High Volume Screening Plant Angled for Max Production

Tue July 10, 2007 - National Edition

McCloskey International has introduced a new vibratory flatdeck screening system for portable plant operations.

The S190 screener features a 5- by 20-ft. (1.5 by 5.1 m) “high energy” screening box engineered to allow the industry’s steepest screening angles for any portable plant of similar nominal size. Its adjustable screening angles combined with increased vibratory power and a large effective screening area of 190 sq. ft. (17.6 sq. m) raise the maximum throughput in portable plants.

McCloskey’s newest heavy-duty flatdeck plant also offers greater control to fine-tune the plant to the task at hand:

• 5 settings for the screen box angle ranging from 20 to 30 degrees

• A “high energy” screen box with adjustable vibration stroke from 6 mm up to 10 mm

• Shaft speeds adjustable from 950 to 1,130 rpm

The productivity of the S190 is enhanced by features designed to minimize downtime for travel, set-up and service. Its “travel-out” guarded walkways are fixed in place and require no folding or disassembly for transport. The track-mounted machine is offered with an optional roll-in bogie for highway travel without requiring a float. The plant also is available as a tri-axle wheeled model.

After the screener arrives on site, set-up can be completed in as little as 10 minutes. No tools are required to ready the screener for production from transport mode. While the fixed walkways speed setup time, they also provide maintenance staff a more stable, secure work platform. When screen changes are required, the tail conveyor drops down out of the way for easy access to the bottom of the screen box.

The S190 is powered by a 125 hp (93 kW) Caterpillar engine. The design of the engine bay provides ample room for technicians, along with their tools and equipment, to stand and work comfortably. The cooling fan, filters, hydraulic tank and other routine service points are all within easy reach.

The large 10.5 cu. yd. (8 cu. m) “taper out” hopper resists bridging and is equipped with a remote controlled tipping grid. Options include a lengthened 13.5 cu. yd. (10 cu. m) high capacity hopper and a heavy duty live head.

Conveyors are engineered to maximize stockpiling capacities, with up to 17-ft. 3-in. (5.3 m) stockpile height on the side conveyors. The feeder and tail conveyors are a full 48-in. (122 cm) wide, while the side conveyors are equipped with 32-in. (81 cm) wide heavy chevron belts and high-angle troughing idlers to prevent spillage and material rollback.

The lower screening deck, at a full 5- by 18-ft. (1.5 by 5.5 m), provides an increase in effective screening area compared to other screeners in a similar nominal range. This combined with the ability to adjust the screen box from 20 to 30 degrees further enhance the productivity of this machine on the job sites. Screen sections for the S190 also are interchangeable with screens for the S130 model, McCloskey’s new 5- by 14-ft. (1.5 by 4.3 m) high-energy screening plant.
