Warshadda shiididda dhagaxa Raymond waxay door muhiim ah ka ciyaartaa diyaarinta budada dhagaxa nuuradda ee la qalajiyey. Tayada warshadda shiididda dhagaxa Raymond waxay si toos ah u saamaysaa tayada, quruxda iyo qaybinta cabbirka walxaha ee budada dhagaxa nuuradda. Kuwa soo socdaa waxay sharxi doonaan astaamaha farsamo iyo codsiyada gaarka ah ee warshadda shiididda dhagaxa Raymond ee shiididda dhagaxa nuuradda.

1. Muhiimadda weyn ee loo adeegsado warshadda dhagaxa Raymond ee nadiifinta budada dhagaxa nuuradda

Shalay, Shirweynihii ugu horreeyay ee Shir-madaxeedka Kaarboon-ka ee Xisaabta Shiinaha ayaa lagu qabtay Chengdu, kaas oo kiciyay dareenka caalamiga ah ee "horumarinta cagaaran". Maadaama Shiinuhu uu kaalinta koowaad ka galay qiiqa SO2, waa lama huraan in la xakameeyo qiiqa SO2 ee ka imanaya warshadaha muhiimka ah sida warshadaha korontada ku shaqeeya ee kulaylka iyo kuleyliyeyaasha dhuxusha lagu shido.

Waqtigan xaadirka ah, in ka badan 90% warshadaha korontada ku shaqeeya ee gudaha ayaa isticmaala tiknoolajiyada desulfurization-ka ee dhagaxa limestone-gypsum. Tiknoolajiyaddani waa mid qaangaar ah kharashkuna waa hooseeyaa. Labada habba waxay u baahan yihiin isticmaalka budada dhagaxa limestone si loo nuugo sulfur dioxide, marka cabbirka walxaha budada dhagaxa limestone-ka uu yaraado, ayaa sii kordhinaysa nuugista SO2.

1. Arrimaha ugu muhiimsan ee saameeya hufnaanta nadiifinta dhagaxa nuuradda

(1) Tayada dhagaxa nuuradda

Guud ahaan, maadada CaSO4 ee ku jirta dhagaxa nuuradda waa inay ka sarreysaa 85%. Haddii maaddada ay aad u yar tahay, waxay sababi doontaa dhibaatooyin shaqada ah oo ay ugu wacan tahay wasakh badan. Tayada dhagaxa nuuradda waxaa lagu go'aamiyaa maadada CaO. Inta badan ee daahirnimada dhagaxa nuuradda, ayaa ka sii wanaagsan hufnaanta dhagaxa nuuradda. Laakiin dhagaxa nuuradda daruuri ma laha wax ka badan CaO, way ka sii fiican tahay. Tusaale ahaan, dhagaxa nuuradda leh CaO>54% wuxuu leeyahay daahirnimo sare marmarna ma fududa in la shiido wuxuuna leeyahay xasillooni kiimiko oo xooggan, sidaa darteed kuma habboona in loo isticmaalo sidii wakiilka dhagaxa nuuradda.

(2) Cabbirka walxaha dhagaxa nuuradda (khafiifnimada)

Cabbirka cabbirka walxaha dhagaxa nuuradda ayaa si toos ah u saameeya xawaaraha falcelinta. Marka dusha sare ay weynaato, xawaaraha falcelinta ayaa si dhakhso ah u kordha falcelintuna waa mid dhammaystiran. Sidaa darteed, budada dhagaxa nuuradda ee badanaa loo baahan yahay waxay dhex mari kartaa shaandho 250 mesh ah ama shaandho 325 mesh ah, heerka baaritaankana wuxuu gaari karaa 90%.

(3) Saamaynta falgalka dhagaxa nuuradda ku leeyahay waxqabadka nidaamka nadiifinta sulfurization

Dhagaxa nuuradda leh oo leh firfircooni sare waxay gaari kartaa hufnaan sare oo ka saarista sulfur dioxide iyadoo la ilaalinayo heerka isticmaalka dhagaxa nuuradda. Falcelinta dhagaxa nuuradda waa mid sare, heerka isticmaalka dhagaxa nuuradda sidoo kale waa mid sareeya. CaCO2 xad-dhaafka ah ee ku jira gypsum-ka waa mid hooseeya, taas oo ah, daahirnimada gypsum-ka ayaa sareysa.

3. Mabda'a shaqada ee warshadda shiidda dhagaxa Raymond

Warshadda shiididda dhagaxa Raymond waxay ka kooban tahay shiididda martida, baaritaanka kala soocidda, ururinta alaabta iyo qaybo kale. Qaybta ugu weyn waxay qaadataa qaab-dhismeed saldhig ah oo la shubay, kaas oo loo isticmaali karo aasaas nuugaya shoog. Nidaamka kala soocidda wuxuu qaataa qaab-dhismeed kala soocidda mishiinnada qasabka ah, nidaamka ururintana wuxuu qaataa ururinta garaaca wadnaha.

