Nkag siab txog Kev Sib Tw Hnav hauv Coal & Coke Crushing

---

Coal thiab coke ua rau hnav cov txheej txheem uas sib txawv ntawm qhov nyuaj -pob zeb daim ntaub ntawv, thiab kev nkag siab yuam kev ntawm qhov sib txawv no yog qhov feem ntau ntawm kev xaiv hnav tsis raug hauv ntu no.

• 1. Tsis tshua muaj kev cuam tshuam, tsis tu ncua abrasion.

  Coal thiab coke yog cov ntaub ntawv mos uas ua rau muaj kev cuam tshuam me ntsis ntawm qhov chaw crushing piv rau granite los yog hlau ore. Cov txheej txheem hnav tseem ceeb yog qis- kev nyuaj siab puas: zoo, angular ntxhia hais - feem ntau quartz thiab av nplaum cov ntxhia hauv cov hmoov tshauv ntawm cov thee, thiab cov pa roj carbon zoo nyob rau hauv coke - rov khawb thiab erode ntawm hnav lub sijhawm. Qhov no tsawg-kev nyuaj siab abrasive hnav tsoos tsho nyiam cov ntaub ntawv nrog cov tawv tawv tawv, tsis muaj kev cuam tshuam hnyav. Raws li qhov tshwm sim, cov austenitic manganese steels (Mn18, Mn22) uas ua tau zoo nyob rau hauv nyuaj- pob zeb mining daim ntawv thov - qhov twg lawv ua hauj lwm- kev coj cwj pwm hardening yog qhib los ntawm siab - cuam tshuam loads - tsis zoo sib xws rau cov thee crushing {14} cov txheej txheem tsis txaus, vim tias qhov tsis txaus qhib kev ua hauj lwm- hardening transformation. Manganese steel nyob rau hauv qis- cuam tshuam cov kev pabcuam thee hnav sai heev los ntawm kev puas tsuaj ntawm qhov chaw uas tsis muaj zog rau nws lub peev xwm.

• 2. Mineral impurity cov ntsiab lus yog qhov tseem ceeb sib txawv.

  Cov thee nyoos muaj cov hmoov tshauv ntxhia hauv qhov sib piv ntawm 5% hauv siab - thermal thee mus rau 30-40% qis dua - qib khiav- ntawm - kuv cov khoom noj. Cov minerals tseem ceeb - quartz (SiO₂, Mohs 7), feldspar, thiab pyrite - yog qhov nyuaj tshaj li cov thee matrix thiab yog lub luag hauj lwm rau feem ntau ntawm abrasive hnav ntawm crusher nto. Lub thee nrog 15% tshauv thiab 60% quartz nyob rau hauv cov ntxhia feem nthuav qhia qhov hnyav hnyav dua ib puag ncig dua li cov thee nrog 10% tshauv thiab feem ntau cov av nplaum. Coke los ntawm roj av refining feem ntau muaj cov hmoov tshauv qis dua li cov thee tab sis nqa cov pa roj carbon monoxide zoo nrog cov pob txha ntse ntse uas ua kom muaj qhov sib xws tsawg- kev ntxhov siab puas.

3. High throughput amplifies hnav tus nqi.

Ntawm 1,000–3,000 t / h, lub thee npaj cog cov txheej txheem ntau dua tonnage los ntawm nws cov crusher hnav qhov chaw nyob rau ib hnub tshaj li ntau nyuaj- pob zeb quarries txheej txheem ib lub lim tiam. Txawm tias kev txhim kho tus nqi coj mus los ntawm 10-15% ib tonne txhais tau tias txo qis hauv cov khoom siv txhua xyoo thiab hloov pauv- tawm ntawm kev ua haujlwm.

4. Loj loj thiab tramp khoom txaus ntshai.

Khiav- ntawm- kuv cov thee feem ntau muaj lub ru tsev pob zeb, hlau pob zeb, thiab qee zaus tramp hlau los ntawm cov khoom siv mining. Hnav cov khoom siv rau cov thee crushing yuav tsum khaws cov toughness txaus kom muaj sia nyob qee lub sij hawm cuam tshuam los ntawm cov kev cuam tshuam hnyav dua yam tsis muaj kev tawg yooj yim - thawj hom tsis ua haujlwm rau siab heev -hardness, qis- cov ntaub ntawv toughness nyob rau hauv qhov chaw no.

Kev siv cov thee thiab coke siv ntau hom crusher ntau dua li nyuaj- pob zeb mining, nrog rauj crushers thiab nplhaib granulators dominating thee npaj, thiab cov menyuam crushers tau siv dav rau ob qho tib si thee thiab roj av coke hauv kev tswj - khoom- loj daim ntawv thov.
