Nyob rau hauv kev pom ntawm lub superparticle loj ntawm cov paug tawm los ntawm pulverized thee crusher nyob rau hauv lub thee npaj cog, nws tsis tau mus txog <50mm tsim raws li txoj cai, qhov tseeb sim thaiv kev ntxuav thee system> Qhov feem ntawm 50m yog 17% -20%, uas ncaj qha cuam tshuam rau calorific nqi ntawm kev lag luam thee, thiab ces cuam tshuam cov nyiaj tau los ntawm kev muag khoom. Los ntawm kev txheeb xyuas cov teeb meem ntawmmineral sizers, combining lub hauv paus ntsiab lus crushing thiab influencing yam, cov kev hloov pauv ntawm crusher phaj yog muab tso rau pem hauv ntej. Daim ntawv thov tswv yim qhia tau hais tias cov teeb meem ntxhib khiav ntawm pulverized thee crusher tau raug daws tau zoo tom qab kev hloov kho ntawm cov phaj hniav.
Coal preparation plant is a coal mine type power coal preparation plant, the separation process is composed of heavy medium shallow tank system of lump coal, heavy medium cyclone system of final coal, rough slime decanting system and slime press filter system. The bulk coal heavy medium shallow tank system is graded by the raw coal grading screen to get the material on the screen, the raw coal grading screen after desliming into the shallow tank for sorting, to get two kinds of coal and gangue products, after the clean coal is deslimed by the desliming screen, < 30mm pellets are further dehydrated by centrifuge, > The 30mm grain grade goes into the crusher for crushing, and the broken products are mixed with the dehydrated products of the centrifuge and then transferred together into the product warehouse for sale. In the actual production process, it is found that there is a super-particle size of the coal crusher's discharge, and the block coal cleaning system is >. Qhov kev faib ua feem ntawm 50 hli yog 17% mus rau 20%, uas cuam tshuam ncaj qha rau tus nqi calorific ntawm kev lag luam thee thiab nws qhov muag.
Raws li cov ntxhia sizers crushing lub hauv paus ntsiab lus, thaum qhov chaw nyob deb ntawm ob cov hniav yob yog tsau thiab lub rotating ceev yog tsau, qhov paug particle loj yog txiav txim los ntawm ob peb yam, xws li qhov siab ntawm cov hniav, txoj kab uas hla ntawm lub hauv qab ntawm cov hniav rolls, thiab cov kev npaj ntawm axial thiab radial sib nrug ntawm cov hniav. Tam sim no, lub crusher siv nyob rau hauv cov thee npaj cog, qhov zoo ntawm cov hniav yog siab dhau lawm, txoj kab uas hla ntawm hauv qab ntawm cov hniav yob yog me me, lub axial nrug ntawm cov hniav yog loj heev, cov hniav phaj yog ob - kab staggered 7- cov hniav phaj, thiab cov radial kev npaj yog ib tug ib tug linear kev npaj, yog li ntawd thaum lub sij hawm me me ntawm cov hniav yog ib yam nkaus thiab siv tau. qhov chaw ntim loj heev, qhov tseeb cov khoom tawg particle loj yuav dhau qhov yuav tsum tau particle loj, thiab coarse phenomenon yuav tshwm sim.
