I-Limestone Raymond mill idlala indima ebalulekileyo ekulungiseleleni umgubo we-limestone oyekisiweyo ukuba unganyibiliki. Umgangatho we-Raymond limestone mill uchaphazela ngokuthe ngqo umgangatho, ubunono kunye nokusasazwa kobukhulu bamasuntswana e-limestone powder. Oku kulandelayo kuza kuchaza iimpawu zobugcisa kunye nokusetyenziswa okukhethekileyo kwe-Raymond limestone grinding mill ekususeni i-limestone pulverization.
I. Ukubaluleka kokusetyenziswa kweRaymond limestone mill ekucolweni kwe limestone engasetyenziswanga isulfuri
Okwangoku, ngaphezulu kwama-90% ezityalo zamandla obushushu eTshayina zisebenzisa itekhnoloji ye-limestone gypsum desulfurization, enobuchwepheshe obuvuthiweyo kunye nexabiso eliphantsi. Zombini ezi nkqubo zifuna umgubo we-limestone ukuze zifunxe i-sulfur dioxide, kwaye okukhona ubukhulu besuntswana lomgubo we-limestone buncinci, kokukhona kulungelelaniswa nokufunxwa kwe-SO2.
II. Izinto eziphambili ezichaphazela ukusebenza kakuhle kwe-desulfurization yelitye lekalika
(1) Umgangatho welitye lekalika
Ngokubanzi, umxholo weCaSO4 kwilitye lekalika kufuneka ube ngaphezulu kwe-85%. Ukuba umxholo uphantsi kakhulu, kuya kuzisa iingxaki ezithile ekusebenzeni ngenxa yokungcola okuninzi. Umgangatho welitye lekalika umiselwa ngumxholo weCao. Okukhona ubunyulu belitye lekalika buphezulu, kokukhona ukusebenza kakuhle kwe-desulfurization kungcono. Kodwa ilitye lekalika ayisiyomfuneko ukuba ibe ngumxholo weCaO, kokukhona iphezulu ingcono. Umzekelo, ilitye lekalika elineCao > 54% yiDali Petrochemical ngenxa yobunyulu bayo obuphezulu, akukho lula ukuyigaya kunye nozinzo oluqinileyo lweekhemikhali, ngoko ke ayifanelekanga ukusetyenziswa njenge-desulfurizer.
（2）Ubungakanani besuntswana yeLimestone (ubuncinci)
Ubungakanani bamasuntswana elitye lekalika buchaphazela ngokuthe ngqo izinga lokusabela. Xa indawo ethile yomphezulu inkulu, isantya sokusabela siyakhawuleza kwaye impendulo yanele ngakumbi. Ke ngoko, kudla ngokufuneka ukuba izinga lokudlula komgubo welitye lekalika ngesihluzo se-250 mesh okanye ngesihluzo se-325 mesh linokufikelela kwi-90%.
（3）Isiphumo sokusebenza kwe-limestone ekusebenzeni kwenkqubo ye-desulfurization
Ilitye lekalika elinomsebenzi ophezulu linokufikelela ekusebenzeni okuphezulu kokususa i-sulfur dioxide phantsi kwemeko yokugcina izinga elifanayo lokusetyenziswa kwelitye lekalika. Ilitye lekalika linomsebenzi ophezulu wokusabela, izinga eliphezulu lokusetyenziswa kwelitye lekalika kunye nomxholo ophantsi we-CaCO engaphezulu kwi-gypsum, oko kukuthi, i-gypsum icocekile kakhulu.
III. Umgaqo wokusebenza welitye le-Raymond mill
I-Raymond limestone mill yenziwe ngomatshini wokusila, ukuvavanya umgangatho, ukuqokelelwa kwemveliso kunye nezinye izinto. Injini ephambili isebenzisa isakhiwo sesiseko sokufaka i-integral casting, kwaye isiseko sokudambisa singasetyenziswa. Inkqubo yokwahlulahlula isebenzisa isakhiwo se-compulsive turbine classifier, kwaye inkqubo yokuqokelela isebenzisa ukuqokelelwa kwe-pulse.
