Indima ye-HPGR ekuQhutyweni ngokuLungileyo kuMandla

Intshayelelo:

I-Comminution, inkqubo yokunciphisa ubungakanani be-ore particles, idlala indima ebalulekileyo kwimisebenzi yokucubungula izimbiwa. Ngokwemveli, le nkqubo iqhutywe kusetyenziswa iindlela zokusebenzisa amandla amakhulu ezifana ne-ball milling kunye ne-SAG (Semi-Autogenous Grinding). Nangona kunjalo, ngokufika kobuchwephesha be-High Pressure Grinding Rolls (HPGR), kubekho utshintsho olubalulekileyo olubhekiselele kusetyenziso olusebenza ngamandla. Eli nqaku liphonononga indima ye-HPGR ekusebenziseni amandla ngokufanelekileyo kunye nefuthe layo kwishishini lemigodi.

1. UkuSebenza ngokuSebenza koMbane:

Imisebenzi yokudibanisa idla isixa esikhulu samandla kwimizi-mveliso yokulungiswa kwezimbiwa. Kuqikelelwa ukuba ukuya kuthi ga kwi-4% yokusetyenziswa kwamandla ehlabathi kubalelwa kukuhamba. Ke ngoko, ukuphucula ukusebenza kakuhle kwamandla ekunxibelelaneni kube yinto ephambili kuzo zombini izizathu zokusingqongileyo kunye nezoqoqosho.

2. Imiqulu yokuSila ngoxinzelelo oluphezulu (HPGR):

Itekhnoloji ye-HPGR ibonelela ngesisombululo esithembisayo sokusebenzisa amandla ngokufanelekileyo. Oomatshini be-HPGR banemiqulu emibini ejikajikayo, edla ngokwenziwa ngentsimbi, phakathi apho amasuntswana e-ore atyiswa khona. Ngokusebenzisa uxinzelelo oluphezulu kwizinto zokutya, ii-HPGRs zifezekisa ukuphuka ngokugqithiseleyo ngokuxinwa kwe-inter-particle, kunokuba impembelelo okanye i-attrition.

3. Iinzuzo ze-HPGR ekuSebenzeni ngokuSebenza koMbane:

Enye yeenzuzo eziphambili zeteknoloji ye-HPGR kukukwazi ukunciphisa ukusetyenziswa kwamandla xa kuthelekiswa neendlela eziqhelekileyo zokusila. Oku kubangelwa ngokuyintloko ekukhululweni okukhethiweyo kweeminerali ezixabisekileyo, ukunciphisa ubuninzi bokugqithisa. Ukongezelela, i-inter-particle compression mechanism yenza izinto ezincinci ezincinci, ezikhokelela kwinkqubo esebenzayo yokugaya.

4. Ukuphuculwa koMgangatho weMveliso:

Itekhnoloji ye-HPGR nayo inegalelo ekuphuculeni umgangatho wemveliso. Ukukhululwa okukhethiweyo kweeminerali ezixabisekileyo kukhokelela ekunciphiseni ukuveliswa kwamasuntswana aphezulu kakhulu, anokuba ngumceli mngeni wokubuyisela kwakhona kwaye kunokukhokelela ekwandeni kokusetyenziswa kwamandla kwizigaba ezilandelayo zokusetyenzwa.

5. Ukuguquguquka kokuSebenza:

Ii-HPGR zibonelela ngokuguquguquka kokusebenza ngenxa yeeparamitha zazo ezilungelelanisiweyo zokusebenza. Umsantsa phakathi kwemiqulu unokulungelelaniswa ukulawula ukuhanjiswa kobungakanani bemveliso, ukuvumela ukulungelelanisa inkqubo kwiimpawu ezithile ze-ore kunye neemfuno zokukhulula. Ngaphaya koko, ukukwazi ukurisayikilisheka kunye nokutyumza kwakhona amasuntswana obukhulu obugqithisileyo kwenza ukuba ii-HPGR zikwazi ukusingatha uluhlu olubanzi lweesayizi zesondlo.

6. Ukusetyenziswa kwiindidi ezahlukeneyo zentsimbi:

Itekhnoloji ye-HPGR isetyenziswe ngempumelelo kwiintlobo ngeentlobo zentsimbi ekrwada, kuquka intsimbi ekrwada eqinileyo efana nobhedu, igolide, kunye nentsimbi ekrwada. Ezi zixhobo zihlala zifuna ukucolwa okucolekileyo ukuze kuphunyezwe inkululeko enqwenelekayo yeeminerali ezixabisekileyo. Ii-HPGRs zibonise ukusebenza kwazo ekufezekiseni ukuncipha kobungakanani besuntswana elifunekayo ngelixa kuncitshiswa ukusetyenziswa kwamandla.

7. Ukudityaniswa neeSekethe zokuSila ezikhoyo:

Ii-HPGR zinokudityaniswa kwiisekethe zokugaya ezikhoyo njengenqanaba lokugaya kwangaphambili okanye njengenxalenye yesekethe yokugaya i-hybrid. Ngokuphumeza iteknoloji ye-HPGR, ukusetyenziswa kwamandla kwizigaba ezilandelayo zokugaya, ezifana nokugaya ibhola, kunokunciphisa kakhulu, okukhokelela ekugcinweni kwamandla ngokubanzi.

8. Imingeni kunye noPhuhliso lwexesha elizayo:

Ngaphandle kweenzuzo ezininzi, kukho imingeni ehambelana nokuphunyezwa kobuchwepheshe be-HPGR. Ezi ziquka imfuno yophawu olululo lwe-ore, ulawulo lokunxiba, kunye nolawulo olwaneleyo lwesekethe ye-HPGR. Uphando oluqhubekayo kunye neenzame zophuhliso zijolise ekujonganeni nale mingeni kunye nokwandisa ukusebenza kobuchwepheshe be-HPGR ngakumbi.

Isiphelo:

I-High Pressure Grinding Rolls (HPGR) idlala indima ebalulekileyo ekufezekiseni ukuhanjiswa kwamandla ngendlela eyongayo kushishino lwemigodi. Ngokukwazi kwabo ukukhulula iiminerali ezixabisekileyo ngokukhetha kunye nokunciphisa ukusetyenziswa kwamandla, ii-HPGRs zibonelela ngeenzuzo ezibalulekileyo kwiindlela eziqhelekileyo zokusila. Ukudityaniswa kobuchwephesha be-HPGR kwiisekethe zokusila ezikhoyo kubonelela ngamathuba okuphucula ukusebenza kakuhle kombane kwimisebenzi yokulungisa izimbiwa. Ngenkqubela phambili eqhubekayo kunye nokwandiswa kwesicelo esithile, itekhnoloji ye-HPGR kulindeleke ukuba ixhaphake ngakumbi kukhangelo lweenkqubo ezizinzileyo nezisebenzayo.
