Ko te hama te wāhanga mahi tino nui, tino ngāwari hoki te pakaru o te kuru

I tēnei wā, he maha ngā āhua o te hama e whakamahia ana, engari ko te mea e whakamahia whānuitia ana ko te hama tapawhā rite ki te pereti. Nā te mea he māmā te āhua, he ngāwari te hanga, ā, he pai hoki te whakamahi.

E rua ngā toki titi o te tauira whaipainga, ko tētahi he kōhao raupapa kei te toki titi, ka taea te huri hei mahi mā ngā kokonga e whā. Ka pania te taha mahi ki te tungsten carbide, ka whakapirihia rānei ki tētahi koranu ātete-kakahu motuhake hei whakaroa i te roa o te mahi.

Heoi, he nui te utu hanga. Ka hangaia ngā kokonga e whā hei trapezoid, hei kokonga me hei kokonga koi hei whakapai ake i te pānga kuru ki te whāngai muka kai, engari he ngoikore te ātete ki te kakahu. Kotahi anake te kōhao titi o te hama porowhita, ā, ka huri aunoa te koki mahi i te wā e whakamahia ana, nō reira he ōrite te kakahu, he roa te ora ratonga, engari he uaua te hanganga.

He pereti maitai te hama tapawhā maitai whakakotahi, he tino mārō ki ngā mata e rua, ā, he pakari hoki ki waenganui, nā te mira hurihuri i whakarato. He māmā te hanga, he iti hoki te utu.

E whakaatu ana te whakamātautau he pai te hama me te roa tika hei whakanui ake i te putanga mana o te kilowatt-haora, engari ki te roa rawa, ka piki ake te whakamahinga o te konganuku, ā, ka heke iho te putanga mana o te kilowatt-haora.

Hei tāpiritanga, e ai ki te whakamātautau kuru kānga i whakahaerehia e te China Academy of Agricultural Mechanization me ngā hama 1.6mm, 3.0mm, 5.0mm me te 6.25mm, ko te pānga kuru o ngā hama 1.6mm he 45% teitei ake i ngā hama 6.25mm, ā, he 25.4% teitei ake i ngā hama 5mm.

He tino pai te kuru o te hama angiangi, engari he poto noa te roa o tōna mahi. Me rerekē te matotoru o ngā hama e whakamahia ana i runga i te rahi o te mea kuru me te tauira. Kua whakapūmautia te hama o te huri whāngai i Haina. Kua whakatauhia e te Manatū Ahumahi Mīhini e toru ngā momo hama paerewa (momo I, II me te III) (hama tapawhā rua).
