I. Qhov koj tuaj yeem pub rau hauv aRaymond Mill Tshuab- nrog cov piv txwv ntawm lub ntiaj teb tiag
Raymond zeb yog tsim rau nruab nrab hardness lossis softer cov ntaub ntawv. Xav txog cov zaub mov uas tsis yog xim hlau, qee yam tshuaj, thiab txawm tias qee cov hlau ore. Tab sis tsis yog tag nrho cov ore. Peb yuav mus txog qhov ntawd.
1. Tsis yog-metallic minerals - qhov no yog qhov chaw zeb khwv tau nws khaws cia
High-hardness khoom (Mohs 6-9):
Yog, nws tuaj yeem ua rau cov no. Tab sis saib koj cov khoom hnav.
Quartz / silica
iav, ceramics, foundry xuab zeb, khoom siv hauv tsev. Quartz yog abrasive. Kuv tau pom ib txheej sib tsoo lub nplhaib dhau 500 teev ntawm limestone tab sis NW nyuam qhuav 200 ntawm quartz. Npaj koj cov peev nyiaj kho mob raws li.
01
Feldspar, calcite
ceramic glazes, iav batch. Feldspar grinds kwv yees. Calcite? Yooj yim.
02
Barite
ib tug hnyav tus neeg sawv cev rau drilling av nkos, ntxiv muab tub lim rau xim. Barite yog mos txaus (Mohs 3-3.5) tab sis hnyav. Koj lub feeder yuav tsum tau tswj qhov ceev, lossis nws yuav txhaws.
03
Fluorite (fluorespar)
metallurgy, tshuaj, kev tsim kho. Grinds zoo, tab sis saib rau plua plav - nws tuaj yeem ua rau mob ntsws.
04
Zircon xuab zeb
refractories, ceramic glazes. Hard (Mohs 7.5). Cia siab tias yuav hnav lub nplhaib nrawm dua.
05
Medium-hardness (Mohs 3-6):
Qhov no yog qhov chaw qab zib.
Limestone / calcium carbonate
feem ntau pub. Cement, fillers, desulfurization. Yog tias koj khiav limestone txhua hnub, Raymond zeb yuav them rau nws tus kheej hauv ib xyoos.
Dolomite- cov khoom siv hauv tsev, iav, ceramics, magnesium smelting. Zoo ib yam li limestone tab sis me ntsis tougher ntawm rings.
06
Dolomite
cov khoom siv hauv tsev, iav, ceramics, magnesium smelting. Zoo ib yam li limestone tab sis me ntsis tougher ntawm rings.
07
Kaolin / bentonite
ceramics, ntawv coatings, thiab drilling av nkos. Bentonite yog qhov nyuaj - nws nqus dej noo thiab o. Khaws koj cov khoom noj kom qhuav, los yog nws yuav tig mus rau hauv paste hauv lub zeb.
Talc- ntawv, txheej, yas, tshuaj pleev ib ce, thiab txawm tias tshuaj. Talc yog nplua. Nws ua taulubricatescov hniav sib tsoo. Rings kav ntev ntawm talc dua li ntawm yuav luag txhua yam.
08
Talc
ntawv, coatings, plastics, tshuaj pleev ib ce, thiab txawm pharmaceuticals. Talc yog nplua. Nws ua taulubricatescov hniav sib tsoo. Rings kav ntev ntawm talc dua li ntawm yuav luag txhua yam.
09
Gypsum
cement retarder, phab ntsa. Grinds zoo li npau suav. Tab sis saib qhov ntsuas kub - gypsum poob nws cov dej siv lead ua siab tshaj 150 degree, thiab koj lub rooj tsavxwm yuav tsis teeb.
10
Chemical raw khoom thiab cov khoom
Phosphate pob zeb
fertilisers, daj phosphorus. Phosphate yog me ntsis abrasive tab sis tswj tau. Qhov teeb meem tiag? Qee cov phosphate ores muaj fluorine. Cov roj ntawd noj cov qauv hlau. Koj yuav xav tau ib daim ntaub uas tiv thaiv corrosion.
Cov pa roj carbon activated
regeneration thiab pulverisation. Nws yog qhuav, plua plav, thiab abrasive. Siv lub tshuab ntsuas pulse, tsis yog cua daj cua dub xwb.
Petroleum coke
aluminium thiab carbon industries. Petcoke grinds zoo, tab sis nws yog flammable. Standard Raymond zeb? Tsis yog. Koj xav tau kev tsim hluav taws xob tawg nrog cov pa roj inert. Kuv tau nyob rau ntawm qhov chaw uas kawm qhov nyuaj no - cov plua plav tawg tau tawm ntawm lub tsev lim.
