Alumina chena yakasanganiswauye alumina yakasanganiswa nebrown imhando mbiri dzinoshandiswa zvakanyanya. Vanhu vazhinji havazivi musiyano wakananga pakati pezviviri izvi kunze kweruvara. Iye zvino ndichakuudza kuti unzwisise.
Kunyangwe hazvo ma abrasives ese ari maviri aine alumina, huwandu hwe alumina mu alumina chena yakasanganiswa hunopfuura 99%, uye huwandu hwe alumina mu alumina yakasanganiswa yebrown hunopfuura 95%.
Alumina chena yakasanganiswainogadzirwa kubva muupfu hwealumina, nepo alumina yakasanganiswa yebrown ine anthracite nesimbi, pamwe ne calcined bauxite. Alumina chena yakasanganiswa ine kuomarara kwakanyanya inoshandiswa nevamwe vashandisi vepamusoro, nekuti ine simba rekucheka riri nani uye inopenya zvakanaka, uye inonyanya kushandiswa pakugadzira simbi yekabhoni, simbi ye alloy, simbi yakagadzirwa, bronze yakaoma, nezvimwewo. Shandisa alumina chena yakasanganiswa kuti unyatsokuya zvakanaka uye zvakajeka,
Alumina yakasanganiswa nebrown inoshandiswa mumusika wakakura, uye inonyanya kushandiswa pakugadzira simbi yakadzima, simbi inomhanya zvikuru, uye simbi ine kabhoni yakawanda kubvisa maburi pamusoro, uye mhedzisiro yekukuya haina kupenya seye alumina chena yakasanganiswa.
