Chigayo chemarasha chikamu chakakosha chesystem yekupwanya uye chishandiso chakakosha chemagetsi mufekitori yemagetsi. Basa rayo guru nderekupwanya nekupwanya marasha kuita marasha akapwanywa kuti ape michina yebhoyira, magadzirirwo ayo achaita zvakananga kuchengetedzeka uye hupfumi hweyuniti. Nekuti kuchinjika kwezvigayo zvemarasha zvakasiyana kune mhando dzakasiyana dzemarasha kwakasiyana zvikuru, pamwe chete nemamiriro chaiwo ekugoverwa kusina kuenzana kwezvigadzirwa zvemarasha muChina, mhando yezvigadzirwa zvemarasha ichakanganisa zvakananga hupfumi hwesystem yekupwanya. Saka, kusarudzwa kwemidziyo yekupwanya marasha kunofanira kusarudzwa sei?Michina yeHCMSemugadziri wezvigayo zvemarasha, achatanga hwaro hwekusarudza zvigayo zvemarasha. Kune mhando dzakawanda dzezvigayo zvemarasha, zvichienderana nekumhanya kwezvikamu zvinoshanda zvekugaya zvechikamu chekusarudza michina yemagetsi zvinogona kukamurwa kuita mhando nhatu, dzinoti: chigayo chemarasha chine kumhanya kushoma, chigayo chemarasha chine kumhanya kwepakati uye chigayo chemarasha chine kumhanya kukuru. Zvinotevera zvichatanga kusarudzwa kwemidziyo mitatu iyi yekugaya marasha zvakateerana.
Sarudzo yemidziyo yemuchina wemarasha 1: muchina wemarasha unomhanya zvishoma
Chimiro chinowanzo shandiswa ne "low speed coal mill" ndicho "ball mill". Musimboti wekushanda ndewekuti: mota ine simba guru inopinda mu "gearbox" kuti ifambise "round" iyi inorema, "steel ball" iri mu "simple" inotenderedzwa kusvika pakakwirira uye yobva yadonha, kuburikidza nekukanganiswa kwe "steel ball" pa "coal" uye pakati pe "steel ball", pakati pe "steel ball" ne "guard plate", "coal" inogayiwa. "Coal" isina kukodzera inoparadzaniswa kana ichiyerera nepakati pe "coarse powder separator" kumashure kwe "ball mill", uye yozotumirwa ku "round plate" kubva pa "return powder tube" kuti igaye zvakare. Kuwedzera pakutakura "coal powder", "hot air" inoitawo basa rekuomesa "coal". Saka, "hot air" inonziwo "desiccant" mu "powder system". Chigadzirwa ichi chine hunhu hwe "long-operating" hunogara kwenguva refu, "easy retaining", "stable output" uye "fineness", "saving spare coal machine", "wide range of grinding coal" nezvimwewo. Inonyanya kushandiswa pa "hardness ratio" nepakati, kunyanya pa "coal" ine "volativity" yakawanda uye "strong abrasive property". Zvisinei, chigayo ichi chebhora chinomhanya zvishoma chakakura, chinoshandisa simbi yakawanda, chinotora nzvimbo yakawanda, uye chine mari yakawanda yekutanga. Saka chigayo ichi chakakodzera kushandiswa zvizere.
Midziyo yemagetsi emarasha mhando yechipiri:chigayo chemarasha chinomhanya zviri pakati nepakati
Chigayo chemarasha chinomhanya pakati nepakati chinozivikanwawo sechigayo chemarasha chakamira, icho chinoratidzwa nezvikamu zvekukuya zvinoumbwa nemapoka maviri ekufamba kwemuviri wekukuya. Marasha anodzvanywa uye anokuyiwa pakati penzvimbo mbiri dzekukuya uye anopwanywa. Panguva imwe chete, mhepo inopisa inopinda nemuchigayo inoomesa marasha uye inotumira marasha akakuyiwa kumuchina wekuparadzanisa uri pamusoro penzvimbo yemuchina. Mushure mekupatsanurwa, marasha akakuyiwa ane saizi yakati yezvidimbu anotorwa kubva muchigayo nemhepo inoyerera, uye marasha akakuyiwa anodzoserwa kunzvimbo yekukuya kuti agayiwezve. Chigayo chemarasha chinomhanya pakati nepakati chine zvakanakira zvemidziyo midiki, nzvimbo diki, kuchengetedza simba (inenge 50% ~ 75% yemuchina webhora), ruzha rushoma, chiedza uye kudzora mashandiro anonzwa. Asi hachina kukodzera kukuya marasha akaomarara.
Sarudzo yemidziyo yechigayo chemarasha 3: chigayo chemarasha chinomhanya zvikuru
Kumhanya kwemuchina wemarasha unomhanya zvikuru i500~ 1500 r/min, iyo inonyanya kuumbwa nerotor inomhanyisa uye goko rekukuya. Kukuya kwefeni kwakajairika uye kukuya nehammer nezvimwewo. Mumuchina, marasha anopwanywa nekusangana pakati pekukanganisa kwekukurumidza negoko rekukuya uye kusangana pakati pemarasha. Rudzi urwu rwemuchina wemarasha uye muchina wekuparadzanisa marasha wakakuyiwa zvinoumba zvese, chimiro chacho chiri nyore, chakamanikana, mari yekutanga yakaderera, inonyanya kukodzera kukuya lignite ine hunyoro hwakawanda uye ine volatible yakawanda, iri nyore kukuya marasha e-bituminous. Zvisinei, nekuti plate yekukanganisa inopwanyika zvakananga uye inopfekwa nemhepo inoyerera, hupenyu hwayo hwebasa hunowanzoita 1000h chete pakukuya lignite, kutsiva kakawanda, uye huwandu hwemvura hwemarasha epasi hahufanirwe kunge hwakanyanya kukwira, iyo inowanzo shandiswa kumaboilers anoputika zvakananga mumafekitori emagetsi, uye haifanirwe kushandiswa kumaworkshops ekuisa blast furnace.
