Limestone Raymond niƙa taka muhimmiyar rawa a shirya desulfurized limestone foda.A ingancin Raymond farar ƙasa niƙa kai tsaye rinjayar ingancin, fineness da barbashi size rarraba farar ƙasa foda.Wadannan za su bayyana fasaha halaye da takamaiman aikace-aikace na Raymond farar ƙasa nika niƙa a desulfurization farar ƙasa pulverization.
I.Mahimmancin aikace-aikacen niƙa na niƙa na Raymond a cikin ɓarkewar farar ƙasa
A halin yanzu, fiye da kashi 90% na kamfanonin samar da wutar lantarki a kasar Sin sun yi amfani da fasahar sarrafa sinadarin gypsum na lemun tsami, wadda ke da fasahar da balagagge da tsada.Dukansu matakai suna buƙatar foda na farar ƙasa don shayar da sulfur dioxide, kuma ƙarami girman ƙwayar ƙwayar foda shine, mafi dacewa ga sha na SO2.
II.Main abubuwan da ke shafar aikin desulfurization na farar ƙasa
(1) Ingantacciyar farar ƙasa
Gabaɗaya, abun ciki na CaSO4 a cikin farar ƙasa zai zama sama da 85%.Idan abun ciki ya yi ƙasa sosai, zai kawo wasu matsaloli ga aikin saboda ƙarin ƙazanta.An ƙayyade ingancin farar ƙasa ta hanyar abun ciki na Cao.Mafi girma da tsarki na farar ƙasa, mafi kyawun ingancin desulfurization.Amma farar ƙasa ba dole ba ne abun ciki na CaO ba, mafi girma shine mafi kyau.Misali, farar ƙasa tare da Cao> 54% shine Dali Petrochemical saboda girman tsarkinsa, ba sauƙin niƙa da kwanciyar hankali mai ƙarfi ba, don haka bai dace da amfani da shi azaman desulfurizer ba.
(2) Girman barbashi na farar ƙasa (fineness)
Girman barbashi na farar ƙasa kai tsaye yana rinjayar ƙimar amsawa.Lokacin da takamaiman yanki ya fi girma, saurin amsawa yana da sauri kuma abin ya fi isa.Sabili da haka, yawanci ana buƙatar adadin wucewar foda na farar ƙasa ta hanyar 250 raga sieve ko 325 raga sieve zai iya kaiwa 90%.
(3) Tasirin reactivity na farar ƙasa akan aikin tsarin desulfurization
Dutsen farar ƙasa tare da ayyuka mafi girma na iya samun ingantaccen kawar da sulfur dioxide a ƙarƙashin yanayin kiyaye ƙimar amfani da farar ƙasa iri ɗaya.Dutsen farar ƙasa yana da babban aiki na amsawa, ƙimar amfani da dutsen farar ƙasa da ƙarancin abun ciki na wuce haddi na CaCO a cikin gypsum, wato, gypsum yana da tsafta.
III.Aikin ka'idar farar ƙasa Raymond niƙa
Raymond limestone niƙa ya ƙunshi mai masaukin niƙa, tantance ma'auni, tarin samfura da sauran abubuwan haɗin gwiwa.Babban injin yana ɗaukar tsarin tushe na simintin gyare-gyare, kuma ana iya ɗaukar tushe mai damping.Tsarin rarrabuwa yana ɗaukar tsarin ƙirar turbine na tilas, kuma tsarin tarin yana ɗaukar tarin bugun jini.
(1) Ka'idar aiki na Raymond limestone niƙa
Ana murƙushe kayan zuwa ƙwararrun ƙwayoyin barbashi ta hanyar muƙamuƙi, an ɗaga su zuwa wurin ajiya ta lif ɗin ƙura, sa'an nan kuma a ƙididdige su zuwa babban rami na inji ta mai ciyarwa don niƙa.Ana goyan bayan babban rami na injin akan firam ɗin furen plum, kuma na'urar niƙa tana jujjuyawa a tsakiyar axis.Abin nadi na niƙa yana jujjuya shi a zahiri a waje ƙarƙashin aikin ƙarfin centrifugal, don haka abin nadi na niƙa yana danna zoben niƙa, kuma abin nadi yana jujjuya mashin abin nadi a lokaci guda.Abubuwan da aka ɗaga ta hanyar jujjuya ruwa ana jefa su a tsakanin injin niƙa da zoben niƙa don cimma aikin murƙushewa da niƙa saboda abin nadi na niƙa.
(2)Tsarin aiki na Raymond limestone niƙa da SEPARATOR
Ana hura foda ta ƙasa ta iskar mai busa zuwa na'ura mai ƙira da ke sama da babban injin don tantancewa, kuma foda mai kyau da mara nauyi har yanzu tana faɗowa cikin babban injin don sake niƙawa.Idan fineness ya hadu da ƙayyadaddun ƙayyadaddun bayanai, yana gudana a cikin mai karɓar cyclone tare da iska kuma an sake shi ta hanyar bututun fitar da foda bayan tattarawa, wanda shine ƙãre samfurin (girman barbashi na ƙãre samfurin na iya zama kamar 0.008mm).Tsaftataccen iska yana gudana zuwa cikin mai busa ta cikin bututu a saman ƙarshen guguwar, kuma hanyar iska tana yawo.Sai dai matsi mai kyau daga mai busawa zuwa ɗakin nika, iska mai gudana a cikin sauran bututun yana gudana a ƙarƙashin mummunan matsi, kuma yanayin tsabta na cikin gida yana da kyau.
IV.Technical halaye na Raymond limestone niƙa
Limestone Raymond niƙa wanda HCMilling (Guilin Hongcheng) ya samar shine sabuntawar fasaha bisa nau'in niƙa na R.An inganta fihirisar fasaha na samfurin sosai idan aka kwatanta da na'ura mai nau'in R.Wani sabon nau'in niƙa ne tare da babban inganci da ceton kuzari.Lalacewar samfuran ƙãre na iya zama 22-180 μM (80-600 raga).
(1) (New Technology) plum blossom frame da a tsaye lilo nika abin nadi na'urar, tare da ci-gaba da m tsari.Na'urar tana da ƙananan rawar jiki, ƙaramar amo, aikin barga da ingantaccen aiki.
(2) The aiki iya aiki na kayan a naúrar nika lokaci ne ya fi girma da kuma yadda ya dace ne mafi girma.Abubuwan da aka fitar ya karu da fiye da 40% na shekara-shekara, kuma an adana kuɗin wutar lantarki na naúrar da fiye da 30%.
(3) Ragowar tashar iska na pulverizer sanye take da mai tara ƙura, kuma ingancin tarin ƙura ya kai kashi 99.9%.
(4) Yana ɗaukar sabon ƙirar tsarin rufewa, kuma na'urar niƙa na iya cika mai sau ɗaya kowane awa 300-500.
(5) Yana ɗaukar fasaha ta musamman mai jure lalacewa mai ƙarfi na chromium gami, wanda ya fi dacewa da haɗuwa da yanayin mirgina tare da babban mita da babban nauyi, kuma rayuwar sabis ɗin ta kusan sau uku na daidaitattun masana'antu.
Idan aka kwatanta da na gargajiya Raymond niƙa, dakatar abin nadi niƙa, ball niƙa da sauran matakai, da farar ƙasa Raymond niƙa iya rage makamashi amfani da 20% ~ 30%, kuma zai iya inganta da shirye-shiryen na muhalli m desulfurization farar ƙasa foda.
