Ngenxa yokuntuleka kwamandla emhlabeni, ukusetshenziswa kwamandla enkambisweni yokuchoboza kuye kwadonsela ukunaka okukhulu. Kusukela kwafika umshini wokugoqa ocindezela kakhulu ngasekupheleni kwawo-1980, ubulokhu usetshenziswa kakhulu embonini yesimende kanye nasezimayini zensimbi ezingezona ezensimbi ngazinye. Imboni yesimende izuze kule mishini esebenza kahle kakhulu esindisa amandla kanye nokusetshenziswa kwensimbi.
Inani lama-ore aqoshiwe ekusetshenzisweni kwensimbi nasekumbiweni likhulu kakhulu, futhi iningi lama-ore ensimbi lilukhuni futhi kunzima ukuwagaya. Njengamanje, izinkinga zokusetshenziswa kwamandla, ukusetshenziswa kwensimbi kanye nokusebenza kahle kwama-ball mills zivelele kakhulu, futhi izinga lokubuyiselwa kwamaminerali nalo lithinteka kakhulu yindlela yokugaya. I-roller mill enomfutho ophezulu isetshenziswa kabanzi embonini yensimbi kanye neyokumbiwa, futhi isezingeni eliphambili emhlabeni. Kungumphumela wokuhlola okuqhubekayo kanye nomkhuba wabakhiqizi bemishini yasekhaya eminyakeni yamuva, kanye nempumelelo yokugcina.

Umehluko phakathi kwemishini yokugoqa enomfutho ophezulu kanye nemishini yokuchoboza yendabuko
I-roller mill enomfutho ophezulu ifana kakhulu ngesimo sayo ne-double roller crusher yendabuko, kodwa kunezinhlobo ezimbili zomehluko.
Esinye ukuthi umshini wokugoqa ocindezela kakhulu usebenzisa ukuchoboza okungaguquki, okusindisa cishe u-30% wamandla okusetshenziswa uma kuqhathaniswa nokuchoboza okunamandla;
Okwesibili, isebenzisa ukuchoboza ungqimba lwezinto zokwakha, okuwukuchoboza okuhambisanayo phakathi kwezinto zokwakha nezinto zokwakha, ngokusebenza kahle kokuchoboza okuphezulu, kanye nokucindezeleka kokukhipha izinto phakathi kwezinto kungalungiswa ngokucindezela kwe-roller. Ama-roller amabili ajikeleza ebhekene, elinye liyi-roller eqondile kanti elinye liyibanga elilungisekayo. Ukucindezela phakathi kwama-roller ngokuvamile kungafinyelela emoyeni ongu-1500 kuya ku-3000, kanti imikhiqizo echobozekile ingafinyelela ku-2mm, okwenza "kuchobozeke kakhulu futhi kunciphe ukugaya" futhi kube uhlobo olusha lwemishini yokuchoboza ethatha indawo yokugaya ngokuchoboza. Ngenxa yamandla ayo amakhulu, ayigcini nje ngokuchoboza izinto, kodwa futhi iphula isakhiwo sangaphakathi sezinhlayiya zezinto zokwakha, ngaleyo ndlela ithuthukise kakhulu amandla okugaya.
I-roller mill enomfutho ophezulu yakhiwe ngedivayisi yokondla kagesi, idivayisi yokuvimba izinto, idivayisi yokushayela, idivayisi yokulayisha i-hydraulic, idivayisi esekelayo, izingxenye ze-roller ezinamandla nezinganyakazi, njll.

Ukugeleza kwenqubo ejwayelekile yesigayo se-roller esinomfutho ophezulu ekuzuzeni
1. Inqubo yokuphonsa umsila omanzi ogcwele okusanhlamvu okuvaliwe
Enkambisweni yokusebenzisa lo mshini ukucubungula i-ore, ukuphonswa komsila omanzi kwe-coarse-grained closed-circuit roller milling kuyinqubo evamile. Isithombe esilandelayo sibonisa ukugeleza kwenqubo eyinhloko:
Ishadi lokugeleza kwenqubo yokuphonsa umsila omanzi okusanhlamvu okuqinile
Ekusetshenzisweni okuqondile kwale nqubo, ikhekhe elinobuthi livivinywa kakhulu ngesekethe evaliwe, ukuze usayizi wezinhlayiya zomkhiqizo ocutshungulwa yi-roller mill enomfutho ophezulu uhlale ulawulwa ngaphakathi kobubanzi obufanele kakhulu ukuhlunga nokufaka umsila, futhi ekugcineni kufezwe injongo yokuphonsa umsila kusengaphambili.