Pigments thiab coatings
titanium dioxide, hlau oxide repulverization. Cov no yog cov hmoov zoo lawm. Koj tsuas yog rhuav tshem agglomerates. Raymond zeb ua haujlwm, tab sis koj yuav tau siv nyiaj ntau. Xav txog tus pin zeb hloov.
Khoom siv rauRaymond Mill Tshuabs: Hlau thiab Lawv Oxides
Manganese ore, hlau ore, chrome ore, tooj liab ore- pulverized ua ntej kev kho mob metallurgical. Cov no nyuaj (Mohs 5–6.5). Koj tuaj yeem zom lawv, tab sis kev lag luam yog questionable. Lub pob zeb los yog lub tshuab ntsug ntsug yuav zoo dua rau cov hlau ore vim yog tonnage.
Hlau oxides- aluminium oxide, hlau nplai. Alumina nyuaj (Mohs 9). Nws yuav rhuav tshem Raymond zeb lub nplhaib sib tsoo hauv kev ua haujlwm. Tsis txhob ua. Hlau nplai ( zeb nplai) yog softer tab sis muaj hlau hlau - koj yuav tau txais sparks. Teeb meem hluav taws.
II. Dab tsi TSIS tau muab tso rau hauv Raymond zeb - lossis tsawg kawg, tsis yog tsis muaj kev hloov pauv loj
Qhov no cawm koj ntawm kev ua yuam kev kim. Kuv tau saib tib neeg rhuav tshem lub tshuab tshiab tshiab nyob rau ib tav su los ntawm kev pub cov khoom tsis raug.
Cov ntaub ntawv nrog Mohs hardness> 9.3
Piv txwv li: silicon carbide, corundum, pob zeb diamond, sintered bauxite.
Vim li cas ho tsis? Kev sib tsoo cov nplhaib thiab cov chais yog feem ntau high-manganese steel los yog hlau alloy - hardness nyob ib ncig ntawm 8.5 mus rau 9. Pub ib yam nyuaj, thiab koj yeej ib txwm sib tsoo hlau tiv thaiv pob zeb diamond. Cov menyuam yaus hnav hauv cov xuab moos. Koj yuav hloov cov nplhaib txhua 50 teev. Tus nqi tu yuav tshaj tus nqi ntawm cov khoom.
Cov ntaub ntawv nplaum- cov av nplaum ntub, qee cov av nplaum uas muaj viscosity.
Vim li cas ho tsis? Lawv pleev xim rau sab hauv phab ntsa, cov chais, thiab cov hniav cais. Tsis pub dhau ib teev, cov cua ntws nres. Lub zeb chokes. Koj siv sijhawm ib hnub nrog rauj thiab chisel ntxuav tawm cov av nplaum tawv. Kuv twb pom nws tshwm sim. Qhov kho? Qhuav cov khoom kom qis dua 6% noo noo. Los yog siv hom zeb sib txawv (tus pin zeb lossis rauj zeb) uas nws tus kheej ntxuav tau zoo dua.
01
Cov ntaub ntawv fibrous- ntoo chips, xyoob shavings, asbestos.
Vim li cas ho tsis? Fibers tsis tawg nyob rau hauv compression - lawv khoov. Lawv qhwv ib ncig ntawm cov hniav cais thiab cov kiv cua impeller. Tom qab ntawd lub rotor kaw. Los yog qhov nyiaj tshuav ploj mus, thiab tag nrho lub tshuab co zoo li av qeeg. Asbestos? Tsis txhob xav txog nws. Cov plua plav yog carcinogenic, thiab cov txheej txheem zeb tsis raug kaw rau nws.
02
Cov ntaub ntawv corrosive heev- muaj zog acids los yog alkaline tshuaj.
Vim li cas ho tsis? Lawv noj cov hlau. Tsis pub dhau ib lub lim tiam, koj lub tsev zeb yuav muaj cov dej ntws tawm. Koj cov kiv cua ploj lawm. Yog tias koj yuav tsum tau zom cov no, koj xav tau cov hlau tsis muaj steel lossis hnav-resistant lined internals - tab sis qhov ntawd yog triples tus nqi. Feem ntau tsis tsim nyog.
03
Cov ntaub ntawv kub-sensitive- tej yam yas, resins, thiab tsoos suav tshuaj ntsuab.
