yog vim li cas daim ntawv cog lus pob zeb kuaj tsis siv cov khoom siab tshaj 3.36mm

Bond pob zeb kuaj, tshwj xeeb yog Bond Ball Mill Work Index (BWI) test, yog tsim los ntsuas qhov kev sib tsoo ntawm cov ntaub ntawv nyob rau hauv ib cheeb tsam chaw soj ntsuam. Yog vim li cas tsis siv cov khoom siv siab tshaj 3.36 hli (6 mesh) hauv Bond pob zeb xeem yog cov hauv paus hauv paus ntsiab lus thiab cov hom phiaj ntawm qhov kev xeem nws tus kheej. Nov yog cov laj thawj tseem ceeb:

1. Test Standardization thiab Consistency

Bond Ball Mill Work Index test yog ib qho kev ntsuam xyuas tus qauv uas muab kev ntsuas zoo ib yam thiab rov tsim dua tshiab ntawm cov khoom sib tsoo. Kev siv ib qho loj me me ntawm cov khoom ua kom ntseeg tau tias cov txiaj ntsig tau sib piv thoob plaws cov kev sim sib txawv thiab cov chaw sim. Qhov loj ntawm 3.36 hli saum toj kawg nkaus yog ib feem ntawm cov qauv no, kom ntseeg tau tias txhua qhov kev sim tau ua raws li cov xwm txheej zoo sib xws.

2. Test Specification

BWI xeem yog tsim los simulate cov txheej txheem sib tsoo hauv cov pob zeb, uas feem ntau ua haujlwm nrog cov khoom noj zoo dua. Los ntawm kev siv cov khoom uas ntxhib dhau lawm, qhov kev ntsuam xyuas yuav tsis cuam tshuam cov xwm txheej hauv kev lag luam pob zeb. Qhov loj 3.36 hli txwv kom ntseeg tau tias cov khoom yog tus sawv cev ntawm qhov yuav ua tiav hauv cov pob zeb tiag tiag.

3. Zog xam qhov tseeb

Bond Work Index yog ib qho kev ntsuas empirical uas hais txog lub zog xav tau rau kev txo qhov loj me. Kev siv cov khoom loj dua 3.36 hli yuav qhia txog qhov sib txawv ntawm lub zog uas yuav tsum tau ua kom tawg cov khoom, ua rau cov nqi qis dua thiab rov ua haujlwm dua. Qhov me me, qhov sib npaug ntawm qhov loj me ua rau muaj kev suav ntau dua ntawm kev siv hluav taws xob.

4. Keeb Kwm Keeb Kwm thiab Cov Ntaub Ntawv Empirical

Bond Ball Mill Work Index test yog tsim los ntawm Fred C. Bond nyob rau nruab nrab -20th caug xyoo. Cov txheej txheem thiab cov kev sib npaug empirical tau muab los ntawm kev sim ntau yam nrog cov khoom loj txog li 3.36 hli. Qhov xwm txheej ntawm qhov kev xeem txhais tau hais tias nws raug ntsuas rau cov ntaub ntawv nyob rau hauv qhov loj me no, thiab kev sib txawv ntawm qhov ntau yam no yuav ua rau tsis muaj tseeb ntawm qhov kev xav thiab qhov ua haujlwm Performance index.

5. Cov kev xav hauv kev sib tsoo

Hauv kev siv lub pob zeb ua haujlwm, cov ntaub ntawv feem ntau yog pre-crushed mus rau ib tug finer loj ua ntej yuav qhia rau hauv lub zeb. Qhov loj ntawm 3.36 hli sib haum nrog cov theem txo qhov loj me feem ntau pom hauv kev ua cov ntxhia, qhov twg cov ntaub ntawv raug crushed thiab hauv av ua kom zoo dua. Yog li ntawd, siv cov khoom siv saum toj no 3.36 hli yuav tsis yog cov tswv yim lossis cov neeg sawv cev ntawm cov txheej txheem sib tsoo.

Xaus

Siv cov khoom siv qis dua 3.36 hli hauv Bond pob zeb xeem kom paub meej qhov sib xws, raug, thiab qhov tseeb ntawm qhov kev xeem. Nws ua raws li lub hauv paus empirical ntawm Bond Work Index thiab qhia txog cov kev ua haujlwm raug cai ntawm cov khoom siv pob zeb, yog li muab kev ntsuas txhim khu kev qha ntawm cov khoom sib tsoo.
