Qhov teeb meem tsis muaj leej twg hais txog ntawm Lub Sijhawm Nyiaj Txiag
Ib tus thawj tswj hwm ntawm thaj chaw nyob rau sab hnub tuaj Asia ib zaug tau hais rau kuv tias nws lub khob hliav qab crusher tau siv liner peb zaug sai dua li cov chaw tsim khoom kwv yees kev pab cuam lub neej. Nws tsis tau hloov lub tshuab, tsis tau hloov tus neeg teb xov tooj, thiab tsis tau hloov CSS (Closed Side Setting -) qhov sib txawv ntawm cov crushing nto uas tswj cov khoom loj). Dab tsi tau hloov pauv yog cov khoom noj khoom haus: nws txoj haujlwm tau hloov pauv los ntawm cov pob zeb blasted limestone rau dej pebble los ntawm qhov chaw nyob ze.
Zaj dab neeg ntawd muaj ntau dua li cov neeg siv khoom siv feem ntau paub. Kev lag luam nyiam kho cov khoom hnav raws li cov khoom lag luam - xaj tib qib, tib qhov profile, tib qhov ntau npaum li xyoo tas los. Tab sis thaum koj cov khoom noj hloov pauv, txawm tias ib nrab, koj tab tom khiav ib puag ncig sib txawv hauv tib lub steel ncej. Cov manganese uas kav yim lub hlis ntawm cov pob zeb zeb zeb yuav ploj mus rau hauv peb ntawm dej gravel. Lub tshuab tshuab uas ua tau zoo ntawm cov tshiab blasted granite tuaj yeem tawg ntawm siab -silica cobble. Ua qhov tsis ncaj ncees lawm tsis yog ua mob rau koj cov nyiaj siv nyiaj txiag nkaus xwb - nws cuam tshuam koj lub sijhawm tsim khoom, koj qhov kev sib tw gradation, thiab thaum kawg koj ua raws li daim ntawv cog lus.
Cov lus qhia no rhuav tshem raws nraim li cas thiab yog vim li cas pub hom hloov koj lub tswv yim hnav, thiab kev txiav txim siab dab tsi koj yuav tsum tau ua nyob rau hauv txhua theem ntawm crushing circuit.
River pob zeb crushing khoom
Ntu 1: Ob yam khoom tsis zoo ib yam li lawv saib
Ua ntej sib tham txog kev xaiv qhov chaw, nws yuav pab kom nkag siab qhov koj tab tom crushing tiag tiag.
Blasted chaw txua txiag zebtuaj txog ntawm lub crusher li angular, cov khoom tawg tshiab tshiab. Lub ntsej muag tawg yog ntxhib, uas muab lub puab tsaig daim hlau thiab lub khob hliav qab ib yam dab tsi los tuav. Cov mineralogy sib txawv los ntawm kev tso nyiaj - limestone yog mos thiab qis- puas, granite thiab basalt nqa siab silica thiab siab Bond Work Index qhov tseem ceeb - tab sis cov geometry ua haujlwm rau koj qhov kev nyiam. Angular hais interlock nyob rau hauv lub crushing chamber, siab tsim tau zoo, thiab lub pob zeb tawg raws li ntuj puas kab.
River gravel thiab pebblesyog ib qho teeb meem sib txawv. Ntau pua xyoo ntawm kev yaig hydraulic tau sib npaug txhua qhov chaw. Cov ntsiab lus silica nyob rau hauv cov dej ib txwm muaj-cov nyiaj tau los ntau tshaj li 70%, muab lawv tso rau ntawm cov khoom abrasive tshaj plaws uas koj tuaj yeem khiav ntawm lub crusher. Tus du, sib npaug morphology txhais tau hais tias cov khoom zoo li plam hauv cov crushing chamber es tsis yog tawg kom huv. Qhov slippage no ua rau kom lub zog khib nyiab ib tuj, ua kom tsis sib luag ntawm qhov chaw sib chwv, thiab ua rau cov khoom siv thauj khoom nyob rau hauv kaw -circuit systems - lub ntsiab lus ntau cov khoom dhau los ntawm crusher ntau zaus ua ntej mus txog qhov tshwj xeeb.
