Feem ntau, muaj lub crusher ntawm koj qhov chaw pov tseg tuaj yeem txuag tau ntau lub sijhawm thiab kev ua haujlwm vim koj yuav tsis tau ua ntau npaum li cov ntaub ntawv crushing koj tus kheej. Qhov no ua rau lawv yog ib qho khoom muaj nqis heev rau txhua tus neeg uas yuav tsum tau tsoo cov ntaub ntawv sai thiab ua tau zoo.
Luv keeb kwm ntawm crushers
Thawj lub tebchaws United States patent rau lub pob zeb crushing tshuab yog nyob rau hauv 1830. Nws cov thev naus laus zis tseem ceeb yog lub tswv yim poob rauj, pom nyob rau hauv lub npe nrov stamp mills, uas yuav txuas ntxiv mus rau lub hnub nyoog kub ntawm mining. Kaum xyoo tom qab, lwm US patent tau muab rau ib qho kev cuam tshuam crusher. Lub hauv paus feem cuam tshuam crusher yog tsim los ntawm ib lub thawv ntoo, cylindrical ntoo nruas, nrog hlau rauj fastened rau nws. Txawm hais tias ob qho tib si ntawm cov patents tau tso cai, tsis muaj ib tus neeg tsim khoom tau ua lag luam lawv cov khoom tsim.
Eli Whitney Blake tau tsim, patented, thiab muag thawj lub pob zeb crusher hauv xyoo 1858, nws tau hu ua Blake Puab tsaig Crusher. Blake lub crusher tau muaj zog heev uas niaj hnub no cov qauv tseem muab piv rau nws cov qauv tsim. Qhov no yog vim hais tias Blake Puab tsaig Crusher koom ua ke lub ntsiab lus tseem ceeb ntawm kev siv tshuab - lub toggle linkage - lub tswv yim cov tub ntxhais kawm ntawm kev siv tshuab tau paub txog.
Xyoo 1881, Philetus W. Gates tau txais US patent rau nws cov cuab yeej uas muaj cov tswv yim tseem ceeb ntawm niaj hnub gyratory crushers. Xyoo 1883 Mr. Blake tau sib tw Mr. Gates kom tsoo 9 cubic yards ntawm pob zeb hauv kev sib tw saib seb lub crusher twg yuav ua tiav txoj haujlwm sai dua. Lub rooj vag crusher ua tiav txoj haujlwm 40 feeb sai dua!
Lub rooj vag 'gyratory crushers tau nyiam los ntawm kev lag luam mining rau yuav luag ob xyoo caum mus txog rau thaum lub xyoo pua puv, circa 1910, thaum Blake lub puab tsaig crushers pom ib qho kev tshwm sim hauv qhov chaw. Qhov kev thov rau lub puab tsaig loj ntawm lub puab tsaig crushed skyrocketed raws li kev lag luam pib nkag siab txog lawv lub peev xwm ua thawj crushers hauv pob zeb quarries. Los ntawm Thomas A. Edison txoj kev tshawb fawb thiab kev tsim kho, cov tshuab loj heev tau tsim kho tshiab thiab muab tso rau thoob plaws Tebchaws Meskas. Cov me me lub puab tsaig crushers kuj tau tsim ua theem nrab thiab qib siab crushers.
Edison cov kev tshawb fawb nyob rau hauv kev ua liaj ua teb mining thiab crushing tshuav ib tug keeb kwm yav dhau los txhim kho pob zeb loj npaum li cas thiab cov ntaub ntawv raug txo.
Crushing yog txheej txheem ntawm kev txo lossis rhuav tshem cov khoom loj dua rau hauv cov khoom me me. Muaj plaub txoj hauv kev los tsoo.
Kev cuam tshuam: Kev sib tsoo tam sim ntawm cov khoom loj tawm tsam ib leeg nrog cov khoom tso rau nruab nrab. Ob qho khoom tuaj yeem txav mus los lossis ib qho tuaj yeem ua tau thaum lwm qhov tawm tsam nws. Muaj ob hom kev cuam tshuam kev txo qis, lub ntiajteb txawj nqus thiab dynamic.
Attrition: Rubbing cov khoom nruab nrab ntawm ob qhov chaw. Qhov no yog ib txoj hauv kev tsim nyog thaum txo cov khoom siv abrasive tsawg vim tias nws siv zog tsawg dua thaum ua haujlwm. Cov ntaub ntawv muaj zog yuav tsis ua haujlwm zoo.
Shear: Feem ntau ua ke nrog lwm txoj kev txo qis, shearing siv txoj kev txiav thiab siv thaum xav tau qhov txiaj ntsig ntxhib. Txoj kev txo qis no feem ntau pom hauv thawj crushing.
Compression: Ib qho tseem ceeb ntawm lub puab tsaig crushers, compression txo cov ntaub ntawv ntawm ob qhov chaw. Zoo heev rau cov ntaub ntawv nyuaj heev, abrasive uas tsis haum attrition crushers. Compression tsis haum rau txhua yam tacky los yog gummy.
Xaiv hom kev crushing kom raug yog qhov tshwj xeeb rau ob hom khoom uas koj tab tom tawg thiab cov khoom xav tau. Tom ntej no, koj yuav tsum txiav txim siab seb hom crusher zoo tshaj plaws rau txoj haujlwm. Khaws kev siv lub zog thiab kev ua haujlwm hauv siab yog ib txwm xav txog. Kev siv cov crusher tsis ncaj ncees lawm tuaj yeem ua rau raug nqi qeeb thiab siv zog ntau dua li qhov xav tau thaum lub sijhawm ua haujlwm.
Dab tsi yog qhov sib txawv ntawm crushers?
Muaj ntau ntau hom crushers los ntawm lub puab tsaig crushers rau impactors thiab cone crushers. Crushing yog ntau yam txheej txheem thiab hom crusher koj xav tau nyob ntawm 'theem' ntawm crushing. Peb theem tseem ceeb ntawm crushing yog thawj, theem nrab, thiab tertiary - tag nrho cov uas muaj lawv tus kheej cov txiaj ntsig tshwj xeeb. Lub hauv paus crushing yog siv cov khoom loj los ua lub zog thawj zaug los rhuav tshem cov pob zeb loj thiab tawv thiab pob zeb rau hauv me me ua ntej lawv txav mus rau theem nrab. Secondary crushing lov cov ntaub ntawv txawm ntxiv ua ntej lawv mus rau tertiary theem, uas ua rau ib tug txawm finer khoom uas yuav siv tau nyob rau hauv ntau yam kev lag luam tej yaam num.