Vim li cas ho tsis? Ib lub Raymond zeb tau kub. Qhov chaw sib tsoo tuaj yeem yooj yim tshaj 120 degree. Plastics yaj thiab txheej txhua yam. Resins soften thiab tig mus ua nplaum goo. Tshuaj ntsuab poob lawv cov active compounds. Txoj kev daws teeb meem? Zeb nrog cua txias los yog kua nitrogen. Qhov ntawd yog lub tshuab txawv heev.
04
High‑moisture materials (>6%)- dab tsi ntub.
Vim li cas ho tsis? Cov khoom ntub dej txhaws cov khoom noj khoom haus, lo rau lub nplhaib sib tsoo, thiab thaiv cov khoom cais. Lub tshuab tso zis poob mus rau xoom. Ib txwm qhuav koj cov khoom ua ntej. Ib lub tshuab ziab khaub ncaws yooj yim raug nqi tsawg dua li lub sij hawm poob los ntawm kev khawb tawm lub zeb zeb.

III. Yuav ua li cas xaiv txoj cai Raymond zeb rau koj txoj haujlwm
Thaum koj tau lees tias koj cov khoom tsim nyog, tsis txhob xaj tus qauv pheej yig tshaj. Ua haujlwm dhau tsib lub ntsiab lus no.
Khoom hardness
thawj yam. Nws qhia koj sai npaum li cas koj cov khoom hnav yuav hnav. Mill manufacturers tuaj yeem muab koj qhov "hnav ib feem ntawm lub neej" kwv yees hauv tons ib txheej. Rau limestone (Mohs 3), koj yuav tau txais 500 tons ib lub nplhaib teeb. Rau quartz (Mohs 7), tej zaum 80 tons. Khiav tus lej. Yog tias tus nqi hnav ib tuj tshaj koj cov nyiaj tau los, saib ntawm hom zeb sib txawv.
Pub particle loj
Raymond mills xav kom tsawg dua lossis sib npaug li 20-30 mm. Loj dua li ntawd? Koj xav tau ib tug crusher upstream. Kuv tau pom cov neeg pov pob zeb 100 hli rau hauv lub zeb. Lub zeb jams, lub ntsiab ncej shears, thiab koj nyob rau ib lub lim tiam. Nruab lub puab tsaig crusher lossis rauj crusher ua ntej. Nws tsim nyog.
Cov khoom tiav fineness
Feem ntau 80-600 mesh, nrog rau kev teeb tsa tshwj xeeb txog 1000 mesh. Ua ncaj ncees: ua kojtiag tiagxav tau 600 mesh? Finer txhais tau hais tias qis dhau los thiab siv zog ntau dua. Yog tias 200 mesh ua haujlwm rau koj cov neeg siv khoom, tsis txhob over-spec. Koj yuav txuag tau nyiaj.
Moisture thiab viscosity
Yog tias koj cov khoom yog ciam teb ntub dej (5-6%), ntxiv cov cua kub rau hauv lub zeb. Ntau Raymond mills tuaj yeem txais cov cua kub los ntawm kev sib tsoo chamber. Uas dries li nws grinds. Tab sis thaum koj tshaj 8% ya raws, koj xav tau ib lub tshuab ziab khaub ncaws. Tsis muaj shortcuts.
Summary - cov kab hauv qab los ntawm ib tug neeg uas tau nyob hauv lub tshav pob
A Raymond Mill TshuabNws yog ib tug workhorse rau nruab nrab hardness non-metallic - limestone, calcite, barite, kaolin, gypsum, talc. Nws tsis yog universal grinder. Kev vam meej yog los ntawm kev sib piv koj cov khoom hardness, noo noo, thiab stickiness rau lub tshuab tsim txwv.
Ua ntej koj yuav, ua qhov no: xa 50 kg qauv mus rau cov chaw tsim khoom. Nug rau qhov kev xeem grind ntawm koj lub hom phiaj fineness. Tau txais tus nqi tso zis tiag tiag, rub lub zog, thiab hnav ib feem hnav tus nqi. Tsis txhob tso siab rau daim ntawv qhia tus lej. Cia siab rau daim ntawv xeem.
Thiab yog tias koj cov khoom nyob sab nraum qhov tsim nyog? Tsis txhob yuam nws. Muaj lwm cov mills: pob zeb, ntsug mills, rauj mills, dav hlau mills. Xaiv lub cuab yeej tsim nyog rau txoj haujlwm. Koj cov peev nyiaj kho mob yuav ua tsaug rau koj.