1. Inqubo yokugaya ibhola eliyingxenye yesigayo se-closed-circuit roller mill
Ngezindlela eziningi zokukhiqiza kanye nokuhlolwa okuhlobene, kutholakale ukuthi imikhiqizo ye-ore etholwe yi-high-pressure roller mill ayinayo nje kuphela usayizi wezinhlayiya ezincane, kodwa futhi ifinyelela ukwanda okukhulu kokuqukethwe kwempuphu yamaminerali. Phakathi kwazo, okuqukethwe kwezinto ezingaphakathi kuka-0.2mm kungafinyelela ku-30%-40%, izinto zaleli zinga lokucwebezela zingahlangabezana nezidingo zokuhlunga i-ore ezimweni eziningi, ngakho-ke kulolu hlobo lomkhiqizo, umsebenzi wokuhlunga ungenziwa ngqo ngemuva kokuwuhlukanisa.
Ngesikhathi esifanayo, enkambisweni yokusebenzisa umshini wokugaya ocindezela kakhulu ukuhluza i-ore kanye nokukhiqizwa kokuchoboza i-ore, ngaphansi kwesenzo somphumela wezinto eziseceleni, kuzoba nengxenye encane yezinhlayiya ze-ore ezinobukhulu bezinhlayiya obukhulu ngaphakathi kwekhekhe lokuphuma. Uma le ngxenye isetshenziswa ngqo Ngesikhathi sokusebenza kokugaya noma kokuhlanza, ukuhamba komsebenzi okuhambisanayo kuzoshintshashintsha kakhulu, okuzoletha izinga elithile lomthelela omubi ekukhiqizweni kokuhlanza.
Ngakho-ke, enkambisweni yokukhiqizwa kwe-ore ngemishini yemishini, ukuze kugwenywe izinkinga ezinjalo, kubalulekile ukwenza ukuhlolwa kokujikeleza kwe-closed-circuit kwekhekhe lezinto ngemuva kokucutshungulwa kwe-extrusion yi-roller mill enengcindezi ephezulu. Ngale ndlela, usayizi wezinhlayiya zomkhiqizo ekhekheni ungalawulwa ngokuqinile ukuvimbela ukuguquguquka kwenqubo okubangelwa ukungena kwe-ore enosayizi wezinhlayiya omkhulu kakhulu ekusebenzeni kokugaya ibhola. Futhi kuyenze ngqo enkambisweni yokukhetha. Indlela enjalo ayikwazi nje ukufeza ukwehla okukhulu kwenani lokudla kwe-ore enkambisweni yokugaya ibhola, kodwa futhi igweme ngempumelelo ukugaya ngokweqile kwe-ore enezinhlamvu ezincane, ngaleyo ndlela kuthuthukiswe ngokuphelele ukusebenza kahle kanye nekhwalithi yokugcoba.
3 Ezinye izinhlobo zenqubo ejwayelekile yokugeleza kwenqubo
Ngaphezu kwezinqubo ezimbili ezisetshenziswa kakhulu ezingenhla, kunezinye izinqubo eziningana ezivamile ezivamile enqubweni yokuchoboza nokukhiqiza ama-ore okusizakala ngama-roller mills. Enye iwukugaya ibhola le-roller mill elivulekile ngesimo sobuciko beklasi yobukhulu bezinhlayiya ezigcwele.
Ishadi lokugeleza kwenqubo yokugaya ibhola le-roller mill elivulekile
Enye inqubo yokugaya ibhola ngendlela yokujikeleza kwezinto ezigoqekayo. Okulandelayo ishadi layo eliyinhloko lokugeleza kwenqubo:
