Mlandu wa mphero yopukutira ya Guilin Hongcheng laimu
Laimu ndi mtundu wa zinthu zopangira simenti zopangidwa ndi mpweya zomwe zimakhala ndi calcium oxide ngati gawo lalikulu, zomwe zimagwira ntchito yofunika kwambiri popanga zitsulo zachitsulo. Kodi ufa wa laimu umagwira ntchito bwanji popanga zitsulo zachitsulo? Ndi mphero iti yomwe imagwiritsidwa ntchito popanga zitsulo zopangira ufa wa laimu?Fakitale yopangira zida zopangira laimu ya Guilin Hongchengimayambitsa ukadaulo wokonza ufa wa laimu popanga zitsulo.
1. Kodi ufa wa laimu womwe umagwiritsidwa ntchito ndi chitsulo umakhala ndi zotsatira zotani?
(1).kuchotsa sulfure, phosphorous, silicon, arsenic ndi zinthu zina zovulaza: chifukwa ma oxide a zinthu zovulaza izi nthawi zambiri amakhala zinthu zina za acidic, kotero ndi njira yothandiza kuziphatikiza ndi zinthu zina za alkaline kuti apange mankhwala okhazikika. Komabe, block calcium oxide, yokhala ndi gwero lolemera la zinthu zopangira komanso mtengo woyenera, imatha kupanga mankhwala osiyanasiyana kuchokera ku ma oxide a S, P, Si ndi As, ndipo imakhala chisankho chabwino kwambiri chochotsera S, P, Si ndi As.
（2）Kuchotsa mpweya m'thupi: Zotsatira za metallurgy yamakono zikusonyeza kuti kuchotsa mpweya m'thupi makamaka ndi njira yosalunjika yochotsera mpweya m'thupi, mpweya woyamba kuchotsera mpweya m'thupi, pakati pa chitsulo chosungunuka m'thupi mu njira yochotsera mpweya m'thupi, ndipo pansi pa slag CaO/SiO2₂ pa slag chitsulo chosungunuka m'thupi kuti chigwirizane ndi kusintha kwa kayendedwe ka mpweya m'thupi, kufalikira kwa mpweya m'thupi kumakhudza kwambiri, ndipo kumapangitsa kuti mpweya m'thupi utuluke m'thupi, zomwe zimapangitsa kuti mpweya utuluke m'thupi.
（3）Chitetezo cha ng'anjo: asidi Fe ₂O ₃ mu zotsalira ndi SiO ₂ zimatha kuchitapo kanthu mosavuta ndi alkaline substance MgO mu ng'anjo kuti ziwononge ng'anjo. Powonjezera calcium oxide, asidi awa amakhudzanso kwambiri ndi calcium oxide. Chifukwa chake, kuyambira pa ng'anjo yoteteza, calcium oxide imagwiritsidwa ntchito ngati chinthu chotsitsa, chomwe chimachepetsa bwino liwiro la kuwonongeka kwa ng'anjo.
（4）Chepetsani kufalikira kwa chitsulo: chinthu chokhala ndi asidi mu slag Fe ₂O ₃ ndi SiO ₂ chimatha kuchitapo kanthu mosavuta ndi chinthu cha alkaline MgO mu ng'anjo kuti chiwononge ng'anjo. Powonjezera calcium oxide, zinthuzi zimakhala ndi asidi makamaka ndi calcium oxide. Chifukwa chake, kuyambira pa ng'anjo yoteteza, calcium oxide imagwiritsidwa ntchito ngati slag, yomwe ingathandize kuchepetsa kuwonongeka kwa ng'anjo. Kuwonjezera ufa wa laimu mu chitsulo chosungunuka kapena madzi achitsulo kumagwiritsidwa ntchito ngati chopangira slag popanga chitsulo kapena kupanga chitsulo, ndipo zonyansa zovulaza monga sulfure kapena phosphorous mu chitsulo chosungunuka kapena madzi achitsulo zimathanso kuchotsedwa panthawiyi.
2. Ndi mphero iti yomwe imagwiritsidwa ntchito popanga zitsulo pokonza ufa wa laimu?
Kusalala kwa ufa wa laimu womwe umagwiritsidwa ntchito m'mafakitale achitsulo nthawi zambiri kumakhala pafupifupi maukonde 120, ndipo kuchuluka kwa ufa wa laimu womwe umagwiritsidwa ntchito popanga zitsulo ndi kwakukulu, kotero mphamvu ya zida ndi yayikulu. Kupera kwa mphero yoyimirira ya Guilin Hongcheng kuli ndi zabwino izi:
Magawo aukadaulo a mphero yopukutira yoyimirira ya Guilin Hongcheng
(1) Kuyenda kosavuta kwa njira, zida zochepa zothandizira, zimakhala m'dera laling'ono;
(2) Chitetezo cha chilengedwe, dongosolo lonse la ndondomeko lili lotsekedwa mokwanira, ntchito yoipa ya kupanikizika, siiyendetsa fumbi, kutulutsa fumbi kumafika pamlingo wadziko lonse wochepera 30 mg/m3, ntchito yosalala ya ndondomeko, phokoso la dongosolo ndi lochepa;
(3) Kutayika kwa zida zomwe zili pachiwopsezo ndi kochepa, gulu la zida zomwe zili pachiwopsezo zimatha kugwira ntchito kwa zaka zoposa ziwiri;
(4) Dongosolo lonse limapangidwa ndi opanga akatswiri, mulingo wopanga nawonso ndi wapamwamba kwambiri, kotero magwiridwe antchito a dongosololi ndi okwera, amatha kugwira ntchito maola 24 mosalekeza, kuchuluka kwa magwiridwe antchito a zida kumatha kufika pa 95%;
(5) Kusunga mphamvu ndi kusunga magetsi, poyerekeza ndi zida zina, kumatha kusunga magetsi opitilira 50%.
(6) Mphamvu yabwino yopera: makina opangira zinthu ali ndi mphamvu zambiri (kutulutsa kwa nsanja yayikulu ya zida kumatha kufika matani opitilira 100), magwiridwe antchito apamwamba, chinthucho chimatha kukwaniritsa zosowa zenizeni;
(7)Compared with other equipment at home and abroad, the whole system is simple, convenient operation and maintenance, the professional requirements for operators are not high, generally suitable for the preparation of lime powder in various types of domestic enterprises, and can save labor costs; Less equipment loss, less iron pollution, the color of the grinding product will not change, the whole process is closed negative pressure operation, do not discharge dust, and will not bring in pollutants.Consulting the price of Guilin Hongcheng lime vertical grinder, welcome to contact email: mkt@hcmilling.com