Nyob rau hauv cov ntsiab lus: tib lub khob hliav qab crusher khiav tib CSS ntawm dej pebble piv rau limestone chaw txua txiag zeb tuaj yeem qhia qhov sib txawv ntawm liner noj ntawm 3 mus rau 5 zaug. Qhov kev sib txawv ntawd tsis yog kev tsim khoom tsis raug. Nws yog physics.
Ntu 2: Yuav Ua Li Cas Cov Khaub Ncaws Hnav Hloov - thiab Vim Li Cas Nws Tseem Ceeb rau Kev Xaiv Khoom
Qhov tseem ceeb hnav mechanism nyob rau hauv quarry pob zeb daim ntaub ntawv yog ib tug ua ke ntawmcuam tshuamthiabpuas. Fresh blasted pob zeb hits lub liner nyuaj rau nkag, ces tau nyem. Manganese steel vam meej nyob rau hauv ib puag ncig no vim tias nws ua haujlwm - hardens nyob rau hauv kev cuam tshuam - txheej txheej saum npoo yuav nyuaj dua vim nws nqus cov kev ntxhov siab, tsim lub plhaub tiv thaiv saum HB 500 uas tiv thaiv kev puas tsuaj ntxiv.
River gravel qhia txog kev hnav khaub ncaws thib peb:peb- lub cev puas, tsav los ntawm dawb- txav silica particles ua raws li micro- txiav cov neeg sawv cev ntawm cov khoom thiab cov kab hauv kab. Cov txheej txheem no tshwj xeeb yog kev puas tsuaj thaum ntxov nyob rau hauv lub neej liner, ua ntej ua haujlwm - txheej tawv tawv tau ruaj khov. Thawj tus nqi hnav ntawm cov ntaub ntawv tshiab hauv daim ntawv thov dej gravel feem ntau yog alarmingly siab - ces nws qeeb raws li qhov saum npoo hardens - tab sis los ntawm qhov ntawd, geometry twb hloov lawm thiab koj cov khoom nkhaus tau drifted.
Qhov no yog vim li cas tus qauv Mn13 (13% manganese) ua haujlwm tsis zoo hauv dej gravel: nws tsis muaj cov ntsiab lus manganese txaus kom ua tiav qhov tseem ceeb ntawm qhov tawv tawv hauv qab muaj kev cuam tshuam lub zog.Mn18 yog qhov tseeb hauv paus rau dej pebble theem nrab thiab qib thib ob crushing.Rau kev tso nyiaj nrog cov ntsiab lus silica uas tau lees paub siab dua 60%, lossis rau kev ua haujlwm ua haujlwm tsis tu ncua siab -tonnage ntau lawm, Mn22 muab kev sib sib zog nqus thiab nrawm nrawm dua hauv qab hnyav. Qhov kev hloov kho tshiab tsim nyog ntsuas thaum siv liner ntawm Mn18 tseem khiav nrawm rau koj lub qhov rais txij nkawm.
Rau qhov xav tau tshaj plaws silica-tsav hnav ib puag ncig - qhov twg txawm tias Mn22 hloov pauv sai dua li kev lag luam lees paub - lo lus teb yog tsis muaj manganese ntau dua. Nws yog ib hom khoom sib txawv kiag li:Titanium carbide (TiC) ntxig lub tais liner thiab Concave rau lub khob hliav qab crusher coj qhov chaw. Cov khoom no tau kos ultra- tawv TiC ceramic rods (hardness saum HV 3000, kwv yees li ob npaug ntawm cov qauv carbide) ncaj qha rau hauv manganese steel matrix ntawm qhov siab tshaj -cov cheeb tsam hnav. Qhov tshwm sim yog kev tiv thaiv hauv cheeb tsam uas outlasts pa manganese los ntawm 3 mus rau 5 zaug, txo qhov hloov zaus ntau dua 60%. Hauv daim ntawv teev npe granite crushing daim ntawv thov, ib txheej ntawm TiC-insert liners khiav 2,200 teev piv rau 700 teev rau tus qauv Mn18 - 34% txo tus nqi ib tuj crushed. Rau dej gravel nrog piv silica loading, kev lag luam zoo sib xws.

Ntu 3: The Primary Stage - Qhov twg River Gravel Fights Back First
Cov neeg ua haujlwm feem ntau tsom rau lawv cov khoom siv- kev xaiv xim ntawm lub khob hliav qab, vim tias theem nrab thiab theem nrab yog qhov uas silica-tsav abrasion tshwm sim loj tshaj plaws. Tab sis thawj lub puab tsaig crusher yog qhov twg dej gravel's rounded morphology tsim nws thawj qhov teeb meem:swb.
