Rau cov ua muaj pob zeb thiab lwm yam minerals tawm, Nws yog tsim nyog siv tib lub cev thiab tsis pub dhau uas npaj txhua zaus yuav tsum tau txo kev loj.
Haujlwm uas cov loj tawm kev txiav yog tau los ntawm lub cev txhais tau tias yog hu ua crushing thiab kev sib tsoo. Cov cim cov hom ntawv nyob muaj dab, raws li pom nyob rau hauv txoj kev raug cov MAAs hauv thawj tshooj – Cov zaub mov muaj.
Cov cim no tau thiaj li yuav pab txhawb tus ntoo ntawm cov ntaub ntawv, lub cev haujlwm (xws li nws, ntau npaum, agglomeration los yog kev xaus lub neej sai) thiab pab txhawb los yog pab kom haum tshuaj (yog li ntawd tias cov tshuaj tiv thaiv twg yog ib tug muaj nuj nqi ntawm tus nplaim tus hais li thiab yog ob leeg uas loj tshaj qhov dua yog lawv kawm ntawv ntawm cov lus).
Txawm yog muaj clear txawv lub crushing thiab kev sib tsoo, feem ntau hais lus rau crushing thaum hais ntawm qhov ntau thiab tsawg loj yog fragmented rau 1 nti (1") (metric thiab kev kawm lus Askiv cov chav nyob tej zaum yuav siv li siv cov manuals thiab cov catalogues mas muaj heev rau txoj kev loj hlob ntawm qhov teeb meem uas qhov tseem ceeb expressed hauv kev kawm lus Askiv rau lwm) thiab zom dealt muaj particle ntau thiab tsawg tsawg tshaj li 1" (1" = 2.54 cm).
Trituration no tseem disintegration thiab cov khoom uas yuav ua tau rau cov crushers, disintegration, tsi kev tswj los yog txhaum raws li kev cais.
Theem uas crushing
Tus breakup yog kwv nyob rau theem thiab cov cav tov ntau. Li no cov khoom no muab rho tawm los ntawm lub chaw txua txiag zeb thiab tias nws yog ib tug crusher, nyob rau qib no yuav yog tus thawj crushing. Yog tias muaj cov khoom uas ua tiav niam txiv ib tus thib ob shredder, Qhov no yog mob cov theem nrab crushing. Yog tias tseem crushing nyob rau lwm lub cav, lub tertiary, lwm yam.
Qhov ntau thiab tsawg Particle
Ob lub ntxhia los yog muab rho tawm los ntawm lub chaw txua txiag zeb raws li lawv yuav raug kev nyuaj theem ib lossis ntau tshaj ntawm cov txo zeb, Nws yuav tau txwv kom muab zais raws li lawv lub cev me. Hais txog, lawv cov dej num nram qab no txoj kev:
• Khoom tuab: Cov loj tshaj 75 cm (30").
• Medium khoom: tus loj hauv daim 10 mus 75 cm (4" mus rau 30").
• Khoom zoo: cov ib qib qis dua 10 cm (4").
Rau lwm cov tes, Raws li tus me me ntawd tau hais tawm ntawm koj cov cuab yeej siv disintegration , yuav tau distinguished qhov ntau theem ntawm crushing thiab kev sib tsoo. Ces tseem zoo li qub:
mus) Crushing (tsis paub breakup)
• Crushing ntxhib – qhov ntau thiab tsawg uas hais txog cov zis: 15 cm (6").
• Medium shredding – qhov ntau thiab tsawg uas hais txog cov zis: ntawm 3 y15 cm (1¼" 6").
• Nplua crushing – qhov ntau thiab tsawg uas hais txog cov zis: ntawm 0.5 thiab 3 cm (1/5" 1¼").
b) Zom (zoo disintegration)
• Kev sib tsoo ntxhib – qhov ntau thiab tsawg uas hais txog cov zis: ntawm 0.1 thiab 0.3 hli.
• Zom mos – qhov ntau thiab tsawg uas hais txog cov zis: tus menyuam yaus 0.1 hli.
Cov nyiaj crushing, nruab nrab thiab zoo sib, suab, mus thawj, thib ob thiab peb crushing tsis nyob ntev; Thaum sib tsoo nws ntxhib thiab zoo sib haum mus rau tus thawj coj thiab lwm yam theem ntawm kev sib tsoo.
qhov tseeb, hauv daim ntaub ntawv roos poob lawm ntawm tib, Yog li ntawd nws yuav tsis yooj yim sua, ntawm tus muaj pom, xyaum ntsuam raws li saum toj no.
Nyob hauv txoj kev ua lag luam, Kuv yuav ua li cas yog raws li hauv daim nrog ib series sieves (los yog ib qho screen) thiab, Raws li lub qhov ntawm qhov ntau thiab tsawg hauv sab cib, Yog koj equate tau raws cua ces tej qhov ntau thiab tsawg li lawv kis tau los yog tsis yog txhua sab cib.
Teeb disintegration
Qhov yuav txo coefficient tau nyob rau hauv cov khoom crushing (crushers) zom (Mills) hu ua disintegration lub teeb thiab txhais tias yog tus piv ntawm qhov ntau thiab tsawg ntawm tus hais rau tus nkag thiab tawm hauv lub tshuab.
Nquag, yuav txo tau qhov uas muaj peev xwm crusher los yog sprayer yuav tsis txaus kom tag nrho cov disintegration yam, Dab tsi yuav tsum nyob rau theem ob los sis ntau tshaj (thawj crushing, lwm yam, tertiary, thiab lwm yam., thiab zom thawj, lwm yam, thiab lwm yam.)
Cov yam ntxwv ntawm cov pob zeb
Tus yam ntxwv ntawm cov pob zeb no muab rau peb ib lub tswv yim no hais txog tus cwj pwm expected crushing thiab sib tsoo haujlwm. Muaj ntau yam hais txog cov yam ntxwv: hardness, kuj mus ntau stresses, ib phaus, teeb vaum, hom thiab qib grain, lwm yam.
Hardness, Piv txwv, txiav txim seb txoj kev sai ntawm disintegration mus ua raws li cov. Cov ntaub ntawv cov dej num hauv:
• huam (Pob zeb diamond)
• nyuaj (Granite, Quartz)
• Media (limestone, Dolomite)
• mos (plaster, TALC)
Tus heev nyuab zog looj lom thiab yuav tsum tau disintegrated los crushers uas ua hauj lwm rau crush thiab poob siab. Cov tawm thiab muag muag kuj yuav kho tau los ua hauj lwm los muab tshuaj ntxuav thiab crushing.
Vaum yog lwm feature tseem ceeb heev vim nws yuav ua rau koj yuav txiav txim siab, hauv kev sib tsoo, Piv txwv, siv hom, qhuav los ntub dej, thiab tus tsis tsim sprayer.
Nyhav ib pob zeb mas nws txawv nrog rau lub particle loj (lub ntees yog sib luj kev khees), ces nws yuav ua rau kom nws xam tus nqi ntau lawm peev xwm crushers thiab Mills los ntawm tagnrho mus kho tau thiab yuav tsum tau kawm ntawv disintegration.
