Screener designed to close the gap between midrange and high volume

Screener designed to close the gap between midrange and high volume
With 130 square-foot of screen cloth totalled across both decks, the five-foot by 14-foot screen box of the “high energy” S130 vibratory flat-deck screening plant offers a very large screening area designed to give aggregate producers cost-effective, increased production capacity. Combined with a lower screening deck measuring a full five-feet by 12 feet, the S130 screen box provides a significant increase in production rates, compared to other screeners in a similar nominal range, according to McCloskey.

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-foot and 11-foot screening plants. These new screeners are designed to close the gap to let producers expand their business incrementally and at significantly lower cost.

To match the increased screening capacity, the S130 is equipped with a large 10.5 cubic yard hopper. 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 cubic yard high capacity hopper and a heavy duty live head.

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 five settings for the screen box angle ranging from 25 to 38 degrees, adjustable vibration stroke from six mm up to 10 mm, and shaft speeds adjustable from 950 to 1,130 rpm.

Conveyors on the S130 are engineered to maximize stockpiling capacity, with discharge heights up to 15 feet 11 inches on the side conveyors. The feeder and tail conveyors are a full 48 inches 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 engine, and the engine bay is designed for extreme service accessibility for screeners in this size range. Screen sections for the S130 are also interchangeable with screens for the S190 model, McCloskey’s new five-foot by 20-foot high-energy screening plant, and units are designed for minimal set up and tear down time.
