SCREENING Old meets new A pair of crushers are repositioned with a heavy duty screen in a custom fabrication job thats providing productivity and portability K eith Hagedorn had a unique set of characteristics in mind as he pursued a new screen for his contract crushing company last winter Hagedorn wanted a heavy duty screen that could handle as many tons of rock as possible He also wanted a screen that offered the ability to start and finish jobs faster The desire for these screening characteristics ultimately drove Hagedorn to MAB Equipments Mark Blanchflower who introduced Hagedorn and his two sons to a potential option My son and I were looking on the Internet and he found that the Deister Machine Co screener was a lot more heavy duty built says Hagedorn owner of Keith Hagedorn Construction in Spirit Lake Iowa Something that will last a long time is important to me Theres always a fine line between portable equipment and heavy duty but the Deister screen was heavier duty than everything Screen capacity was an important factor for Hagedorn Construction as well The companys former plant included a 5 ft x 14 ft two deck screen along with a duplex Terex Cedarapids Commander 556 that featured a 12 in x 36 in jaw crusher and a 30 in x 30 in twin roll crusher According to Hagedorn the 5 ft x 14 ft screens capacity was no longer practical for the companys needs Hagedorn asked whats the largest screen we could put on a portable chassis Blanchflower says He chose the 8 ft x 20 ft triple deck screen that also has a triple shaft mechanism Hagedorns particular model Deisters TFM3P 3820 also offers Hagedorn Construction the flexibility it sought in a new screen We had a 3 degree slope put on it to get material to move faster Hagedorn says Originally we were going to go with a horizontal The screen chassis has a sand discharge reject conveyor available We dont have it in there now but its something we can slip in there to take out 3 8 in minus fines The sand discharge conveyor is a nice option to have Hagedorn says I make a lot of road gravel and some of it has an excessive amount of sand he says Some counties are interested in taking the sand out so they have better quality gravel and they get another product in deicing sand One of Hagedorns sons Brandon adds that the 3 degree slope is useful in combatting sticky material that would otherwise slow material flow rate All of our material has clay bound to the BY KEVIN YANIK TCI Manufacturing custom fabricated Keith Hagedorn Constructions plant which features an 8 ft x 20 ft triple deck screen from Deister Machine Co 16 PIT QUARRY July 2015 www pitandquarry com
