Zombini iigranulator yesinyithikunye ne-bead spreader ziyimveliso efanayo, zombini zisetyenziselwa ukuvelisa amasuntswana esinyithi axabisekileyo. Amasuntswana amasuntswana esinyithi asetyenziswa ngokubanzi ekusetyenzweni kwesinyithi kwi-alloy patching, imathiriyeli ephumayo, okanye uphando lwebhubhoratri kunye nophuhliso lwemathiriyeli emitsha. Amasuntswana amasuntswana esinyithi nawo anokuthiwa anentengiso enkulu eTshayina.

Kukho ngokubanzi iindidi ezimbini zeentsimbi ezixabisekileyo zentsimbi (igranulators) kwimarike, ezizezi, ivacuum pressurized bead spreaders kunye nesiqhelo sokusasaza amaso. Zombini iintlobo zegranulator zifanelekile ukwenza isinyithi njengegolide, i-K-igolide, isilivere, ubhedu, kunye nealloys. Kodwa abavelisi kwimarike bahlala bekhetha eyangaphambili - i-vacuum pressure bead spreader yenkqubo yokuvelisa. Kutheni kunje?

Okokuqala, ngokwembono yomgaqo-siseko wesixhobo, iigranulator eziqhelekileyo zisebenzisa i-blockage okanye i-self flow granulators, zixhomekeke kumxhuzulane wendalo ukwenza ulwelo lwentsimbi lungene kwitanki yamanzi ukuze lubunjwe. Ngokuqhelekileyo, iinqununu eziphonsiweyo azijikelezi ngokwaneleyo kwaye zingenakufana.

I-vacuum granulator isebenzisa ukukhuselwa kwegesi ye-inert ukunyibilikisa isinyithi, kwaye emva kokuba ukunyibilika kugqityiwe, i-metal liquid igalelwa kwitanki yamanzi phantsi koxinzelelo lwamagumbi aphezulu nangaphantsi. Ngale ndlela, amasuntswana esinyithi esiwafumanayo ayafana kwaye anoburharha obungcono.

Okwesibini, ngenxa yokukhuselwa kwegesi ye-inert, i-vacuum granulator iqhuba i-particle cast kwintsimbi ngelixa ihlukanisa ngokupheleleyo umoya. Ke ngoko, umphezulu wamasuntswana ophoswe agudileyo, ngaphandle kwe-oxidation okanye i-shrinkage, kwaye ukucwebezela kuphezulu kakhulu.
