Pamene dzikolo likuika kufunika kwa kuteteza chilengedwe, monga mtundu wa zinyalala zolimba, momwe mungagwiritsire ntchito chitsulo chosungunuka chakhala nkhani yofunika kwambiri. Nkhaniyi ikubweretsa njira yokwanira yaukadaulo yobwezeretsanso chitsulo chosungunuka. Ukadaulo wokonza zinthu zouma uyenera kuonetsetsa kuti zitsulo zibwezeretsedwa bwino mbali imodzi ndikugwiritsa ntchito bwino zinyalala mbali inayo. Njira zotsatirazi zokonzera chitsulo chosungunuka zafotokozedwa: Kuphwanya kosankha; kulekanitsa maginito ndi ntchito ya mphero yatsopano yoyendetsa ndi mphamvu yayikulu yopopera mphamvu imodzi pakugwiritsa ntchito chitsulo chosungunuka; kugwiritsa ntchito zida zatsopano kungachepetse kwambiri mtengo wopopera chitsulo chosungunuka, motero kumapanga ubwino wambiri pakugwiritsa ntchito chitsulo chosungunuka. Kukwezedwa kwa kugwiritsa ntchito chitsulo chosungunuka kwapanga mwayi. Kukwezedwa kwa lingaliro lonseli m'makampani kumafuna khama logwirizana la makampani opanga zitsulo, akatswiri opanga mchere ndi akatswiri, kukhazikitsa ntchito yonse, ndi madipatimenti otsatsa ndi kukweza.
Kugwiritsa ntchito chitsulo chosungunuka m'madzi
1) Simenti yachitsulo imagwiritsidwa ntchito popanga simenti ndi zosakaniza za konkriti. Simenti yachitsuloyi ili ndi mchere wogwira ntchito monga tricalcium silicate (C3S), dicalcium silicate (C2S) ndi iron aluminate yokhala ndi mphamvu zomangira simenti ya hydraulic, zomwe zimagwirizana ndi makhalidwe a simenti. Chifukwa chake, ingagwiritsidwe ntchito ngati zinthu zopangira simenti komanso ngati chosakaniza cha simenti popanga simenti yosakanizika, simenti yochepa ya clinker. Simenti yachitsulo yokhala ndi zinthu zabwino kwambiri monga kukana kuwonongeka, mphamvu yolimba yopindika, kukana dzimbiri komanso kukana chisanu.
2) Chitsulo chosweka chimalowa m'malo mwa miyala yosweka ndi miyala yosalala. Chitsulo chosweka miyala chili ndi ubwino wokhala ndi mphamvu zambiri, malo ouma, kukana kuwonongeka bwino komanso kulimba, kuchuluka kwakukulu, kukhazikika bwino, komanso kuphatikiza kolimba ndi phula. Poyerekeza ndi miyala wamba yosweka, imalimbananso ndi ming'alu yotsika kutentha, kotero ingagwiritsidwe ntchito kwambiri pokonzanso misewu. Chitsulo chosweka, monga ballast ya sitima, chili ndi makhalidwe osasokoneza ntchito yolumikizirana ya sitima komanso kuyendetsa bwino magetsi. Chifukwa chitsulo chosweka chili ndi madzi okwanira komanso madzi otuluka bwino, zinthu zomwe zili mkati mwake zimatha kupangitsa kuti chikhale cholimba kwambiri. Chitsulo chosweka chimathandizanso kumanga misewu m'madambo ndi m'mphepete mwa nyanja.
Pakadali pano, njira yodziwika bwino yogwiritsira ntchito chitsulo chosungunuka m'nyumba ndi kuphwanya chitsulo chosungunuka mpaka -5mm kuti chilowe m'malo mwa mchenga wa m'mtsinje ngati zinthu zomangira, kapena kupukuta chitsulo chosungunukacho kukhala ufa wosalala kuti chigwiritsidwe ntchito ngati chowonjezera cha simenti. Shandong Huate Magnetoelectric Technology Co., Ltd. yachitanso kafukufuku wozama pakugwiritsa ntchito chitsulo chosungunuka m'madzi, mwaluso yagwiritsa ntchito mphero yozungulira yokhala ndi mphamvu yothamanga imodzi pophwanya chitsulo chosungunuka m'madzi, yakweza ukadaulo wopangira chitsulo chosungunuka m'madzi, ndipo yapeza phindu labwino pazachuma. Yagwiritsidwa ntchito bwino ku Pangang Mining ndi ku kampani ina yachitsulo chosungunuka m'madzi ku Lianyungang.
