Basa reHPGR muKufambisa-Kushanda Kwesimba

Nhanganyaya:

Comminution, iyo nzira yekudzikisa saizi yeore particles, inoita basa rakakosha mukuita zvicherwa kugadzirisa. Sechinyakare, hurongwa uhu hwaiitwa pachishandiswa nzira dzinoshandisa simba zvakanyanya sekugaya bhora uye SAG (Semi-Autogenous Grinding) zvigayo. Zvakadaro, nekuuya kwehunyanzvi hweHigh Pressure Grinding Rolls (HPGR), pave neshanduko huru kuenda kune mamwe magetsi-anoshanda. Chinyorwa ichi chinoongorora basa reHPGR mukufambisa-simba kwakasimba uye zvarinoita paindasitiri yezvicherwa.

1. Kushanda Kwesimba Mukuita:

Comminution mashandiro anopedza huwandu hwakakura hwesimba muzvicherwa zvekugadzira zvicherwa. Zvinofungidzirwa kuti kusvika 4% yesimba rinoshandiswa pasi rose rinokonzerwa nekushandiswa. Nokudaro, kuvandudza kushandiswa kwesimba mukugadzirisa kwave kunonyanya kukosha kune zvikonzero zvezvakatipoteredza uye zvehupfumi.

2. High Pressure Grinding Rolls (HPGR):

Tekinoroji yeHPGR inopa mhinduro inovimbisa yekufambisa-simba-rinoshanda. Michina yeHPGR ine maviri anopoterera-anotenderedza rolls, anowanzo gadzirwa nesimbi, pakati peiyo ore zvimedu zvinodyiswa. Nekushandisa yakakwira kudzvanywa kumidziyo yekudyisa, HPGRs inowana kutsemuka zvakanyanya kuburikidza ne-inter-particle compression, pane kukanganisa kana kukanganisa.

3. Mabhenefiti eHPGR muKushanda Kwesimba:

Imwe yemabhenefiti akakosha eHPGR tekinoroji kugona kwayo kudzikisa mashandisiro emagetsi zvichienzaniswa nemaitiro echinyakare ekukuya. Izvi zvinonyanya kukonzerwa nekusunungurwa kwakasarudzwa kwemaminerari anokosha, kuderedza kuwanda kwekuwedzera. Pamusoro pezvo, iyo inter-particle compression mechanism inogadzira zvinhu zvidiki zvishoma, zvichitungamira kune yakanyatso kudzika nzira yekukuya.

4. Yakavandudzwa Chigadzirwa Hunhu:

HPGR tekinoroji inobatsirawo pakuvandudza kunaka kwechigadzirwa. Kusununguka kwakasarudzika kwemaminerari akakosha kunoguma nekudzikiswa kwekugadzirwa kwema-ultra-fine particles, izvo zvinogona kunetsa kupora uye zvinogona kutungamirira kuwedzera kushandiswa kwesimba mumatanho anotevera ekugadzirisa.

5. Operational Flexibility:

HPGRs inopa shanduko yekushanda nekuda kweiyo inogadziriswa maparamita ekushanda. Mukaha uripo pakati pemapumburu unogona kugadziridzwa kudzora saizi yechigadzirwa kugovera, zvichibvumira kugadzirisa maitiro kune chaiwo ore maitiro uye kusunungurwa zvinodiwa. Uyezve, kugona kudzokorodza uye kupwanya-pwanya oversize zvimedu zvinogonesa maHPGR kubata huwandu hwakasiyana hwehukuru hwekudya.

6. Kushandiswa muMarudzi Akasiyana-siyana Esimbi:

Tekinoroji yeHPGR yakashandiswa zvinobudirira mumhando dzakasiyana dzeore, kusanganisira yakaoma rock ores semhangura, goridhe, uye iron ore. Zvishandiso izvi zvinowanzoda kugaya zvakatsetseka kuti uwane kusunungurwa kunodiwa kwemaminerari akakosha. HPGRs vakaratidza kushanda kwavo mukuwana iyo inodiwa particle size kuderedza uku vachideredza kushandiswa kwesimba.

7. Kubatanidzwa neMasekete Aripo Anokuya:

HPGRs inogona kubatanidzwa mumasekete aripo ekukuya sedanho rekutanga-kukuya kana sechikamu cheiyo hybrid grinding circuit. Nekushandisa tekinoroji yeHPGR, kushandiswa kwesimba mumatanho anotevera ekukuya, senge kugaya bhora, kunogona kudzikiswa zvakanyanya, zvichitungamira kukuchengetedza simba rose.

8. Matambudziko neKubudirira Kweramangwana:

Kunyangwe kune akawanda mabhenefiti, kune matambudziko ane chekuita nekuitwa kweHPGR tekinoroji. Izvi zvinosanganisira kudiwa kweiyo ore hunhu, roll kupfeka manejimendi, uye kudzora kwakakwana kweiyo HPGR dunhu. Kuenderera mberi kwekutsvagisa nekusimudzira kuedza kugadzirisa matambudziko aya uye nekuwedzera mashandiro eHPGR tekinoroji.

Mhedziso:

High Pressure Grinding Rolls (HPGR) inoita basa rakakosha mukuwana simba rinoshanda zvakanaka muindasitiri yezvicherwa. Nekugona kwavo kusarudza kusunungura zvicherwa zvakakosha uye kuderedza kushandiswa kwesimba, maHPGR anopa mabhenefiti akakosha pane akajairwa nzira dzekukuya. Kubatanidzwa kweHPGR tekinoroji mumasekete aripo ekukuya kunopa mikana yekuvandudza simba rose mukuita kwekuita zvicherwa. Nekuenderera mberi nekufambira mberi uye kushandiswa-chaiyo optimizations, HPGR tekinoroji inotarisirwa kuwedzera kuwanda mukutsvaga kweanoenderera uye anoshanda maitiro ekuita.
