Uhlelo lokujova amalahle oluqhumile olusebenzisa isithando somlilo lunezindlela eziningi zokusetshenziswa embonini yamandla kagesi, insimbi kanye ne-metallurgical. Kuyo yonke isistimu, ukulungiswa kwamalahle aqhumile kuyisixhumanisi esibalulekile, futhi ikhwalithi yamalahle aqhumile akhiwe ukucutshungulwa kwamalahle aluhlaza inquma ukusebenza kahle kwesistimu yonke. Ngenxa yezidingo eziphezulu zamalahle aqhumile kanye nomkhiqizo omkhulu, umshini wokugaya amalahle wendabuko awukwazi ukuhlangabezana nezidingo zawo. Ngenxa yalokho, amakhasimende amaningi aphendukela ekugxileni kwawo umshini omusha wamalahle oqondile. I-HCMilling (Guilin Hongcheng), njengomkhiqizi womshini wokugaya amalahle oqondile, wethuI-HLM ihlutshiwe amalahleumshini wokugaya oqondileisetshenziswe kabanzi futhi yaqashelwa ku- impuphu yomjovo wamalahleumshini wokugaya oqondile umugqa wokukhiqiza. Okulandelayo yisingeniso ezinzuzweni zobuchwepheshe zokucubungula amalahle aqoshiwe aqondile ajikelezayo aqoshiwe:

Impuphu yomjovo wamalahleumshini wokugaya oqondile

Inqubo ephelele yokujova amalahle aqothulwe ngesithando somlilo kufanele ifake uhlelo lokugcina amalahle aluhlaza kanye nokuthutha, uhlelo lokuchoboza, uhlelo lokudlulisa amalahle aqothulwe, uhlelo lokujova, uhlelo lokuphakelwa kwegesi kanye nohlelo lokulinganisa amalahle aqothulwe. Isikhungo sokulawula ikhompyutha sohlelo lokujova amalahle. Uhlelo lokuchoboza luyingxenye ebalulekile yenqubo yokujova amalahle aqothulwe ngesithando somlilo, kanti ukucubungula i-roller mill eqondile, amalahle aqothulwe esithando kuyinqubo eyinhloko yesistimu yokuchoboza. Ukulungiswa kwamalahle aqothulwe ngokucubungula i-roller mill eqondile kubhekisela ekucutshungulweni kwamalahle aluhlaza abe amalahle aqothulwe anobukhulu bezinhlayiya kanye nokuqukethwe kwamanzi okuhlangabezana nezidingo zokujova i-blast mill nge-vertical coal mill ngaphansi kwezimo zomnotho ezivunyelwe. Uhlelo lokuchoboza lwakhiwe kakhulu ngokuphakela, ukomisa nokugaya, ukuqoqwa kwempuphu kanye nokususwa kothuli. Ekuchobozeni amalahle nge-bituminous, ukucindezela okuhambisanayo okuvimbela ukuqhuma kanye namadivayisi okuqapha nokulawula ahambisanayo kumele futhi kusethwe. Inqubo yokucubungula umshini wokugaya ojikelezayo oqondile ngamalahle acoliwe: amalahle aluhlaza athunyelwa phakathi kwe-turntable ngepayipi lokuwa kwamalahle, futhi amandla e-centrifugal akhiqizwa ukujikeleza kwe-turntable enza amalahle aqhubekele phambili emaphethelweni e-turntable, futhi amalahle ayachotshozwa lapho edlula ngaphansi kwama-roller. Kufakwa indandatho yezindandatho ezivimbayo emaphethelweni e-turntable, engavimbela amalahle ukuthi ashelele ngqo e-turntable. Ngemva kokuba umoya owomile ungeniswe ekamelweni lomoya usuka emgudwini womoya, ungena engxenyeni engenhla ye-turntable nge-annular air duct ezungeze i-turntable ngesivinini esingaphezu kwama-35m/s. Ngenxa yomphumela wokungena komoya, amalahle acoliwe alethwa ku-coarse powder separator ku-coarse powder mill. Kukhona futhi indilinga yama-blades ajikeleza ne-turntable ezungeze i-turntable. Umsebenzi we-blade ukuphazamisa ukuhamba komoya, ukuze i-coarse coal powder separator engxenyeni engenhla yomshini wokugaya amalahle.

Yiziphi izinzuzo zobuchwepheshe zokucubungula i-vertical roller mill amalahle acoliwe? Ngokwejubane le-coal mill, ingahlukaniswa ibe yi-low speed coal grinding mill kanye ne-medium speed coal mill. I-low speed coal mill ibizwa nangokuthi i-steel ball mill noma i-ball mill, kanti ijubane lesilinda lingu-16.～25r/min. Umshini wokugaya amalahle oqondile uwumshini wokugaya amalahle osheshayo esimaphakathi onesivinini esijikelezayo esingu-50-300 r/min.I-roller mill eqondile ingcono kune-steel ball mill ekucubunguleni amalahle acoliwe, futhi iyi-rotary coarse mill esetshenziswa kabanzi ohlelweni olusha lokugaya okwamanje. Inqubo yokucubungula amalahle acoliwe nge-roller mill eqondile inezinzuzo zesakhiwo esiqinile, isikhala esincane sephansi, ukutshalwa kwezimali okuphansi, umsindo ophansi, ukusetshenziswa kwamanzi okuphansi, ukusetshenziswa kwensimbi okuphansi kanye nokusetshenziswa kwamandla okugaya amalahle okuphansi. Ukusetshenziswa kwamandla kwe-roller mill eqondile yokucubungula amalahle acoliwe ngokusobala kuncishisiwe ngesikhathi sokusebenza komthwalo ophansi, futhi ukusetshenziswa kwamandla ngeyunithi ngayinye yamalahle acoliwe akukhuphuki kakhulu. Lapho kusetshenziswa i-rotary coarse powder separator, amalahle acoliwe anokulingana okuhle kanye ne-high uniformity index.

I-HCMilling (Guilin Hongcheng), njengomkhiqizi weokucoliwe amalahleukugayaumshini wokugaya, inezikebhe zamakhasimende ezicebile kanye nolwazi oluvuthiwe lobuchwepheshe ekucutshungulweni kwe-vertical roller mill yamalahle acoliwe, okunikeza ukwesekwa okuqinile kwemishini kumakhasimende e-vertical roller mill processing namalahle acoliwe. Uma unezidingo ze-pulverized coal vertical roller mill, sicela u-cxhumana nathiukuthola imininingwanefuthi usinikeze ulwazi olulandelayo:
