Tricone bit inoshandiswa zvakanyanya kuchera rotary, inonyanya kushandiswa kuchera makomba mahombe uye makomba ekugadzira mumakori mahombe, migodhi yegomba rakavhurika, kuchera peturu, nemimwe minda.Kune mapoka maviri ekuboora mahombe anotenderedzwa: (1) kudzvanya kwechitenderedzwa nepamusoro-soro kurodha kudombo kubva kumakoni matatu, uye (2) kucheka kwechitenderedzwa neshear simba kubva pazvimedu zvinokweva.
Pakupwanya kutenderedzwa, mabhiti anoshandiswa zvakanyanya ndeatatu-makoni ekubooresa akavharwa nemazino mazhinji kana mabhatani anotenderera akasununguka segiya repuraneti uye anopwanya dombo apo chibooreso chinotenderedzwa.Kudzika kwakadzika kunowanikwa nehuremu hwechigadziro chekugadzirisa pachayo, uye kutenderera kunoshandiswa pamagumo epombi yekuchera.Kutenderera kunopiwa ne hydraulic kana motokari yemagetsi, uye kutenderera kunowanzosiyana kubva pa50 kusvika ku120 rpm.Mhepo yakamanikidzwa inowanzoshandiswa kuburitsa cuttings kubva pasi pegomba.Hukuru hwepakakoromoka pakati pepombi yekuboorera uye madziro egomba zvine chekuita nekutsvaira kwekucheka kwekucheka.Pamwe pakamanikana zvakanyanya kana kuti mukaha wakapamhama unodzikisira kumhanya kwekuchera.
Rotary drilling inokodzera hukuru hwechibhorani kubva pa203 kusvika 445 mm mudhayamita.Kusvika pari zvino, kuchera nematenderedzwa ndiyo yave nzira huru mumigodhi mikuru yakavhurika.Chimwe chezvakaipira ma rotary drilling rigs ndechekuti haakodzeri kuchera chibhorani chakarerekera, chinobatsira kuputika kwedombo.
Tricone percussion sando ichawedzera zvakanyanya kubereka, kunyanya mumamiriro ezvinhu akaomarara.Tinodada nekutaura kuti BD DRILL inokwanisa kupa ese anotenderera tambo yekuchera, kubva kuShock absorb, Drill pipe, Stabilizer, Percussion sando, Deck bush, Tricone bit.
