Dab tsi yog daim ntawv cog lus pob zeb ua haujlwm index

Bond Ball Mill Work Index (BBWI) yog ib qho kev ntsuas ntawm qhov tsis kam ntawm cov khoom rau kev sib tsoo hauv lub pob zeb. Nws tuaj yeem siv los txiav txim siab lub zog sib tsoo uas yuav tsum tau muaj rau kev muab cov khoom siv nyob rau hauv pob zeb sib tsoo. BBWI tau txiav txim siab los ntawm kev sib tsoo cov qauv ntawm cov khoom siv hauv lub pob zeb txheem thiab ntsuas lub zog siv kom ua tiav cov khoom loj.

BBWI suav nrog cov qauv hauv qab no:

Qhov twg:

BBWI yog Bond Ball Mill Work Index (kWh/t),

P80 yog 80% dhau qhov loj ntawm cov khoom (μm), thiab

F80 yog 80% dhau qhov loj ntawm qhov pub (μm).

BBWI feem ntau yog siv rau hauv kev ua ntxhia thiab kev sim metallurgical los ntsuas qhov kev sib tsoo ntawm cov ore thiab txiav txim siab lub zog yuav tsum tau ua rau kev sib tsoo circuits. Nws feem ntau yog siv ua ke nrog lwm cov kev sib txuas, xws li Bond Rod Mill Work Index (RWI), los muab cov yam ntxwv zoo ntawm cov khoom sib tsoo.

BBWI yog qhov tshwj xeeb tshaj yog tsim nyog rau kev tsim thiab ua kom zoo sib tsoo circuits hauv cov ntxhia ua cov nroj tsuag, vim nws pab kwv yees lub zog siv thiab txo qhov loj me ntawm ntau hom ore. Tsis tas li ntawd, nws tuaj yeem siv los sib piv cov kev sib tsoo ntawm cov khoom sib txawv thiab ntsuas qhov cuam tshuam ntawm kev hloov pauv ntawm cov khoom noj loj, ore hardness, thiab lwm yam ntawm kev sib tsoo.
