Pakadali pano, China ikuyang'ana kwambiri kuteteza chilengedwe ndi kusunga mphamvu. Ponena za kukonza kwambiri zinthu za malasha, makasitomala ambiri sakudziwa chomwe chili chabwino kusankha malasha ophwanyidwa mphero yozungulira yoyimirira ndi mphero ya mpira ya malasha ophwanyidwa. Mu zotsatirazi, HCM yasanthula makhalidwe a malasha, zomwe zimathandiza kasitomala kusankha mphero yophwanyira malasha.

HLMmalasha ophwanyidwa mphero yozungulira yoyimirira 

1. Chifukwa cha kusiyana kwa mtundu wa kapangidwe ka malasha ndi boiler yomwe imagwiritsidwa ntchito, zofunikira pa kukula kwa tinthu ta malasha ndizosiyana. Kawirikawiri, kuchuluka kwa zowunikira kumakhala pafupifupi 90% pa ma meshes 200. Zipangizo zopukutira ziyenera kukhala zokhoza kusintha kusalala kwake;

2. Kawirikawiri, makala a malasha si zinthu zouma kwambiri. Kawirikawiri, malasha amakhala ndi chinyezi choposa 15%, ndipo lignite imafika ngakhale 45%. Chifukwa chake, zida zopukutira malasha ziyenera kukhala zokhoza kusintha zinthu zouma kwambiri ndikuumitsa zinthuzo mukamapera. Sikofunikira kukhazikitsa chowumitsira china kuti muwonjezere njira yowumitsira;

3. Malasha ali ndi madzi oyaka moto, ndipo malasha okha ndi oyaka, kotero njira zoletsa moto komanso zopewera kuphulika ziyenera kutengedwa pogaya;

4. Malasha ali ndi zinthu zonyansa zolimba komanso zovuta kuperedwa, zomwe zimafunika kuti zigwirizane ndi zinthu zonyansa zolimba komanso zovuta kuperedwa panthawi yoperedwa;

Mphero ya mpira kapenamalasha ophwanyidwamphero yozungulira yoyimiriraKodi n'zotheka kukonza malasha ophwanyidwa? Ngakhale kuti mphero yozungulira yozungulira ya malasha yophwanyidwa ndi mphero yozungulira imatha kukonza malasha mozama, kuchokera ku kusanthula kwa makhalidwe a malasha, mphero yozungulira yozungulira ya malasha ophwanyidwa ndi yoyenera kwambiri pazifukwa zitatu:

Choyamba, mphero yozungulira ya malasha yopukutidwa imagwiritsa ntchito njira yapadera yopangira ndi kapangidwe kake, komwe kumakhala malo ochepa, kumakhala ndi fumbi ndi phokoso lochepa panthawi yopangira, ndipo kumapanga malasha opukutidwa okhala ndi ma grading apamwamba komanso magwiridwe antchito abwino kwambiri oyaka.

Chachiwiri, poyerekeza ndi mphero ya mpira ya sikelo yomweyo, mphamvu yogwiritsira ntchito mphero ya vertical roller mill yophwanyidwa ikhoza kusunga 20-40%, makamaka ngati chinyezi cha malasha chili chachikulu. Kuphatikiza apo, mphero iyi ya vertical roller imagwiritsa ntchito mpweya wotambasula. Mwa kusintha kutentha kwa mpweya wobwera ndi kuchuluka kwa mpweya, malasha osaphika okhala ndi chinyezi mpaka 10% amatha kuphwanyidwa ndikuumitsidwa. Mpweya wochuluka umagwiritsidwa ntchito kukwaniritsa zofunikira pakuuma ndi chinyezi chambiri, popanda kuwonjezera makina othandizira.

Chachitatu, mphero yozungulira ya malasha yophwanyidwa imaphatikiza njira zisanu zophwanya, kupukutira, kuumitsa, kusankha ufa ndi mayendedwe. Njirayi ndi yosavuta, kapangidwe kake ndi kakang'ono, malo apansi ndi pafupifupi 60-70% ya makina opangira mipiringidzo ya mpira, ndipo malo omangira ndi pafupifupi 50-60% ya makina opangira mipiringidzo ya mpira.

Chofunika kwambiri ndi chakuti mphero yozungulira yozungulira ya malasha yopukutidwaimagwiritsa ntchito chosungira ufa chogwira ntchito bwino kwambiri, chomwe chili ndi mphamvu zambiri posankha ufa komanso chipinda chachikulu chosinthira. Kusalala kwa kusankha ufa kumatha kufika pa 3% ya zotsalira za sieve ya 0.08 mm, zomwe zimatha kukwaniritsa zofunikira za kusalala kwa makala ambiri otsika mtengo kapena anthracite mu mzere wopanga simenti.
