Siab Chrome Hlau
High chrome hlau muaj qhov zoo tshaj plaws kev puas tsuaj ntawm txhua yam khoom siv tshuab tshuab. Chrome content typically falls between 15% and 28%, creating a dense microstructure of chromium carbides that is extraordinarily hard, commonly in the range of HRC 60 to 64. In clean, abrasive secondary and tertiary applications, such as limestone crushing for aggregate, clean gravel processing, or manufactured sand production, high chrome bars outlast manganese or martensitic options by a significant paj ntaub.
Qhov kev txwv yog brittleness. High chrome hlau muaj kev kam rau siab heev rau kev cuam tshuam los ntawm tramp hlau. Ib daim ntawm rebar los yog ib tug loader hniav nkag mus rau hauv lub crusher chamber tuaj yeem tawg lub chrome bar ncaj nraim. Vim li no, cov hlau chrome siab tsuas yog tsim nyog thaum cov hlau ntws tawm thiab tshem tawm tau lees paub thiab cov khoom noj zoo ib yam.
Ceramic Composite thiab TiC Insert Bars
Ceramic thiab titanium carbide composite tuav sawv cev rau cov kauj ruam tom ntej hauv kev coj ua. Ceramic inserts, feem ntau alumina hais nrog hardness ib ncig ntawm 1600 HV, yog embedded rau hauv martensitic los yog chrome hlau matrix thaum lub sij hawm casting txheej txheem. Qhov tshwm sim yog ib qho bar uas ua ke nrog lub hauv paus alloy qhov cuam tshuam rau kev ua siab ntev nrog kev txhim kho nto hardness ntawm cov ntsiab lus uas puas yog khaus tshaj plaws.
Cov kab sib xyaw ua ke no zoo haum rau kev sib tw thib ob thiab qib thib ob ntawm cov khoom siv abrasive heev uas pub noj huv tuaj yeem tswj tau. Hauv cov xwm txheej zoo, lawv txuas ntxiv lub neej kev pab cuam los ntawm ib qho ntawm ob mus rau plaub piv rau cov qauv tuav. Txawm li cas los xij, cov khoom siv ceramic lossis TiC yog qhov nkag siab rau taw tes - thauj khoom cuam tshuam los ntawm cov khoom siv tsis tau. Siv lawv nyob rau hauv ib daim ntawv thov nrog tramp hlau txaus ntshai yog ib txoj kev txhim khu kev qha kom luv lawv lub neej es tsis ntev nws.
DUMA Blow Bars Rau Impact Crushers
Yuav Ua Li Cas Xaiv Txoj Cai Blow Bar
Xaiv lub tshuab tshuab los ntawm peb qhov sib txawv ntawm qhov ntsuas ua ke: qhov abrasiveness ntawm koj cov khoom noj, qhov kev pheej hmoo ntawm kev cuam tshuam los ntawm cov khoom loj lossis cov khoom tsis sib tsoo, thiab theem ntawm crushing koj ua.
Kauj Ruam 1: Ntsuam xyuas koj cov khoom noj
Silica- cov pob zeb nplua nuj xws li basalt, granite, thiab quartzite yog abrasive heev thiab hnav los ntawm cov alloys softer sai. Limestone thiab pob zeb yog nruab nrab abrasive. Cov av mos thiab cov xuab zeb- hnyav hnyav yog tsawg hauv silica hardness tab sis tuaj yeem muaj cov ntsiab lus nplua nuj, uas sandblasts qhov hnav ntawm qhov sib txawv. Qhov siab dua qhov abrasiveness ntawm koj cov khoom, qhov nyuaj koj lub tshuab tshuab yuav tsum yog.
Kauj Ruam 2: Ntsuam xyuas koj cov tramp hlau thiab kev pheej hmoo kis kab mob
Yog tias koj tab tom crushing demolition pov tseg, sib tov rubble, los yog reclaimed asphalt uas yuav muaj rebar, cable, los yog lwm yam hlau, koj qhov kev txhawj xeeb tseem ceeb yog tiv thaiv bar puas. Manganese hlau thiab txheem martensitic alloys nqus cov kev cuam tshuam. High chrome hlau thiab ceramics tsis.
