Taw qhia rau cement clinker
Cement clinker yog cov khoom lag luam ib nrab ua tiav raws li limestone thiab av nplaum, cov khoom siv hlau yog cov khoom siv tseem ceeb, tsim rau hauv cov ntaub ntawv raw raws li qhov tsim nyog, hlawv kom txog thaum ib feem lossis tag nrho cov molten, thiab tau txais tom qab txias.Hauv kev lag luam cement, cov khoom siv tshuaj tseem ceeb ntawm Portland cement clinker feem ntau yog calcium oxide, silica thiab me me ntawm alumina thiab hlau oxide.Lub ntsiab ntxhia muaj pes tsawg leeg yog tricalcium silicate, dicalcium silicate, tricalcium aluminate thiab hlau aluminate tetracallic acid, Portland cement clinker ntxiv rau qhov tsim nyog ntawm gypsum tom qab sib tsoo tuaj yeem ua rau portland cement.
Kev siv cov cement clinker
Tam sim no, cement clinker tau siv dav hauv kev tsim kho pej xeem thiab kev lag luam, xws li cementing ntawm oilfields thiab gas fields, loj-ntim dams nyob rau hauv dej txuag tej yaam num, tub rog kho tej yaam num, raws li zoo raws li cov kua qaub thiab refractory cov ntaub ntawv, txhaj tshuaj nyob rau hauv tunnels cap. ntawm pit.Tsis tas li ntawd, ntoo thiab hlau tuaj yeem siv los hloov ntoo rau ntau yam kev siv xws li xov tooj ncej, railway sleepers, roj thiab roj pipelines, thiab roj cia thiab roj cia tank.

Kev tsom xam ntawm kev sib tsoo zeb qauv
Vertical roller mills:
Cov cuab yeej loj loj thiab cov khoom tso tawm siab tuaj yeem ua tau raws li kev tsim khoom loj.Qhov noCement Clinker Zebmuaj kev ruaj ntseg siab.Disadvantages: cov cuab yeej siv peev nyiaj siab.
Theem I:Crushing ntawm raw khoom
Qhov lojcement clinkercov khoom yog crushed los ntawm lub crusher mus rau lub pub fineness (15mm-50mm) uas tuaj yeem nkag mus rau hauv kev sib tsoo zeb.
TheemII: Gnkim
Lub crushedcement clinkerCov ntaub ntawv me me raug xa mus rau lub hopper cia los ntawm lub elevator, thiab tom qab ntawd xa mus rau qhov sib tsoo chamber ntawm lub zeb sib npaug thiab ntau npaum li cas los ntawm feeder rau kev sib tsoo.
Theem III:Muab faibhauv
Cov ntaub ntawv milled tau muab qhab nia los ntawm kev muab qhab nia, thiab cov hmoov tsis tsim nyog tau muab qhab nia los ntawm cov khoom faib thiab rov qab mus rau lub tshuab tseem ceeb rau kev sib tsoo.
TheemV: Collection ntawm cov khoom tiav
Cov hmoov ua raws li kev nplua nuj ntws los ntawm cov raj xa dej nrog cov roj thiab nkag mus rau hauv cov plua plav collector rau kev sib cais thiab sib sau.Cov hmoov uas tau sau tiav yog xa mus rau cov khoom tiav silo los ntawm cov khoom siv thauj khoom los ntawm qhov chaw nres nkoj tawm, thiab tom qab ntawd ntim los ntawm cov hmoov tanker lossis tsis siv neeg ntim khoom.
Daim ntawv thov piv txwv ntawm cement clinker hmoov ua
Guilin Hongcheng cement clinker sib tsoo tshuab yog ruaj thiab cov khoom siv thiab cov khoom zoo heev.Ntawm lawv, lub tswv yim ntawm kev tiv thaiv ib puag ncig yog qhov tseem ceeb heev.Cov plua plav pov tseg hauv lub rooj cob qhia pulverizing yog qhov yooj yim heev, tag nrho ib puag ncig yog huv thiab huv si, thiab kev siv hluav taws xob kuj tsawg heev.Qhov no tseem ceeb heev rau cov tuam txhab tsim khoom, uas ncaj qha txo cov nqi tsim khoom thiab kev ua haujlwm thiab txuag nyiaj ntau rau cov lag luam pulverizing.Yog li ntawd, qhov no yog ib lub zeb nrog kev ua tau zoo heev.
