A track-mounted horizontal impact crushing plantdelivers speed and specification on a majorDallas demolition andrecycle project.CrushingScoresMaximum ImpactThe Dallas Reunion Arena is no more. Recently, A&RDemolition oversaw a controlled drop of its roof, the laststep in the massive demolition of this 300,000-squarefootbuilding, which once seated more than 20,000 fans ofthe Dallas Mavericks. At least 75 percent of the structure wastargeted for recycle as officials initially determined that thecity could offset about $2.5 million of the nearly $6 milliondemolition cost by recycling and reusing remnants of the28-year-old stadium. Recognized for its turnkey approach,A&R Demolition won the bid from start to finish. The companywas established in 1992 by Raymond and Andrea Reveileand remains family-owned and operated. A&R prides itself onbeing “green” for more than 16 years, with 80 percent of itsmaterials being recycled by weight, much of it processed onthe jobsite or at its own concrete, wood, and metal recyclinglocation.Jim Rawson, Dallas division manager for A&R Demolition,says that an approximate 11,000 cubic yards of concrete inReunion Arena was crushed and reused on-site. There was a30-foot-deep hole to fill where the basketball floor sat atopthe hockey ice-rink below. The recycled material was used asa base for the fill dirt, which would bring the site to grade forfuture development.BRIDGING THE PRODUCTION GAPIn the midst of the major portion of the concrete recycle, theA&R team realized it needed to bring in a “pinch hitter” ofsorts to meet specification and production capacity goals. Thecompany maintained portable jaw crushers in its fleet, butfound that the units could not efficiently process the requiredtonnage at the desired specification. A&R consulted withCharlie Hayes, a sales engineer with T-K-O Equipment Co.,the Grand Prairie, Texas-based dealer for KPI-JCI. Since 1978,T-K-O has developed into one of the region’s leading firmsin the rental, lease, and sales of crushing equipment. Hayesrecommended the rental of a KPI-JCI FT4250 track-mountedhorizontal impact crushing plant specifically designed for therecycling of concrete and asphalt. This highly-mobile plantcombines a crusher and a screen in a true closed-circuitconfiguration, which is able to produce a final product in onepass from its single chassis.A&R decided to rent the plant to bridge a big gap inproduction. They were processing as they were demolishingwith the use of a multi-processor mounted on an excavator,which would process material from 6-foot slabs down to2-foot-minus chunks. Upon the creation of a stockpile that soondominated the limited footprint, the mobile crusher was brought20 volume 3, number 1 | Today’s aggregate & mining solutions
in. Rawson says that T-K-O providedexpedient delivery of the plant, droveit onto the site on its tracks, and it wasready to run when needed.MATERIAL IN ONE PASS“The plant achieved everything itneeded it to do. First, we needed acertain amount of tonnage—and theunit processed a total of 20,000 tonsin the several weeks that we ran it.It also provided a screen to size tothe specification required by the city(1.5-inch-minus grade six). It’s a dirtymaterial but it still has to go down toan inch and a half,” says Rawson,stressing that he couldn’t have gottenthat specification from their portablejaw crushers. “With the jaws andwithout a screen, we would havedoubled the process. With the FT4250,we could make the material in onepass. But ultimately it is the all-in-oneaspect of the plant—the impactor andscreen combination—that really sold uson the plant,” he says, adding that hehad operated impact crushers beforebut had not encountered anything likethis particular unit. “It was very userfriendlyand easy to operate. We couldcontrol all operations remotely from thecab of the excavator.”The FT4250 has a 42-inch by 50-inchfeed opening, which is large enoughso that material prep is minimized.Rawson says that the unit’s cross-beltmagnet system was very effective inpulling out large amounts of steel,which would be recovered and sold.The plant is engineered to withstandmetal contaminants without incident,and is equipped with a standardoverload protection system.“Bottom line, we rented the mobileplant because we needed fasterproduction—and the unit allowedus to stay to stay on schedule,” saysRawson, who estimates that the FT4250allowed them to save up to a month ofproduction time. “It also delivered amajor savings in labor and equipment.The alternative would have been usingthree or four different machines to dothe same thing but in twice the amountof time. We will definitely use this plantagain,” he says. Additionally, Rawsonexplains that the cost-effectiveness ofusing the FT4250 to process materialon-site is a huge advantage versusthe cost of hauling material to anotherprocessing location or outsourcing thecrushing to another source.GROWING MARKETKPI-JCI says that there is much growthin the recycle market for its Fast Trax(FT) line of track-mounted plants.Contractors can haul a track-mountedmachine on a flatbed, just as theywould an excavator, back it off thetrailer and in mere minutes, they arecrushing material. It makes it possibleto cost-efficiently process volumes aslow as 5,000 to 10,000 tons. Thatis in stark contrast to the days whenon-site crushing demanded projectsof 50,000 tons and up—and the onlyoption was a machine on a traditionalchassis—which meant lifting timbersand cribbing, a task that is timeconsuming and not without hazard.A&R Demolition says that it is alwayslooking for new ways to recyclematerials at its sites. And, even in aneconomic downturn, A&R is still findingmany bidding opportunities for militaryand school projects, markets whichhave remained active in Texas. OwnerRaymond Reveile reports that hiscompany is continuing to assess newequipment with upgraded technologies,such as the FT4250, in order toposition itself as leaders in a changingenvironment. He says that it allows thecompany to remain on budget, on time,and delivers an ability to do a job rightthe first time. That, he feels, is whatdifferentiates A&R in the demolitionand recycle marketplace. ■MOBILE STAR UPGRADE NOWSTANDARD ON KPI-JCI TRACKMOUNTED IMPACTOR PLANTSKPI-JCI’s Track Mounted Impactor Plantsare now equipped with the Mobile Starequipment monitoring system as astandard feature.Mobile Star delivers remote monitoringof Fast Trax equipment locations andoperation events. The system allows anycomputer with an internet connectionthe ability to access any machine that iscompatible with the Mobile Star controlsystem. Once installed, Mobile Star willmonitor all the equipment’s specificoperational parameters including anyengine information, hydraulic pressures,and GPS position. It also has the abilityto send customizable e-mail notificationsof operational events and logs thoseevents for future reference and troubleshooting.The Mobile Star system is scalable tomeet the needs of anyone from a singleunit owner to a dealer/rental fleetmanager and is retrofittable to all FastTrax units with a digsy control system.For more information on KPI-JCI TrackMounted Impactor plants, visit www.kpijci.com/track-mount/impactor-tracks.Wantmore?Contact Product Manager, Crushing/Screening and Tracks, Ron Griess at 605.668.2510,e-mail rongriess@kpijci.com, or visit www.kpijci.com.Today’s aggregate & mining solutions | volume 3, number 1 21
