Screenings miyala - ndalama chuma ntchito yomanga

Chifukwa cha processing zosiyanasiyana thanthwe cholinga yopanga mwala wosweka analandira mankhwala owonjezera - sifting. Iwo aumbike mwa pogawanikana pamawere pambuyo zatsalira sieving kupyolera sieve wapadera kwa kulekana kwa ting'onoting'ono. Ndipotu, Kupha chomenyedwa ndi lokha kagawo kakang'ono ka izo.

Malinga ndi katundu ofanana sifting feedstock. Monga chomenyedwa, izo amakhala ndi magawo monga osalimba, mawonekedwe, mphamvu, nkhani za fumbi ndiponso clays. Zimakhala laimu, lubwe, nsangalabwi, etc. Mtundu zimatengera pa thanthwe, chochokera umene ndi imvi, imvi wobiriwira, wofiira, pinki. Screenings fractionate mwala wosweka: laling'ono 1-3 mamilimita zazikulu ndi 10 mm.

Ngakhale kuti mlingo dropout ndi byproduct kupanga mwala wosweka, izo zikhoza kuganiziridwa wodziimira zomangila, amene chimagwiritsidwa ntchito. Tsopano, opanga ambiri amaona kuti ndi bwino kwambiri zosowa zawo m'malo mtengo mchenga sifting chomenyedwa kugula.

Ntchito dontho-outs

Poyerekeza ndi miyala screenings mtengo chuma, choncho ntchito kwambiri kuchepetsa ndalama ambiri ntchitoyo. Izo ntchito yopanga konkire ndi konkire katundu, kupanga mfundo zosiyanasiyana mapulani ndi slabs amaika mumsewu. Izi chuma particulate chofunika pamene chipangizo kusefera kachitidwe ayeretsedwa ndi madzi a Mankhwala oipitsa, mu kupanga wa phula kasakaniza, kupanga mapanelo kukongoletsa khoma ndi zipangizo zosiyanasiyana kuwamaliza.

Screenings lubwe miyala ndi chofunika mu kapangidwe malo kwa ulemerero wa mabedi maluwa ndi mabedi maluwa, kamangidwe munda ndi malo paki. Ndi pafupifupi zinyalala ufulu chuma wochezeka. Nthawi ntchito njira kukongoletsa munda, takambiranazi, osati mawonekedwe komanso mtundu. Alternating screenings zamitundu yosiyanasiyana, m'malo wotopetsa mayendedwe mbuye ❖ kuyanika ndi malo m'munda kulenga chithunzi lonse. Ngati chochuluka ❖ kuyanika kuteteza malire laling'ono, ndi madzi permeable zakuthupi si yagwa ngakhale yamphamvu.

M'nyengo yozizira nthawi sifting chomenyedwa kulikonse ntchito kukonkha zigawo poterera a m'misewu. Kapangidwe, kulemera yeniyeni ndi kukula mulingo woyenera kwambiri particles nkhani kupereka kwambiri odana Pepala tingati Komanso, Kupha otetezeka chilengedwe, chifukwa lili mulibe reagents mankhwala. Ikani ndi chuma zaphindu, makamaka ngati kasupe kusonkhanitsa zotsalira za yozizira yotsatira.

Mtengo wa dropout

Mtengo wa mtundu uwu wa mankhwala kumatengera zifukwa zingapo. Remoteness wa malo kupanga kumaloku, mtundu ndi mtundu wa screenings, kuchuluka kwa kotunga, ndalama zoyendera, etc. Pamene inu kugula zinthu n'kofunika amafuna kalata umoyo wa quality, zikalata kuti mosamala a miyala ndi mfundo anakhazikitsa ndi kuti Chofunika, izo lilibe radionuclides.

Low mtengo, durability, ndiponso ntchito zake zosiyanasiyana za ichi chochokera kwa processing wa miyala - ubwino waukulu mosamala ndi wotchuka mu zomangamanga ndi tsiku ndi tsiku.
