Cov kauj ruam tseem ceeb hauv kev tsim cov hmoov limestone yog sib tsoo. Cov txheej txheem tseem ceeb yog raws li nram no:
Raw Ore → Refining → Crushing (Lub puab tsaig Crusher) → Sib tsoo (Key Kauj Ruam) → Classification → Sau → Ntim
Crushing: Loj pieces ntawm limestone yog crushed rau hauv me me pieces (piv txwv li, ob peb centimeters).
Kev Sib Tsoo: Cov pob zeb me me yog hauv av rau hauv cov hmoov siv cov khoom sib tsoo tshwj xeeb. Qhov no yog kauj ruam tseem ceeb tshaj plaws.
Kev faib tawm: Cov hmoov av yog tshuab los ntawm cov cua ntws thiab dhau los ntawm kev ntsuas (chav kawm). Cov hmoov zoo tsim nyog raug xaiv, thaum cov hmoov coarse raug xa rov qab rau kev sib tsoo ntxiv.
Sau: Cov hmoov uas tsim nyog tau sau los ntawm lub tshuab cua daj cua dub thiab cov mem tes -jet hnab lim.
Main Sib Tsoo Khoom:
Raymond Mill (Pendulum Mill): Feem ntau siv, haum rau kev ua cov hmoov ntawm 80-400 mesh.
Vertical Mill: Loj, npaum, tsis muaj zog noj, haum rau loj- teev ntau lawm (xws li, fais fab nroj tsuag desulfurization tus neeg sawv cev npaj).
Pob Zeb: tuaj yeem tsim cov khoom zoo, tab sis kev siv hluav taws xob yog qhov siab.
Ultrafine ntsug zeb / nplhaib cov menyuam zeb: siv los tsim cov hmoov ultrafine nrog mesh loj ntawm 800 lossis loj dua.
