Summary: Ukusebenza okuphansi kokugaya, ikhono eliphansi lokucubungula, ukusetshenziswa kwamandla okuphezulu ekuveliseni, nokungazinzi kobukhulu bemikhiqizo yeball mill yizinselele ezivame ukubhekana nazo abasebenzisi abaningi embonini. Indlela yokuthuthukisa ukusebenza kahle kokugaya kweball mill ngendlela ephumelelayo iyindaba ebalulekile....

Ukwehliswa okuncane kokuhlafuna, amakhono amancane okuqeqeshwa, ukusetshenziswa okukhulu kwamandla okuvelisa, kanye nokwakheka okungenalungelo kwemiphumela yokuqeqeshwa kwe-ball mill yizinkinga eziningi abasebenzisi emkhakheni abazohlangana nazo. Indlela yokuthuthukisa ngokusebenza kwe-ball mill yokuhlafuna kuyinkinga ebalulekile.

Nansi indlela eyi-10 yokuthuthukisa ukusebenza kwe-ball mill yokuhlafuna.

ball mill

1. Shintshintsha ukukhuliswa kwemvelo yensimbi engenayo

Ubunzima, ukuqina, ukuhlukaniswa kanye nokungcolakala kwesihlabathi esiyisikhutha kuncike ebunzimeni bokugaya. Uma ukugaya kuthambekele ukuphansi, isihlabathi sikulula ukugaya, ukuwohloka kwephepha lesigubhu kanye amabhola okugaya kwe-ball mill kuba kuncane, kanye nokusetshenziswa kwamandla nakho kuyaphansi; kwakho-ke, ukuwohloka nokusetshenziswa kwamandla kuzoba phezulu. Isici sesihlabathi esiyisikhutha sithonya ngqo ukusebenza kahle kwe-ball mill.

Ekuthuthukisweni, uma insimbi engenayo inzima ukuyiqhumisa noma imikhiqizo efunwa iyinhle, kungase kuqatshelwe ukusebenzisa inqubo entsha yokwelapha

  • Indlela eyodwa iwukwengeza izinto ezithile zekhemikhali ngesikhathi sokucisha ukuze kuthuthukiswe umphumela wokucisha nokwandisa ukusebenza kokucisha;
  • Indlela yesibili iwukushintsha ukucishekayo kwe-ore, isibonelo, ukushisa uminerali ngamunye ku-ore, ukushintsha izimfanelo zekhulu zomgubo we-ore, ukunciphisa ubukhulu, njll.

2. "Okunophehla kakhulu nokunciphisa kancane", Yehlisa ubukhulu bemvelo yomkhiqizo wezinsimbi ezifuthwayo zokugaya.

Njengoba usayizi wamaqanda okugeza emzimbeni omkhulu, amandla needed i-ball mill kufanele ilele ngokukhulu, ukugeza impahla yegolide. Ukuze kufezwe ubukhulu obudingekayo, umsebenzi we-ball mill uye wena, futhi ngokulandelanayo, ukukhipha amandla nakho kuzokhula.

Ukuze kunciphisa ukhulu lokhulu lwempahla yokukhuliswa kwempahla, kudingeka ukuba ukhulu lwempahla ephulelwe lube lukhulu, okungukuthi, "ukukhuliswa okuningi futhi ukukhuliswa okuncane". Ngaphezu kwalokho, ukusebenza kahle kwenqubo yokukhuliswa kuyaphezulu kakhulu kunenqubo yokukhuliswa, futhi ukusetshenziswa kwamandla kwenqubo yokukhuliswa kuyancane, cishe ku-12% kuya ku-25% kokusetshenziswa kwamandla kwenqubo yokukhuliswa.

