Summary: Basalt waa walaxda ugu fiican ee dhagaxa ah ee loo isticmaalo dayactirka wadooyinka, tareenada, iyo xariiqa garoonka diyaaradaha. Waxay leedahay adkaysi u adkeysata jarista, nuugista biyaha oo hooseysa, koronto gudbinta oo hooseysa...
Basal waa qalabka ugu fiican ee dhagaxa loo isticmaalo dayactirka waddooyinka, tareenada, iyo duraasha garoonka diyaaradaha. Waxay muujisaa iska caabin dufan, nuugista biyaha oo hooseysa, korantada oo hooseysa, adkeysiga cadaadiska oo sareysa, qiimaha jabitaanka oo hooseeya, iska caabin daxalka ah oo heer sare ah, iyo adkeysi xooggan oo asphalt ah. Waxa si caalami ah loogu aqoonsan yahay in uu yahay agab ku habboon dhismaha tareenada iyo wadooyinka.
Marka laga hadlayo shiidi iyo sameynta ciidda dhagaxyada adag sida basalt iyo granite, dad badan waxay ka welwelsan yihiin in qaybaha dheeraadka ah si daran u duugo, beddelka ayaa ah mid aad u badan, wax-soo-saarku ku guul darreysto shuruudaha naqshadeynta, waxqabadka ayaa ah mid hooseeya, ciidda dhameystiran ayaa leh qaab grain oo liita. Runtii, samaynta ciidda ka timid dhagaxyada adag sida basalt waa kuwo aad u adkaada!
Dhibaatooyinka burburinta iyo qalabka basalt-ka
1. Basalt waxa uu leeyahay adkeysi sare oo cadaadis ah, adkaysi wanaagsan oo dhagax ah, adkeysi sare, xooga sare ee xoqitaanka iyo dhibaatooyin aad u weyn oo burburin ah, taas oo adag inay burburiyaan, taasina waxay adag tahay.
2. Ka dib habka jebinta basalt-ka, alaab-yar amaba waxsoosaarka ugu dambeysa waxay leeyihiin qaab dabeecad adag oo dhib badan in la xakameeyo waxyaabaha is daba joogta ah ee flakes-ka ee ku jirta waxyaabaha badan ee dhamaadka ah si loo buuxiyo shuruudaha qeexitaanka.
3. Ka dib habka samaynta ciidda ee basalt-ka oo ay sameyso shiilaha saameynta quudinta toosan, waxyaabaha ku jira dhagxaanta yaryar iyo bur burka waaweyn ee warqadda ka yar 5mm ayaa ah kuwo aad u sarreeya, halka qaybaha yaryar aysan ku filneyn. Sidoo kale, ciiddu waxay leedahay modulus fineness oo sarreeya iyo waxyaabaha burburka dhagaxa ee hooseeya. Haddii macaamiishu qaataan warehouse gidaarka ah si ay u farsameeyaan basalt-ka si loo sameeyo ciid, wax-soo-saarka hal unug waa mid hooseeya, halka isticmaalka biyo, isticmaalka birta iyo korantada oo dhamaantood ay sarreeyaan.
Tallaabooyinka teknoolojiyada ee nidaamka burburinta basalt
During the preparation period of a hydropower station, the sand and gravel processing system encountered the above problems. The raw materials are dense massive basalt and amygdaloidal basalt, with dry compressive strength ranging from 139.3–185.7 MPa and 163.3–172.9 MPa respectively. The total amount of concrete to be processed by the system is about 1.2 million m³, and the production capacity of the system is 154,000 T/month. Among them, the processing capacity of raw material is 560t/h, the production capacity of finished aggregate is 396t/h, and the production capacity of finished sand is 140t/h.
Doorashada qalabka
Iyadoo la tixgelinayo sifaha basalt-ka, ayaa la go'aamiyey in la qaato habka "afar-waji burburin, burburiyaha duleelka toosan iyo mashiinka furdaaminta silsiladda iyo farsamada samaynta ciidda (habka caadiga ah ee samaynta ciidda)". Qaab-dhismeedyada ugu muhiimsan ee shaybaarka waxaa ka mid ah: shaybaarka burburinta ceeqa, shaybaarka burburinta dhexdhexaadka ah, shaybaarka shaandhaynta, shaybaarka samaynta ciidda, shaybaarka kormeerka iyo shaandheynta dib, dhulka kaydinta agabka ceeqa iyo faaqida ah, iwm. Intaas waxaa sii dheer, heerka culeyska qalabka waa in la ilaaliyaa mid hooseeya inta lagu jiro doorashada, iyadoo la heysto qalab wax soo saar ku filan.
2. Xakamaynta qaabka dhinacyada isku-darka dhammaadka
Iyada oo la tixgalinayo dhibaatooyinka tayada dhinacyada oo liidata iyo qaddar badan oo jajab yar iyo kuwa dhexdhexaad ah oo qaab ulaha ah isku-darka dhammaadka ka dib markii la warshadeeyo basalt, tayada isku-darka waaweyn ee dhammaadka waxaa lagu xakamayn karaa iyada oo loo marayo tallaabooyinka soo socda:
Dhinac: xakamaynta heerka burburinta dhexdhexaadka iyo kuwa yaryar, quudin joogto ah, fulinta quudinta dhammaystiran, burburin lakabaysan iyo tallaabooyin kale si loo xakameeyo tayada dhinacyada.
