Isiphetho: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.

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

Ukubekezela, amandla okusebenza, ukwahlukaniswa kanye nezifo zesakhiwo zensimbi engenayo zichaza ubunzima bokuqhumisa. Uma ukukhuliswa kungenalutho, insimbi engenayo ilula ukuyiqhumisa, ukushabalala kweplate ye-lining kanye nezinto ezinkulu zokuqhumisa ze-ball mill kuphansi, futhi nokusetshenziswa kwamandla kuphansi; ngaphandle kwalokho, ukushabalala nokusetshenziswa kwamandla kuzobe kubalulekile. Imfashini yensimbi engenayo ichaza ngqo ukukhiqizwa 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. “Ukuthutha okuningi futhi ukucisha okuncane”, kunciphisa usayizi wama-particle wokudla lwe-ore

Usayizi omkhulu wama-particle wokucisha, amandla amaningi i-ball mill ayadinga ukwenza ku-ore. Ukuze kufinyelelwe ukucisheka okudingwayo, umsebenzi we-ball mill uzoqiniswa ngokuqinisekile.

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

Ekusebenzeni kwangempela, inqujwayo yokucisha ingaqeqeshiswa ngokuvumelana nezici zemifino yomthombo, njengekhulukazi lokukhulukazi kweziminerali ezinhle, izinga lokwahlukaniswa kwemola, kanye nokukhulukazi kweziminerali ezingalungile. Imisebenzi efana nokukhishwa kwemikhahla yangaphambili, ukwandiswa kwemikhahla yangaphambili, ukucisha ngezindlela ezahlukene, ukwahlukaniswa kwangaphambili, nezokusebenza ezinye zingasetshenziswa ukuqeqeshisa isikhungo sokubhula, okuhambisana nokunciphiselwa kwenani lokucisha, kanye nokuphinda kuphinde kuvuselelwe iminerali ezinhle 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.

Ishubhu sokubuyisa isihlabathi siyisilinganiso sokubuyiswa kwesihlabathi sebhola umshini kumthamo wezinsalela, futhi usayizi wayo uthinta ngqo ukukhiqizwa kwebhola umshini. Enye indlela yokwenza ngcono ishubhu sokubuyisa isihlabathi sesitshalo sokugqoka ukwengeza umthamo wezinsalela zokuqala, kanti enye indlela iwukunciphisa ukuphakama kwe-shaft ye-classifier ehlanganayo.

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

Ngokwemithetho yezindaba zasemzini, ukulawulwa ozenzakalelayo kwesixhumi sokugaya nokulinganisela kungakhweza inani lokukhiqiza ngo-2.5% kuya ku-10%, futhi ukusetshenziswa kwamandla kungasindiswa nge-0.4 kuya ku-1.4kWh/t lapho kususwa itoni 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.
