Hauv cov chaw mining, qhov hnyav ntawm alub khob hliav qab crusher mantleyog ib qho tseem ceeb heev technical parameter. Nws ncaj qha txiav txim siab txog kev ncaj ncees ntawm cov khoom siv, lub zog crushing siv rau cov ore, thiab kev ruaj khov ntawm cov txheej txheem crushing. Kev nkag siab meej txog qhov hnyav ntawm lub mantle yog qhov tseem ceeb rau cov dej num hauv qab no: stabilizing lub tshuab, tso cai rau lub hauv paus crusher thiab lub hauv paus kom muaj zog kom lub tshuab yuav tsis co ntau dhau los yog txawm tawg thaum lub sijhawm ua haujlwm; pab xaiv cranes, txij li lub mantle thiab nws cov khoom feem ntau hnyav hauv tons thiab xav tau cranes thaum hloov, ua kom zoo dua crane xaiv thiab txo qhov kev pheej hmoo nqa; Saib xyuas cov nyhuv flywheel thaum lub sijhawm ua haujlwm tshuab los ntsuas kev ua haujlwm ntawm crushing.

Txhawm rau kom ntseeg tau tias cov khoom hnyav no nruj me ntsis raws li cov lus qhia meej saum toj no, lub chaw tsim khoom mantle Duma tau nruab nrog lub hauv paus loj sib xyaw ua ke npog 42,000 square meters. Los ntawm tag nrho - txheej txheem kev tswj hwm ywj pheej (los ntawm kev tshuaj xyuas cov khoom siv raw mus rau qhov kawg machining), Duma tuaj yeem ua kom txhua qhov kev ua tau raws li qhov hnyav thiab qhov ntev ntev uas xav tau los ntawm cov khoom lag luam thoob ntiaj teb xws li Metso thiab Sandvik.
Yam khoom twg yog qhov hnyav tshaj?
Lub mantle yog tsim los ntawm mantle liner, concave, thiab xauv txiv ntoo. Ntawm cov khoom no, lub mantle liner yog qhov hnyav tshaj plaws, ua raws li qhov concave. Raws li cov ntaub ntawv pov thawj ntawm Sandvik thiab Metso, lub mantle ntawm Sandvik CH440 hnyav 643.65 kg, thaum lub concave ntawm tib qauv thiab kab noj hniav hom hnyav kwv yees li 500-600 kg; Lub mantle ntawm Metso GP300S hnyav 962.9 kg, thaum lub concave ntawm tib qauv hnyav 881 kg.
Duma cone crusher mantle thiab concave
Lub "mantle" tsis yog ib qho kev tivthaiv, tab sis ib qho kev sib dhos ntawm ntau qhov tseem ceeb, suav nrog lub cev lub cev, lub cev lub cev, lub cev lub cev, lub qhov rooj xauv, thiab lwm yam. Cov khoom siv no ua haujlwm ua ke los ua kom tiav cov txheej txheem crushing, thiab tag nrho qhov hnyav yog faib rau ntau qhov tseem ceeb:
Lub khob hliav qab crusher mantlethiabconcave lineryog cov tub ntxhais hnav-cov ntaub uas tiv taus. High-cov ntaub ntawv zoo yog ua los ntawm siab- ntom ntom siab-manganese hlau (Mn13, Mn18, lossis Mn22). Cov khoom siv no muab cov khoom loj uas yuav tsum tau ua rau crushing nyuaj ore thaum tuav cov qauv kev ruaj ntseg.
Lub khob hliav qab crusher mantle locking txiv ntseej, txawm tias me dua li lub mantle liner, yog ib qho hnyav -lub luag haujlwm tshwj xeeb fastener. Cov txiv ntoo xauv yuav tsum xyuas kom meej haum los ntawm precision machining kom nws thiaj li tsis txhob loosening ntau npaum li sai tau nyob rau hauv kev co hnyav.
Cov txheej txheem hauv paus loj suav nrog cov khoom siv hauv lub cev uas siv los txhawb nqa tag nrho cov kab. Nws raug pom zoo tias cov khoom siv tau raug tswj xyuas kev kho cua sov (dej toughening), uas ua kom muaj cov qauv austenitic ruaj khov thiab ua rau lub rooj sibtham hnyav los tiv thaiv cov pob txha tawg. Duma ua raws li txoj hauv kev no.
Lub mantle yuav tsis tu ncua poob loj thaum lub pob zeb crushing txheej txheem, thiab qhov poob yog feem ntau mus txog 15% -25% ntawm thawj qhov hnyav. Cov neeg ua haujlwm cia siab rau qhov sib xws ntawm kev ua haujlwm casting los kwv yees lub voj voog hloov. Yog hais tias nruj heev - magnification metallographic tshuaj xyuas thiab tsis yog - kuaj kev puas tsuaj (ultrasonic / magnetic particle test) tuaj yeem ua tau, ces qhov kev ruaj ntseg no tuaj yeem lav tau zoo dua, thiab qhov ua tau ntawm lub cev pob txha ntxov ntxov tshwm sim los ntawm kev puas tsuaj sab hauv yuav raug txo kom tsawg. Kev nthuav qhia qhov hnyav ntawm qhov hnyav yog qhov tsim nyog ua ntej rau kev ua haujlwm nyab xeeb. Txawm hais tias nws yog ib hom khoom lag luam- lub tsho tshiab los yog cov khoom siv pov tseg, pab pawg nqa yuav tsum siv cov cuab yeej muaj ntawv pov thawj rau kev ua haujlwm. Los ntawm qhov tseeb -tsim mantle locking txiv ntoo mus rau lub mantle loj thiab concave sib dhos, qhov hnyav yog qhov taw qhia tseem ceeb rau kev ntsuas lub peev xwm crushing.
Yog tias koj tab tom nrhiav rau tus khub zoo crusher spare qhov chaw, txais tos kom paub txog Duma. Duma muaj batch traceability tag nrho, muab 12-hli warranty, thiab tuaj yeem ua kom muaj kev nyab xeeb, ruaj khov thiab ua haujlwm zoo ntawm cov khoom siv hnyav. Rau cov qauv siv feem ntau,Dumakuj tseem muaj cov khoom lag luam loj, nrog rau kev xa khoom sai tshaj plaws hauv 7-10 hnub[4].