Kauj Ruam 3: Ua kom haum rau koj theem crushing
Lub hauv paus crushing tuav cov khoom noj loj tshaj plaws thiab cov khoom siv tsis tau tshaj plaws. Manganese lossis martensitic tuav yog cov qauv xaiv. Cov ntawv thov thib ob thiab qib siab feem ntau ua cov txheej txheem me me, huv si, thiab ntau dua cov khoom noj, uas yog qhov nyuaj ntawm cov alloys nrog rau siab chrome thiab ceramic composites ua tau zoo tshaj plaws.
Ib txoj hauv kev nrawm rau kev txiav txim siab: yog tias kev tawg yog koj qhov kev pheej hmoo loj tshaj plaws, mus rau manganese. Yog tias qhov hnav tsis taus ntxov ntxov yog koj tus nqi loj tshaj plaws, mus rau chrome lossis ceramic, muab koj cov khoom noj kom huv txaus los txhawb nws.
Yam Tseem Ceeb Uas Muaj Kev Nyuaj Siab Tshaj Plaws Hnav Lub Neej
Txawm tias tom qab xaiv cov khoom tsim nyog, ntau yam haujlwm ua haujlwm txiav txim siab ntev npaum li cas koj cov tuav yuav kav ntev.
Pub loj ncaj qha cuam tshuam rau hnav. Cov khoom noj loj dua ua rau muaj kev ntxhov siab ntau dua rau ntawm qhov bar ntawm txhua qhov cuam tshuam, uas nyiam cov hlau hnyav dua. Kev nplua ntau dhau ntawm cov khoom noj, tshwj xeeb tshaj yog thaum crushing xuab zeb los yog av- cov khoom hnyav, ua zoo li cov xuab zeb nruam nruam thiab ua kom lub ntsej muag hnav ntawm txhua yam hlau.
Rotor ceev hloov lub zog ntawm txhua lub tshuab tshuab cuam tshuam. Cov rotor siab dua ua kom lub zog kinetic thiab dhau los, tab sis lawv kuj tsim kom muaj cua sov ntau dua thiab ua kom nrawm dua. Moisture hauv pub ntxiv rau hnav thiab. Dej yog qee zaum siv rau kev tiv thaiv plua plav ntawm qhov chaw, uas yog qhov tsim nyog, tab sis kev qhia nws mus rau hauv cov dej crusher yuav tsum tau txo qis thaum ua tau.
Kev tswj kev nplua nyiaj feem ntau tsis saib xyuas. Ib qho ua ntej - tshuaj ntsuam grizzly uas tshem tawm cov khoom zoo ua ntej nws nkag mus rau hauv lub crusher txo qhov hnav, tshwj xeeb tshaj yog nyob rau hauv cov xuab zeb thiab gravel los yog av- daim ntaub ntawv hnyav. Yog tias koj cov grizzly tuav tau txhaws los yog teeb tsa dav dav, koj tab tom tso cov khoom tsis tsim nyog rau koj lub tshuab tshuab.
Geometry thiab Configuration
Tshaj li kev xaiv cov khoom siv, tshuab geometry cuam tshuam rau crushing efficiency thiab cov khoom zoo. Cov kab ncaj nraim xa cov kev sib cuag tsis sib xws thoob plaws qhov ntev ntawm qhov bar thiab yog qhov kev teeb tsa feem ntau. Wing-ntiv taw tuav cuam tshuam lub zog ntawm cov npoo sab nrauv, uas tuaj yeem txhim kho cov khoom siv hauv thawj daim ntawv thov nrog cov khoom noj loj. Segmented lossis modular designs tso cai rau cov ntu hnav kom hloov pauv yam tsis hloov tag nrho cov bar, uas tuaj yeem txo cov nqi hauv daim ntawv thov.