1.2 Kev daws kom tau raws li kev lag luam xav tau:
Ib qho kev hloov pauv ua ntej tau tsim, thiab qhov teeb meem ntawm kev khiav ntxhib tau daws los ntawm kev sib tsoo me me ntawm cov hlau thaiv hauv cov hniav thiab nruab nrab ntawm cov hniav, thiab 323 * pulverized thee crusher raug coj los ua cov khoom kuaj. Txij lub Tsib Hlis 9 txog Lub Tsib Hlis 19, 2016, thee npaj cog tau hloov kho 12 tus hniav daim hlau ntawm qhov chaw blanking ntawm 323 huv thee crusher thiab dhau qhov kev hloov kho kev sim . 50mm granular cov ntaub ntawv tau zoo lawm, los ntawm kev soj ntsuam sim, > Qhov feem ntawm 50mm granular khoom yog 5% {18% ntawm 18%. theem pib ntawm kev hloov pauv. Cov txheej txheem kev sim tau ua tiav cov txiaj ntsig xav tau, yog li nws tau txiav txim siab ntxiv tias txoj kev nce lub thickness ntawm crusher hniav phaj thiab cov hniav hau thiab qhov siab ntawm cov hniav tuaj yeem daws qhov teeb meem ntawm qhov paug tawm ntawm crusher. Yog li ntawd, nws yog thaum kawg txiav txim siab mus nqa tawm technical transformation ntawm lub crusher hniav phaj. Hauv qab ntawm thawj crusher hniav phaj yog nce los ntawm 15 hli, txoj kab uas hla ntawm cov hniav yob yog nce, lub thickness ntawm crushing hniav yog widened los ntawm 10 hli, lub axial spacing ntawm crushing hniav yog luv, thiab ib tug crushing me me hniav yog ntxiv nyob rau hauv tus Tsov tus tw txoj hauj lwm ntawm cov hniav, thiab thawj ob - kab interlace } mus rau 7 {{23} 7- zuv phaj. Nyob rau tib lub sijhawm, hnav-resistant steel muaj pes tsawg leeg ntawm crushing iav phaj yog hloov kho kom hnav tsis kam thiab kev pab cuam lub neej ntawm cov iav phaj.
2. Kev siv cov txheej txheem ntawm cov hniav hloov pauv
2.1 Technical transformation tswvyim ntawm hniav phaj
Cov thee npaj cog tam sim no siv cov ntxhia pob zeb, thiab cov hniav txhuam hniav yog ob kab ntawm staggered 7-hnub hniav phaj. Cov hniav phaj ntawm cov hniav ntxuav hniav crusher ua ntej qhov kev hloov pauv yog qhia hauv daim duab 1. Cov hniav qhov siab yog 60 hli, thiab qhov kev ncua deb ntawm cov hniav tawg yog 70 hli los ntawm sab saum toj ntawm cov hniav pem hauv ntej mus rau hauv qab ntawm cov hniav phaj yog 135 hli. Tam sim no, los ntawm kev nce hauv qab ntawm thawj MMD cov hniav phaj los ntawm 15mm thiab nce txoj kab uas hla ntawm hauv qab ntawm cov hniav yob, sab saum toj ntawm cov hniav pem hauv ntej yog 150mm mus rau hauv qab ntawm cov hniav phaj: lub thickness ntawm cov hniav qub yog nce los ntawm 25mm mus rau 35mm, thiab txhua hnub nyob deb ntawm cov hniav tawg axes yog luv rau 60m. Cov hniav txiav qhov siab yog 60 hli, thiab cov hniav hloov kho crusher phaj yog ob npaug 7-hnub hniav phaj. Tom qab kev hloov pauv ntawm cov hniav phaj ntawm thaiv kev ntxuav cov thee crusher, cov txiaj ntsig kev ntsuam xyuas pom tau tias qhov tso tawm ntawm 323 thiab 324 crushers nyob rau hauv nruab nrab . 50mm granular khoom piv < 0.8%, < Qhov feem ntawm 30 hli pulverized thee cov ntaub ntawv tau nce mus rau ntau dua 65% : thiab los ntawm kev saib xyuas cov kev khiav hauj lwm 3 ntawm 2 cov khoom siv tam sim no, crusher yog 60 ~ 65A, Lub gearbox kub yog 28 ~ 31 degree, kev co yog 1.8 ~ 3.0mm, thiab cov cuab yeej ua haujlwm tsis zoo yog qhov qub. Cov kev hloov kho kev sim ntawm cov hniav phaj ntawm crusher hauv thee npaj cog tau ua tiav cov txiaj ntsig zoo.
