Cov sintered blocks uas tsim nyob rau hauv lub moj tej tawg sintering txheej txheem ntawm txhuas concentrate thiab lead-zinc mix concentrate yog tawg los ntawm ib tug multi- theem crushing txheej txheem. Tom qab thawj ob theem crushing, ib feem ntawm qhov tsim nyog kub sintered blocks yog xa ncaj qha mus rau lub moj tej tawg rauv, thiab feem ntau ntawm cov seem uas tsim nyog sintered blocks thiab cov khoom nyob rau hauv lub screen yog tawg nyob rau hauv ob theem tom ntej los tsim cov khoom xa rov qab uas ua tau raws li qhov yuav tsum tau muaj ntawm qee qhov me me.
Nyob rau hauv xyoo tas los no, nyob rau hauv tus txheej txheem ntawm kev tsim hlau, txhawm rau txhim kho qhov txo qis ntawm qhov cub tawg thiab tiv thaiv kev sib cais, thiab ntxiv dag zog rau kev tsim khoom, qee qhov yuav tsum tau muab tso rau pem hauv ntej rau qhov loj me me ntawm sintered block nkag mus rau hauv qhov cub tawg, yog li cov txheej txheem ntau- theem crushing kuj tau txais. Lub Oita Thawj sinter cog, tshiab tsim thiab muab tso rau hauv Nyiv xyoo 1972, xav kom cov sintered block loj rau hauv lub qhov cub tawg tsis pub tshaj 35 hli, thiab txais yuav peb -theem crushing txheej txheem, thiab qhov zoo sintering cheeb tsam ntawm lub tshuab sinter yog 5 × 80 meters 2.mineral sizersmuaj peev xwm tswj tau qhov tsim nyog block loj, yog li lawv tau siv nyob rau hauv lub thib ob theem crushing.
Niaj hnub nimno loj - nplai refineries xav tau kev tsim khoom txuas ntxiv ntawm sintering systems. Qhov kub ntawm sintered block nyob rau hauv cov ntxhia sizers tuaj yeem ncav cuag 650 ~ 750 degree, thiab kev ua haujlwm hnyav heev. Vim tias qhov kub thiab txias ntawm cov sintered thaiv thiab cov cuab yeej abrasive, cov hniav phaj ntawm lub crusher yog heev yooj yim mus hnav, uas cuam tshuam rau kev ua haujlwm ntawm lub crusher. Yog li ntawd, nws yog ib qho tsim nyog yuav tau nrhiav ib yam khoom uas muaj siab hnav tsis kam mus rau qhov kub thiab txias sintered thaiv, thiaj li yuav ua kom ntev kev pab cuam lub neej ntawm lub crusher hniav phaj; Ntawm qhov tod tes, nws kuj tseem yuav tsum tau siv lub detachable hniav phaj txuas qauv kom haum rau cov hniav phaj tuaj yeem yooj yim thauj khoom thiab tshem tawm thiab hloov. Txhawm rau kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm bearings, yuav tsum tau siv zog los txo lossis tshem tawm qhov cuam tshuam ntawm cov khoom kub ntawm cov bearings. Vim hais tias lub crusher ua haujlwm nrog kev cuam tshuam thiab kev vibration, qhov hloov pauv ntawm lub zog loj heev, yog li ntawd lub zog sab nraud ntawm cov hniav yob tau nce ntau, yog li nws yog ib qho tsim nyog yuav tsum tau ntxiv ib qho txuas hauv qhov system uas tuaj yeem txo qhov cuam tshuam ntawm kev vibration siab. Nyob rau hauv tus txheej txheem ntawm sintering ntau lawm, nws yog inevitable uas txawv teb chaws teeb meem yuav nkag mus rau hauv lub crusher. Txhawm rau kom txo qis "cov menyuam" tsis ua haujlwm, cov pob zeb hauv av yuav tsum muaj "kev muaj peev xwm txawv teb chaws". Thiab txhawm rau tiv thaiv "cov menyuam" tsis ua haujlwm los ntawm lub zog muaj zog dhau los ntawm kev txaus ntshai. Peb cov pob zeb loj loj ntawm kub sintered blocks tsim rau peb cov neeg siv khoom hauv Shandong refinery tau ua tiav zoo los daws cov teeb meem saum toj no thiab tau ua pov thawj los ntawm ntau xyoo ntawm kev tsim khoom thiab kev ua haujlwm hauv cov nroj tsuag.
