Te mahi a teYT28He māmā noa iho, he whai hua hoki te keri toka hau: tuatahi, honoa ki tētahi pūtake hau kōpeke mā te whakamahi i tētahi paipa hau 25mm me tētahi paipa wai 13mm hei pehi i te puehu; kātahi, tāpirihia ki tētahi mata keri 34-42mm me tētahi kakau keri hexagonal 22×108±1mm, whakatikatikahia te pēhanga mahi ki te awhe o te 0.5-0.6MPa, kātahi ka tīmata te keri mā te kakau whakahaere whakauru. Ka taea te whakauru ki tētahi waewae hau poto FT160BD, ki tētahi waewae hau roa FT160BC rānei hei keri i ngā kōhao whakapae me ngā kōhao whakarara, ā, ka taea hoki te tāuta ki runga i ngā taraka mō ngā mahi hanga nui, ka taea ai e tētahi kaiwhakahaere kotahi te whakaoti i ngā mahi keri me te whai hua.

Ki te whakataurite ki ngā keri kohatu noa i whakamahia i mua i roto i ngā mahi keri, ko teYT28 wiri toka waewae hauHe tino painga ngā keri toka tuku iho. Ka whakawhirinaki ngā keri toka tuku iho ki te kaha ā-ringa, e hiahia ana ki te kaha tinana nui mai i ngā kaiwhakahaere; heoi anō, ka tino heke te tere o te keri i te mea ka ngenge ngā kaiwhakahaere, me te tere keri toharite o te 30-40mm/min anake. He rerekē, ko te keri toka hau YT28 he auau pānga kāore i raro iho i te 34Hz me te kaha pānga neke atu i te 75J, ka taea te whakapai ake i te pai o te keri mā te 60%-80%—ko tōna tere keri toharite ka eke ki te 70-90mm/min, ā, ka taea e ia te keri poka tae atu ki te 5 mita te hohonu, ā, ka tino whakapoto i te huringa hanga. Hei tāpiri, ka puta he haruru nui (tae atu ki te 130dB) i ngā keri toka tuku iho, ā, he ngoikore te pumau, he maha ngā wā ka mutu te hanga nā te kino o ngā wāhanga. Heoi, kei te YT28 he taputapu ārai haruru e whakaiti ana i te haruru ki te taumata haumaru, ā, ko tana mahi pumau ka whakarite kia kore e mutu te hanga, ka whakapai ake i te haere tonu o te hanga.

Ko te whiriwhiri i te Kamupene Hau Shenli Machinery he tohu i te whiriwhiri i te pono, te whai huatanga me te tautoko ngaio. He rerekē ki ētahi atu kaihanga, he pūnaha tirotiro kounga whānui tā mātou; mai i te whiriwhiri i ngā rauemi mata ki te tuku i ngā hua kua oti, ka whakamatautauria ia hononga kia tino rite te kounga me te pumau o te mahi hua. He kaha te whānuitanga o ngā taputapu me ngā utu tiaki iti o te keri toka hau YT28. Hei tāpiri, ka whakaratohia e mātou he ratonga muri-hoko wā me te aratohu hangarau ngaio hei whakatau pai i ngā raruraru e pā ana ki ngā kiritaki i te wā e whakamahia ana te hua. Ehara i te mea ka whakapai ake te YT28 i te whai huatanga o te keri mā te 60%-80% engari ka whakaitihia hoki te kaha o te mahi, ka penapena pūngao (me te whakamahinga hau ≤55L/s) me te whakaiti i ngā utu hanga katoa. He whānui te whakamahinga i roto i te keri maina, te keri kauhanga me ētahi atu kaupapa hanganga, kua waiho hei whiringa pai mō ngā rōpū hangarau e whai ana i te whai huatanga teitei, te haumaru me te whai huatanga utu.
