Qalabka granulation bacriminta isku dhafan
Qalabka granulation bacriminta isku dhafan ayaa loo isticmaalaa soo saarista bacrimiyeyaasha isku dhafan.Bacriminta isku dhafan waa bacrimiyeyaasha ka kooban laba ama in ka badan oo nafaqo ah, sida caadiga ah nitrogen, fosfooraska, iyo potassium, oo ku jira hal badeeco.Qalabka granulation bacriminta isku dhafan ayaa loo isticmaalaa in alaabta ceeriin loo beddelo bacrimiyeyaasha isku jira granular kuwaas oo si fudud loo kaydin karo, loo rari karo, laguna dabaqi karo dalagyada.
Waxaa jira dhowr nooc oo ah qalabka granulation bacriminta isku dhafan, oo ay ku jiraan:
1.Drum granulators: Kuwani waxay isticmaalaan durbaan weyn oo wareeg ah si ay u abuuraan granules.Qalab cayriin ah ayaa lagu daraa durbaanka, iyo ficil-celinta durbaanka ayaa ka caawiya sameynta granules.
2.Duub rullaluistemadka extrusion granulators: Kuwani waxay isticmaalaan lammaane rollers si ay ugu cadaadinayaan alaabta ceeriin galay granules.Cadaadiska ka imanaya rollers wuxuu caawiyaa inuu abuuro granules isku dhafan, isku mid ah.
3.Disc granulators: Kuwani waxay isticmaalaan saxan wareeg ah si ay u abuuraan granules.Alaabta ceeriin ah ayaa lagu daraa saxanka, iyo xoogga centrifugal ee uu abuuray saxanka wareeggu wuxuu caawiyaa sameynta granules.
4.Spray granulators: Kuwani waxay isticmaalaan habka buufinta si ay u abuuraan granules.Qalabka ceeriin waxaa lagu buufiyaa dareeraha dareeraha ah, kaas oo ka caawiya sameynta granules.
Doorashada qalabka granulation bacriminta isku dhafan waxay ku xiran tahay baahida gaarka ah ee soo saaraha bacriminta, nooca iyo qadarka alaabta ceeriin ee la heli karo, iyo sifooyinka alaabta la rabo.Xulashada saxda ah iyo isticmaalka qalabka granulation bacriminta isku dhafan waxay gacan ka geysan kartaa hagaajinta waxtarka iyo waxtarka wax soo saarka bacriminta isku dhafan, taasoo horseedaysa wax-soo-saarka dalagga oo wanaagsan iyo hagaajinta caafimaadka ciidda.
