Powerscreen Warrior 1800 in Hurricane clean up
Hurricane Charley (Sept '04) wreaked massive damage on its destructive path across Florida last month, providing a stark reminder of the similar results of Hurricane Isabel which tore across Cape Hatteras, North Carolina last year, with winds of up to gale force 10. Powerscreens Warrior 1800 was sent in to clear up.
Man-made sand dunes, created as a first line of coastal protection for local inhabitants on Cape Hatteras Island, were scattered and thoroughly mixed with concrete and asphalt rubble, as well as timber, glass, stone and other debris from over 100 homes, hotels and other structures which were destroyed by the path of Hurricane Isabel.
In the aftermath of this destructive force, the clean-up process produced many difficult challenges - not least of which was the recovery of the sand, rebuilding of 1.8 miles of protective dunes, extraction and recycling of the destroyed buildings’ rubble and waste to produce material for backfill where the land had been eroded.
Crowder Gulf Disaster Recovery and Debris Management came up with the ideal solution by bringing in a heavy-duty Powerscreen Warrior 1800 dry screening plant to carry out the arduous task of material screening and separating, stockpiling and reclaiming. Around 100,000 cubic metres of sand was processed at a rate of 5,000 cubic metres per 18-20 hour day, producing a 95% sand recovery with a 5% extraction of contaminant debris.
Scattered sand and debris was collected and trucked to a recovery site where the Warrior 1800 screened and separated the mix with a three-way split via conveyors to stockpiles. Oversize material was used to fill in eroded beach and other areas; mid-sized material was utilized to cover the fill and the fines (recovered sand) was deployed to recreate the 1.8 miles of sand dunes. Grass seed was liberally applied for extra strength and soil stabilisation.

Crowder’s Project Manager Todd Missildine called in Powerscreen Mid-Atlantic to advise and supply the best machine for the job. “Powerscreen equipment was my first and only choice”, he said. “I knew the equipment from previous jobs and I had to get the project started straight away. Calling Powerscreen Mid-Atlantic was an easy decision”. Owner and President of Powerscreen Mid-Atlantic, Andrew Coney, recommended using the Warrior 1800 because of its versatility in handling fine screening as well as C & D waste simultaneously. The remote controlled tracked chassis also provided the added benefit of site mobility, which was to come in very handy even before the machine made it to the jobsite. As soon as the go-ahead was given, Andrew Coney was faced with a real problem as to how to get the Warrior 1800 to the site because the roads were impassable and, in some places, covered by up to a metre of sand!. “The North Carolina Department of Transportation supplied us with a heavy-duty ferry” Coney thankfully related “and we were able to track the Warrior straight onto the vessel and ship it over to Hatteras Island”. Powerscreen Mid-Atlantic had the Warrior 1800 on site, up and working within two days,
The Warrior 1800 is built for tough, high capacity tasks in processing sand, gravel, topsoil, coal and crushed stone and C & D waste recycling. Highly mobile with low ground pressure crawler tracks and aggressive in operation, the machine is capable of screening, three-way splitting and stockpiling and, typically, can be set up ready to run within 15-20 minutes of arrival on site. Output can be up to 600 tonnes per hour, depending on materials being processed. The Warrior 1800 has compact transport dimensions and its power from a CAT engine and hydraulics are in proportion to the unit’s high performance. One of the most flexible screening machines on the market today, the Warrior 1800 has a highly aggressive screenbox which is able to operate with finger screens, woven mesh and punch plate on both top and bottom decks - the top deck can also operate with Bofor bar. Screen angle is hydraulically adjustable and the bottom deck options include a self-cleaning ball deck system with bottom screens easily accessible for changing or maintenance. The Warrior 1800 used at Cape Hatteras had a 75mm punch-plate top deck and a 60mm harp bottom deck.
The large hopper - with hydraulic folding Hardox steel sides and folding rear door to accommodate direct feed from a crusher - has a generous capacity and a variable speed incline feeder. Feeder is equipped with impact bars and discharges onto the screenbox from above in order to eliminate bridging.
All the stockpiling conveyors have a high capacity and are hydraulically folding and angle adjustable. The mid-size material falls directly on to the mid-product conveyor, and an oversize conveyor features a special adjustable system that allows easy access to the bottom deck meshes for cleaning, overhaul or replacement.
