Thaum xaiv cov khoom sib tsoo lossis sib tsoo, ib qho tsis tuaj yeem tsuas yog "kev txiav txim raws li daim duab"; es, nws koom nrog kev sib sib zog nqus sib sib zog nqus ntawm cov khoom siv hauv nruab nrab ntawm cov khoom siv thiab cov khoom siv ntawm cov tshuab shearing. Yog tias cov hauv paus ntsiab lus crushing yog qhov tsis sib haum xeeb - rub tawm cov lus qhia tawm, raws li nws tau ua - ces txawm stacking lub cev muaj zog loj npaum li cas rau tsis muaj dab tsi ntau tshaj li kev siv hluav taws xob pov tseg thiab khiav tsis ua haujlwm.
Raws li lub caij nyoog kev lag luam sab hauv tob tob hauv kev tsim khoom siv tshuab, kuv xav kom ua ntej tawm ntawm "kev txiav txim siab lub zog" thiab hloov mus rau qhov teeb meem raws li peb hom khoom siv.
Ua ntej, thaum ntsib siab - fiber ntau, tawv, thiab tawv tawv cov ntaub ntawv- "cov txiv ntoo tsis muaj zog" (xws li cov ntoo khib nyiab, qoob loo stalks, tshuaj suav tshuaj ntsuab, plaub, los yog cov khoom pov tseg) -tsis * tsis * poob rau qhov hype ib puag ncig "siab {{3}." Txoj kev ntawd yog qhov tsis muaj txiaj ntsig thiab kev siv dag zog tag nrho.
Cov ntaub ntawv no muaj qhov tsis zoo tseem ceeb: lub peev xwm siab tshaj plaws rau elastic deformation. Thaum lub hammerhead ntaus lawv, lub zog kinetic yog tam sim ntawd "absorbed" los ntawm cov khoom; nws zoo li xuas nrig ntaus paj rwb- cov khoom tsis kam ua txhaum. Qhov kev daws teeb meem yog nyob rau hauv kev siv *shear force*- siv cov hniav los "txiav" lossis "tua" los ntawm cov khoom. Hauv kev lag luam, qhov no yog hu ua "shear-hom crushing"; Lub hauv paus ntsiab lus yog zoo ib yam rau ntawm daim ntawv txiav los yog txiab, cia siab rau cov staggered kev sib raug zoo ntawm cov npoo los txiav cov fibers.
Tswv yim tswv yim: Rau peb cov ntoo shredders, peb siv coj-cov hlau alloy steel hniav nrog adjustable clearances. Thaum ua cov plaub, peb pom zoo kom ua ob- txheej txheem theem- ntxhib shredding ua raws li kev sib tsoo zoo- raws li cov ntaub ntawv fluffy txwv tsis pub yuav "choj" thiab txhaws lub tshuab. Tsis tas li ntawd, tsis txhob caum lub rubey ntau dhau; linear tshaj tawm ntawm 25-30 m / s muab kev ua haujlwm ruaj khov tshaj plaws, qhov ceev uas siab dhau yuav ua rau txoj siv hlua khi.Kev pom zoo: Xaiv ib qho ntoo chipper
Thib ob, rau cov khoom siv tawv tawv thiab tawv heev- "cov pob txha tawv" (xws li cov pob txha pob txha, pob zeb ntxhia, limestone, pob kws qhuav, lossis cov nplej nplej)-thaum lawv yuav zoo li ntshai, lawv yeej muaj qhov tsis muaj zog txaus: lawv muaj kev cuam tshuam rau "tshaj" lossis kev vibration.
Tsis txhob raug hem los ntawm compressive lub zog ntawm cov ntaub ntawv no -txawm lawv hnyav npaum li cas, lawv tsuas tsis tuaj yeem tiv taus siab - zaus cuam tshuam.Nyem rau Kawm Ntxiv Txog Coal Crushers
Sim noj rauj thiab ntaus nws nrog tag nrho lub zog; nws yuav tawg tam sim ntawd. Qhov ntawd yog qhov tseem ceeb ntawm " brittleness ."
Yog li ntawd, thaum soj ntsuam nrog cov khoom siv no, lub rauj crusher yog qhov kev daws teeb meem. Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm yog ncaj nraim: siab - ceev rotating hammers xa sai, ua tiav tshuab, ua rau cov khoom ricochet rov qab ntawm cov phab ntsa sab hauv ntawm lub crushing chamber thiab lub vijtsam kom txog thaum nws tag nrho pulverized.Nyem rau Kawm Ntxiv Txog Hammer Mills
Tam sim no, rau qee qhov kev nkag siab txog kev tshaj lij:
Txoj kab nrawm ntawm lub taub hau rauj yuav tsum siab txaus -feem ntau, nws yuav tsum tau tswj kom tsis tu ncua ntawm 80 thiab 100 meters ib ob. Yog tias nws poob qis dua qhov no, lub zog cuam tshuam tsis txaus; conversely, yog hais tias nws yog siab dhau lawm, lub hwj chim noj thaum lub sij hawm tsis muaj -load ua hauj lwm skyrockets, ua rau txo qis rov qab.
