Amakuru

Byombiicyumakandi gukwirakwiza amasaro nibicuruzwa bimwe, byombi bikoreshwa mugukora ibyuma byagaciro. Ibyuma bito bito bikoreshwa muburyo bwo gutunganya ibyuma, ibishishwa, cyangwa ubushakashatsi bwa laboratoire no guteza imbere ibikoresho bishya. Uduce duto duto dushobora nanone kuvugwa ko dufite isoko rinini mubushinwa.

Muri rusange hari ubwoko bubiri bwicyuma gikwirakwiza amasaro (granulators) kumasoko, aribyo gukwirakwiza vacuum igitutu cyamasaro hamwe nogukwirakwiza amasaro asanzwe. Ubwoko bwombi bwa granulator bukwiranye no gukora ibyuma nka zahabu, K-zahabu, ifeza, umuringa, hamwe na alloys. Ariko ababikora kumasoko mubisanzwe bahitamo icyambere - vacuum pression yamashanyarazi kugirango ikorwe. Kuki ibi?

Ubwa mbere, ukurikije ihame ryibikoresho, granulator zisanzwe zikoresha inzitizi cyangwa ubwikorezi bwa granulator, zishingiye kuburemere bwa kamere kugirango amazi yicyuma atembera mumazi yamazi kugirango abumbabumbe. Mubisanzwe, ibice byatewe ntibizengurutse bihagije kandi ntibishobora kuba bimwe.

Imashini ya vacuum ikoresha kurinda gazi ya inert kugirango ishonge ibyuma, hanyuma nyuma yo gushonga birangiye, amazi yicyuma asukwa mumazi yamazi munsi yigitutu cyibyumba byo hejuru no hepfo. Muri ubu buryo, ibice by'icyuma tubona birasa kandi bifite uburinganire bwiza.

Icya kabiri, kubera kurinda gaze ya inert, granulator ya vacuum ikora uduce duto duto ku cyuma mugihe gitandukanya umwuka rwose. Kubwibyo, ubuso bwibice byajugunywe biroroshye, nta okiside cyangwa kugabanuka, kandi ububengerane nabwo buri hejuru cyane
