Ma granule a rabara akuda ndi tinthu tating'onoting'ono tozungulira topangidwa kuchokera ku zipangizo za rabara zobwezerezedwanso, makamaka zochokera ku matayala akale. Ma granule awa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kulimba kwawo, kusinthasintha, komanso kugwiritsa ntchito ndalama moyenera.

Mu makampani amasewera, tinthu ta rabara takuda ndi gawo lofunika kwambiri pakupanga minda ya udzu wopangidwa. Timapereka maziko olimba omwe amawonjezera kuyamwa kwa udzu ndi mphamvu zotetezera, kuchepetsa chiopsezo cha kuvulala kwa othamanga. Kuphatikiza apo, mtundu wakuda wa tinthu ta raba umathandiza kuyamwa kutentha, zomwe zingathandize kuti udzuwo usungunuke ndikuwonjezera moyo wake.

Kupatula masewera, tinthu ta raba takuda timagwiritsidwanso ntchito popanga malo osewerera, kuphimba malo, komanso ngati zinthu zopangira zinthu zatsopano za raba. Kutha kwawo kupirira kuwonongeka ndi kung'ambika kumawapangitsa kukhala chisankho chabwino kwambiri m'malo omwe anthu ambiri amakhala, monga misewu yoyendamo ndi misewu yolowera m'misewu.

Kuphatikiza apo, kugwiritsa ntchito raba wakuda kumathandiza kuti chilengedwe chikhale cholimba mwa kuchepetsa zinyalala ndikulimbikitsa kubwezeretsanso matayala akale. Izi sizimangoteteza zachilengedwe zokha komanso zimathandiza kuchepetsa kuwonongeka kwa matayala chifukwa cha kutaya matayala.
