Mphero ya Limestone Raymond imagwira ntchito yofunika kwambiri pokonza ufa wa miyala yamchere wosasungunuka. Ubwino wa mphero ya miyala yamchere ya Raymond umakhudza mwachindunji ubwino, kusalala ndi kukula kwa tinthu tating'onoting'ono ta ufa wa miyala yamchere. Zotsatirazi zifotokoza makhalidwe aukadaulo ndi momwe mphero yopera miyala yamchere ya Raymond imagwiritsidwira ntchito pochotsa sulfurization.
I. Kufunika kwa mphero ya miyala ya Raymond pa kupukutira miyala ya miyala yamchere yopanda sulfure
Pakadali pano, mafakitale opitilira 90% amagetsi otentha ku China akugwiritsa ntchito ukadaulo wa gypsum desulfurization wa limestone, womwe uli ndi ukadaulo wokhwima komanso wotsika mtengo. Njira zonsezi zimafuna ufa wa limestone kuti utenge sulfur dioxide, ndipo tinthu tating'onoting'ono ta ufa wa limestone tikakhala tating'ono, zimathandiza kwambiri kuyamwa kwa SO2.
II. Zinthu zazikulu zomwe zimakhudza mphamvu ya miyala yamchere yochotsera sulfurization
(1) Ubwino wa miyala ya laimu
Kawirikawiri, kuchuluka kwa CaSO4 mu miyala yamchere kuyenera kukhala kokwera kuposa 85%. Ngati kuchuluka kwake kuli kochepa kwambiri, kumabweretsa mavuto ena chifukwa cha zinyalala zambiri. Ubwino wa miyala yamchere umatsimikiziridwa ndi kuchuluka kwa Cao. Kuyera kwa miyala yamchere kukakhala kwakukulu, mphamvu ya desulfurization imakhala yabwino kwambiri. Koma miyala yamchere sikutanthauza kuti ili ndi CaO, ndiye kuti imakhala yabwino kwambiri. Mwachitsanzo, miyala yamchere yokhala ndi Cao > 54% ndi Dali Petrochemical chifukwa cha kuyera kwake kwakukulu, kosavuta kupukutidwa komanso kukhazikika kwamphamvu kwa mankhwala, kotero sikoyenera kugwiritsidwa ntchito ngati desulfurizer.
(2) Kukula kwa tinthu ta miyala ya laimu (kupyapyala)
Kukula kwa tinthu ta miyala yamchere kumakhudza mwachindunji kuchuluka kwa zomwe zimachitika. Pamene malo enieniwo ali akulu, liwiro la zomwe zimachitika limakhala lachangu ndipo zomwe zimachitika zimakhala zokwanira. Chifukwa chake, nthawi zambiri pamafunika kuti ufa wa miyala yamchere udutse mu sieve ya 250 mesh kapena sieve ya 325 mesh ufike pa 90%.
（3） Zotsatira za reactivity ya miyala yamchere pa magwiridwe antchito a dongosolo la desulfurization
Mwala wa limestone wokhala ndi ntchito yayikulu ukhoza kuchotsa bwino sulfur dioxide pokhapokha ngati uli ndi mphamvu yogwiritsira ntchito miyala ya limestone yofanana. Mwala wa limestone uli ndi mphamvu yochitapo kanthu kwambiri, mphamvu yogwiritsira ntchito miyala ya limestone yochuluka komanso CaCO yochuluka yochepa mu gypsum, ndiko kuti, gypsum ili ndi chiyero chapamwamba.
III. Mfundo yogwirira ntchito ya mphero ya miyala ya Raymond
Mphero ya miyala ya Raymond imapangidwa ndi makina opukutira, kuwunikira ma grading, kusonkhanitsa zinthu ndi zinthu zina. Injini yayikulu imagwiritsa ntchito kapangidwe ka maziko oyambira, ndipo maziko opopera amatha kugwiritsidwa ntchito. Dongosolo logawa magawo limagwiritsa ntchito kapangidwe ka turbine classifier yofunikira, ndipo dongosolo losonkhanitsa limagwiritsa ntchito kusonkhanitsa kwa pulse.
