Ukusebenza kahle kokugaya kwebhola lebhola kuthinteka yizici eziningi, phakathi kwazo okuyinhloko: ifomu lokunyakaza kwebhola lensimbi ku-cylinder, isivinini sokujikeleza, ukungezwa nobukhulu bebhola lensimbi, izinga lezinto ezibonakalayo. , ukukhethwa komugqa kanye nokusetshenziswa kwe-ejenti yokugaya. Lezi zici zinomthelela ekusebenzeni kahle kwesigayo sebhola ngezinga elithile.
Ngokwezinga elithile, ukuma kokunyakaza kwendawo yokugaya kusilinda kuthinta ukusebenza kahle kokugaya ibhola. Indawo yokusebenza yomshini wokugaya ibhola ihlukaniswe ngezigaba ezilandelayo:
(1) Endaweni yokunyakaza ezungezile newayo, inani lokugcwalisa kusilinda lincane noma alikho, ukuze impahla ikwazi ukwenza ukunyakaza okuyindilinga okufanayo noma ukunyakaza okuwayo kusilinda, kanye nethuba lomthelela webhola lensimbi nensimbi. ibhola liba likhulu, libangele ukuguga phakathi kwebhola lensimbi kanye ne-liner, okwenza umshini wokugaya ungasebenzi kahle;
(2) Yehlisa indawo yokunyakaza, ugcwalise inani elifanele. Ngalesi sikhathi, ibhola lensimbi linomthelela ezintweni, okwenza ukusebenza kahle kwesigayo sebhola kuphakeme kakhulu;
(3) Endaweni ezungeze indawo ephakathi nendawo yokugaya ibhola, ukunyakaza okuyisiyingi kwebhola lensimbi noma ukuxubana kokuwa nokujikijela kwenza ukunyakaza kwebhola lensimbi kube nomkhawulo, futhi ukuguga nomthelela kuncane;
(4) Endaweni engenalutho, ibhola lensimbi alinyakazi, uma inani lokugcwalisa likhulu kakhulu, uhla lokunyakaza kwebhola lensimbi lincane noma alihambi, khona-ke lizobangela ukuchithwa kwezinsiza, kulula ukwenza isigayo sebhola. ukwehluleka.
Kungabonakala kusuka ku-(1) ukuthi uma inani lokugcwalisa lincane kakhulu noma lingekho, umshini webhola ulahlekelwa ukulahlekelwa okukhulu, okubangelwa ikakhulukazi umthelela webhola lensimbi ezintweni. Manje umshini jikelele webhola uvundlile, ukuze unciphise ngempumelelo ukulahlekelwa kwesigayo sebhola kungabi nalutho, kukhona isigayo sebhola esiqondile.
Emishinini yokugaya ibhola yendabuko, isilinda somshini wokugaya ibhola siyazungeza, kuyilapho isilinda semishini yokuxuba simile, encike kakhulu emshinini wokuxuba ovunguzayo ukuze iphazamise futhi inyakazise ibhola lensimbi nezinto ezisemgqonyeni. Ibhola nezinto ezisetshenziswayo zijikeleza kumishini ngaphansi kwesenzo sedivayisi yokuxuba eqondile, ukuze izinto ezibonakalayo zisebenze kuphela ebholeni lensimbi kuze kube yilapho ichotshozwa. Ngakho-ke ifaneleka kakhulu ekusebenzeni kahle kokugaya kanye nokusebenza kahle kokugaya.
I-02 Isivinini Ipharamitha ebalulekile yokusebenza yomshini webhola yijubane, futhi le pharamitha yokusebenza ithinta ngokuqondile ukusebenza kahle kokugaya ibhola. Uma ucabangela izinga lokujikeleza, izinga lokugcwalisa kufanele licatshangelwe. Izinga lokugcwalisa lihlotshaniswa kahle nezinga lokuzungezisa. Gcina izinga lokugcwalisa lingashintshi lapho uxoxa ngezinga lokuphenduka lapha. Kungakhathaliseki ukuthi isimo sokunyakaza kwenkokhelo yebhola siyini, kuzoba nezinga lokujikeleza elifaneleka kakhulu ngaphansi kwenani elithile lokugcwalisa. Uma izinga lokugcwalisa lilungisiwe futhi izinga lokuzungeza liphansi, amandla atholwe yibhola lensimbi aphansi, futhi amandla omthelela ezintweni aphansi, angase abe ngaphansi kunevelu yomkhawulo wokuchotshozwa kwe-ore futhi kubangele umthelela ongasebenzi ku-ore. izinhlayiya, okungukuthi, izinhlayiya ze-ore ngeke ziphuke, ngakho-ke ukusebenza kahle kokugaya kwejubane eliphansi kuphansi. Ngokukhula kwesivinini, amandla omthelela webhola lensimbi anomthelela obonakalayo ayanda, ngaleyo ndlela andise izinga lokuchotshozwa kwezinhlayiya ze-ore emahhadla, bese kuthuthukisa ukusebenza kahle kokugaya kwebhola. Uma isivinini siqhubeka sanda, lapho siseduze nesivinini esibucayi, imikhiqizo yokusanhlamvu e-coarse akulula ukuphulwa, lokhu kungenxa yokuthi ngemva kwejubane eliphezulu kakhulu, nakuba umthelela webhola lensimbi ungandiswa, kodwa inani lemijikelezo. webhola lensimbi lehle kakhulu, inani lomthelela webhola lensimbi ngesikhathi seyunithi lehlile, futhi izinga lokuchotshozwa kwezinhlayiya ze-ore emahhadla lehla.