3. Ukuhluzwa okuhle kwesilinganiso sezitsha zeqhwa

Phansi kwesimo lapho i-ball mill iqhuba ngesivinini esithile futhi isivinini sokugcwalisa sihle, izitsha zeqhwa zensimbi ziyoshintshana nempahla izihlandlo eziningi,

Namanje, imigodi eminingi ibekela isivinini sokuqala phakathi kwe-45% kuya ku-50%. Kodwa isivinini sokuqala esiyimfuneko kufanele sicaciswe ngokuvumelana nesimo, ngoba isimo somsebenzi wezinto ezihlanganisiwe zohlelo ngalunye luhlukene, ukukopisha idatha yabanye abantu yokuthuthukisa izinsimbi ngeke kufeze umphumela wokukhukhumalisa ofunekayo.

4. Ubukhulu nokuhlukaniswa okufanele kwezinsimbi zeqhwa

Njengoba izinsimbi zeqhwa emilinini ye-ball lithinta izinsimbi ezithinta okhokho, uma i-diameter yezinsimbi zeqhwa ikhulu kakhulu, amandla okucindezela nalo ayoba amakhulu, okwenza izinsimbi zicindezelwe ngendlela yokuthinta amandla endlela yokuthinta amandla esikhulu kunendlela yokuthulula ngaphandle kwesikhuluva.

Ngaphezu kwalokho, uma izinga lokugcwalisa leziqithi zethusi lingafanayo, isikali esikhulu kakhulu sezinhlamvu zenza kube nezinhlamvu ezimbalwa zethusi, ukumaneka okuncane kokuqhuma, isimo esibi sokuqhumisa okungaphezu kwesilinganiso, kanye nobukhulu bemicu yemveliso okungalingani. Uma isiqithi sethusi singancinyane, amandla okuqhumisa emgodini amancane, futhi ukusebenza kokukhwama kulukhulu. Ngakho-ke, ubukhulu beqithi lethusi nolwimi lwaso kulalokhu kubalulekile kakhulu ekusebenzeni kokukhwama.

5. Faka ngokunembile iziqithi zethusi

Ekuthuthukisweni, umsebenzi wokukhwama weziqithi zethusi nomgodini kuzoba yimphawu yokulahleka kweziqithi zethusi, okukhohlisa ukuguqulwa komlinganiselo weziqithi zethusi.

6. Ukuhlanganiswa okufanele kwe-grinding

Ukuhlanganiswa kwe-grinding kuhilela umthamo ozimele (specific gravity) wamanzi ashiqiswe, izinga lokubambezeleka kwama-ore emgodini kuzungezile amabhola esihambi, nokuqina kwamanzi ashiqiswe.

Uma ukuhlanganiswa kwe-grinding kungaphansi, ukuxhumana kwamanzi ashiqiswe kuyashesha, futhi izinga lokubambezeleka kwempahla kuzungezile amabhola esihambi kungaphansi, okwenza ukweqisa kanye nokuqhalaliswa kwamanzi ashiqiswe amabhola esihambi empahla kube buthakathaka, ubukhulu bempahla ephumayo bungafaneleki, futhi amandla okusebenza kwe-grinding angasebenzi kahle;

Ukuhlonyeliswa kokucisha kuyakhulu, ukubambezelana kwempahla emgqobhozeni yeziqeshana zethusi kungcono, futhi imiphumela yokuthinta nokuhlonyela kweziqeshana zethusi empahla iyinhle, kodwa ukusabalalisa kwamanzi okuhlonyelayo kusele, okwenza kube lula ukuthi impahla iphule kakhulu, okungavumeli ukuthi kukhuliswe amakhono okusebenza kwemilili yezibhola.

Ekusebenzeni, uhlonyelo kokucisha njalo kulondolozwa ngokulawula inani lensimbi ehlinzekwa emilini, noma inani lamanzi ahlinzekwayo emilini, noma ngokuhleleka kabusha kwemisebenzi yokulinganisa, nokulungisa inani lolwimi lwezinhlayiya kanye nokuhlangana kwamanzi

7. Qeqeshisa inqujwayo yokucisha

Ekukhiqizweni okwenziwa ngempela, inqubo yokuwasha ingathuthukiswa ngokuya ngezimpawu zegolide eliyinhloko, njengosayizi weqaza elihlanganisiwe lamaminerali asebenzayo, izinga lokwehlukaniswa komuntu ngamunye, kanye nosayizi weqaza elihlanganisiwe lamaminerali amasela. Operations ezifana nokwenziwa ngaphambi kokusula, ukuchachazwa kwangaphambili, ukugaya kwesigaba, ukukhethwa kwangaphambili kanye neminye imisebenzi zingamukelwa ukunciphisa uhlelo lokuwasha, okungenye indlela, kunganciphisa inani lokuwasha, ngakolunye uhlangothi, futhi kungabuyisela amaminerali abayigugu ngesikhathi.

