New Powerscreen Equipment at North American Open Day
New Powerscreen and Terex Pegson crushing, screening, recycling and washing equipment was introduced to more than 100 dealer personnel and 75 of their customers at the “Open Days” demonstrations held May 11-12 at three customers’ sites in Dumfries and Fredericksburg, Virginia, near Washington D.C.. These included Potomac Landfill’s recycling operation (7 pieces of crushing, screening, shredding equipment), Ennstone’s Albion Pit dry crushing and screening operation (6 pieces of equipment) and a new washing plant (8 pieces of equipment) at Ennstone’s new Fulks Pit facility.

The new 1100 x 650 Terex Pegson Premiertrak XA400 jaw crusher features a hydraulic adjust system that provides for quick machine setting changes with no drawback rod adjustment. (Also available as the XR400 with hydraulic release system that opens automatically on overload, such as if a large piece of steel enters the crushing chamber.) Processes up to 350 tph with very low fuel consumption due to the highly efficient HFO direct drive system. Aggressive, high-swing jaw handles large feed. Hydraulic folding hopper for easy setup. Excellent under-crusher access with under-screen feeder option.
The new 20′ x 5′ Chieftain 2100 triple-deck rinser is a combined mobile screening and rinsing machine designed for optimum efficiency with “raw” materials and can produce up to 6 end products. It can produce a high tonnage of finely sized material within strict specifications such as for asphalt aggregates. Maximum access for easy maintenance and service. It can be converted to a dry screen by replacing the catchbox with a tail conveyor. The smaller Chieftain 1400 rinser produces 1 or 2 grades of sand—or up to 4 sized, washed products with an optional 2-deck vibrating grid on the feeder.
21′-2 ″ x 6′-4″ diameter drum has 4 panels with 5 meshes per panel, featuring Powerscreen’s quick-change mesh system. The 4-wheel friction drive far outwears conventional drives and facilitates quick removal and changing of the trommel drum, typically in about 10 minutes.
The new Powerscreen Orion 1400 trommel provides high mobility and sets up in about 15 minutes. Hydraulically folding trommel door allows for quick drum removal. High performance hydraulic system. Friction 4-wheel drum drive system. Hydraulically adjustable machine working angle. For topsoil, recycling, wood chippings and compost applications.
The Terex Pegson 1000 and 1300 Maxtrak cone crushers feature the exclusive Automax “all-in-feed” design for better throughput, shape and reduction for secondary, tertiary and quaternary use. Overall plant cost is reduced and the plant is much less complicated, since in most cases there is no need for prescreening between a primary jaw and the Automax. The design can effectively utilize greater engine power and has lower frictional loss, resulting in greater production and product quality with exceptional fuel economy. The crusher is designed to produce a more cubical product and can make road-base material in a single pass. The hydraulic system can be adjusted quickly and easily, even while crushing. No “bowl bounce.” Easy manganese changes.

The Chieftain 2400 track is Powerscreen’s largest dry screening plant, featuring true 20′ x 6′ direct-feed 2-deck and 3-deck versions and numerous options of volume processing of sand/gravel, coal, aggregates and crushed concrete/asphalt rubble. Up to 750 tph, depending on mesh sizes and material types. Has a 10mm adjustable stroke and adjustable screen angle. Four product conveyors stockpile fines, mid-size and oversize, plus a return conveyor to the crusher feed. Direct-drive feed conveyor has hydraulic variable speed control and features impact rollers beneath the feedboot impact point. Optional roll-in bogie for towing without a low loader.
The Powerscreen Finesmaster 200 sand recovery plant can produce one or two grades simultaneously at up to 200 tph. Virtually no saleable product is discharged to the pond system, thus increasing production and reducing pond maintenance. Smaller 120 and 60 tph models are also available. Finesmasters recover 96-98% of all material above 200 mesh and 100% above 100 mesh. The Finesmaster 200 incorporates high-capacity twin bucket wheels with variable speed control up to 3.3 rpm, a centrifugal slurry pump, a collection tank and 2 rubber-lined hydrocyclones with fixed-spigot discharge to a split (coarse and fine product) dewatering screen. Each 8.5′ diameter wheel has 14 buckets with a capacity of 0.14 yd3 each.
The high-speed Powerscreen Powerscrub 120 takes washing one step further. Scrubbing works on the principle of working material against material to remove clay and other material from the stone before going to the next stage. Optional sieve bends can be added to suit recycling applications to separate floating contaminants. The Powerscrub 120 utilizes 2 inclined rotating shafts which rigorously mill and agitate the material. The material bed in the hull prevents wear in the steel trough. An elevated spray bar constantly adds water to the material. Agitation encourages light particles, silt and clay to float through the water exit.