(1) Mabda'a shaqada ee warshadda shiidda dhagaxa Raymond

Qalabka waxaa lagu jajabiyaa cabbir walax ah oo buuxiya shuruudaha gaarka ah ee mashiinka burburiyaha daanka, ka dibna waxaa kor u qaadaya wiishka baaldiga, ka dibna si tiro ahaan ah ayaa loogu shubaa qolka ugu weyn ee quudiyaha si loogu shiido. Qalabka duubista shiididda ee lagu taageerayo qaab-dhismeedka ubaxa tubta ee godka mashiinka ugu weyn wuxuu ku wareegayaa dhidibka dhexe. Roogga shiididda ayaa si toosan u ruxaya dibadda iyadoo la adeegsanayo xoogga centrifugal, si roogga shiididda uu u riixo giraanta shiididda roogga shiididdana uu isku mar ku wareego dhidibka shiididda. Walaxda uu kor u qaado daabka wareegaya waxaa lagu tuuraa inta u dhaxaysa roogga shiididda iyo giraanta shiididda, waxaana burburiya oo shiidiya roogga shiididda.

(2) Habka shaqada ee xulashada budada ee warshadda dhagaxa Raymond

Budada dhulka waxaa afuufaya qulqulka hawada ee afuufaya una gudbaya kala-soocidda ka sarreysa mashiinka ugu weyn ee loogu talagalay in lagu kala saaro. Budada aad u fiican oo qallafsan ayaa wali ku dhici doonta mashiinka ugu weyn ee dib loogu shiido, budada buuxisa shuruudahana waxay ku qulquli doontaa ururinta duufaanta iyadoo dabaysha wadata. Ka dib ururinta, badeecada la dhammeeyay waxaa laga sii daayaa tuubada dheecaanka budada (cabirka walxaha ee badeecada la dhammeeyay wuxuu noqon karaa ilaa 0.008mm). Hawada la nadiifiyay waxay ku qulqulaysaa afuufaya iyada oo loo marayo tuubada ku taal dhammaadka sare ee duufaanta. Waddada hawadu way wareegaysaa. Marka laga reebo cadaadiska togan ee ka imanaya afuufaya una gudbaysa qolka shiididda, socodka hawada ee dhuumaha kale wuxuu ku socdaa cadaadis taban. Xaaladaha nadaafadda gudaha waa kuwo wanaagsan.

Mashiinka shiididda dhagaxa dhagaxa ee Guilin Hongcheng Raymond waa casriyeyn farsamo oo ku salaysan warshadda shiididda nooca R. Tilmaamayaasha farsamada ee badeecadan si weyn ayaa loo hagaajiyay marka la barbar dhigo isla xilligii warshadda shiididda nooca R. Waa nooc cusub oo ah wax soo saar shiididda oo leh hufnaan sare iyo keydin tamar. Quruxda badeecada la dhammeeyay waxaa si aan kala sooc lahayn loogu hagaajin karaa inta u dhaxaysa 22-180μm (80-600 mesh).

(1) (Tiknoolajiyada cusub) Qalabka duubista ee ubaxa plum iyo qalabka shiididda ee dhererka leh waxay leeyihiin qaab-dhismeedyo horumarsan oo macquul ah. Mashiinku wuxuu leeyahay gariir aad u yar, buuq yar, hawlgal farsamo oo siman iyo waxqabad la isku halleyn karo.

(2) Mugga habaynta ee agabka halkii cutubba wakhtiga shiididda ayaa ka weyn hufnaantana way ka sarreysaa. Wax soo saarku wuxuu kordhay in ka badan 40% sannadkii, kharashka isticmaalka korontada ee cutubkuna wuxuu badbaadiyay in ka badan 30%.

(3) Meesha haraaga ah ee ka soo baxda warshadda shiididda waxaa ku qalabaysan qalab ururiya boodhka garaaca, kaas oo waxtarkiisa ururinta boodhka uu gaarayo 99.9%.

(4) Qaadashada qaab-dhismeedka shaabadaynta cusub, qalabka shiididda waxaa lagu buuxin karaa dufan hal mar 300-500 saacadood kasta.

(5) Iyada oo la adeegsanayo tignoolajiyada agabka birta ah ee chromium-ka oo u adkaysta xirashada gaarka ah, waxay ku habboon tahay xaaladaha isku dhaca badan iyo kuwa culus, cimriga adeegguna wuxuu ku dhawaad ​​saddex jeer ka dheer yahay heerka warshadaha.

In summary, compared with traditional Raymond mill, suspension roller mill, ball mill and other processes, the use of Raymond limestone mill can reduce energy consumption by 20% to 30%, which can improve the preparation of environmentally friendly desulfurized limestone powder.
