1. Mchenga: Yang'anani kwambiri pakuwunika mchenga wa fineness modulus, kachulukidwe ka tinthu, matope, kuchuluka kwa matope, kuchuluka kwa chinyezi, ma sundries, ndi zina zambiri. Mchengawu uyenera kuunikiridwa powona zizindikiro monga matope ndi matope, komanso mtundu wa mchenga uyenera kuweruzidwa poyamba ndi njira ya "kuwona, kukanikiza, kupukuta ndi kuponyera".

(1) "Tawonani", gwirani mchenga wochuluka ndikuuyala m'manja mwanu, ndipo yang'anani kufanana kwa kugawa kwa mchenga wonyezimira komanso wabwino. Pamene yunifolomu kugawa particles pa misinkhu yonse, ndi bwino khalidwe;

(2) "Pinch", madzi omwe ali mumchenga amatsinidwa ndi manja, ndipo kulimba kwa mchenga kumawonedwa pambuyo potsina. Mchengawo umakhala wothina kwambiri, madziwo amakhala okwera kwambiri, ndipo mosemphanitsa;

(3) “Tsukani”, gwirani mchenga m’dzanja lanu, pukutani ndi zikhato zonse ziwiri, kuwomba m’manja mopepuka, ndi kuwona matope akumamatira pachikhatho cha dzanja lanu. ;

(4) “Kuponya”, mchenga utatsinidwa, uponye m’dzanja lamanja. Ngati mchenga wa mchenga suli womasuka, ukhoza kuweruzidwa kuti mchengawo ndi wabwino, uli ndi matope kapena uli ndi madzi ambiri.

2. Mwala wophwanyidwa: yang'anani poyang'ana zizindikiro za miyala, kugawanika kwa tinthu, matope, matope, matope opangidwa ndi singano, zinyalala, ndi zina zotero, makamaka kudalira njira yodabwitsa ya "kuwona ndikupera".

(1) "Kuyang'ana" kumatanthawuza kukula kwa tinthu tating'ono ta mwala wophwanyidwa ndi kufanana kwa kugawidwa kwa miyala yamtengo wapatali yokhala ndi tinthu tating'ono tosiyanasiyana. Zitha kuweruzidwa poyamba ngati kugawanika kwa mwala wosweka ndi wabwino kapena woipa, ndipo kugawidwa kwa tinthu tating'onoting'ono tonga singano titha kuyerekezedwa. Mlingo wa chikoka cha mwala wosweka pa workability ndi mphamvu konkire;

Mlingo wa matope ukhoza kufufuzidwa poyang'ana makulidwe a fumbi la fumbi lomwe limayikidwa pamwamba pa miyala; mlingo wa kugawira tirigu pamwamba pa miyala yoyera ukhoza kufufuzidwa mwa kuphatikiza ndi "kugaya" (miyala iwiri yotsutsana) kuti mufufuze kuuma kwa miyala. .

Onani ngati pali tinthu tating'ono ta shale ndi chikasu pamwala, ngati pali tinthu tambiri ta shale, sizipezeka. Pali mitundu iwiri ya tinthu tachikasu pakhungu. Pamtunda pali dzimbiri koma palibe matope. Mtundu uwu wa tinthu ulipo ndipo sudzakhudza mgwirizano pakati pa mwala ndi matope.

Pakakhala matope achikasu pamwamba pa tinthu tating'onoting'ono, tinthu tating'onoting'ono tating'onoting'ono kwambiri, tidzakhudza kwambiri mgwirizano pakati pa mwala ndi matope, ndipo mphamvu yopondereza ya konkire idzachepetsedwa ngati pali tinthu tambirimbiri.

3. Admixtures: konkire admixtures, kudzera zithunzi kuonerera mtundu, akhoza pafupifupi kuweruzidwa ngati naphthalene (bulauni), aliphatic (magazi ofiira) kapena polycarboxylic asidi (colorless kapena kuwala chikasu), ndithudi, palinso naphthalene ndi mafuta Chogulitsacho (chofiira chofiira) pambuyo pophatikizana chikhoza kuweruzidwa ndi fungo la mankhwala ochepetsera madzi.

4. Zosakaniza: Khalidwe lakumva la phulusa la ntchentche limayesedwa makamaka ndi njira yosavuta ya "kuwona, kukanikiza ndi kuchapa". "Kuyang'ana" kumatanthauza kuyang'ana mawonekedwe a phulusa la ntchentche. Ngati tinthu ndi ozungulira, zikutsimikizira kuti ntchentche phulusa ndi original mpweya ngalande phulusa, apo ayi ndi phulusa pansi.

(1) "Pinani", kutsina ndi chala chachikulu ndi chala cholozera, kumva kuchuluka kwa mafuta pakati pa zala ziwiri, mafuta ochulukirapo, phulusa la ntchentche limakhala lowoneka bwino, mosiyana, mokulirapo (fineness).

(2) “Kutsuka”, gwira phulusa la ntchentche lodzaza manja ndi dzanja kenako nkutsuka ndi madzi apampopi. Ngati zotsalira zomwe zimayikidwa pa chikhatho cha dzanja zimatsukidwa mosavuta, zikhoza kuweruzidwa kuti kutaya pamoto wa ntchentche phulusa ndi kochepa, mwinamwake zotsalirazo ndizochepa. Ngati kuli kovuta kusamba, zikutanthauza kuti kutaya pa kuyaka kwa ntchentche phulusa ndi mkulu.

Maonekedwe amtundu wa phulusa la ntchentche amathanso kuwonetsa mosalunjika mtundu wa phulusa la ntchentche. Mtundu wake ndi wakuda ndipo mpweya wa carbon ndi wochuluka, ndipo madzi amafunikira kwambiri. Ngati pali vuto lachilendo, kuyezetsa kwa chiŵerengero chosakanikirana kuyenera kuchitidwa panthawi yake kuti muwone momwe madzi amagwiritsira ntchito, ntchito yogwirira ntchito, kukhazikitsa nthawi ndi mphamvu.

Maonekedwe a mtundu wa ufa wa slag ndi ufa woyera, ndipo mtundu wa ufa wa slag ndi wotuwa kapena wakuda, kusonyeza kuti ufa wa slag ukhoza kusakanikirana ndi chitsulo cha slag ufa kapena phulusa la ntchentche ndi ntchito yochepa.
