Qalabka granulation bacriminta digada idaha
Digada idaha sidoo kale waxaa lagu farsamayn karaa bacriminta iyadoo la isticmaalayo qalabka granulation.Habka granulation waxaa ku jira in digada idaha lagu qaso maaddooyinka kale ka dibna u qaabeeya isku dar ah pellets yar yar ama granules kuwaas oo ay fududahay in la xakameeyo, kaydiyo, iyo gaadiidka.
Waxaa jira dhowr nooc oo qalabka granulation ah oo loo isticmaali karo soosaarka bacriminta digada idaha, oo ay ku jiraan:
1. Rotary granulator: Tani waa doorasho caan ah oo lagu soo saaro tiro badan oo ah pellets bacriminta digada idaha.Nidaamku wuxuu ku lug leeyahay in lagu daro binder digada idaha iyo maaddooyinka kale ka dibna lagu rido isku dar ah durbaanka wareegaya.Kulaylka uu dhaliyo durbaanka wuxuu caawiyaa inuu isku dhufto pellets.
2.Disc granulator: Noocan granulator-ku wuxuu isticmaalaa saxan wareeg ah si uu u dajiyo digada idaha iyo walxaha kale ee pellets.Saxanku waxa uu leeyahay baalooyin xagal xidhiidhsan oo ka caawinaya in la isku qaso maaddooyinka oo u qaabeeyaan pellets wareegsan.
3.Pan granulator: Si la mid ah granulator-ka saxanka, granulator-ka digsiga wuxuu isticmaalaa digsi wareeg ah si uu u darso digada idaha iyo walxaha kale ee pellets.Digsigu waxa uu leeyahay baalooyin xagal xidhiidhsan oo ka caawinaya in la isku qaso maaddooyinka oo u qaabeeyaan pellets wareegsan.
4.Granulator Extrusion: Noocan granulator-ku waxa uu isticmaalaa biraha birta ah si uu ugu qasbo digada idaha iyo walxaha kale iyada oo loo marayo dhinta si ay u abuuraan pellets.Soosaaruhu waxa uu cadaadis saarayaa isku dhafka, kaas oo ka caawinaya in ay u qaabeeyaan pellets.
5.Roller press granulator: Noocan granulator-ku wuxuu isticmaalaa laba rogo si uu digada idaha iyo walxaha kale ugu cadaadiyo pellets.Cadaadiska ay abuuraan rollers-ku wuxuu caawiyaa in ay isku dhafka u qaabeeyaan pellets.
Ka dib markii digada idaha lagu farsameeyo pellets, waxaa lagu sii daweyn karaa qalajinta, qaboojinta, dahaarka, iyo qalabyada kale si loo abuuro bacriminta tayada sare leh.
