Macdanta dhagaxa adag ee Buuraha Appalachian, badanaa waxaan fadhiyaa agteeda mashiinka caajiska ah ee tunnel-ka, anigoo daawanaya ilkaha jarista - ka dib 11 sano oo aan ahaa la-taliye goobta ah oo ku takhasusay qalabka macdanta ee Mareykanka, su'aasha ugu badan ee ay macdan qodayaashu isweydiiyaan waa: "Iliggee, Pyramid ama Conical PDC, ayaa yareyn doona waqtiga shaqada?" Toddobaadkii hore, macdan isku dhafan oo shale-granite ah oo ku taal Pennsylvania, ayaan rakibay.Gelinta Ahraamta PDCiyo Conical PDC Inserts oo ka socda Wuhan Ninestones Superabrasives Co., Ltd. isla mashiinkaas waxayna sameeyeen tijaabo hawlgal oo joogto ah oo 96 saacadood ah. Waxqabadka labada ilig ayaa si cad u qeexay doorashada miinooyinka Mareykanka.

Qaab-dhismeedka ayaa go'aaminaya: Mabda'a Jabinta Dhagaxa ee Wareega ah ee Gelinta PDC ee Ahraamta

"Awoodda shaqaynta" ee iliga PDC waxay gebi ahaanba ku jirtaa qaab-dhismeedkiisa. Qalabka PDC ee Conical, oo leh qaab-dhismeedkiisa koonka ee qaabka qubbada leh, ayaa kala firdhiya saameynta wuxuuna ku habboon yahay dhagaxa jilicsan ee isku midka ah. Si kastaba ha ahaatee,Gelinta Ahraamta PDC, oo leh qaabkeeda afar-geesoodka ah, waxay leedahay saddex meelood meel oo keliya aagga taabashada leh lakabka dhagaxa marka la barbar dhigo ilkaha koonka ah, taasoo si toos ah u labanlaabaysa cadaadiska marka la qaniinayo dhagaxa adag. Tijaabooyinka, granite oo leh cufnaan dhan 2.9 g/cm³,Gelinta Ahraamta PDCWaxay si dhakhso badan u jartaa 18% ilkaha koonka ah. Caaradda fiiqan ayaa sidoo kale ku dhegi karta dildilaacyo yaryar oo ku yaal lakabka dhagaxa, si ka duwan qubbada oo "simbiriirixata oo wareegta." Tani waa "fure jabinta dhagaxa" ee qaab-dhismeedka dhagaxa cufan sida kuwa gobolka Appalachian.

La qabsiga Loo Habeeyey ee Xaaladaha Macdanta: Faa'iidada Culayska Badan ee Gelinta Pyramid PDC

Qaybaha ku yaal meelaha macdanta laga qodo ee Mareykanka waligood ma aha "qaacido keliya" -- macdanta birta ee Montana, xididdada shale iyo quartz ayaa la isku daraa, taasoo u baahan in ilkaha la jarayo ay isku beddelaan qaniinyada lakab jilicsan iyo iska caabbinta walxaha adag. Tijaabooyinka, cidhifka fiiqan eeGelinta Ahraamta PDCsi sax ah ayuu u dhex galay lakabka xididka quartz isagoon jajabin ama jabin dhibco adag. Ka dib 6 saacadood oo hawlgal joogto ah, lakabka dheemanka ee Pyramid PDC Insert wuxuu muujiyay kaliya xirasho yar, halka ilkaha koonka ah ay horey u sameeyeen saddex jajab, taasoo u baahan xidhitaan iyo beddel. Meelaha macdanta laga qodo ee leh dabaqyo adag,Insert-ka Pyramid PDC"Adkeysi" si cad ayuu uga sarreeyaa u adkeysiga culaysyada sare.

 Falanqaynta Qiimaha Macdanta Mareykanka: Faa'iidooyinka Muddada Dheer ee Gelinta Pyramid PDC

Milkiilayaasha macdan qodista ee Mareykanka waxay mudnaanta siiyaan "falanqaynta waxtarka leh ee kharashka-faa'iidada": Macdan qodista dhuxusha ee Texas ayaa hore u baahnayd in ilkaha la jarayo la beddelo 8 jeer bishii marka la isticmaalayo ilkaha koonka ah, taasoo keentay in 350 tan oo dhuxul ah ay lumiyaan sababtoo ah waqtiga shaqada oo yaraada. Ka dib markii loo beddelay Pyramid PDC Inserts, celceliska tirada beddelka ilkaha bishiiba waxay hoos ugu dhacday 3, taasoo yareysay saacadaha shaqada ee lumay 65%. Marka la eego farqiga qiimaha halbeegga ee ilkaha, guud ahaan kharashka bishiiba wuxuu dhab ahaantii hoos u dhacay 25%. Tani waa faa'iidada "beddelka ilkaha oo yar, shaqo badan" - haddii macdan qodistaadu ay sidoo kale la halgameyso dhagax adag iyo lakabyo isku xiran, naqshadda fiiqan eeGelinta Ahraamta PDCwaxay kaa caawin kartaa inaad wax ka qabato caqabadahan adag.
