Tlhokahalo ea lebelo la Rotary
Boiphihlelo bo bontšitse hore tlas'a maemo a joalo hore li-cuttings li ka tlosoa hantle ho tloha ka sekoting, RPM e na le kamano e haufi-ufi le tekanyo ea ho kenella ka har'a mefuta e itseng.Ha RPM e ntse e eketseha, sekhahla sa ho kenella se tla eketseha mabapi le litšobotsi tsa sebopeho.
Litlhoko tsa Moea
Moea o hatelitsoeng o sebelisoa haholo bakeng sa ho phethola li-cuttings ho rotary blast hold rig ea ho cheka.E sebeletsa mesebetsi e 'meli ea bohlokoa;E 'ngoe ke