Lub ntsiab ntsuas los txhim kho qhov hnav tsis kam ntawm cov hniav phaj yog ua kom cov tawv nqaij ntawm cov hniav. Yog li ntawd, cov khoom uas tseem muaj qee yam "liab hardness" nyob rau hauv kev ua haujlwm ntawm 650 ~ 700℃yog xav tau. High manganese austenitic steel yog ib hom kev tiv thaiv siab - cov khoom siv, uas yuav ua rau ua haujlwm sai sai thaum muaj kev cuam tshuam thiab siab. Txawm li cas los xij, tom qab cov khoom no yog toughened los ntawm dej, thiab ces reheated rau 550 ~ 750 degree, cov carbide yaj nyob rau hauv austenite yog precipitated dua, thiab lub toughness thiab plasticity ntawm cov hlau yog sharply txo, uas ua rau nyuaj thiab nkig phenomenon. Vim tias chromium yog ib qho muaj zog carbide tsim cov ntsiab lus, ntxiv cov nyiaj tsim nyog ntawm chromium rau siab manganese hlau yuav tsum tau txhim kho nws "liab hardness". Chromium manganese austenitic steel yog qhov kub thiab txias los tiv thaiv - oxidation steel, tom qab cov khoom siv kho mob muaj qhov kub thiab txias, tab sis nyob rau hauv qhov kev txiav txim siab kub ntev ntev, vim "theem ob" nag lossis daus thiab thermal embrittlement, tshwj xeeb tshaj yog nyob rau hauv thaj tsam ntawm 800 ~ 900℃yog qhov khaus tshaj plaws. Kev ua haujlwm kub ntawm cov hniav txhuam hniav yog 650 ~ 700 degree, thiab peb tswj cov ntsiab lus ntawm chromium thiab silicon hauv cov khoom raws li qhov qis qis, txhawm rau cia siab tias nws yuav muaj ob qho tib si lub hnub nyoog tawv thiab tawv, thiab tswj kom tsim nyog toughness. Ua kom tag nrho cov kev laus brittleness ntawm cov hniav phaj cov ntaub ntawv nyob rau hauv kev ua hauj lwm tej yam kev mob ntawm cov hniav yob los txhim kho cov hnav tsis kam ntawm thermal khoom, yog li peb xaiv ob hom ntaub ntawv. Tom qab ob xyoos ntawm kev siv nyob rau hauv ntau lawm, cov nyhuv yog zoo, qhov nruab nrab hnav ceev ntawm crushing phaj hniav tsis pub tshaj 1 (mm / hli). Cov hniav yob muaj yim-sab yob lub cev thiab lub phaj tshem tawm tau. · Lub crushing hniav phaj thiab yob lub cev yog txuas nrog bolts. Cov bolts thiab txiv ntseej yog ua los ntawm qis-carbon chrome-molybdenum pearlite hlau los tiv thaiv kev sib txuas los ntawm kev xoob vim kev ntxhov siab. Txhawm rau them nyiaj rau thermal deformation, lub caij nplooj ntoos hlav phaj ntxiv rau qhov sib txuas bolted.
Nyob rau hauv kev saib ntawm cov yam ntxwv ntawm lub sij hawm loj ntawm inertia xws li cov ntxhia sizers, thiab cov kev cai txhim khu kev qha ntawm dynamic overload tiv thaiv, lub sij hawm - txwv hydraulic coupling yuav tsum muaj tag nrho -poob lwm yam ntxwv, uas yog, sab xis ntawm qhov tseem ceeb point yuav tsum ntxhab, sab laug ntawm qhov tseem ceeb taw tes rau lub low speed ratio hloov mus rau gradient tus yam ntxwv, thiab cov braking point yog ze rau tus nqi ntawm qhov ntsuas taw tes. Txhawm rau txhawm rau ua tiav cov yam ntxwv sab nraud no, lub voj voog tsis sib xws ntawm lub sijhawm - txwv hydraulic coupler tuaj yeem siv. Rau lub zog ntau yam ntawm cov ntxhia pob zeb uas xav tau los ntawm qhov loj - nplai sintering tshuab siv tam sim no, kaw tus kheej -txias aluminium alloy qauv tuaj yeem siv rau hydraulic coupling, uas yog tsim nyog rau cov yam ntxwv ntawm ib qho - daim ntau lawm, thiab yooj yim thiab txhim khu kev qha.