Rotor configuration kuj tseem ceeb. Ib tug plaub-bar rotor khiav tag nrho cov kab siab ua haujlwm tau zoo hauv cov ntawv thov qib siab nrog cov khoom me me, zoo ib yam. Nyob rau hauv feem ntau, ib tug sib tov ntawm ob siab thiab ob tug luv bar muab kev tiv thaiv zoo dua rau lub rotor lub cev thaum tuav crushing efficiency.
Thaum twg los hloov lossis hloov koj cov Bars
Tshuab tshuab hnav tsis sib xws ntawm lawv lub ntsej muag. Flipping lub bar thaum hnav ntawm ib sab mus txog 50% txuas ntxiv tag nrho lub neej bar los ntawm kev faib cov hnav kom sib npaug. Hloov cov tuav ua ntej lawv siv tag tiv thaiv lub cev rotor los ntawm kev sib cuag ncaj qha nrog cov khoom noj. Thaum lub bar profile dhau los ua qhov tsis sib xws, cov khoom zoo li raug mob thiab rotor tshuav nyiaj li cas raug cuam tshuam.
Kev saib xyuas cov khoom tso tawm crushing yog ib txoj hauv kev los txiav txim rau qhov bar. Yog tias cov khoom gradation pib hloov mus rau qhov loj me me ntawm tib lub tshuab teeb tsa, nws feem ntau qhia tias bar hnav tau hloov qhov cuam tshuam zoo geometry. Ib qho kev poob hauv kev xa tawm ntawm tus nqi pub noj ib txwm yog lwm lub teeb liab tsim nyog tshawb xyuas.
Vim li cas tus neeg muab khoom zoo tseem ceeb npaum li cov khoom siv
Paub qhov tseeb alloy tsuas yog ib feem ntawm qhov sib npaug. Lub tshuab tshuab cam khwb cia los ntawm nominally siab chrome cov khoom tab sis ua tiav nrog cov kev kho cua sov tsis zoo tuaj yeem ua tsis tau thaum ntxov. Lub voj voog kho cua sov txiav txim siab seb lub microstructure puas ua tiav nws qhov kev xav tau hardness thiab toughness. Kev ntsuam xyuas metallographic tau lees paub tias cov qauv hauv cov nplej tsis muaj kev sib txuas ntawm cov carbide nkig, uas yog ib qho ua rau pob txha ntxov ntxov.
Ntawm Duma, txhua lub tshuab tshuab thiab crusher hnav ib feem dhau los ntawm tag nrho hauv -cov saw zoo hauv tsev: kev tshuaj xyuas cov khoom siv raw, kev tswj cov tshuaj tua hluav taws xob nrog kev yuam dej, kev tshuaj xyuas metallographic, thiab kev sim ua ntej xa khoom. Nrog ntau dua 4,000 tus qauv pwm ntawm tes thiab muaj peev xwm thim rov qab- engineers los ntawm cov qauv hnav, Duma pab pawg neeg ua haujlwm tuaj yeem sib tw txhua yam HSI crusher ntawm kev ua lag luam, los ntawm Metso thiab Sandvik mus rau Kleemann thiab Terex, nrog rau qhov chaw uas haum thiab ua haujlwm tsis tu ncua los ntawm thawj qhov kev hloov mus rau tom ntej.
Kev xav zaum kawg
Crusher tshuab tuavtsis yog cov khoom siv hloov pauv tau koj tuaj yeem sib pauv yam tsis xav. Cov khoom siv zoo, raug sib raug zoo rau koj cov khoom noj thiab cov theem crushing, yuav ua tau zoo dua cov khoom siv tsis raug los ntawm ib qho ntawm ob mus rau plaub hauv qee qhov kev siv. Qhov kev xaiv tsis raug tsis yog tsuas yog them nyiaj hauv cov khoom hloov pauv. Nws raug nqi lub sij hawm tsim, rotor puas tsuaj, thiab downstream khoom zoo.
Ua haujlwm los ntawm peb - cov txheej txheem xaiv: pub abrasiveness, tramp hlau txaus ntshai, thiab crushing theem.
