Dhayi ndiyo chinhu chikuru mugayo repellet. Uye ndiyo kiyi yekugadzira mapellets ekudya. Zvichienderana nehuwandu husina kukwana, mutengo wekurasikirwa kwepellet mill unodarika 25% yemari yekugadzirisa yese yekugadzira. Pakuwedzera kwemari yemubhadharo wega wega, kukwikwidzana kwako pamusika kunoderera ne0.25%. Saka zvinodiwa zvepellet mill zvakakosha zvikuru.
Shanghai Zhengyi (CPSHZY) inyanzvichigayo chepellet chekudyisa chikafuMutengesi muChina. Tinopa ring die pellet mill, flat die pellet mill uyezvikamu zvepellet chigayo, zvakaita se flat die, ring die, pellet mill roller, nezvimwe zvikamu zvemuchina wepellet.
1.Zvinhu zvekufa zvepellet mill
Chigayo chepellet chinowanzogadzirwa nesimbi yekabhoni, simbi yesimbi yakagadzirwa nesimbi isina ngura kana simbi isina ngura kuburikidza nekugadzira, kugadzira machining, kuboora maburi, uye nzira dzekupisa. Mushandisi anogona kusarudza zvichienderana nekuora kwechinhu chisina ngura. Chigayo chepellet chinofanirwa kugadzirwa nesimbi yakagadzirwa nesimbi isina ngura kana ring mold yesimbi isina ngura.
Simbi yesimbi yakagadzirwa nekabhoni, senge simbi ye45, kuoma kwayo kurapwa nekupisa kunowanzova 45-50 HRC, chinhu chine mhete yemhando yepasi, kuramba kwayo kupfeka uye kuramba kwayo ngura kwakashata, ikozvino kwabviswa zvachose.
Simbi yesimbi yakagadzirwa nealloy, yakaita se40Cr, 35CrMo, nezvimwewo, ine kuomarara kwekupisa kuri pamusoro pe50HRC uye ine hunhu hwakanaka hwemakanika. Dhayi yakagadzirwa nezvinhu izvi ine simba rakawanda uye inodzivirira kupera, asi dambudziko nderekuti inodzivirira ngura haina kunaka, kunyanya pakudya hove.
Mutengo we ring dies, wakagadzirwa nezvinhu, marigold pellets, matanda chips, straw pellets, nezvimwewo, wakakwira zvikuru kupfuura simbi isina ngura. 20CrMnTi ne20MnCr5 ese ari maviri isimbi dze alloy dzine carburizing low-carburizing, ese ari maviri akafanana, kunze kwekuti yekutanga isimbi yeChina uye yekupedzisira isimbi yeGerman. Sezvo Ti, chinhu chemakemikari, chisingawanikwe kunze kwenyika, 20CrMnTi kana 20CrMnn kubva kuChina inoshandiswa panzvimbo ye20MnCr5 kubva kuGermany, saka haiwire mukati mesimbi ye alloy structural. Zvisinei, simbi iyi yakaoma inogumira ne carburizing process kusvika pakadzika kwe 1.2 mm, iyo iriwo mukana wemutengo wakaderera wesimbi iyi.
Zvinhu zvesimbi isina ngura zvinosanganisira simbi isina ngura yeGerman X46Cr13, simbi isina ngura yeChina 4Cr13, nezvimwewo. Zvinhu izvi zvine kuomarara uye kuomarara kuri nani, kuomarara kwakanyanya kwekupisa kupfuura simbi dzakagadzirwa nekabhoni, ma layers akaomarara kupfuura simbi dzakagadzirwa nekabhoni, uye kusakara zvakanaka uye kuramba ngura, zvichikonzera kugara kwenguva refu uye mitengo yakakwira kupfuura simbi dzakagadzirwa nekabhoni. Nekuda kwekugara kwenguva refu kwesimbi isina ngura, huwandu hwekutsiva hwakaderera uye nekudaro mutengo patani wakaderera.
Kazhinji, chinhu chinoshandiswa pakugadzira ring die pellet mill isimbi yakagadzirwa nesimbi isina ngura uye zvinhu zvesimbi isina ngura.
2.Chiyero chekumanikidzwa kwe pellet mill die
i=d/L
T=L+M
M ndiko kudzika kwegomba rakaderedzwa
Chiyero chekumanikidzwa (i) chiyero chedhayamita yegomba rekufa (d) uye kureba kwakakodzera (L) kwedhayi.
