Hauv kev ua haujlwm ntawm lub khob hliav qab crusher, cov kab noj hniav crushing yog qhov chaw tseem ceeb uas cov khoom siv crushing tshwm sim. Qhov zoo ntawm nws tus qauv tsim ncaj qha cuam tshuam rau tag nrho kev ua haujlwm ntawm kev ua haujlwm thiab kev lag luam ntawm lub tshuab. Raws li 16 xyoo dhau los ntawm kev tsim khoom crusher spare qhov chaw thiab cov lus tawm tswv yim los ntawm cov neeg siv khoom thoob ntiaj teb, Duma tau sau tsab xov xwm no txog kev cuam tshuam ntawm lub khob hliav qab crusher kab noj hniav tsim ntawm crushing kev ua tau zoo. Peb cia siab tias nws yuav muab cov lus qhia tseem ceeb thaum xaiv lub khob hliav qab crusher spare qhov chaw.

Qhov chaw tsim ntawm sab nrauv ntawm lub khob hliav qab txav (mantle) thiab sab hauv ntawm lub khob hliav qab (concave) yog hu ua lub crushing kab noj hniav. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub khob hliav qab crusher yog tias lub mantle, mounted ntawm lub ntsiab ncej, ua ib tug gyratory swinging tsab ntawv tsa suab. Cov khoom nkag mus rau qhov chaw no yog raug compression thiab sib tsoo ntawm lub khob hliav qab crusher mantle thiab concave, yog li ua tiav crushing.
Qhov zoo ntawm crushing kab noj hniav tsim muaj qhov cuam tshuam loj rau cov kev qhia tseem ceeb thiab kev lag luam, xws li kev tsim muaj peev xwm, kev siv hluav taws xob, cov khoom me me, particle shape, thiab liner hnav. Yog li ntawd, tsis hais hom kab noj hniav, qhov tsim ntawm cov kab noj hniav crushing yuav tsum ua tau raws li cov cai hauv qab no:
- Xyuas kom meej tias qhov yuav tsum tau muaj peev xwm ntawm lub crusher tiav;
- Xyuas kom meej tias cov khoom me me raws li cov kev qhia tshwj xeeb - muab qhov tsim nyog fineness, uniformity, thiab particle shape;
- Tiv thaiv cov khoom thaiv cov khoom - kab noj hniav qauv yuav tsum tso cai rau cov ntaub ntawv du thiab tsis txhob "choking";
- Ua kom tau raws li cov khaub ncaws hnav zoo li ua tau - kom ntseeg tau tias hnav txawm tias hnav ntawm ob lub khob hliav qab crusher mantle thiab concave liner kom ntev kev pab cuam lub neej.

Cov qauv kab noj hniav thaum ntxov yog feem ntau ua raws li cov xwm txheej geometric zoo tagnrho. Cov "theoretical" designs overlooked lub tiag tiag hnav qauv ntawm liners nyob rau hauv tiag tiag - ntiaj teb no ua hauj lwm. Kev kos duab los ntawm Duma qhov kev tsim khoom dav dav, peb tau pom tias hauv kev tsim khoom tiag tiag, hnav raws qhov siab ntawm cov kab noj hniav tsis sib xws. Kev hnav tsis sib xws feem ntau ua rau muaj kev puas tsuaj loj tshaj plaws ntawm lub mantle thiab concave tshwm sim ntawm qhov qhib qhib thiab tso tawm. Qhov no ua rau muaj kev cuam tshuam tsis zoo:
- Cavity puab distortion: Qhov chaw crushing tiag deviates los ntawm tus thawj tsim geometry;
- Kev ua haujlwm tsis zoo: Txo cov khoom siv, nce cov khoom siv thauj khoom, ua kom cov khoom tsis zoo, thiab kev siv zog ntau dua.
Txhawm rau daws cov teeb meem no, niaj hnub cone crusher kab noj hniav tsim tam sim no hais txog kev txhim kho ntawm hnav-cov kab noj hniav tiv taus raws li qhov tseeb liner hnav nkhaus. Qhov kev tsim qauv no cia siab tias yuav hnav cov qauv ua ntej, tso cai rau cov hnab ntim khoom kom muaj cov duab geometric tsim nyog rau lub sijhawm ntev dua hauv lawv lub neej kev pabcuam. Raws li qhov tshwm sim, cov ntsuas kev tsim khoom tseem nyob ruaj khov, thiab qhov zaus ntawm kev poob qis rau kev hloov cov kab hluav taws xob tau txo qis.

Tau kawg, los ntawmDuma's manufacturing foundations, ntxiv rau optimizing lub geometric duab, kev xaiv ntawm lub khob hliav qab crusher mantle khoom (xws li siab manganese steel Mn13, Mn18, los yog qib siab dua) kuj tseem ceeb heev rau kev txiav txim siab hnav tsis kam.
Thaum kawg, rov qab mus rau peb cov lus nug qub:Qhov tseem ceeb npaum li cas yog qhov cuam tshuam ntawm lub khob hliav qab crusher tsim ntawm lub crusher?Nws feem ntau yog nyob ntawm seb peb puas paub qhov cuam tshuam ntawm kab noj hniav tsim ntawm crushing efficiency, thiab seb peb kho cov kab noj hniav profile raws li cov lus qhia ua haujlwm tiag tiag kom txo qis qis qis qis los ntawm cov kab noj hniav tsis zoo.
Yog tias koj muaj teeb meem los ntawm qhov tsis tsim nyog cov nqi pov tseg vim muaj teeb meem crusher, xav tias dawbhu rau Duma. Peb tuaj yeem kho qhov tsim nyog tshaj plawscone crusher mantle thiab concaverau koj.
