Uyini usayizi wokuphakelayo we-HPGR?

I-HPGR imele imiqulu yokugaya enengcindezi ephezulu. Ubuchwephesha bokukhiqiza obusebenzisa isigayo serola esinomfutho ophezulu ukunciphisa usayizi wezinhlayiya ze-ore, ngokuvamile ebangeni lamamilimitha ambalwa ukuya kumakronsi ambalwa. I-HPGR ivame ukusetshenziswa njengendlela eyonga kakhulu futhi engabizi kakhulu kubuchwepheshe bokugaya bendabuko, obufana nezigayo zamabhola kanye nezigayo ze-SAG.

I-HPGR iqukethe amaroli amabili aphikisayo asebenzisa ukucindezela okuphezulu ezinhlayiyeni zensimbi njengoba zidlula phakathi kwamaroli. Ingcindezi esetshenzisiwe ingasukela ku-50 kuye ku-400 MPa, kuye ngohlelo oluthile. Ukucindezela okuphezulu kubangela ukuthi izinhlayiya ze-ore ziphuke noma ziqhekeke, zinciphise ubukhulu bazo futhi zenze umkhiqizo omfaniswano omningi onenhlawulo embalwa.

Usayizi wokuphakelayo we-HPGR (Ama-High Pressure Grinding Rolls) uyahlukahluka kuye ngohlelo lokusebenza nomshini othile osetshenzisiwe. Ngokuvamile, i-HPGR yakhelwe ukuphatha osayizi abakhulu bokuphakelayo uma kuqhathaniswa nobunye ubuchwepheshe bokugaya, obufana nezigayo zamabhola noma izigayo ze-SAG.

Ngokuvamile, ububanzi bosayizi wokuphakelayo we-HPGR bungahluka ukusuka kumamilimitha ambalwa ukuya kumasentimitha ambalwa, kuye ngohlelo oluthile. Kodwa-ke, kubalulekile ukuqaphela ukuthi ubukhulu bobukhulu bokudla bunqunyelwe ububanzi be-roll kanye negebe phakathi kwama-roll. Ukwengeza, ubulukhuni kanye nokuhwamuka kokuphakelayo kungase kuthinte usayizi wokuphakelayo ongacutshungulwa ngempumelelo yi-HPGR.

Sekukonke, usayizi wokuphakelayo we-HPGR uvame ukuba mkhulu kunobunye ubuchwepheshe bokugaya, okuvumela ukuqhutshwa ngempumelelo kwezinhlayiya ezinkulu futhi okungenzeka kunciphise isidingo samasekhethi okugaya angezansi komfula.
