Iyini isilinganiso sokunciphisa amaroli okugaya anengcindezi ephezulu?

Isilinganiso sokunciphisa se-High-Pressure Grinding Roll (HPGR) sibhekisela esilinganisweni sosayizi wezinhlayiyana zesiphakeli nosayizi wezinhlayiyana zomkhiqizo ngemva kokuchotshozwa. Ipharamitha ebalulekile ekuhloleni ukusebenza kahle nokusebenza kwe-HPGR.

Isilinganiso sokunciphisa singahluka kakhulu kuye ngezinto ezimbalwa, okuhlanganisa:

Usayizi Wokuphakelayo: Usayizi wento efakwe ku-HPGR.

Ukuqina kanye Nohlobo Lwezinto: Izinto ezihlukene zihlukana ngokwehlukana ngaphansi kwengcindezi.

Ingcindezi Yokusebenza: Ingcindezi ephezulu ngokuvamile iholela kumkhiqizo ocolekile kanye nesilinganiso sokunciphisa esiphezulu.

I-Roll Surface Design: Ukuthungwa kanye nephethini yezindawo eziqengqelekayo zingathinta inqubo yokunciphisa usayizi.

Okuqukethwe Umswakama: Okuqukethwe komswakamo wezinto ezibonakalayo kungaba nomthelela ekusebenzeni kahle kokunciphisa usayizi.

Ibanga Lesilinganiso Sokuncishiswa Esijwayelekile:

I-Standard Reduction Ratio: Ama-HPGR ngokuvamile azuza izilinganiso zokunciphisa ebangeni lika-1.5:1 ukuya ku-3:1. Lokhu kusho ukuthi usayizi wezinhlayiyana okukhiphayo ngokuvamile uphakathi kokuthathu kanye nezingxenye ezimbili kwezintathu zosayizi wokufakwayo.

Izilinganiso Zokuncishiswa Eziphakeme: Kwezinye izimo, ikakhulukazi lapho kucutshungulwa izinto ezithambile noma ezintekenteke kakhudlwana, noma uma i-HPGR isetshenziswa njenge-crusher yezinga eliphezulu noma le-quaternary, isilinganiso sokunciphisa singadlula u-3:1, okungenzeka sifinyelele ku-4:1 kuya ku-5:1 noma ngaphezulu.

Izinto Ezithinta Isilinganiso Sokuncishiswa:

Usayizi Wokuphakelayo Nezici Zento:

Usayizi Wokuphakelayo: Osayizi abakhulu besiphakeli ngokuvamile baholela ekuncishisweni kwezilinganiso eziphansi.

Ukuqina Kwezinto Ezibalulekile Nokuqina: Izinto eziqinile neziqhuma kakhulu ngokuvamile zidinga amandla engeziwe ukuze kuncishiswe usayizi, ngokuvamile okuholela ekuncishisweni kwezilinganiso eziphansi.

I-Material Friability: Izinto ezitholakala kalula (lezo eziphuka kalula) zingafinyelela izilinganiso ezincishisiwe eziphezulu.

Amapharamitha okusebenza:

Kusetshenziswe Ingcindezi: Izingcindezi eziphakeme ngokuvamile zikhuphula isilinganiso sokunciphisa ngokuhlephula izinto ngokuphumelelayo.

I-Roll Surface Texture: Idizayini nokuthungwa kwezindawo zeroll (isb., bushelelezi, ezigxilile, noma ezinephrofayili) zithonya ukusebenza kahle kokugaya kanye nomphumela wokusabalalisa usayizi wezinhlayiyana.

Okuqukethwe Umswakama: Umswakama ophezulu unganciphisa ukusebenza kahle kokunciphisa usayizi futhi wehlise isilinganiso sokunciphisa.

Idizayini yesiyingi nokuhlanganisa:

Isigaba Sokusetshenziswa: Ukuthi i-HPGR isetshenziswa esigabeni sokuqala, sesibili, sesithathu, noma se-quaternary sokuchotshozwa kuthinta isilinganiso sokunciphisa. Ngokuvamile ifinyelela izilinganiso zokwehliswa eziphezulu ezinyathelweni zakamuva.

Ukucutshungulwa Komfula: Usayizi womkhiqizo ohlosiwe nezimfuneko zezinqubo ezansi nomfula (njengokuntanta noma ukuleaching) zingathonya izilungiselelo zokusebenza ze-HPGR kanye nesilinganiso sokunciphisa okuhlosiwe.

Empeleni, isilinganiso esilungile sokunciphisa se-HPGR sinqunywa ngokulinganisa usayizi womkhiqizo ofunekayo, ukonga kwamandla, nezici ezithile zezinto eziphakelayo.
