Onse awirizitsulo granulatorndipo choululira mikanda ndi chinthu chofanana, chomwe chimagwiritsidwa ntchito kupanga tinthu tating'ono ting'onoting'ono tachitsulo. Zitsulo zing'onozing'ono zimagwiritsidwa ntchito popanga zitsulo popanga alloy patching, zinthu zotulutsa mpweya, kapena kafukufuku wa labotale ndikupanga zida zatsopano. Zitsulo zazing'ono zitha kunenedwanso kuti zili ndi msika waukulu ku China.

Pamsika pali mitundu iwiri yazitsulo zamtengo wapatali zofalitsa mikanda (granulators) zomwe ndi vacuum pressurized mikanda zofalitsa ndi zofalitsa mikanda wamba. Mitundu yonse iwiri ya granulator ndi yoyenera kupanga zitsulo monga golide, K-golide, siliva, mkuwa, ndi ma aloyi. Koma opanga pamsika nthawi zambiri amasankha akale - vacuum pressure mikanda yofalitsa kuti apange njira. Chifukwa chiyani?

Choyamba, potengera mfundo za zida, ma granulator wamba amagwiritsa ntchito blockage kapena ma granulator odziyendetsa okha, kudalira mphamvu yokoka yachilengedwe kuti madzi achitsulo aziyenda mu thanki yamadzi kuti akawumbe. Nthawi zambiri, tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono ndipo sitingakhale ofanana.

Vacuum granulator imagwiritsa ntchito chitetezo cha gasi cha inert kuti isungunuke zitsulo, ndipo kusungunuka kutatha, madzi achitsulo amatsanuliridwa mu thanki yamadzi pansi pa kupanikizika kwa zipinda zapamwamba ndi zapansi. Mwanjira imeneyi, tinthu tachitsulo timapeza timafanana kwambiri komanso timazungulira bwino.

Kachiwiri, chifukwa cha kutetezedwa kwa mpweya wa inert, vacuum granulator imayendetsa tinthu tating'onoting'ono pazitsulo ndikulekanitsa mpweya. Choncho, pamwamba pa particles kuponyedwa ndi yosalala, popanda makutidwe ndi okosijeni kapena shrinkage, ndi glossiness ndi mkulu kwambiri.
