Piv nrog rau lwm homCov ntxhia pob zeb crusher, nws muaj qhov zoo ntawm cov qauv yooj yim, tsawg dua crushing phenomenon, txhim khu kev qha ua hauj lwm thiab kev ua haujlwm siab. Nws yog tsim rau coarse crushing ntawm limestone thiab thee. Tam sim no, muaj kev thov zoo rau cov cuab yeej no hauv Suav teb, tab sis vim qhov pib lig ntawm cov ntxhia hauv tsev, cov khoom siv crushing hauv tsev feem ntau yog los ntawm txawv teb chaws, thiab cov lus qhia tus nqi siab, uas ua rau cov nqi ntau lawm. Yog li ntawd, txoj kev loj hlob ntawm ib tug tshiab mineral sizer haum rau cov thee npaj nyob rau hauv Suav coal mines kom tau raws li cov kev xav tau ntawm domestic mines, Hloov pauv ntawm imports yog imminent thiab tseem ceeb heev.
1 Lub ntsiab lus ntxhia sizer yog ib hom crushing tshuab dav siv nyob rau hauv cov thee npaj cov nroj tsuag.
Cov pob zeb me me siv cov shear thiab extrusion kev txiav txim ntawm cov hniav crushing kom tawg cov khoom los ntawm ob lub rollers. Lub hauv paus tseem ceeb ntawm miner sizer yog 2 rollers, 1 rollers txhawb nqa ntawm cov kabmob ruaj khov, uas tau tsav los ntawm lub cev muaj zog nrog lub log siv, lwm cov menyuam txhawb nqa ntawm lwm cov kabmob ruaj khov, 2 rollers los ntawm ib khub ntawm kev ua haujlwm zoo synchronous iav kom ua tiav cov txheeb ze sib hloov, 2 rollers los ntawm cov menyuam rau cov ntaub ntawv shear, kom ua tiav lub hom phiaj ntawm crushing cov ntaub ntawv (1).
Mineral sizers yog tsim los ntawm prime mover, kis mechanism, reducer, lub ntsiab cav thiab lwm yam.
(1) Prime mover: Tus thawj txav ntawm cov pob zeb loj siv lub cev muaj zog, uas tuaj yeem xaiv raws li kev siv. Qhov no ua rau muaj kev siv ntau dua. Nws yog qhov yooj yim heev rau cov neeg siv uas nyob deb ntawm txoj kab hluav taws xob lossis feem ntau hloov chaw ua haujlwm.
(2) Cov txheej txheem kis tau tus mob: cov pob zeb hauv av tau txais kev siv lub log tsav, uas tuaj yeem ua rau tus neeg tsav tsheb ua haujlwm ruaj khov thiab muaj kev tiv thaiv ntau dhau.
(3) Cov cuab yeej txo qis: cov pob zeb hauv av tau txais cov qauv ntawm cov hniav qeeb kom khiav, txhawm rau kom tau txais qhov yuav tsum tau txo qhov sib piv, daim duab peb sab siv thiab iav siv los txo qhov ceev ob zaug, tus tsav ncej thiab lub ntsiab ncej yog siv tapered roller bearings.
(4) Lub tshuab tseem ceeb: (1) Lub cev lub cev: Lub tshuab tseem ceeb ntawm cov ntxhia pob zeb siv lub thawv- zoo li tus qauv, lub thav duab yog welded nrog steel phaj, txais kev sib cais hom, muaj li ntawm lub phaj hauv qab, 2 sab phaj thiab lub hau npog, 2 hniav chais yog ntsia rau ntawm cov kabmob ruaj khov ntawm tus ncej, cov kabmob txuas nrog lub thav duab los ntawm lub rooj zaum bearing. Ob lub rollers tau koom nrog ob lub zog ua tau zoo ntawm tib yam tsis muaj. ② Cov menyuam yaus: Cov haujlwm tseem ceeb ntawm cov pob zeb loj yog ob qhov kev sib txuas
Cov hniav crushing yog txuas nrog lub mandrel los ntawm tus yuam sij, thiab cov kauv txheej txheem ntawm cov hniav crushing ntawm mandrel yog paub los ntawm kev hloov lub ntsiab lub kaum sab xis ntawm cov hniav crushing. ③ Cov khoom siv pabcuam:
Lub tshuab tseem ceeb ntawm cov ntxhia sizers yog muab nrog cov cuab yeej pabcuam, qhov qis dua ntawm lub thawv lub cev yog nruab nrog lub crushing ore ntawm ob lub rollers, thiab ob lub rollers koom tes los tsim lub thib peb theem ntawm crushing, tswj cov particle loj. (4) Tshem tawm cov cuab yeej: qhov sib txawv ntawm cov phaj hniav thiab cov hlau tawg ua ib qho kev tshuaj ntsuam xyuas zoo. Cov ntaub ntawv tsim nyog granular muaj nyob rau hauv cov ntaub ntawv nkag mus rau hauv lub crushing chamber yog sai sai tawm ntawm qhov sib txawv, thaum cov ntaub ntawv bulk raug tom los ntawm cov rotating hniav thiab tawg los ntawm xuas nrig ntaus, shearing thiab cuam tshuam stretching. Cov qauv no txhim kho kev ua haujlwm ntawm kev ua haujlwm thiab kev ua haujlwm ntawm qhov loj.
