Mineral loj crusheryog ib qho khoom siv uas siv ob pawg ntawm cov neeg tsav tsheb sib cais kom tawg cov ntaub ntawv los ntawm extrusion quab yuam thiab sib tsoo shear quab yuam tsim los ntawm cov txheeb ze sib hloov, uas tuaj yeem siv rau kev nplua crushing ntawm ores, pob zeb thiab cov ntaub ntawv refractory nrog siab thiab nruab nrab hardness hauv cov ntxhia ua, tshuaj lom neeg kev lag luam, cement, refractory cov ntaub ntawv, abrasives, tsev cov ntaub ntawv thiab lwm yam kev lag luam sectors. Nyob rau hauv cov txheej txheem ua hauj lwm ntawm ntxhia sizer crusher, cov menyuam hniav yog ib qho tseem ceeb thiab yooj yim rau zom ib feem, uas feem ntau tshwm sim hnav tshwm sim. Daim ntawv no tsuas yog qhia txog kev tiv thaiv ntawm cov menyuam hniav hnav.
1) Ua kom lub zog ntawm cov hniav yob
Txhawm rau ua kom lub zog ntawm cov hniav yob, surfacing nto ntawm cov hniav yob kom lub hardness ntawm cov hniav nto mus txog HRC58 los yog siab dua.
2) surfacing ntawm yob hniav nto
Vim cov menyuam cov hniav ntawmntxhia pob zeb crusheryog ua los ntawm siab manganese steel alloy steel, qhov vuam kev ua tau zoo kuj tsis zoo. Cov ntsiab lus siab yog xav tau rau kev xaiv cov khoom siv vuam electrode thiab kev tsim kho saum npoo. Tom qab xaiv qhov tsim nyog hnav- tiv thaiv electrode, surfacing yog nqa ncaj qha rau ntawm qhov chaw ntawm cov hniav yob. Rau cov hniav siab, 5 hli hloov txheej thiab 15 hli hnav- txheej tiv thaiv yog siv rau saum npoo, thiab rau cov hniav qis, 2 hli ~ 5 hli kho yog nqa tawm.
3) Tsim nyog faib cov hniav siab thiab qis
Vim qhov txawv txav ntawm cov menyuam cov hniav, tag nrho cov hniav yog hauv av rau tib qhov siab, tsis tuaj yeem paub qhov txawv ntawm cov hniav qub thiab cov hniav qis ntawm qhov chaw tshwj xeeb. Raws li tus naj npawb thiab layout hauv paus ntsiab lus ntawm cov hniav siab thiab cov hniav tsis tshua muaj, cov txheej txheem kev faib khoom tuaj yeem tsim tau, thiab qhov chaw siab ntawm cov hniav tuaj yeem raug cim, yog li kom raug tsim hauv vuam.
4) Surfacing txoj kev
Ua ntej, cov hniav nyiaj hniav kub ntawm cov pob zeb loj crusher raug tshem tawm ntawm lub crusher rotor thiab nteg tiaj tus. Polish tag nrho cov seem kom surfacing nrog lub tshuab polishing. Dc vuam tshuab yog saws, cov vuam kab yog thim rov qab, thiab cov txheej txheem vuam surfacing yog saws. Tam sim no ntawm hnav- txheej tiv thaiv yog tswj ntawm 150 ~ 180A, thiab tam sim no ntawm kev hloov txheej yog tswj ntawm 90 ~ 110A. Tswj qhov kub ntawm lub vuam txheej hauv qab 100 degrees Celsius, txheej txheej txheej vuam mus rau qhov xav tau tuab, ib txheej tuab yog tswj tsis pub dhau 1.5mm ~ 2.0mm.
