Parizvino, China inobhadhara zvakanyanya kuchengetedza kwezvakatipoteredza uye kuchengetedza simba.Panyaya yekudzika kwekugadzirisa marasha zviwanikwa, vatengi vazhinji havazivi kuti ndezvipi zviri nani pakusarudzwa kwe marasha emarasha vertical roller chigayo uye bhora chigayo chemarasha akapwanyika.Mune zvinotevera, HCM yakaongorora maitiro emarasha, ayo anobatsira kusarudzo yemutengi yechigayo chekuya.

HLMmarasha emarasha vertical roller chigayo 

1. Nekuda kwekusiyana kwemhando yemhando yemarasha uye bhailer inoshandiswa, zvinodiwa zvemarasha particle size zvakasiyana.Kazhinji, chiyero chekuongorora chinenge 90% pa200 meshes.Midziyo yekukuya inofanira kukwanisa kugadzirisa kunaka;

2. Kazhinji, marasha emarasha haasi akaoma zvakanyanya.Kazhinji, marasha ane hunyoro hunodarika 15%, uye lignite inotosvika 45%.Naizvozvo, iyo marasha pulverizing midziyo inofanirwa kukwanisa kuchinjika kune yakakwira hunyoro zvinhu uye kuomesa zvinhu uku uchikuya.Hazvidikanwi kugadzira imwe yakaoma yakaoma kuti iwedzere kuomesa;

3. Marasha ane mvura inopisa inopfuta, uye marasha pachawo anogona kutsva, saka zvinodzivirira moto uye matanho ekudzivirira kuputika anofanira kutorwa panguva yekukuya;

4. Marasha ane tsvina yakaoma uye yakaoma kukuya, iyo inofanirwa kugadzirisa kune yakaoma uye yakaoma kugaya tsvina panguva yekukuya;

Chigayo chebhora kanamarasha emarashavertical roller chigayokugadzirira marasha akapwanyika?Kunyangwe ese ari maviri akapwanyika marasha akatwasuka akamira akatwasuka chigayo uye bhora chigayo chinogona kugadzika marasha zvakadzika, kubva pakuongororwa kwehunhu hwemarasha, iyo yakatwasuka roller chigayo chemarasha akapwanyika chakanyanya kukodzera nekuda kwezvikonzero zvitatu:

Chekutanga, iyo yakapwanyika marasha yakatwasuka roller chigayo inotora yakasarudzika nzira yekugadzira uye chimiro, iyo inogara munzvimbo diki, ine guruva shoma uye ruzha panguva yekugadzira, uye inogadzira marasha akaputswa ane hunyanzvi hwekuita giredhi uye kuita kwakanakisa kupisa.

Chechipiri, kana zvichienzaniswa nebhora regiyo rechiyero chimwe chete, kushandiswa kwesimba kwemarasha vertical roller mill kunogona kuchengetedza 20 ~ 40%, kunyanya kana hunyoro hwemarasha hwakakura.Pamusoro pezvo, iyi vertical roller mill inotora mhepo yekutsvaira.Nekugadzirisa kutonhora kwemhepo inopinda uye huwandu hwemhepo, marasha akasvibira ane unyoro kusvika ku10% anogona kukuyiwa nekuomeswa.High air volume inoshandiswa kusangana nezvinodiwa zvekuomeswa nehunyoro hwepamusoro, pasina kuwedzera michina yekubatsira.

Chechitatu, iyo pulverized coal vertical roll mill inobatanidza maitiro mashanu ekupwanya, kukuya, kuomesa, kusarudzwa kwehupfu uye kutakura.Iyo nzira iri nyore, marongerwo akazara, nzvimbo yepasi inenge 60-70% yebhora mill system, uye nzvimbo yekuvaka inenge 50-60% yebhora mill system.

Chinhu chinonyanya kukosha ndechekuti pulverized coal vertical roller millinotora yakakwira-inoshanda dynamic poda concentrator, iyo ine yakakwira poda yekusarudzika uye hombe yekugadziridza kamuri.Kunaka kwekusarudzwa kwehupfu hunogona kusvika pasi pe3% ye 0.08 mm sieve yakasara, iyo inogona kuzadzisa zvinodiwa zvehunyoro hwemhando yakaderera yemarasha kana anthracite mukuya mumutsetse wekugadzira simenti.