Txawm li cas los xij, muaj qhov tsis txaus ntseeg tseem ceeb: cov dej noo ntawm cov khoom yuav tsum * tsis txhob * tshaj 12%. Yog tias nws ua li ntawd, lub vijtsam apertures yuav ua rau txhaws, thiab lub peev xwm ntau lawm yuav raug txiav tam sim ntawd ib nrab. Kuv tau pom ntau qhov me me - teev ua haujlwm tsis quav ntsej cov lus ceeb toom no, muab cov khoom ntub dej pov tseg rau hauv lub tshuab tsuas yog kom nws "kho" li ntawm ib nrab teev; Thaum disassembly, qhov screen pom tau tias tag nrho cov ncuav qab zib, saib zoo li nws tau smeared nrog pob zeb.
Tsis tas li ntawd, tom qab siv sijhawm ntev, kev hnav tsis sib xws ntawm cov rauj daim hlau yog tus qauv. Thaum qhov no tshwm sim, lub tshuab pib vibrate eccentrically, hluav taws xob tam sim no fluctuates wildly, thiab txawm lub bearings raug kev puas tsuaj. Txoj kev kho yog dab tsi? Ib ntus tig lub rauj daim hlau siv rau sab nraub qaum, lossis tsuas yog hloov tag nrho cov teeb. Tsis txhob sim skimp ntawm tus nqi no.
Cov rauj daim hlau suav nrog cov khoom siv txheem ntawm peb lub chaw ua haujlwm tau txais kev kho mob tshwj xeeb carburizing thiab quenching. Nyob rau hauv luv luv, lawv muaj txaus hardness yam tsis muaj kev txi toughness. Raws li kev ua haujlwm ib txwm muaj, lawv lub neej kev pabcuam yog ob npaug ntawm cov rauj zoo tib yam. Tsuas yog ua lej: koj txuag nyiaj ntau npaum li cas- raws li cov nqi zog txo qis thiab txo qis qis dua -los ntawm kev zam tsuas yog ib qho rauj hloov pauv?
Thib peb, thaum cuam tshuam nrog "cov neeg siv khoom nplaum"- cov khoom muaj roj thiab qab zib (xws li noob hnav, walnuts, txiv laum huab xeeb, hnub qhuav, lossis goji berries)- koj yuav tsum nruj nruj koj tus kheej: *tsis txhob * siv lub siab -pulverizer ceev. Ua li no yuav ua rau lub tshuab ntes thiab txhaws tam sim ntawd.
Cov logic yooj yim: siab - kev sib txhuam ceev ua kom muaj cua sov sai sai; Thaum cov roj thiab qab zib ntsib cov kub kub no, lawv yaj tam sim ntawd, tag nrho clogging lub vijtsam mesh. Nws tsis yog tsis yooj yim rau lub cev muaj zog overload thiab hlawv tawm raws li qhov tshwm sim. Kuv ib zaug pom ib tug neeg sim ua txiv laum huab xeeb siv lub tshuab pulverizer; lub tshuab pib haus luam yeeb, thiab thaum disassembly, peb pom tias rauj cov hniav thiab cov tshuaj ntsuam tau fused ua ke rau hauv ib qho khoom loj ntawm melted qab zib thiab roj.Nyem kom paub ntau ntxiv txog stainless hlau pulverizers.
Txoj hauv kev kom raug yog siv ob npaug - cov menyuam zeb zeb (uas tso siab rau kev sib txhuam es tsis yog kev sib txhuam, yog li ua kom tsis muaj cua sov) los yog siv lub tshuab tsis muaj steel hlau uas muaj dej - lub tsho txias. Cov dej txias txias yog tshem tawm cov cua sov sib txhuam, ua kom qhov kub thiab txias hauv chav sib tsoo hauv qab 40 degree. Rau cov chaw tsim khoom noj qab haus huv, peb tau muab 316L stainless hlau dej -cooled pulverizer muaj peev xwm ua cov kua txiv hmab txiv ntoo nyoos mus rau qhov zoo ntawm 80 mesh, khiav tsis tu ncua rau yim teev yam tsis muaj clogging. Nco ntsoov: rau roj- cov qoob loo nplua nuj, nws yog qhov zoo tshaj rau ua ntej- rho cov roj los yog khov cov khoom kom nws nkig; txwv tsis pub, txawm tias tus neeg ua haujlwm txuj ci tseem ceeb yuav tawm tsam los ua lawv.
Ib lo lus kawg ntawm cov lus qhia: tsis txhob cia siab rau ntawm "kev muaj peev xwm theoretical" uas teev nyob rau hauv cov khoom siv cov kev qhia tshwj xeeb -cov duab no feem ntau yog muab los ntawm "cov ntaub ntawv txheem" xws li pob kws lossis nplej. Hloov chaw, xa koj cov qauv rau peb kom khiav 30-feeb sim ntawm lub tshuab; saib xyuas qhov tseeb fineness ntawm cov zis, stability ntawm cov hluav taws xob tam sim no, thiab smoothness ntawm cov paug ntws. Qhov no yog txoj cai golden rau kev xaiv cov cuab yeej zoo.
