Koj tuaj yeem piav qhia qhov sib txawv ntawm qhuav thiab ntub kev sib tsoo?

Qhuav vs. ntub sib tsoo -

Dab tsi cais ob?

 

1 muaj (los yog tsis tuaj) ntawm cov kua

• Kev sib tsoo qhuav: cov zeb muaj tsuas yog cov khib nyiab los ua av thiab cov xov hlau sib tsoo (khoom, pas nrig, thiab lwm yam). Tsis muaj dej los yog lwm yam kua ntxiv.
• Kev sib tsoo ntub: muaj ntau yam dej sib tsoo (lossis qee zaum lwm cov kua) ntxiv rau ua cov slurry. Cov khib nyiab nyob rau hauv cov kua thaum txo qhov loj me.

 

2 Khoom Siv Cua

• Qhuav hluav taws xob khiav hauv huab cua. Kev sau cov plua plav, cua kev faib tawm, thiab qee zaum ua inert - roj pam yuav tsum tau.
• Ntub dej khiav hauv cov slurry; Tsis muaj hmoov av, tab sis twj, pob txha, thiab cov tuab tuab.

 

3 Particle - qhov loj me

• Cov Mills qhuav tuaj yeem ua lag luam txog kwv yees li 5-10 μm (ultrafine - pa taws heev, tab sis lub zog nce siab).
• Cov Mills ntub tau yooj yim mus txog sub - micron lossis txawm tias nano ntau thiab cov kua tawg) vim tias cov kua ua kom cov khoom tawg thiab ua kom tawg.

 

4 Zog tau noj Per Tonne ntawm cov khoom

• Kev sib tsoo qhuav feem ntau siv 20-30% ntau lub zog rau tib qho loj me me txo vim yog cov khoom noj kom zoo ntawm huab cua thiab qhov yuav tsum tau khiav tawm kom raug nplua.
• Kev sib tsoo ntub yog ntau lub zog - zoo rau kev sib tsoo zoo heev vim tias cov slurry ua raws li kev thauj khoom nruab nrab thiab ua kom lub zeb txias.

 

5Qhov thiab khoom rhiab

• Qhuav Mills tau kub; Kub -} Cov ntaub ntawv rhiab nkag tuaj yeem txwv lossis oxidize.
• Ntub ntub milling sau txias dua thiab tuaj yeem yog pam vov nrog kua roj (piv txwv li, roj, glycol) yog tias oxidation yog kev txhawj xeeb.

 

6 cov haujlwm hauv dej

• Khoom qhuav qhuav yog npaj rau lub tsheb thauj pneumatic, bagging, lossis qhuav kev faib tawm.

• Cov khoom ntub dej yog slurry; Nws tuaj yeem pub ncaj qha rau kev ua kom ncaj, (prictrication Circuit Court, lossis kev lim dej, lossis nws tau qhuav {{}}} cov kauj ruam uas ntxiv tus nqi.

 

7 plua av, kev nyab xeeb, thiab ib puag ncig

• Sib tsoo qhuav tsim cov hmoov av, suab nrov, thiab tawg kev pheej hmoo (tshwj xeeb nrog cov thee, cov organic, lossis cov hlau zoo). Cov tshuab nqus av thiab

Kev lag luam nce siab yog yuav tsum tau ua.

• Kev sib tsoo ntub yog cov hmoov av -} dawb thiab lowers tawg kev pheej hmoo, tab sis tsim kom cov neeg lim dej uas yuav xav tau kev kho mob.

 

8 hnav thiab txij nkawm

• Kev sib tsoo qhuav ua rau muaj kev ua kom muaj abrasive siab dua ntawm cov hnab thiab xov xwm tshaj vim yog cov kua tsis muaj lubricating.

• Ua kom ntub kev txo cov kev txhawj xeeb tab sis qhia txog kev txhawj xeeb corrosion yog tias cov kua yog xeb (piv txwv li, acidic slurries).

 

9 Daim Ntawv Thov Raug

• Qhuav: Maas raw zaub mov thiab ua tiav kev sib tsoo, thee pulverization rau lub zog hluav taws xob, cov ntxhia filleers, pigments, cocments, cereals.

• ntub dej: OE pob los yog sag mills ua ntej frolotation lossis leaching, ceramic ruam, xim pigments, ceelosuspensions, chocolate refining.

 

Txoj Cai - ntawm -}} Thumb txiav txim siab txiav txim siab

- Yuav tsum tau tsawg dua lossis sib npaug rau 10 μm uas tsis muaj kev poob qis kauj ruam? Qhuav feem ntau pheej yig dua.

- Xav tau sub - micron dispersion lossis cov txheej txheem yog twb ntub dej (flotation, leaching, ceramic plam)? Ntub yog txoj kev xaiv logical.
