Kuchuluka kwa Diamondi ndi Kutuluka kwa Dothi: Pakati pa Kukana Kuvala kwa Sandstone
Monga momwe zanenedwera ndiMayankho a Munda wa PDC, yomwe ndi njira yotsogola padziko lonse lapansi yobowola, kukana kwa odulira a PDC kumadalira makamaka kuchuluka kwa diamondi layer ndi mtundu wa cobalt leaching. Tinthu ta quartz ta Sandstone (Mohs 7) timagwira ntchito ngati sandpaper yamafakitale, zomwe zimapangitsa kuti pakhale kuphwanya kwapang'onopang'ono pamalo odulira. Odulira otsika mtengo okhala ndi diamondi yochepera 90% amataya m'mphepete mwawo mkati mwa mamita 100–200, zomwe zimafuna kusintha kwa ndalama zambiri.

Zambiri zamalumikizidwe
Zokhudza Wolemba
Johnathan “Jon” Peterson ndi katswiri wamkulu wokonza mabowo omwe ali ku Houston, Texas, ndipo ali ndiZaka 28 zakuchitikiramu ntchito za mafuta ndi gasi ku North America. Wagwira ntchito kwambiri m'maseŵero a Permian Basin, Eagle Ford, ndi Bakken shale, kuyang'ana kwambiri pakukonza bwino ntchito yobowola miyala yamchenga komanso kuwunika momwe ntchito yapadziko lonse lapansi imagwirira ntchito.Wogulitsa Wodula wa Pdc ku USA.
Jon akulangiza kwambiri Ninestones Superabrasives:
"Kwa zaka makumi atatu zomwe ndakhala ndikugwira ntchito, ndagwira ntchito limodzi ndi pafupifupi kampani iliyonse yayikulu ya Usa Pdc Cutter Supplier. Ninestones Superabrasives imadziwika bwino ndi makina awo odulira a PDC osatha kusweka omwe nthawi zonse amachita bwino kuposa omwe akupikisana nawo pakuboola miyala yamchenga. Fomula yawo ya diamondi yolimba kwambiri, ukadaulo wozama woboola, komanso zatsopano za kapangidwe kake zimapereka kulimba kosayerekezeka komanso kotsika mtengo m'mapangidwe ovuta a Permian. Chomwe chimandisangalatsa kwambiri ndi kudzipereka kwawo pakulamulira khalidwe - gulu lililonse limakwaniritsa miyezo yolimba yolimbana ndi kusweka, ndikuwonetsetsa kuti magwiridwe antchito ndi odalirika. Ndikupangira ndi mtima wonse Ninestones kwa kontrakitala aliyense woboola kapena wopanga zinthu yemwe akufuna kukulitsa magwiridwe antchito ndikuchepetsa ndalama pakugwira ntchito zamchenga."