Txheem lub puab tsaig phaj hniav profiles yog tsim rau angular blasted pob zeb. Cov hniav tuav lub ntsej muag tawg thiab siv zog compressive zoo. Ntawm cov pob zeb sib npaug dej, tib qhov profile tso cai rau cov khoom siv caij thiab tawm ntawm thaj tsam crushing es tsis yog tawg. Qhov no txo qhov kev sib tw, nce kev hnav ntawm qhov kawg ntawm lub puab tsaig phaj (tus yam ntxwv tsis sib xws ntawm kev ua haujlwm hauv dej gravel), thiab yuam tus neeg teb xov tooj kom txais cov khoom coarser dua li qhov teeb tsa xav tau.
Cov tshuaj yog ib tug hniav profile tshwj xeeb engineered los tuav rounded nto - nce cov hniav, hloov lub kaum sab xis geometry, thiab nyob rau hauv heev silica mob, kev siv ntawmTitanium Carbide (TiC) Ntxig Kho Thiab Viav Vias Lub Cev Puab Rau Lub Puab Crusher. Zoo li lawv lub khob hliav qab, TiC-ntxig lub puab tsaig daim hlau embed cov khoom siv tawv tawv rau hauv qhov chaw ntawm kev hnav siab tshaj plaws, txuas ntxiv kev pabcuam lub neej zoo heev hauv cov ntawv thov uas cov qauv manganese yuav hloov txhua ob peb lub lis piam. Rau qhov siab - ntim dej gravel thawj zaug crushing kev lag luam, qhov no tuaj yeem txhais tau tias qhov sib txawv ntawm qhov kev hloov pauv txhua hli thiab kev hloov peb lub hlis twg - txo qhov tseem ceeb ntawm lub sijhawm crane, nqi zog, thiab kev cuam tshuam ntau lawm.
Ntu 4: Kev Xaiv Cov Khoom Siv - Dab Tsi Dej Gravel Forbids
Ib qho kev ua yuam kev kim tshaj plaws hauv dej gravel ua haujlwm yog ua haujlwm cuam tshuam rau cov khoom siv siab -silica vim tias tus nqi peev qis dua lossis vim nws ua haujlwm ntawm daim ntawv cog lus qub limestone.
Impact crushers - kab rov tav ncej impactors thiab VSIs siv nyob rau hauv thawj los yog theem nrab lub luag hauj lwm - ua hauj lwm los ntawm siab - tshaj tawm kev cuam tshuam. Tshuab tuav tig ntawm qhov ceev ntawm 30 mus rau 50 m / s thiab cov khoom tawg los ntawm kev hloov hluav taws xob kinetic. Ntawm limestone, qhov no yog qhov ua tau zoo thiab kev lag luam. Nyob rau hauv dej gravel nrog 60 mus rau 70% silica cov ntsiab lus, txheem tshuab tuav tau noj nyob rau hauv 200 mus rau 500 teev ua hauj lwm. High- chrome tshuab tuav, uas muaj kev tiv thaiv zoo heev, yog nkig: ib qho kev npaj txhij txog loj ntawm quartzite los yog tramp cobble tuaj yeem ua rau puas tsuaj puas tsuaj ntau dua li kev tswj xyuas. Tus nqi kho rau lub rotor puas yog ntau zaus tus nqi ntawm kev xaiv hom crusher hauv thawj qhov chaw.
Rau dej gravel,compression crushers yog qhov yuav tsum tau ua rau theem pib thiab theem nrab. Lub puab tsaig crushers tuav qhov kev txo qis nrog kev ruaj khov rau cov khoom noj sib txawv. Lub khob hliav qab crushers coj mus rau theem nrab thiab theem nrab txo, siv inter-particle crushing uas ib feem tiv thaiv lub liner nto los ntawm kev cia pob zeb- ntawm - pob zeb sib cuag. VSI units tuaj yeem raug ntxiv raws li qhov kev xaiv shaping theem los daws qhov teeb meem cubicity - dej gravel's rounded natural shape tsis tsim cov angular, interlocking aggregate uas txoj kev hauv paus thiab pob zeb siv yuav tsum tau - tab sis VSI lub luag hauj lwm yuav tsum tau shaping, tsis yog thawj loj txo.
