Hordhac kaolin
Kaolin ma aha oo kaliya macdanta dhoobada caadiga ah ee dabiiciga ah, laakiin sidoo kale waa macdan aan bir ahayn oo aad muhiim u ah.Waxa kale oo loo yaqaan dolomite sababtoo ah waa caddaan.Kaolin-ka saafiga ah waa caddaan, khafiif ah oo jilicsan, oo leh caag wanaagsan, caabbinta dabka, ka joojinta, xayeysiinta iyo waxyaabo kale oo muuqaal ah.Adduunku wuxuu qani ku yahay kheyraadka Kaolin-ka, iyadoo wadarta cadadkeedu dhan yahay ilaa 20.9 bilyan oo tan, kuwaasoo si ballaaran loo qaybiyo.Shiinaha, Mareykanka, Britain, Brazil, India, Bulgaria, Australia, Russia iyo dalal kale ayaa leh kheyraad kaolin oo tayo sare leh.Khayraadka macdanta ee Shiinaha ee Kaolin ayaa ka mid ah kuwa ugu sarreeya adduunka, iyada oo 267 goobood oo macdan laga soo saaray iyo 2.91 bilyan oo tan oo kayd ah oo la xaqiijiyay.
Codsiga kaolin
Kaolin-ka wax soo saarka dabiiciga ah waxaa loo qaybin karaa kaolin dhuxusha, kaolin jilicsan iyo kaolin bacaad ah saddex qaybood iyadoo loo eegayo tayada nuxurka, balaastiga, warqad ciid.Meelaha kala duwan ee codsiga ayaa la waydiistay shuruudaha tayada kala duwan, sida warqadaha waraaqaha ugu horreyntii waxay u baahan yihiin dhalaal sare, viscosity hooseeya iyo xoogga saarista xajmiga walxaha ganaaxa;Warshadaha dhoobada waxay u baahan yihiin caag wanaagsan, qaabaynta iyo cadaanka rasaasta;Baahida refractory ee refractoriness sare;Warshadaha dhaldhalaalka waxay u baahan yihiin ka-joojin wanaagsan, iwm. Dhammaan tani waxay go'aamisaa qeexida kaolin ee badeecada, kala duwanaanta noocyada.Sidaa darteed, dabeecada kheyraadka kala duwan, ayaa si weyn u go'aamisa jihada kheyraadka loo heli karo horumarinta warshadaha.
Guud ahaan, kaolin-ka dhuxusha ee gudaha (kaolin adag), ayaa aad ugu habboon horumarka sida kaolin-ka calcined, oo inta badan loo isticmaalo dhinaca buuxinta ee codsiyada kala duwan.Sababtoo ah cadaanka sare ee kaolin-ka, waxaa loo isticmaali karaa samaynta waraaqaha, gaar ahaan soo saarida warqadda dahaarka sare leh, laakiin guud ahaan looma isticmaalo kaligeed sababtoo ah ciidda kaolin ee calcined ayaa inta badan loo isticmaalaa si loo kordhiyo cadaanka, qiyaasta waa In ka yar ciidda la dhaqay ee warqad-samaynta.Kaolin aan dhuxusha lahayn (dhoobo jilicsan iyo dhoobo bacaad ah), oo inta badan loo isticmaalo daaha waraaqaha iyo warshadaha dhoobada.
Habka Shidida Kaolin
Falanqaynta qaybaha alaabta ceeriin ee kaolin
SiO2 | Al22O3 | H2O |
46.54% | 39.5% | 13.96% |
Kaolin budada samaynta barnaamijka xulashada mashiinka
Tilmaamaha (Mesh) | budo qafiif ah 325mesh | Ka-hortagga qoto-dheer ee budada ultrafine (600 mesh-2000 mesh) |
Barnaamijka xulashada qalabka | Warshad shiididda toosan ama raymond shiididda |
*Fiiro gaar ah: dooro mashiinka ugu muhiimsan si waafaqsan shuruudaha wax soo saarka iyo ganaaxa
Falanqaynta moodooyinka shiididda
1. Raymond Mill: Raymond Mill waa kharashyo maalgashi oo hooseeya, awood sare, isticmaalka tamarta yar, qalabku waa xasillooni, buuq yar;waa warshad wax lagu kaydiyo tamareed oo tayo sare leh oo loogu talagalay budada wanaagsan ee ka hooseeya 600mesh.
2.Vertical mill: qalab ballaaran, awood sare, si loo daboolo wax soo saarka ballaaran.Dheef-shiidka toosan waa xasillooni sare.Khasaaro: qalabku waa kharashyo maalgashi oo sarreeya.
Marxaladda I: Burburinta alaabta ceeriin
Maaddada kaolin ee weyn waxaa burburiya burburiyaha si ay u nuugaan ganaaxa (15mm-50mm) kaas oo geli kara mashiinka wax lagu shiidayo.
Marxaladda II: Shiidida
Walxaha yar yar ee kaolin-ka ah ee la jajabiyey waxa loo soo diraa hopper-ka kaydinta wiishku, ka dibna waxa loo diraa qolka wax lagu shiida ee shiidka si siman iyo qiyaas ahaan feederiyaha si loo shiido.
Marxaladda III: Kala saaridda
Alaabta la shiiday waxaa lagu qiimeeyay nidaamka darajooyinka, iyo budada aan u qalmin ayaa lagu qiimeeyay kala soocida oo lagu soo celiyaa mashiinka weyn si dib loogu shiido.
Marxaladda V: Ururinta alaabta la dhammeeyey
Budada u hoggaansamaya ganaaxa waxay ku socotaa dhuunta gaaska waxayna gashaa boodhka ururiyaha si loo kala saaro oo loo ururiyo.Budada dhammaatay ee la ururiyay waxa loo diri silo alaabta la dhammeeyay iyada oo loo sii marinayo aalladda gudbinta iyada oo la marsiinayo dekedda, ka dibna lagu baakadeeyo booyada budada ama baakadaha tooska ah.
Tusaalooyinka codsiga ee habaynta budada kaolin
Qalabka farsamaynta: pyrophyllite, kaolin
Ganaaxa: 200 mesh D97
Wax soo saarka: 6-8t/saacaddii
Qaabaynta qalabka: 1 set oo ah HC1700
Warshada wax lagu shiida ee HCM waa doorasho aad u xikmad badan in lala kaashado shirkad noocaas ah oo leh nidaam dammaanad qaadka iibka ka dib ah.Hongcheng kaolin wax shiididu waa qalab cusub oo lagu cusboonaysiinayo warshad dhaqameedka.Wax-soo-saarkeedu waa 30% - 40% ka sarreeya kii caadiga ahaa ee Raymond mill wakhti dheer ka hor, kaas oo si weyn u wanaajinaya waxtarka wax-soo-saarka iyo wax-soo-saarka unugga.Alaabooyinka la dhammeeyay ee la soo saaray waxay leeyihiin tartan suuqeed weyn waxayna aad caan ugu yihiin shirkadeena.
