Ukwethulwa okuningiliziwe kwendlela yokubumba ye-briquette ball press

Isikhundla esimele umshini wokunyathelisa i-briquette embonini yokunyathelisa ibhola ngeyokuqala futhi ehlanganiswe kakhulu, ngoba ukusetshenziswa kwezinsiza zamalahle e-China akunakuhlukaniswa nomshini wokunyathelisa i-briquetting. Njengamanje, izindlela ezivame ukusetshenziswa ezigayiwe zamalahle ikakhulukazi zifaka ukwakhiwa kokucindezela okubandayo kwe-binder kanye nokwakhiwa kokucindezela okubandayo ngaphandle kwe-binder.

1, ngokwakhiwa okubandayo okunamathelayo

Okusho ukuthi, i-binder yengezwa emalahleni ahlutshiwe bese icindezela-yakhiwe. Esimeni lapho ukubumba okungena-binderless okufana namalahle e-bituminous noma i-anthracite kunzima, indlela yokwenza umshini obandayo we-binder ngokuvamile isetshenziswa embonini. Njengamanje, iningi lama-briquette asetshenziswa embonini ye-ammonia yokwenziwa yaseShayina nawo asebenzisa le ndlela yokubumba, ngoba isibopho esifanelekile esinesilinganiso esikhulu esingu-5% kuya ku-20% siyengezwa emalahleni agayiwe alezi zinhlobo zamalahle, futhi kusetshenziswa ingcindezi yokubumba. ngesenzo se-binder. Ingancishiswa ibe yi-15 kuya ku-50 MPa, ngakho-ke kulula ukuyisebenzisa ngokwezimboni. Kodwa-ke, kufanele kuphawulwe ukuthi ngenxa yokusebenzisa ama-adhesives, izinkinga ezilandelayo zizokwenzeka:

(1) Ukunciphisa okuqukethwe kwekhabhoni engashintshi kubriquette, ikakhulukazi lapho kusetshenziswa izinto ezingaphili njengomcako, usimende nobumba;

(2) Ngokuvamile, intengo yesibophezelo iphezulu kunaleyo yamalahle agayiwe. Nakuba inani elisetshenzisiwe lincane, izindleko ze-briquette nazo zanda;

(3) I-binder ngokwayo idinga ukuphathwa, futhi kufanele ihlanganiswe ngokufanayo namalahle ahlutshiwe, futhi kamuva ihlanganiswe, njll., ukuze inqubo yokubumba ikhule futhi inqubo ibe yinkimbinkimbi;

(4) Inani le-briquette elisetshenziswa embonini likhulu, futhi inani lesibopho lidinga ukuba likhulu ngokulinganayo. Isibopho kufanele sibe nemithombo eyanele. Ngokusekelwe kulezi zimo, kuyadingeka ukuqinisa ucwaningo lwendlela yokubumba engena-binderless ngokombono wesikhathi eside. Vele, izinhlelo zokusebenza ezinokubumba okunamathelayo zizoqhubeka nokuvela.

2, akukho ukwakheka okubandayo kwe-binder

Okusho ukuthi, amalahle ahlutshiwe akhiwa ngaphandle kwanoma iyiphi i-binder nangesenzo samandla angaphandle. Le ndlela iye yasetshenziswa kabanzi emazweni amaningi ukwenza i-peat ne-lignite briquette njengamafutha asendlini noma amafutha ezimboni. Ngamalahle e-bituminous kanye ne-anthracite, ngenxa yezinga eliphezulu lamalahle, kunzima ukwakha amalahle ahlutshiwe ngaphandle kokunamathela. Njengamanje, inqubo yokubumba engena-binderless ayizange isetshenziswe kabanzi embonini, kodwa umsebenzi wokucwaninga kule ndawo awuzange uphazamiseke emhlabeni. Induku yamalahle emanzi ehlanzekile (induku yamalahle emanzi) esetshenziswa embonini ye-ammonia yokwenziwa yaseChina nayo iyisibonelo.

Ukubumba okuhlanganisiwe kwamalahle okuhlanganisiwe akudingi ukungezwa kwanoma yikuphi ukubopha, okungagcini nje ngokusindisa inani elikhulu lezinto zokusetshenziswa, kodwa futhi kugcina okuqukethwe kwekhabhoni yebriquette, nokwenza kube lula inqubo yokubumba, njll. isiqondiso esibalulekile sokuthuthukiswa.