Cov pob zeb loj loj crusher lub thawv yog sib sau los ntawm steel phaj, thiab lub hauv paus yog 180 channel steel. Lub thawv crushing thiab lub hauv paus yog welded tom qab zawm, thiab lub cev muaj zog ncaj qha rau ntawm lub hauv paus nrog bolts.
Tag nrho cov qauv ntawm tus sizer tau optimized. Lub reducer thiab lub thawv crushing yog tsim rau hauv ib qho kev sib xyaw ua ke, uas tuaj yeem tsis tsuas yog txuag chaw thiab cov nqi tsim khoom tab sis kuj zoo dua sealing thiab kis tau tus mob; Lub iav ncej yog ib feem raug, thiab lub hau sab sauv yog zoo kaw nrog ib feem ntawm qhov raug. Daim ntawv qhia tshwj xeeb yog qhia hauv daim duab 2.
4. Cov pob zeb me me cov hniav zoo li cov hniav ua haujlwm ntawm qhov chaw ntawm cov pob zeb hauv av tau txais cov hniav pyramid, cov ntug ntawm ib tus hniav yob rau hauv ib qho convex zawj, thiab sab nrauv ntawm cov menyuam rau hauv cov voj voog concentric. Txhawm rau kom tau txais cov khoom sib tsoo ze rau lub voos xwmfab, qhov saum npoo ntawm cov menyuam siv cov txheej txheem ntawm cov hniav sib npaug ntawm qhov sib npaug ntawm qhov sib npaug. Cov hniav ntawm lwm cov menyuam yog ncaj qha rau ntawm qhov chaw ntawm lub prism, thiab qhov kev ncua deb ntawm sab saum toj ntawm cov hniav ntawm ib tug menyuam thiab nto ntawm lwm cov menyuam thiab qhov sib nrug ntawm ob tug hniav yog hais txog qhov siab tshaj particle loj ntawm cov khoom, raws li qhia nyob rau hauv daim duab 3.
Cov ntxhia pob zeb crusher cov hniav zoo nkauj ntawm cov hniav ua haujlwm ntawm cov hniav ntawm cov pob zeb hauv av yog cov hniav, thiab cov hniav zoo li pom hauv daim duab 4. Txhua 4 cov hniav cov hniav yog embedded rau ntawm lub tes tsho hniav, uas yog tsau rau ntawm lub log diav rawg los ntawm screws, thiab lub log diav rawg yog square. Cov hniav ua los ntawm cov hlau yog ntsia nrog cov ntsia hlau ntawm ib feem ntawm cov hniav txiav cov khoom sib txuas, thiab cov hniav yob yog teem rau hauv cov duab kauv. Tus qub sizer siv cov menyuam cov hniav thiab lub ntsej muag rov qab rau cov menyuam kom tawg, tab sis siv cov txheej txheem ntawm cov hniav sib tsoo los ntawm tus yuam sij thiab ncej txuas rau hauv ib lub kauv, siv cov hniav thiab cov hniav kom yob cov khoom crushing.
4.3 Cov ntxhia sizers crusher yob cov hniav profile thiab kev npaj ntawm Scheme 3 ntxhia sizer yog tib yam thiab txawv ntawm Scheme 2 nyob rau hauv uas txhua tus hniav cov menyuam yog tsim los ntawm ib tug mandrel thiab ib tug crushing hniav. Lub crushing hniav yog txuas nrog lub mandrel los ntawm ib tug yuam sij, thiab lub kauv txheej txheem ntawm crushing hniav ntawm lub mandrel yog paub los ntawm kev hloov lub keyway Angle ntawm lub crushing hniav.
