Ko ngā pereki konumohe-teitei mō ngā oumu pupuhi he mea hanga ki te bauxite kounga teitei hei rauemi mata matua, ka purangahia, ka pēhia, ka whakamarokehia, ka tahuna ki te pāmahana teitei. He hua ātete ahi ēnei e whakamahia ana hei whakapuru i ngā oumu pupuhi.
1. Ngā tohu ā-tinana me te matū o ngā pereki alumina teitei
| TAUPAPA | SK-35 | SK-36 | SK-37 | SK-38 | SK-39 | SK-40 |
| Te ātete (℃) ≥ | 1770 | 1790 | 1820 | 1850 | 1880 | 1920 |
| Te Matotoru o te Papatipu (g/cm3) ≥ | 2.25 | 2.30 | 2.35 | 2.40 | 2.45 | 2.55 |
| Te Āhua o te Porosity (%) ≤ | 23 | 23 | 22 | 22 | 21 | 20 |
| Kaha Pakaru Matao (MPa) ≥ | 40 | 45 | 50 | 55 | 60 | 70 |
| Huringa Raina Tuturu@1400°×2h(%) | ±0.3 | ±0.3 | ±0.3 | ±0.3 | ±0.2 | ±0.2 |
| Te Ātete i raro i te Utaina @ 0.2MPa(℃) ≥ | 1420 | 1450 | 1480 | 1520 | 1550 | 1600 |
| Al2O3(%) ≥ | 48 | 55 | 62 | 70 | 75 | 80 |

2. Kei hea ngā pereki konumohe teitei e whakamahia ana i roto i ngā oumu pupuhi?
Ka hangaia ngā pereki konumohe-teitei ki runga i te pou oumu o te oumu pupuhi. Kei te wāhanga o runga o te oumu pupuhi te pou oumu. Ka whānui haere tōna whānui mai i runga ki raro kia urutau ki te whānui wera o te utu me te whakaiti i te waku o te pakitara oumu i runga i te utu. Ka noho te tinana oumu i roto i te oumu pupuhi. 50%-60% o te teitei whai hua. I roto i tēnei taiao, me tutuki i te arai oumu ēnei whakaritenga, ā, ko ngā āhuatanga o ngā pereki konumohe-teitei ko te ātete nui, te pāmahana ngawari teitei i raro i te kawenga, te ātete waikawa, te ātete kawakore, te ātete kaha ki te horo o te para, me te ātete pai ki te kakahu. Ka taea te whakatutuki, nō reira he tino pai mō te tinana oumu pupuhi kia arai ki ngā pereki konumohe-teitei.
He kupu whakataki tēnei mō ngā pereki alumina teitei mō ngā oumu pupuhi. He uaua te taiao whakarārangi o te oumu pupuhi, ā, he maha ngā momo rauemi ātete ahi e whakamahia ana. Ko ngā pereki alumina teitei tētahi o aua mea. E 3-5 ngā whakatakotoranga o ngā pereki alumina teitei e whakamahia ana. Ka taea te whakamahi i ngā pereki alumina teitei a Robert i roto i ngā momo oumu. Mena e tika ana, whakapā mai ki a mātou.
