Mugihe igihugu giha agaciro ibidukikije, nkubwoko bwimyanda ikomeye, uburyo bwo gukoresha ibyuma byahindutse ingingo yingenzi.Iyi ngingo itangiza igisubizo cyuzuye cya tekiniki yo gutunganya ibyuma bya tekinoroji.Ikoranabuhanga ryumye rigomba kwemeza ko ibyuma bisubirana neza kuruhande rumwe no gukoresha neza ibisigazwa byimyanda kurundi ruhande.Intambwe ikurikira yo gutunganya ibyuma byerekana ibicuruzwa: Kumenagura guhitamo;gutandukanya magnetiki ninshingano yibikoresho bishya bigizwe na moteri imwe-yumuvuduko ukabije wimashini mugukoresha byimazeyo ibyuma;gukoresha ibikoresho bishya birashobora kugabanya cyane ikiguzi cyo kumenagura ibyuma, bityo bikabyara inyungu nyinshi mugukoresha ibyuma.Gutezimbere ikoreshwa ryuzuye ryicyuma byashizeho ibishoboka.Gutezimbere iki gitekerezo cyuzuye mu nganda bisaba imbaraga zihuriweho n’amasosiyete akora ibyuma, impuguke n’intiti zitunganya amabuye y'agaciro, ishyirwa mu bikorwa muri rusange, hamwe n’ishami rishinzwe kwamamaza no kuzamura.
Ubwubatsi bukoresha ibyuma
1) Icyuma gikoreshwa mubyuma bya sima nibindi bivanze.Icyuma kirimo ibyuma byubaka nka silikatike ya tricalcium (C3S), silikatike ya dicalcium (C2S) hamwe na fer aluminate hamwe na hydraulic cimenting, ibyo bikaba bihuye nibiranga sima.Kubwibyo, irashobora gukoreshwa nkibikoresho fatizo hamwe na sima ivanze kugirango ikore sima idafite clinker, sima nkeya.Isima ya sima ya sima ifite ibintu byiza cyane nko kwihanganira kwambara, imbaraga zidasanzwe, kurwanya ruswa no kurwanya ubukonje.
2) Icyuma cyicyuma gisimbuza amabuye yajanjaguwe hamwe hamwe.Amabuye yamenetse yamashanyarazi afite ibyiza byimbaraga nyinshi, hejuru yubuso, kwihanganira kwambara no kuramba, ingano nini, ituze ryiza, hamwe no guhuza hamwe na asfalt.Ugereranije namabuye asanzwe ashenjaguwe, irwanya kandi Ibiranga ubushyuhe buke, bityo irashobora gukoreshwa cyane mumihanda yinyuma.Icyuma cyuma, nka ballast ya gari ya moshi, gifite ibiranga kutabangamira ibikorwa byitumanaho rya sisitemu ya gari ya moshi hamwe nu mashanyarazi meza.Kuberako icyuma gifata amazi meza kandi kigatemba, ibice bya sima birimo birashobora gutuma bikomera mo ibice binini.Icyuma cy'icyuma nacyo gikwiriye kubakwa mumihanda mu bishanga no ku nkombe.
Kugeza ubu, uburyo bukoreshwa cyane mu byuma byo mu rugo ni ugusenya ibyuma kugeza kuri -5mm kugirango bisimbuze umusenyi winzuzi nkibikoresho byubaka, cyangwa gusya umupira wo gusya icyuma cyajanjaguwe mo ifu nziza kugirango ukoreshwe nka sima.Shandong Huate Magnetoelectric Technology Co., Ltd. yakoze kandi ubushakashatsi bwimbitse ku mikoreshereze yuzuye y’icyuma, mu buryo bushya bwo gukoresha imashini imwe y’umuvuduko ukabije w’imashini kugira ngo isya neza ibyuma, byongereye ikoranabuhanga mu gutunganya ibyuma, kandi yageze ku nyungu nziza zubukungu.Byakoreshejwe neza muri Pangang Mining hamwe ninganda runaka yicyuma muri Lianyungang.
Uburyo bwa gakondo bwo gukora ibyuma ni ibi bikurikira:
1) Ibice binini byajanjaguwe hamwe na jasheri kugeza kuri -50, kandi icyuma cya magneti gitandukanijwe na pulley.
2) Shiraho ubunini bwo gutandukanya ibyuma kuri +45 mm.Mm 0-45 isigaye ikoreshwa muburyo bwo kubaka umuhanda no kuzuza ibikoresho.Kugirango wongere agaciro kayo, icyuma gishobora kugabanywamo 0-4, 4-8 nandi manota atandukanye.Ikoranabuhanga risaba igishoro gito nigiciro gito cyo gukora.Nyamara, ibice birenga 50% byibyuma biri muri slag byibanda kumbaraga -10 mm, ubwo rero tekinoloji izatera ibyuma byinshi gutakaza, ariko ibyuma biremereye biziyongera.
Kubwibyo rero, gusya neza bitose byakoreshejwe cyane cyane kumashanyarazi yakozwe mugukora ibyuma birebire cyane birimo Cr, Ni, Mo, nibindi. ).Kubera ko icyuma gifite guhindagurika kitoroshye gusya, gutandukanya ibyuma nicyuma birashobora kugerwaho no gushungura cyangwa gutondeka.Ubwiza bwigice cyamabuye ya slag mubusanzwe buri hejuru ya 95% no munsi ya 0.2mm.Igipimo cyo kugarura ibyuma muriki gikorwa kirenga 95%, naho umusaruro wibyuma byibanze ni 90 kugeza 92%.Urebye gutandukanya ibyuma na slag, iyi nzira irashobora kuvugwa ko aribwo buryo bwiza.
Ingaruka nyamukuru yiyi nzira nuko icyuma gitandukanijwe nicyuma cyiza cyane.Kuberako inzira ari inzira itose, biragoye kuyikoresha mubwubatsi.Kubwibyo, ibyinshi mubikoresho byicyuma bisigaye nyuma yo gutoranya ibyuma byajugunywe, kandi ibi akenshi biterwa nigiciro kinini cyo gukama neza kandi byemewe n'amategeko kwisi yose.Igiciro icyo aricyo cyose gisaba agaciro bisaba ubundi buryo bwo kuvura ibishishwa bitose (gukama, kubyimba, nibindi).
Guhitamo bigomba gukorwa hagati yicyuma cyo kugarura ibyuma cyangwa kuboneka kwa slag isigaye.Mubisanzwe, guhitamo biterwa nagaciro kicyuma cyagaruwe.
Inzira zisanzwe muriki cyiciro nizi zikurikira:
Ibice binini byajanjaguwe hamwe na jaseri kugeza kuri -50, kandi icyuma cya magneti gitandukanijwe na pulley.
-Icyuma cya 50 cyashenywe na crusher ya nyundo cyangwa igikonjo, igikonjo cyogusunika, gushungura binyuze mumashanyarazi menshi, -20-10 grit progaramu irashobora gukoreshwa nka kaburimbo, -10-1 grit irashobora gukoreshwa nkumusenyi mwiza.
Imbonerahamwe I.
Isesengura ryubunini bwa 50mm kugaburira inyundo
-Icyuma cy'icyuma cy'ibinyampeke gishyirwa mu ruganda rwumutse rwumye -200 meshi nziza, hanyuma amashanyarazi akoresha amashanyarazi akoresha amashanyarazi kugirango akureho icyuma nka sima.