03 Ukwengezwa nosayizi wamabhola ensimbi
Uma inani lamabhola ensimbi angeziwe alifanelekile, ububanzi bebhola kanye nesilinganiso akufanelekile, khona-ke kuzoholela ekunciphiseni ukusebenza kahle kokugaya. Ukugqokwa komshini wokugaya ibhola ekusebenzeni kukhulu, futhi ingxenye enkulu yesizathu ukuthi ibhola lensimbi yokufakelwa alilawulwa kahle, okuholela ekuqoqweni kwebhola lensimbi kanye nesimo sokunamathela kwebhola, bese likhiqiza. ukugqoka okuthile emshinini. Njengomshini oyinhloko wokugaya webhola lokugaya, kuyadingeka ukulawula hhayi kuphela inani lebhola lensimbi elingeziwe kodwa nesilinganiso salo. Ukwenziwa kahle kwendawo yokugaya kungakhuphula ukusebenza kahle kokugaya cishe ngama-30%. Enqubweni yokugaya, ukugqokwa komthelela kukhulu futhi ukugqokwa kokugaya kuncane lapho ububanzi bebhola bukhulu. Ububanzi bebhola buncane, ukugqoka komthelela kuncane, ukugqoka kokugaya kukhulu. Uma ububanzi bebhola bukhulu kakhulu, inani lemithwalo ku-cylinder liyancipha, indawo yokugaya yomthwalo webhola incane, futhi ukugqoka kwe-liner kanye nokusetshenziswa kwebhola kuzokwandiswa. Uma ububanzi bebhola buncane kakhulu, umphumela wokunciphisa wezinto ezibonakalayo uyakhula, futhi umphumela wokugaya umthelela uzoba buthaka.
Ukuze kuthuthukiswe ukusebenza kahle kokugaya, abanye abantu babeka phambili indlela enembile yebhola yokwenza:
(l) Ukuhlaziywa kwesisefo kwama-ore athile bese uwahlanganisa ngosayizi wezinhlayiyana;
(2) Ukumelana nokugaywa kwensimbi kuyahlaziywa, futhi ububanzi bebhola obudingwa yiqembu ngalinye lezinhlayiya zensimbi bubalwa ngefomula ye-semi-theoretical yebhola ububanzi;
(3) Ngokwezici zokubunjwa kosayizi wezinhlayiya zento okufanele igaywe, isimiso sokuchoboza i-statistical mechanics sisetshenziswa ukuqondisa ukwakheka kwebhola, futhi isilinganiso samabhola ensimbi ahlukahlukene senziwa ngomgomo wokuthola ubuningi. amathuba okuchoboza;
4) Ibhola libalwa ngesisekelo sokubala kwebhola, futhi izinhlobo zamabhola ziyancishiswa futhi izinhlobo ezi-2 ~ 3 zengezwe.
04 Izinga lezinto ezibonakalayo
Izinga lezinto ezibonakalayo lithinta izinga lokugcwalisa, elizothinta umphumela wokugaya webhola lebhola. Uma izinga lempahla liphezulu kakhulu, lizobangela ukuvinjwa kwamalahle kumshini wokugaya ibhola. Ngakho-ke, ukuqapha ngempumelelo izinga lezinto ezibonakalayo kubaluleke kakhulu. Ngesikhathi esifanayo, ukusetshenziswa kwamandla omshini wokugaya ibhola kuhlobene nezinga lezinto ezibonakalayo. Ohlelweni olumaphakathi lokugaywa kwesitoreji, ukusetshenziswa kwamandla omshini wokugaywa kwebhola kubala cishe u-70% wokusetshenziswa kwamandla ohlelo lokuhlikihla futhi cishe u-15% wokusetshenziswa kwamandla kwesitshalo. Kunezici eziningi ezithinta isistimu ye-pulverization yesitoreji esimaphakathi, kodwa ngaphansi kwethonya lezici eziningi, ukuhlolwa okuphumelelayo kwezinga lempahla kuyadingeka kakhulu.
05 Khetha i-liner
I-lining plate ye-ball mill ayikwazi nje ukunciphisa umonakalo we-cylinder, kodwa futhi idlulisele amandla endaweni yokugaya. Esinye sezici ezithinta ukusebenza kahle kokugaya kwebhola kunqunywa indawo yokusebenza ye-liner. Ekusebenzeni, kuyaziwa ukuthi ukuze kuncishiswe ukulimala kwesilinda futhi kuthuthukiswe ukusebenza kahle kokugaya, kuyadingeka ukunciphisa ukushelela phakathi kwendawo yokugaya kanye ne-liner, ngakho-ke ukusetshenziswa okuyinhloko ukuguqula ukwakheka kwendawo yokusebenza ye-liner nokwandisa i-coefficient ye-friction phakathi kwe-liner nendawo yokugaya. I-high manganese steel liner yayisetshenziswa ngaphambili, futhi manje kune-raber liner, i-magnetic liner, i-angular spiral liner, njalonjalo. Lawa mabhodi oqweqwe olulungisiwe awagcini nje ngokudlula amabhodi ensimbi ensimbi ye-manganese aphezulu ekusebenzeni, kodwa futhi anganweba ngempumelelo impilo yesevisi yomshini wokugaya ibhola. Ukusebenza kahle kokugaya kungathuthukiswa ngokuphumelelayo ngokuthuthukisa isimo sokunyakaza, izinga lokuguqula, ukungeza kanye nosayizi webhola lensimbi, izinga lempahla kanye nekhwalithi yempahla ye-lining ye-ball Mill.
