B Apron Feeder Hauv Coal Handling Cogyog peb lub Hoobkas raws li qhov xav tau ntawm cov neeg siv, 400C thaiv thiab cov khoom siv granular, raws li kev xa khoom tas mus li tom qab kev tshawb fawb kev lag luam, siv rau cov ntaub ntawv hauv tsev thiab txawv teb chaws, cov khoom siv, yog tsim rau me me thiab nruab nrab -sized cement cog limestone, ib yam khoom, nws yog tsim rau raws li qib los yog dumping Qib crushing qhov muag khoom kuj yuav siv tau nyob rau hauv mines thiab lwm yam kev ua hauj lwm zoo sib xws (nruab nrab ntawm cov kab ntau tshaj li 2.)
Rau lub crusher, conveyor los yog lwm yam machinery ua hauj lwm yog nruam nrog 1 yam ntxwv daim ntawv thiab cov yam ntxwv
Allotment los yog transshipment ntawm ntau yam tso cai thauj khoom ceev tsis ntau dua
B hom Apron Feeder Hauv Coal Handling Cog muaj cov cuab yeej saw hlau, lub taub hau lub log, 2400kg / m, thaiv qhov hnyav tsis tshaj 50okg, qhov kub tsis siab tshaj lub log log tensioning, tsav tsheb thiab lwm yam khoom.
Lub cev ntawm daim duab 1 pem teb loading
Cov khoom siv saw hlau pom nyob rau hauv daim duab 1 yog cov load- bearing tus tswv cuab ntawm feeder tuab steel phaj stamping rau hauv ib tug wavy zoo, thiaj li hais tias nws muaj txaus lub zog, thiab traction qhov chaw, raws li ib tug bearing tus tswv cuab ntawm lub tank lub cev ncaj lub tsev thiab cov khoom thiab nruj, ob sab ntawm lub hauv qab phaj vuam daim tiab, los tiv thaiv cov khoom me me sib cuag, nyob rau hauv thiaj li yuav tiv taus cov khoom loj ntawm lub phaj, hauv qab ntawm cov khoom loj, los tiv thaiv cov khoom loj ntawm cov phaj. traction tus tswv cuab ntawm cov saw yog sab laug thiab sab xis ob Cement thiab txiv qaub
Cov txheej txheem ntawm cov menyuam yaus yooj yim, nws muaj kev cuam tshuam, kev khiav haujlwm zoo, kev ua haujlwm tuaj yeem ntsia tau rau hauv nruab nrab ntawm cov saw log yog ob qho tib si lub zog sib kis thiab cov neeg taug kev, cov qauv yooj yim, compact, sab laug thiab sab xis saw txuas nrog lub cev ntsia liaj qhov rooj, tsis txhob siv cov feem ntau siv los ntawm cov ncej kom lub teeb yuag, txuag cov khoom, vim hais tias sab laug, txoj cai traction saw tsis txuas los ntawm cov ncej, ob lub sprocket tails
Lub dynamic bearing yog tsau rau ntawm ncej, lub zog traction ntawm ib tug saw tsuas yog 1/2 ntawm tag nrho cov traction quab yuam, thiab lub unbalance coefficient ntawm 75% ~ 80% yuav tsum tau txiav txim siab nyob rau hauv daim ntawv ntawm ib tug saw gravity quab yuam txuas nrog lub ncej. Qhov tseeb traction quab yuam ntawm B Apron Feeder Hauv Coal Handling Cog yog 20% ~ 25% siab dua li ntawm daim ntawv txuas nrog lub ncej. Tsis tas li ntawd, sab laug thiab sab xis strips muab tso rau sab nraud ntawm lub cev kom yooj yim rau kev saib xyuas thiab kev saib xyuas ntawm cov saw hlau ruaj ntseg log raw.

C-1.0 rau L<25m
Lub taub hau yog muab nrog lub taub hau txuas nrog lub crusher, Thaum 25m<σl<60m>
Npog, nws txoj haujlwm yog los pab txhawb cov concentration ntawm cov khoom siv rau hauv crusher, tiv thaiv
Raws li formula (1), lwm yam kev mob sib npaug me me thiab nruab nrab pob zeb ya tawm ntawm lub dav hlau thaum lub sij hawm crushing txheej txheem. Hauv qab no, dynamic load S / yog inversely proportional rau lub square ntawm lub phaj nyeem x.