Dhinaca kale: Iyadoo la tixgelinayo sifooyinka ku jira qaybaha waaweyn ee u eg qanjidhada dusha sare leh ee ka dhasha burburinta basaltka, waxaa la adeegsadaa mashiinka qaabeynta. Waa shirka baarista ugu horeeya ee ka dambeeya burburinta dhexdhexaad ilaa jilicsan ma soo saaro qaybo dhammaystiran oo yaryar, balse kaliya qaybo waaweyn iyo kuwa dhex dhexaad ah. Qeybo waxaa loo rarayaa shirka burburinta aadka u dhuuban (oo leh 3 qalab oo burburiya vertical shaft impact crushers oo leh hawlaha qaabeynta). Kadib markii la qaabeeyo ee shirka labaad ee baarista, waxaa la soo saaraa qaybaha yaryar iyo kuwa ka yar 5 mm.
3. Xakameynta heerka dhismaha ciidda, heerka kala duwanaanta fineness iyo qaddarka budada dhagaxa
Iyada oo laga duulayo astaamaha heerka hoose ee sameynta ciidda, tirada dhibcooyinka sare ee ciidda dhammaystiran iyo tirada hoose ee budada dhagaxa ee ciidda basalt, tallaabooyinka soo socda ayaa loo adeegsadaa si loo hagaajiyo:
Marka hore, waxaad hagaajin kartaa xawaaraha rotor ee jajabinta taagan ee vertical, hagaajiso xawaaraha toosan ee isku-darka ee godka jajabinta, waxaad hagaajin kartaa heerka sameynta ciidda iyo tirada budada dhagaxa ee ciidda la soo saaray, isla markaana waxaad dhimi kartaa tirada dhibcooyinka ciidda.<
Marka labaad, hagaaji heerka quudinta burushka saamaynta geeska toosan, taasoo hagaajin karto saameynta sameynta ciid aad u fiican.
Saddexaad, tirada qaybaha dhagaxyada ee isku dhafka ka yar 5mm ee nidaamku soo saaro kadib burburinta weyn iyo burburinta dhexe iyo midda yar waa sare. Habkaani wuxuu ka dhigayaa qaybtaan isku dhafka inayaan ahayn alaabooyin dhamaystiran, sidaas darteed dhammaan isku dhafka ka yar 5mm kadib burburinta dhexe iyo midda yar waxaa loogu dhaafiyaa burburiye dhuumaale toosan si loo qaab-bedelayo, si loo xakameeyo tayada ciidda dhammaystiran.
Inkogorta afaraad, makiinada dhulka ee toosan ayaa farsameysa isku dhafka laga soo saaro qolka shaandheynta labaad. Weedhaha hoose ee ka yar 5 mm waxay galayaan mishiinka birta ah ee rididda si dib loogu qaybo si loo habeeyo heerka siman ee cufnaanta iyo nashasha qabriga dhammaatay.
Shanaad, marka la isticmaalayo buriinka tooska ah ee toosan si loo soo saaro ciid cusub, qoyaan yar oo ku jira dhammaan qashinka la farsameeyay ayaa ah mid wanaagsan oo kor u qaada saameynta samaynta ciidda. Marka loo eego astaantan, habka qallalan oo dhan ayaa la adeegsadaa si loo horumariyo saameynta samaynta ciidda ee mashiinka samaynta ciidda.
4, Qaddarka ciidda dhagaxa ee ciidda dhammaystirtay
Nidaamka waxa uu soo saaraa ciid caadi ah oo loogu talagalay siman iyo ciid loogu talagalay RCC. Farqiga ugu weyn ee u dhaxeeya labada nooc ee ciid waa kala duwanaanshaha qaddarka ciidda dhagaxa, kaasoo ah 6-18% ee midkii hore iyo 12-18% ee tan labaad. Inta lagu jiro habka,
Kuwaliba hore, wax badeeco dhammaatay ma la daayay ka dib jarista dhexe iyo mid khafiifa. Dhamaan alaabada la jarey waxay marayaan shaandhayn labaad iyo kala soocid ka hor inta aan lagu shubin burburiyeyaasha toomasada toosan ee jiiska. Qaadista 3–5 mm ayaa la kala saaraa lana geeyaa mashiinka birta ah ee fallaaraha si loo sii burburiyo. Habka waxa uu qaataa habka wax-soo-saarka oo dhan qalalan. Si si sax ah loo xakameeyo macdanta dhagxaanta iyo heerka faquka ee ciidda shubka ee tayada leh, waxaa la adeegsanayaa burburiyeyaasha toomasada toosan iyo tiknoolajiyadda habka qallalan.
Marka labaad, burburiyaha dhinaca toosan ee tooska ah iyo qolofka birta ah ayaa loo isticmaalaa inay sameeyaan ciidda loogu talagalay RCC. Isla mar ahaantaana, budada dhagaxa ayaa laga soo ceshadaa ciidda wanaagsan ee lumay inta lagu jiro dhaqidda ciidda. Dhammaan budada dhagaxa ee uu soo saaro qalabka soo kabashada ayaa lagu dhex daraa ciidda RCC si loo kordhiyo waxyaabaha budada dhagaxa ah ee ku jirta.