Mhando nhatu dzemidziyo yekukuya marasha dziri pamusoro apa dzine zvakanakira nezvadzisina, pakusarudza michina yekukuya marasha, zvakakosha kufunga nezvesarudzo yese yesystem yekukuya marasha. Sisitimu yeupfu inogona kukamurwa kuita zvikamu zviviri: mhando yekuputira zvakananga uye mhando yekuchengetera pakati (inonzi rudzi rwekuchengetera). Musystem yekukuya marasha zvakananga, marasha anokuyiwa kuita marasha akakuyiwa nechombo chemarasha obva afuridzirwa zvakananga muchoto kuti apiswe. Musystem yekukuya marasha, marasha akakuyiwa anotanga kuchengetwa mubhini remarasha rakakuyiwa, uye zvinoenderana nezvinodiwa nemutoro webhoyira, marasha akakuyiwa anotumirwa kubva mubhini remarasha rakakuyiwa kuenda kuchoto kuti apiswe nechombo chemarasha. Masisitimu akasiyana ekukuya akakodzerawo mhando dzakasiyana dzemidziyo yekukuya marasha nemarasha. Zvichienderana nesystem yekukuya, takapfupikisa hwaro hunotevera hwekusarudza chigayo chemarasha:
(1) Chigayo chesimbi chesimbi chiri pakati pebhini rekuchengetera zvinhu chinopisa: chinogona kushandiswa pakurwisa anthracite (Vsr<9%) uye kupera simba pamusoro pemarasha.
(2) Sisitimu yekutakura upfu hwegasi inoburitsa upfu yemhando yeBall mill: inonyanya kushandiswa pamarasha ane marasha akasimba uye ane ngura yepakati (Var-19% ~ 27%).
(3) Sisitimu yekuputira yakananga yesimbi ine mativi maviri inobuda nesimbi 22-241: yemarasha ekubikisa ane mwero wepamusoro (Vs.7-27% ~ 40%) bituminous.
(4) Sisitimu yekuputira yakananga yemuchina wemarasha unomhanya nepakati: yakakodzera kukuya marasha ebhituminous ane huwandu hwakawanda hwemhepo inoputika (Vanr-27% ~ 40%), huwandu hwakawanda hwemvura (hunyoro hwekunze Mp≤15%) uye kupera kwakasimba, pamwe nekurasikirwa kwenhema kwemarasha pasi pesimba rakasimba, mashandiro ekupisa marasha anogona kutsva, uye kupfava kwemarasha akakuyiwa kunosangana nezvinodiwa zvemuchina wemarasha.
(5) Sisitimu yekuputira feni zvakananga: yakakodzera bhaira remafuru e lignite ane simba reKe≤3.5 ne50 MW uye pasi pe bituminous coal unit.
Mukusarudza michina yekugaya marasha, inofanira kutariswa zvichienderana nehunhu hwekutsva, hunhu hwekusakara nekuputika kwemarara, hunhu hwekupwanya kwemarara uye zvinodiwa zvekupwanya marasha, pamwe chete nechimiro chechoto uye chimiro cheburner chebhoyira, uye kufunga nezvekudyara, huwandu hwekuchengetedza nekushanda kwegwenya remagetsi nemidziyo inotsigira, kuwanikwa kwezvikamu, kwakabva marasha nemarara mumarara nezvimwe zvinhu. Kuti tiwane kuwirirana kwakanaka pakati pesystem yekupwanya, mudziyo wekupisa nechoto chebhoyira, kuve nechokwadi chekushanda kwakachengeteka uye kwehupfumi kweyuniti. HCM Machinery inyanzvi mukugadzira vagadziri vemichina yemagetsi inomhanyisa pakati nepakati, tinogadzira HLM series yemichina yemagetsi inomhanyisa pakati nepakati ine hunhu hunotevera:
(1) Kushandiswa kweroller nedhisiki hombe, kuramba kuchinjika kudiki, mamiriro ekupinda kwemarasha asina kubikwa akanaka, nokudaro zvichivandudza kugona kwekugadzira, kuderedza kushandiswa kwesimba.
(2) mashandiro ekuderedza simba zvakanaka, zvakachengeteka uye zvakavimbika; Ruzha rushoma uye kudedera; Kushanda kwekuvhara simba kwakanaka kuitira kuti upfu hwemarasha husapinde muzvikamu zvese zvemakanika zvinotenderera.
(3) Yakakodzera kukuya marasha akaomarara, simba rekukuya rakafanana, kushanda zvakanaka kwekukuya. Inoshanda zvakagadzikana uye yakavimbika.
(4) Kukuya kweMPS hakupo muzvikamu zvisingashande zvakanaka zvekukweshana, uye simbi yacho haishande zvakanaka. Kana uine dambudziko rekusarudza michina yemagetsi emarasha, tinokugamuchirai kuti mutaure nesu.Michina yeHCM for the basis of coal mill selection, contact information:hcmkt@hcmilling.com