(1) Mfundo yogwirira ntchito ya mphero ya miyala ya Raymond
Zipangizozo zimaphwanyidwa kukhala tinthu tating'onoting'ono toyenerera ndi chitoliro cha jaw crusher, zimakwezedwa ku hopper yosungiramo zinthu pogwiritsa ntchito chitoliro cha fumbi, kenako zimatumizidwa ku malo osungiramo zinthu pogwiritsa ntchito chodyetsa kuti ziphwanyidwe. Malo osungiramo zinthu akuluakulu a injini amathandizidwa ndi chimango cha plum bloom, ndipo chipangizo chopukusira chimazungulira mozungulira mzere wapakati. Chopukusira chimagwedezeka mopingasa ndi mphamvu ya centrifugal, kotero kuti chopukusira chimakankhira mphete yopukusira, ndipo chopukusira chimazungulira shaft yopukusira nthawi yomweyo. Zinthu zomwe zimakwezedwa ndi tsamba lozungulira zimaponyedwa pakati pa chopukusira ndi mphete yopukusira kuti zikwaniritse ntchito yophwanya ndi kuphwanya chifukwa cha chopukusira chopukusira.
(2) Njira yogwirira ntchito ya mphero ya miyala ya Raymond ndi cholekanitsa
Ufa wophwanyika umawulutsidwa ndi mpweya wotuluka kuchokera ku chowulutsira mpweya kupita ku chogawira pamwamba pa makina akuluakulu kuti ukhale wowunika, ndipo ufa wosalala ndi wosalala umagwerabe mu makina akuluakulu kuti upukutenso. Ngati kusalalako kukukwaniritsa zomwe zafotokozedwa, umalowa mu chosonkhanitsa mphepo ndi mphepo ndipo umatuluka kudzera mu chitoliro chotulutsira mpweya pambuyo posonkhanitsa, chomwe ndi chinthu chomalizidwa (kukula kwa tinthu ta chinthu chomalizidwa kumatha kukhala 0.008mm). Mpweya woyeretsedwa umalowa mu chowulutsira mpweya kudzera mu chitoliro chomwe chili kumapeto kwa chivolicho, ndipo njira ya mpweya imazungulira. Kupatula kupanikizika kwabwino kuchokera ku chowulutsira mpweya kupita ku chipinda chopukusira, mpweya m'mapaipi ena umalowa pansi pa kupsinjika koipa, ndipo ukhondo wamkati ndi wabwino.
IV. Makhalidwe aukadaulo a mphero ya miyala ya Raymond
Mphero ya Limestone Raymond yopangidwa ndi HCMilling (Guilin Hongcheng) ndi yosinthidwa mwaukadaulo kutengera mphero yopukutira ya mtundu wa R. Ma index aukadaulo a chinthucho asinthidwa kwambiri poyerekeza ndi makina a mtundu wa R. Ndi mtundu watsopano wa mphero yopukutira yomwe imagwira ntchito bwino kwambiri komanso yosunga mphamvu. Kusalala kwa zinthu zomalizidwa kumatha kukhala 22-180 μ M (80-600 mesh).
（1）(Ukadaulo Watsopano) chimango cha maluwa a plum ndi chipangizo chopukutira chozungulira chozungulira, chokhala ndi kapangidwe kapamwamba komanso koyenera. Makinawa ali ndi kugwedezeka kochepa kwambiri, phokoso lochepa, magwiridwe antchito okhazikika komanso magwiridwe antchito odalirika.
（2） Mphamvu yogwiritsira ntchito zipangizo mu nthawi yopera mayunitsi ndi yayikulu ndipo magwiridwe antchito ndi apamwamba. Kutulutsa kwa zinthu kunawonjezeka ndi oposa 40% chaka ndi chaka, ndipo ndalama zogwiritsira ntchito mphamvu za mayunitsi zinapulumutsidwa ndi oposa 30%.
（3）Njira yotsalira yotulutsira mpweya ya pulverizer ili ndi chosonkhanitsira fumbi, ndipo mphamvu yake yosonkhanitsira fumbi imafika 99.9%.
（4）Imagwiritsa ntchito kapangidwe katsopano kotsekera, ndipo chipangizo chopukusira chozungulira chimatha kudzaza mafuta kamodzi maola 300-500 aliwonse.
（5）Imagwiritsa ntchito ukadaulo wapadera wosagwiritsidwa ntchito ndi chromium alloy, womwe ndi woyenera kwambiri pakakhala kugundana ndi kugubuduzika ndi ma frequency ambiri komanso katundu wambiri, ndipo nthawi yake yogwirira ntchito ndi pafupifupi katatu kuposa muyezo wamakampani.
Poyerekeza ndi mphero yachikhalidwe ya Raymond, mphero yopumira yopumira, mphero ya mpira ndi njira zina, mphero ya limestone ya Raymond imatha kuchepetsa kugwiritsa ntchito mphamvu ndi 20% ~ 30%, ndipo imatha kukonza bwino ufa wa limestone wosawononga chilengedwe.
