Zombinii-granulator yesinyithikunye ne-bead spreader ziyimveliso efanayo, zombini ezisetyenziselwa ukuvelisa amasuntswana esinyithi axabisekileyo. Iintsimbi ezincinci ze-particle zihlala zisetyenziswa ekucubungulweni kwesinyithi xa kupeyintwa i-alloy, kwizixhobo zokufuma, okanye kuphando lwelabhoratri kunye nophuhliso lwezinto ezintsha. Iintsimbi ezincinci ze-particle zinokuthiwa zinemarike enkulu eTshayina.

Ngokwesiqhelo kukho iintlobo ezimbini zeentsimbi ezisasaza iintsimbi ezixabisekileyo (iigranulators) ezithengiswayo, ezizezi: iintsimbi ezisasaza iintsimbi ezicinezelweyo kunye neentsimbi eziqhelekileyo. Zombini ezi ntlobo zeegranulators zifanelekile ukwenza iintsimbi ezifana negolide, igolide ye-K, isilivere, ubhedu, kunye nee-alloys. Kodwa abavelisi abakwimarike badla ngokukhetha i-vacuum pressure bead spreader yangaphambili ukuze kwenziwe inkqubo. Kutheni kunjalo?

Okokuqala, ngokwembono yomgaqo wezixhobo, ii-granulators eziqhelekileyo zisebenzisa ii-blockage okanye ii-self flow granulators, zixhomekeke kubunzima bendalo ukwenza ulwelo lwesinyithi lungene kwitanki yamanzi ukuze lubumbeke. Ngokubanzi, amasuntswana aqulunqwe awanangqukuva ngokwaneleyo kwaye asenokungafani.

I-vacuum granulator isebenzisa ukhuseleko lwegesi olungasebenziyo ukunyibilikisa isinyithi, kwaye emva kokuba ukunyibilika kugqityiwe, ulwelo lwesinyithi lugalelwa kwitanki yamanzi phantsi koxinzelelo lwamagumbi aphezulu nasezantsi. Ngale ndlela, amasuntswana esinyithi esiwafumanayo afana ngakumbi kwaye anobungqukuva obungcono.

Okwesibini, ngenxa yokukhuselwa kwegesi engasebenziyo, i-vacuum granulator yenza i-particle casting kwisinyithi ngelixa ihlukanisa umoya ngokupheleleyo. Ke ngoko, umphezulu we-particles cast uthambile, awuna-oxidation okanye ukushwabana, kwaye ukukhazimla nako kuphezulu kakhulu.