Lub taub hau txiv hmab txiv ntoo, nruab nrab thav duab ntawm Apron Feeder Nyob rau hauv Coal Handling Cog, Tail txiv hmab txiv ntoo, lub sab sauv thiab sab rail ua tus zoo li qub nrog txo tus naj npawb ntawm cov hniav, lub dynamic load yuav nce sharply. Nyob rau tib lub sijhawm, tus ncej plays lub luag haujlwm ntawm kev txhawb nqa thiab hloov pauv hauv lub feeder.
Lub dynamic load nyob rau hauv lem yog proportional rau lub square ntawm ceev t ntawm cov saw phaj.
Lub cushion yog ntsia rau hauv qab phaj ntawm qhov chaw blanking, yog li yog tias qhov kev khiav ceev yog siab, yuav tsum siv cov hniav ntau dua.
Ib qho cuab yeej rau Apron Feeder Hauv Coal Handling Cog los txhawb qhov cuam tshuam ntawm cov khoom poob thiab tiv thaiv qhov deformation ntawm cov phaj hauv qab, cov hniav me me, yuav tsum dais cov kev xaiv ntawm kev khiav qis, thawb cov hniav ntawm cov hlau thiab ntoo sib xyaw qauv, tsis tsuas yog ua kom cov kev ua tau zoo, tab sis kuj txo tus naj npawb ntau x=5 ~ 13, thaum lub conveyor khiav ceev yog siab, yuav tsum yooj yim txheej txheem.
Siv x=8~12,B Apron Feeder Hauv Coal Handling Cog khiav ceev dua

Tsawg, yog li ntawd, tus naj npawb ntawm cov hniav sprocket x=8.
(1) Chain phaj dav B series yog 800mm,
(3) qhov piv ntawm lub suab tseem ceeb muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub feeder
1000mm, 1250mm peb specifications
Thiab cov txiaj ntsig kev lag luam, (1) cov qauv r rau hauv qhov tseeb: (2) tus naj npawb ntawm cov hniav sprocket yog tsav los ntawm cov nyhuv ntau yam nyuj S= pr/(60g) (qL, + C.9.L, + 9-H) (2) dynamic load tseem ceeb yam, rau cov phaj feeder, saw
Raws li kev sib npaug (2), lwm yam kev sib npaug.
Qhov siab tshaj plaws load S ntawm lub sawb tuaj yeem xam raws li cov qauv hauv qab no:
Down: Dynamic load yog proportional to the traction key pitch, if the single move
S3/g (gl, +Ca+9H)
Nyob rau hauv cov nqe lus ntawm load, lub suab yuav tsum tsis txhob loj heev: tab sis los ntawm cov nyiaj txiag pab
Yog sib npaug rau 20. Saib, raws li kev tso cai, qhov kev ncua deb yuav tsum loj npaum li qhov ua tau kom lub phaj s=60/(rp g)(qL, + C Lub cev hnyav ib meter ntawm qhov khiav ntawm lub feeder yog txo los ntawm lub assembler + 4-H)
1) Kev txo qis, kev siv hluav taws xob tsawg hauv kev ua haujlwm txhua hnub, xws li B=800 pub
Qhov twg Lub feeder, yog hloov nws lub suab p-315 mus rau 200, ib 'meter' 4... Ib tus nqi siab tshaj acceleration ntawm lub ntiajteb txawj nqus, m/s Tus kheej qhov hnyav yuav nce los ntawm 21%, thiab kev tsim khoom thiab kev sib dhos ua haujlwm yuav nce los ntawm 1.8 8 ib qho gravitational acceleration, 9.8m / a,
Yog li ntawd, kev sib hloov yuav tsum tau txiav txim siab thaum txiav txim siab lub zog txuag ntawm cov saw hlau traction
va kev noj qab haus huv phaj khiav ceev, w= zpn/60, m/si Yam ntxwv, tab sis kuj xav txog cov txiaj ntsig kev lag luam, B Apron Feeder Hauv Coal Handling Cog.
