Pakalipano, China ikuyang'ana kwambiri chitetezo cha chilengedwe ndi kusunga mphamvu.Pankhani ya chuma chakuya processing malasha, makasitomala ambiri sadziwa kuti ndi bwino kusankha malasha opukutidwa vertical roller mphero ndi mpira mphero kwa malasha pulverized.Zotsatirazi, HCM yasanthula mikhalidwe ya malasha, yomwe ili yopindulitsa kwa kasitomala kusankha mphero yamalasha.

Zithunzi za HLMmalasha opukutidwa vertical roller mphero 

1. Chifukwa cha kusiyana kwa mtundu wa malasha ndi boiler yomwe imagwiritsidwa ntchito, zofunikira za kukula kwa tinthu ta malasha ndizosiyana.Nthawi zambiri, chiwonetsero chazithunzi ndi pafupifupi 90% pa ma meshes 200.Zipangizo zopera ziyenera kutha kusintha bwino;

2. Nthawi zambiri, malasha sizinthu zouma kwambiri.Nthawi zambiri, malasha amakhala ndi chinyezi chopitilira 15%, ndipo lignite imatha kufika 45%.Chifukwa chake, zida zopukutira malasha ziyenera kusinthira kuzinthu zachinyontho zambiri ndikuwumitsa zida pogaya.Sikoyenera kukhazikitsa chowumitsira chosiyana kuti muwonjezere kuyanika;

3. Malasha ali ndi madzi oyaka moto, ndipo malasha okha amatha kuyaka, choncho njira zochepetsera moto komanso zosaphulika ziyenera kuchitidwa panthawi yopera;

4. Malasha amakhala ndi zonyansa zolimba komanso zovuta kupukuta, zomwe zimafunika kuti zigwirizane ndi zodetsa zolimba komanso zovuta kugaya panthawi yopera;

Mpira mphero kapenamalasha opukutidwavertical roller mpheropokonza malasha?Ngakhale onse pulverized malasha ofukula wodzigudubuza mphero ndi mpira mphero akhoza mozama kupanga malasha, kuchokera kusanthula makhalidwe malasha, ofukula wodzigudubuza mphero ya malasha pulverized ndi abwino pa zifukwa zitatu:

Choyamba, mphero yopukutidwa ya malasha ofukula yozungulira imatenga njira yapadera yopangira ndi kapangidwe kake, komwe kamakhala kadera kakang'ono, kamakhala ndi fumbi komanso phokoso lochepa panthawi yopanga, ndipo imapanga malasha ophwanyidwa okhala ndi magwiridwe antchito apamwamba komanso kuyaka bwino kwambiri.

Chachiwiri, poyerekeza ndi mphero ya mpira wa sikelo yomweyo, kugwiritsa ntchito mphamvu kwa pulverized malasha ofukula wodzigudubuza mphero kumatha kupulumutsa 20-40%, makamaka pamene chinyezi cha malasha chimakhala chachikulu.Kuphatikiza apo, mphero yowongokayi imagwiritsa ntchito kusesa mpweya.Mwa kusintha kutentha kwa mpweya ukubwera ndi kuchuluka kwa mpweya, malasha aiwisi okhala ndi chinyezi mpaka 10% amatha kupukutidwa ndikuwumitsa.Kuchuluka kwa mpweya kumagwiritsidwa ntchito kukwaniritsa zofunikira zowumitsa ndi chinyezi chachikulu, popanda kuwonjezera makina othandizira.

Chachitatu, mphero yopukutidwa ya malasha yoyimirira imaphatikiza njira zisanu zophwanyira, kugaya, kuyanika, kusankha ufa ndi kayendedwe.Njirayi ndi yosavuta, masanjidwewo ndi ophatikizika, pansi ndi pafupifupi 60-70% ya mphero ya mpira, ndipo malo omangapo ndi pafupifupi 50-60% ya dongosolo la mphero.

Chinthu chofunika kwambiri ndi chakuti pulverized malasha ofukula wodzigudubuza mpheroimatenga cholumikizira champhamvu champhamvu cha ufa, chomwe chimakhala ndi kusankha kwa ufa wapamwamba komanso chipinda chachikulu chosinthira.Ubwino wa kusankha ufa ukhoza kufika osachepera 3% ya zotsalira za sieve za 0.08 mm, zomwe zingathe kukwaniritsa zofunikira za malasha otsika kwambiri kapena anthracite akupera mu mzere wopanga simenti.
