Onse awirigranulator yachitsulondipo chopalira mikanda ndi chinthu chomwecho, zonse zimagwiritsidwa ntchito popanga tinthu tamtengo wapatali ta chitsulo. Tinthu tating'onoting'ono timagwiritsidwa ntchito popanga zitsulo pokonza zinthu zophikidwa ndi alloy, zinthu zotulutsa nthunzi, kapena kafukufuku wa labotale ndi kupanga zinthu zatsopano. Tinthu tating'onoting'ono timeneti tinganenenso kuti tili ndi msika waukulu ku China.

Kawirikawiri pali mitundu iwiri ya zofalitsa zachitsulo chamtengo wapatali (granulators) pamsika, zomwe ndi zofalitsa za vacuum pressurized bead ndi zofalitsa wamba za mikanda. Mitundu yonse iwiri ya zofalitsa ndi yoyenera kupanga zitsulo monga golide, K-golide, siliva, mkuwa, ndi alloys. Koma opanga pamsika nthawi zambiri amasankha chofalitsa choyambirira cha vacuum pressure bead kuti apange njira. Chifukwa chiyani izi zili choncho?

Choyamba, poganizira za mfundo ya zida, ma granulator wamba amagwiritsa ntchito ma granulator otseka kapena odziyendetsa okha, kudalira mphamvu yokoka yachilengedwe kuti madzi achitsulo alowe mu thanki yamadzi kuti akaumbe. Kawirikawiri, tinthu tomwe timapangidwa si tozungulira mokwanira ndipo sitingakhale ofanana.

Chotsukira mpweya chopanda mpweya chimagwiritsa ntchito chitetezo cha mpweya wosagwira ntchito kuti chisungunule chitsulo, ndipo chikasungunuka, madzi achitsulo amathiridwa mu thanki yamadzi pansi pa kukakamizidwa kwa zipinda zapamwamba ndi zapansi. Mwanjira imeneyi, tinthu tachitsulo tomwe timapeza timakhala tofanana kwambiri ndipo timazungulira bwino.

Kachiwiri, chifukwa cha chitetezo cha mpweya wopanda mpweya, chotsukira mpweya chimapanga tinthu tating'onoting'ono pachitsulocho ndikuchotsa mpweya wonse. Chifukwa chake, pamwamba pa tinthu tating'onoting'ono timeneti ndi losalala, lopanda okosijeni kapena kuchepera, ndipo kuwala kwake kumakhala kwakukulu kwambiri.