8. Ukhuthazwa kokusebenza kweqembu lokucacisa

Umthelela wokusebenza kweqembu lokucacisa ekuthuthukiseni kokusebenza kokugaya uqondile. Ukusebenza okuphezulu kweqembu lokucacisa kusho ukuthi izicucu ezifanele zingasikelelwa ngesikhathi esifanele nangendlela efanele, kuyilapho ukusebenza okuncane kweqembu lokucacisa kusho ukuthi iningi lezicucu ezifanele azisikelelwa futhi zibuyiselwa emlilweni wokugaya, okuyinto elula yokuba kube nomphumela wokugaya okungaphezulu, ngalokho kubangela ukubangela umphumela olukhulu lokucacisa kamuva.

Ukusebenza kweqembu lokucacisa kungathuthukiswa ngokusebenzisa i-classification yesigaba sesibili noma ngokuthuthukiswa kwezinto zokucacisa.

Khuthaza ngokufanele ukubuyiselwa kwezinto zokwakha zomdaka ezintsha.

Isilinganiso sokubuyiselwa kwesihlabathi yisilinganiso semali yokubuyiselwa kwesihlabathi esivela ebhodini lebhola kumthamo wokufaka ubuchwepheshe obuvamile bempahla esemqoka, futhi usayizi wawo ugcina uthinta ngqo ukukhiqiza kwe-bola. Enye indlela yokuthuthukisa isilinganiso sokubuyiselwa kwesihlabathi kwindawo yokuhlanza izimayini ukufaka kabusha inani lokufaka ishidi lomsebenzi wokuqala, futhi enye indlela ukunciphisa ukuphakama komkhakha we-spiral classifier.

Nokho, ukukhula kwesilinganiso sokubuyiselwa kwesihlabathi kunesilinganiso esithile. Uma kwenyuka kuya kwesilinganiso esithile, ukukhula kokusebenza komshini wokucisha amabili kuncane kakhulu, futhi ukudlaywa kwe-ore yonke emishinini yokucisha kuqonde kwesikhulu sokusebenza komshini wokucisha, okusho ukuthi kulula ukuveza ukukhubaza, ngakho-ke izinga lokubuyisela lesihlabathi akufanele libe likhulu kakhulu.

10. Ulawulo oluzenzakalelayo lwesistimu yokucisha

Kukhona izinto eziningi ezihlukahlukene ekusebenzeni kokucisha, futhi ukushintshwa okukodwa kuzoqikelela ukushintshwa okuqhubekayo kwama-parameter amaningi. Uma kusetshenziswa ukusebenza ngesandla, imveliso

NgokweziZulu-zizwe zangaphandle, ukulawulwa ngokuzenzakalelayo kwezindaba zokugaya nokuhlukanisa kungakhuphula amandla okukhiqiza ngo-2.5%~10%, futhi ukusetshenziswa ngamandla kungagcina u-0.4~1.4 kWh/t uma kucutshungulwa ithoni eyodwa ye-ore.

Ekusetshenzisweni kokugaya, kukhona izinto eziningi eziholela ekunciphiseni kwesixhumi sokugaya. Izinto eziningi zingalawulwa futhi ziqondwe ngokwengqondo kuphela, futhi kuyingozi ukuzihlaziyela ngokulinganisela. Thola izindlela ezingasebenza emikhakheni ehlukahlukene ukuze uqondanise ukukhiqizwa endaweni yokusebenza, ukuze kunciphiseswe izindlela zokukhiqiza futhi kufezeke injongo yokusindisa amandla nokunciphisa ukusetshenziswa kwakho.
