Tignoolajiyada ka saarista hadhuudhka graphite
Tignoolajiyada garaafyada hadhuudhka ee shaxanka waxa ay ku lug leedahay habka loogu beddelo miraha garaafka garaafyada pellets is haysta iyo isku mid ah.Farsamadaan sida caadiga ah waxaa ku jira dhowr tillaabo si loo gaaro qaabka pellet-ka ee la doonayo.Halkan waxaa ah dulmar guud oo ku saabsan tignoolajiyada graphite pelletizing grain:
1. Diyaarinta Graphite Grain: Tallaabada ugu horreysa waa in la diyaariyo miraha garaafka iyadoo la hubinayo inay yihiin cabbir iyo tayada ku habboon.Tani waxay ku lug yeelan kartaa shiidi, burburin, ama shiididda qaybaha garaafka waaweyn ee miraha yar yar.
2. Isku darka/Waxyaabaha lagu daro: Xaaladaha qaarkood, waxyaabaha lagu daro ama walxaha xidha ayaa laga yaabaa in lagu daro hadhuudhka garaafka si loo hagaajiyo samaynta pellet iyo xasiloonida.Waxyaalahan lagu daro waxay kor u qaadi karaan isku-xidhnaanta iyo xoogga pellets inta lagu jiro habka pelleting.
3. Habka Pelletizing: Waxaa jira farsamooyin kala duwan oo loo isticmaalo pelleting hadhuudhka garaafyada.Laba hab oo caadi ah waa:
a.Cadaadiska Pelletizing: Habkani waxa uu ku lug leeyahay in cadaadis lagu saaro miraha garaafka iyadoo la isticmaalayo mishiinka pelletizing ama saxaafadda.Cadaadisku wuxuu isku dhejiyaa miraha, taasoo keenaysa inay u hoggaansamaan oo ay sameeyaan pellets qaabka iyo cabbirka la rabo.
b.Pelletizing Extrusion: Extrusion waxay ku lug leedahay qasbi isku dhafka hadhuudhka garaafka iyada oo loo marayo dhinta ama caaryada hoos yimaada cadaadis sare.Habkani waxa uu u qaabeeyaa miraha graphite oo u noqda xadhig joogto ah ama pellets marka ay dhex maraan dhinta.
4. Qalajinta iyo Daawaynta: Ka dib samaynta pellet, garaafyada garaafyada waxaa laga yaabaa inay maraan habka qalajinta iyo daaweynta si looga saaro qoyaanka dheeraadka ah oo kor loogu qaado xooggooda iyo xasilloonida.Talaabadani waxay hubinaysaa in pellets-ku ay yihiin kuwo waara oo ku habboon habayn dheeri ah ama codsiyo.
5. Xakamaynta tayada: Inta lagu jiro habka pelletizing, tallaabooyinka xakamaynta tayada ayaa lafuliyaa si loo hubiyo in garaafyada garaafka ugu dambeeya ay buuxiyaan shuruudaha la rabo.Tan waxaa ku jiri kara tijaabinta cabbirka, cufnaanta, xoogga, iyo cabbirrada kale ee khuseeya.
Tignoolajiyada hadhuudhka graphite way kala duwanaan kartaa iyadoo ku xidhan shuruudaha iyo codsiyada gaarka ah.Doorashada qalabka iyo cabirrada habka waxay ku xirnaan doontaa arrimo ay ka mid yihiin cabbirka pellet, awoodda wax soo saarka, sifooyinka pellet ee la rabo, iyo tixgelinta qiimaha.Tignoolajiyada horumarsan, sida pelletization-ka aan xidhnayn, ayaa sidoo kale laga yaabaa in la isticmaalo si loo baabi'iyo baahida loo qabo walxaha isku xidhan ee habka pelletizing.
Waxaa muhiim ah in la ogaado in dhinacyada farsamada ee tifaftiran ee tignoolajiyada hadhuudhka garaafyada ay u baahan karaan cilmi baaris dheeraad ah ama la tashi lala yeelanayo khubarada goobta ku sugan si si buuxda loo fahmo oo loo hirgeliyo habka si wax ku ool ah.