Njira yopangira chitsulo chachitsulo chachikhalidwe ndi iyi:
1) Zidutswa zazikulu zimaphwanyidwa ndi chotsukira nsagwada mpaka -50, ndipo chitsulo cha maginito chimalekanitsidwa ndi pulley ya maginito.
2) Ikani kukula kwa chitsulocho kufika pa +45 mm. 0-45 mm yotsala nthawi zambiri imagwiritsidwa ntchito ngati njira yopangira misewu ndi zinthu zodzaza. Pofuna kuwonjezera phindu lake, chitsulo chosungunuka chingagawidwe m'magulu a 0-4, 4-8 ndi mitundu ina yosiyanasiyana. Ukadaulowu umafuna ndalama zochepa komanso ndalama zochepa zogwirira ntchito. Komabe, chitsulo chosungunuka choposa 50% chimakhala ndi mphamvu ya -10 mm, kotero ukadaulo uwu udzapangitsa kuti chitsulocho chitayike kwambiri, koma chitsulo cholemera chidzawonjezeka.
Chifukwa chake, kupukusa konyowa kwagwiritsidwa ntchito kwambiri makamaka pa slag yopangidwa popanga chitsulo chapamwamba chokhala ndi Cr, Ni, Mo, ndi zina zotero. Njira zodziwika bwino zimaphatikizapo kuphwanya ndi kupukusa konona kwa magawo awiri (mphero ya ndodo/mphero ya mpira). Popeza chitsulo chokhala ndi ductility sichili chosavuta kupukusa, kulekanitsa slag yachitsulo ndi chitsulo kumatha kuchitika popukusa kapena kugawa. Kusalala kwa gawo la mchere la slag nthawi zambiri kumakhala pamwamba pa 95% ndi pansi pa 0.2mm. Kuchuluka kwa kubwezeretsa chitsulo kwa njirayi kumaposa 95%, ndipo zokolola za chitsulo zomwe zimapangidwa ndi 90 mpaka 92%. Kuchokera pamalingaliro olekanitsa chitsulo ndi slag, njirayi inganenedwe kuti ndiyo njira yabwino kwambiri.
Vuto lalikulu la njirayi ndilakuti chitsulo cholekanitsidwacho chimakhala ndi matope osalala. Chifukwa chakuti njirayi ndi yonyowa, zimakhala zovuta kugwiritsa ntchito pomanga nyumba. Chifukwa chake, zinthu zambiri zachitsulo zotsala mutasankha chitsulo zimatayidwa, ndipo nthawi zambiri izi zimachitika chifukwa cha mtengo wokwera wa kuumitsa konyowa komanso zoletsa zalamulo padziko lonse lapansi. Kugwiritsa ntchito kulikonse kwamtengo wapatali kumafuna njira zina zochizira matope onyowa (kuumitsa, kukhuthala, ndi zina zotero).
Kawirikawiri kusankha kuyenera kupangidwa pakati pa kuchuluka kwa kubweza chitsulo kapena kupezeka kwa slag yotsala. Nthawi zambiri, kusankha kumeneku kumadalira mtengo wa chitsulo chobwezedwacho.
Njira zodziwika bwino pa siteji iyi ndi izi:
Zidutswa zazikulu zimaphwanyidwa ndi chotsukira nsagwada mpaka -50, ndipo chitsulo cha maginito chimalekanitsidwa ndi pulley ya maginito.
Chitsulo chopanda zitsulo cha -50 chimaphwanyidwa ndi chotsukira cha hammer kapena chotsukira cha cone, chotsukira cha impact, chosefedwa kudzera mu sieve ya multilayer, chotsukira cha -20-10 chingagwiritsidwe ntchito ngati miyala, chotsukira cha -10-1 chingagwiritsidwe ntchito ngati mchenga wabwino.

Kusanthula kukula kwa tinthu tating'onoting'ono ta 50mm mu nyundo crusher
-10 chitsulo chosungunuka chimaphwanyidwa mu mphero youma kukhala ufa wosalala wa -200, kenako cholekanitsa maginito cha ufa wouma chamagetsi chimagwiritsidwa ntchito kuchotsa chitsulo ngati chowonjezera cha simenti.
