Lub voj voog hloov ntawm lubbimetal kua composite rauj taub hauyog ib qho kev txhawj xeeb uas tau nthuav dav los ntawm cov neeg siv hauv mining, siv cov khoom siv, xuab zeb thiab gravel, thiab crushing industries. Tsis muaj lub voj voog hloov pauv tsis tu ncua, vim nws feem ntau yog nyob ntawm cov khoom siv crushed, cov khoom siv ua haujlwm, cov sijhawm ua haujlwm txhua hnub, thiab cov khoom ntim ntau lawm. Raws li cov ntaub ntawv thov kev lag luam tiag tiag, nws lub voj voog hloov pauv feem ntau yog li ntawm ib nrab ntawm ib hlis mus rau peb lub hlis, ua tau zoo dua li cov khoom siv tib yam - rauj taub hau.
Khoom hardness yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau lub voj voog hloov. Thaum siv rau crushing nruab nrab thiab qis- cov ntaub ntawv hardness xws li limestone, coal gangue, thiab shale, cov ntaub ntawv no ua rau muaj kev cuam tshuam tsawg thiab puas me ntsis ntawm lub taub hau rauj. Raws li kev ua haujlwm tas li ntawm 8 mus rau 10 teev hauv ib hnub, cov kua bimetal sib xyaw rauj lub taub hau feem ntau tuaj yeem ua haujlwm ruaj khov rau 1 txog 3 lub hlis. Nyob rau hauv cov xwm txheej zoo li no, lub taub hau rauj feem ntau ntsib kev hnav khaub ncaws thiab tsis tshua muaj kev cuam tshuam hauv zos los yog tawg. Nws tag nrho siv qhov zoo ntawm cov ntaub ntawv sib xyaw hauv ob qho tib si hnav tsis kam thiab toughness, xa cov kev pabcuam ruaj khov rau lub neej.
Rau siab -hardness thiab abrasive heev cov ntaub ntawv xws li granite, basalt, hlau ore, thiab quartzite, rauj lub taub hau yog raug mob hnyav thiab kev sib txhuam loj heev thaum crushing, uas ua rau kom ceev heev hnav. Txawm hais tias muaj qhov zoo dua ntawm qhov siab -hardness hnav- cov txheej txheem ua haujlwm tiv taus thiab siab -toughness puag lub cev, bimetal kua sib xyaw rauj lub taub hau feem ntau muaj lub voj voog hloov ntawm 15 hnub mus rau 1 lub hlis raws li kev ua haujlwm tas mus li -. Qee cov ntaub ntawv uas muaj cov ntsiab lus silicon siab thiab cov npoo ntse tuaj yeem ua kom nrawm nrawm ntawm qhov chaw ua haujlwm thiab ua kom lub sijhawm hloov me ntsis, tab sis lub taub hau rauj tseem muaj zog dua li hom zoo tib yam.
Ntxiv nrog rau cov khoom siv, cov khoom siv ua haujlwm tseem cuam tshuam ncaj qha rau kev hloov zaus. Lub taub hau rauj tswj kev sib npaug ntawm kev ntxhov siab thiab kev hnav tsis tu ncua thaum lub crusher yog pub tusyees thiab pub dawb ntawm cov khoom txawv teb chaws tsis zoo xws li cov hlau, yog li ua tiav kev ua haujlwm zoo. Cov khoom siv tsis tu ncua, kev cuam tshuam los ntawm cov hlau tsis sib xws, thiab kev thauj khoom ntau dhau tuaj yeem ua rau muaj kev ntxhov siab hauv cheeb tsam ntawm lub rauj lub taub hau, ua rau kev hnav tsis zoo, chipping, thiab lwm yam teeb meem, yog li ua rau lub neej ua haujlwm luv. Lub caij no, cov sij hawm ua hauj lwm txhua hnub kuj yog ib qho tseem ceeb siv. Cov kab ntau lawm khiav 24 teev nyob rau ib hnub ib txwm muaj qhov hloov pauv luv luv dua li cov kev khiav haujlwm tsis tu ncua.
Kev txiav txim siab xav tau kev hloov pauv yuav tsum tsis txhob cia siab rau lub sijhawm nkaus xwb tab sis kuj tseem nyob ntawm qhov ua haujlwm tiag tiag. Kev hloov pauv tau pom zoo thaum qhov chaw ua haujlwm ntawm lub taub hau rauj yuav ua rau thinner, crushing efficiency txo, paug particle loj yuav coarser thiab tsis ruaj khov, los yog me ntsis chipping los yog deformation tshwm. Kev hloov raws sij hawm tsis yog tsuas yog ua kom muaj kev sib tsoo zoo tab sis kuj tseem tiv thaiv lub taub hau rauj ntau dhau los ntawm kev puas tsuaj rau lwm yam khoom xws li lub rotor.
Hauv cov ntsiab lus, bimetal kua sib xyaw rauj taub hau ua tiav qhov sib npaug zoo ntawm qhov tawv thiab tawv los ntawm cov kua sib xyaw tshuab. Raws li kev ua haujlwm zoo ib yam, nws lub neej kev pabcuam yog ntau dua ob npaug ntawm cov tsoos siab -manganese steel rauj taub hau. Nws ua tau zoo txo qis sijhawm rau kev hloov pauv, txo qis kev ua haujlwm thiab cov nqi tsim khoom, thiab muab kev ua haujlwm ruaj khov thiab ntau dua kev lag luam nyiaj txiag rau cov kab ntau lawm.
