Pehea e koho ai i nā tricone drill bits no ka mining?
ʻO ka hoʻolālā onā ʻāpana triconepono e hoʻololi i nā ʻano o ka pōhaku e wili ʻia, a ua ʻae ʻia nā ʻano hoʻolālā like ʻole no ka ʻāpana cone roller i hoʻohana ʻia no nā ʻano pōhaku like ʻole. ʻO ka tricone drill bit i hoʻohana ʻia no ka wili pōhaku palupalu e hoʻohana pinepine i kahi kiʻekiʻe niho lōʻihi, a he liʻiliʻi ka manawa hoʻohele niho, i mea e maʻalahi ai ka ʻōwili ʻana a me ka ʻoki ʻana o ka drill bit ma ka ʻili pōhaku, i hiki ai ke hoʻokō i ke kumu o ka ʻohi pōhaku wikiwiki. No ka wili pōhaku paʻakikī, hoʻohana ʻia ka ʻili niho spherical kiʻekiʻe, paʻa nā niho, a ʻolokaʻi ʻia ka pōhaku i ka wā o ka wili ʻana, i mea e hōʻemi ai i ka sliding scraping e like me ka hiki. I mea e hōʻemi ai i ka ʻaʻahu ʻana o ka pōhaku ma luna o ka huila, hoʻohana mau ʻia nā niho huila i ka bit cone roller.
