity.
With 130 sq. ft. (12 sq m) of screen cloth totaled across both decks, the 5- by 14-ft. (1.5 by 4.3 m) screen box of the S130 offers up to 25 percent more screening area than other models. Combined with a lower screening deck of a full 5- by 12-ft. (1.5 by 3.6 m), the S130 screen box provides a significant increase in production rates compared to other screeners in a similar nominal range, according to the manufacturer.
Previously, quarry and pit operators would have to commit to as much as 80 percent more production to achieve any increase in capacity from existing 10 and 11 ft. (3 and 3.3 m) screening plants. The new McCloskey screener closes the gap to let producers expand business incrementally and at a lower cost, the company said.
To match the increased screening capacity, the S130 is equipped with a large 10.5 cu. yd. (8 cu m) hopper — a typical capacity for other 20 ft. (6 m) screening plants. The “taper out” design of the hopper strongly resists bridging and includes a large remote controlled tipping grid as standard.
Options include a lengthened 13.5 cu. yd. (10 cu m) high capacity hopper and a heavy duty live head.
More Control, High Energy
The S130 screening plant is based on the new “high energy” screen box design developed by McCloskey to maximize available vibratory power with a longer stroke and heavy duty eccentrics. The screener also provides an expanded range of control over several key areas of the screening process. This improved control allows operators to optimize throughput for widely varied materials by fine-tuning the screener with:
• 5 settings for the screen box angle ranging from 25 to 38 degrees
• adjustable vibration stroke from 6 to 10 mm
• shaft speeds adjustable from 950 to 1130 rpm
Conveyors on the S130 are engineered to maximize stockpiling capacity, with discharge heights up to 15-ft. 11-in. (4.8 m) on the side conveyors. The feeder and tail conveyors are a full 48 in. (122 cm) wide, and the side conveyors feature deep chevrons and high angle troughing idlers to prevent material rollback and spillage. The tail conveyor features a drop-down design to simplify maintenance and screen changes.
The S130 is powered by a Caterpillar 100 hp (74.5 kW) engine. The engine bay sets a new standard in service accessibility for screeners in this size range. The bay provides ample room for technicians to stand and move inside, along with their tools and equipment. The cooling fan, filters, hydraulic tank and other routine service points are all within easy reach.
Screen sections for the S130 also are interchangeable with screens for the S190 model, McCloskey’s new 5- by 20-ft. (1.5 by 6 m) high-energy screening plant.
The S130 also provides increased portability, with minimal time required to prepare the plant for travel or set up at the work site.
Its “travel-out” guarded walkways are fixed in place and require no folding or disassembly for the screener to meet highway width restrictions. The fixed walkways also provide maintenance staff a more stable, secure work platform with easily accessible stairs.
A remote control track crawler base is standard for on-site transport and is available with a roll-in tandem axle bogie for highway travel without a float. The plant is also offered as a tandem-axle wheeled model.