Zvichienderana nehunhu hwezvinhu zvakabikwa, chiyero ichi i8-15, Mushandisi anosarudza chiyero chekumanikidzwa kwedhishi, uye anogadzirisa chiyero chekumanikidzwa chakanangana, senge kusarudza chiyero chekumanikidzwa chakaderera zvishoma, izvo zvinobatsira kuwedzera kubuda, kuderedza kushandiswa kwesimba, kuderedza kupera kwemuchina werin'i, asiwo kuderedza mhando yezvikamu, senge pellets haina kusimba zvakakwana, chitarisiko chakasununguka uye kureba kwakasiyana, uye mwero wehupfu wakakwira.
3.Mwero wekuvhura kwemhete inofa
Mwero wekuvhurwa kwediyi yepellet mill ihuremu hwenzvimbo yese yegomba rekufa kune nzvimbo yese inoshanda yediyi. Kazhinji, mwero wekuvhurwa kwediyi wakakwira, goho rezvimedu rakawedzera. Pasi pepfungwa yekuona simba rediyi, mwero wekuvhurwa kwediyi yerin'i unogona kuvandudzwa zvakanyanya sezvinobvira.
Kune zvimwe zvinhu zvakagadzirwa, kana paine chiyero chakanaka chekumanikidzwa, madziro echigayo chepellet akatetepa zvakanyanya, zvekuti simba remadi harina kukwana, uye chiitiko chemadi anoputika chichaonekwa mukugadzirwa. Panguva ino, ukobvu hweringi yedhiyi hunofanira kuwedzerwa pasi pepfungwa yekuona kuti gomba redhiyi rinoreba zvakanaka.
4.Kufananidza pakati pe pellet mill die ne roller
Ndiyo tekinoroji inonyanya kukosha yekuvandudza kushanda kwegranulation uye kuwedzera hupenyu hwedhi. Inofanira kusanganisira zvinhu zvina:
- Dhiya reringi idzva rine roller itsva yekumanikidza, dzivisa kushandisa roller yekumanikidza zvakanyanya.
- Zvichienderana nemhando yezvinhu, hunhu hwemhando yemuchina hwekusarudza mhando dzakasiyana dzechinotenderera chinodzvanya, kuitira kuti pave nekubudirira kwakanyanya kwekubvisa pakati pedhi neroro.
- Chinokosha pakukwana kwemukana ndiko kugadzikana uye musimboti ndewekuti: pasina kukanganisa kugona, edza kuzorora.
- Dzora kumhanya kwekudyisa, gadzirisa nzvimbo refu uye pfupi yekudyisa scraper kuti udzore nzvimbo yekudyisa, kugoverwa kwezvikamu zvezvinhu.
5.Kugadziriswa kwemafuta emugayo wepellet
Maburi edhiraivha anorema zvikuru kana tichitarisa michina yekugadzirisa nekugadzirisa, uye kana iri simbi isingatsvi, mabhora epfuti akakosha uye michina yekurapa kupisa kwevacuum inodiwa kuti igadzire madhiraivha edhiraivha emhando yepamusoro. Maitiro akanaka ekudzima dhiraivha yedhiraivha inodziya zvakanyanya anogona kuvandudza kuomarara, kuomarara, kuramba kukwesha, simba rekuneta uye kusimba kwesimbi. Zvisinei, kugona kuvimbisa kuomarara kwakaringana kwegomba rega rega kunoda hunyanzvi hwepamusoro hwekugadzirisa uye ruzivo rwakakura.
6.Kuomarara kwemadziro emukati megomba remafa
Kukombama pamusoro pechinhu chimwe chete chinoratidzawo kunaka kwe ring die. Kazhinji, kukosha kudiki kwekukombama kwemukati memadziro emukati kuchaita kuti ring die ikwane zvakanaka, kuderedza kupera uye kuwedzera hupenyu hwe ring die, asi mutengo wekugadzirisa ring die uchawedzera.
Kuomarara kwegomba reringi kunokanganisawo chiyero chekumanikidzwa uye kuumbwa kwezvikamu, pamwe nekubudirira kwekugadzirwa. Pachiyero chimwe chete chekuomarara kweringi, kukosha kwekuomarara kushoma, kuramba kwekubvisa machipisi ehuni kana chikafu kunoderedza, kubuda kwemvura kwakapfava, kunaka kwemapellets anogadzirwa kunowedzera uye kushanda kwekugadzira kwakakwira. Kugadziriswa kwakanaka kwegomba reringi kunogona kusvika kuma microns 0.8-1.6, kuomarara kweringi kunosvika ma microns 0.8, muchina chaiwo uri pazvinhu zvinoraswa, hapana kukuya.