(1) Umgaqo wokusebenza weRaymond limestone mill
Izinto ezisetyenziswayo zicolwa zibe bubungakanani obufanelekileyo besuntswana nge-jaw crusher, ziphakanyiswe ziye kwi-storage hopper nge-dustpan elevator, zize zithunyelwe ngokobuninzi kwi-main machine cavity nge-feeder ukuze zigaywe. I-main engine cavity ixhaswa kwi-plum blossom frame, kwaye isixhobo se-grinding roller sijikeleza kwi-central axis. I-grinding roller ijika ngokuthe tye ngaphandle phantsi kwesenzo samandla e-centrifugal, ukuze i-grinding roller icinezele i-grinding ring, kwaye i-grinding roller ijikeleze i-grinding roller shaft ngaxeshanye. Izinto eziphakanyiswe yi-rotary blade ziphoswe phakathi kwe-grinding roller kunye ne-grinding ring ukuze kufezekiswe umsebenzi wokutyumza nokugaywa ngenxa ye-roller grinding roller.
(2) Inkqubo yokusebenza kweRaymond limestone mill kunye ne-separator
Umgubo ocoliweyo uvuthuzwa ngumoya ophuma kwi-blower ukuya kwi-classifier engaphezulu komatshini oyintloko ukuze uhlolwe, kwaye umgubo ocolekileyo norhabaxa usawela kumatshini oyintloko ukuze ubuye ucolwe. Ukuba ubuncinci buhambelana nemiyalelo, ungena kwi-cyclone collector enomoya kwaye ukhutshwa ngombhobho wokukhupha umgubo emva kokuqokelela, okuyimveliso egqityiweyo (ubungakanani besuntswana yemveliso egqityiweyo bunokuba phezulu njenge-0.008mm). Umoya ocociweyo ungena kwi-blower ngombhobho okwisiphelo esiphezulu se-cyclone, kwaye indlela yomoya iyajikeleza. Ngaphandle koxinzelelo oluhle oluvela kwi-blower ukuya kwigumbi lokusila, ukuhamba komoya kwezinye iipayipi kuhamba phantsi koxinzelelo olubi, kwaye iimeko zococeko zangaphakathi zilungile.
IV. Iimpawu zobugcisa zeRaymond limestone mill
I-Limestone Raymond mill eyenziwe yi-HCMilling (Guilin Hongcheng) luhlaziyo lobuchwephesha olusekelwe kwi-R-type grinding mill. Ii-index zobugcisa zemveliso ziphuculwe kakhulu xa kuthelekiswa nomatshini wohlobo lwe-R. Luhlobo olutsha lwe-grinding mill olusebenza kakuhle kwaye lugcina amandla. Ubunzima beemveliso ezigqityiweyo bunokuba yi-22-180 μ M (80-600 mesh).
（1）(Iteknoloji Entsha) ifreyimu yentyatyambo yeplum kunye nesixhobo sokusila esijijayo esithe nkqo, esinesakhiwo esiphucukileyo nesifanelekileyo. Umatshini unentshukumo ephantsi kakhulu, ingxolo ephantsi, ukusebenza okuzinzileyo kunye nokusebenza okuthembekileyo.
（2）Umthamo wokucubungula wezixhobo ngexesha lokusila iyunithi mkhulu kwaye ukusebenza kakuhle kuphezulu. Imveliso inyuke ngaphezu kwe-40% unyaka nonyaka, kwaye iindleko zokusetyenziswa kwamandla eyunithi zigcinwe ngaphezulu kwe-30%.
（3）Indawo eseleyo yokukhupha umoya kwi-pulverizer ixhotyiswe ngesixhobo sokuqokelela uthuli lwe-pulse, kwaye ukusebenza kakuhle kokuqokelela uthuli kufikelela kwi-99.9%.
（4）Isebenzisa uyilo olutsha lwesakhiwo sokutywina, kwaye isixhobo sokusila esijikelezayo sinokuzalisa igrisi kanye emva kweeyure ezingama-300-500.
（5）Isebenzisa ubuchwepheshe obukhethekileyo be-chromium alloy enganyangekiyo, obufaneleke ngakumbi kwiimeko zokungqubana nokuqengqeleka ezinamaza amaninzi kunye nomthwalo omkhulu, kwaye ubomi bayo benkonzo buphantse buphindwe kathathu kunomgangatho weshishini.
Xa kuthelekiswa neRaymond mill yendabuko, i-suspension roller mill, i-ball mill kunye nezinye iinkqubo, i-limestone Raymond mill inokunciphisa ukusetyenziswa kwamandla nge-20% ~ 30%, kwaye inokuphucula ukulungiswa kwe-desulfurization limestone powder enobuhlobo nokusingqongileyo.
