Ubudlelwano phakathi kokunwebeka kwamalahle kanye nenqubo yokukhiqiza amalahle ehlanzekile

I-elasticity yamalahle ibhekisela ekuguquguqukeni kwamalahle akhiqizwa amandla angaphandle, kanye nezinga lokubuyiswa kwe-deformation ngemva kokususwa kwamandla angaphandle.

Ukunwebeka kwamalahle ngokuvamile kuvezwa isilinganiso sokunwebeka esihlobene ngemva kokudilizwa kwama-briquette. Ukunwebeka okukhulu kwamalahle, ilahle lixega ngemva kokwakhiwa komshini bese kwehlisa amandla.

Ukunwebeka kwamalahle kuhlobene nalezi zinto ezilandelayo:

1, izinga lokuhlanganisa

Ngokwezinga lamalahle, amalahle ahlukaniswe i-peat, i-lignite, amalahle e-bituminous kanye ne-anthracite. Njengoba izinga lokuhlangana likhula, ukunwebeka kwamalahle kuyanda. Ukuqina kwe-anthracite.

2, izinga lembudumbudu

Emalahleni afanayo, izinhlayiya ezincane kakhulu, i-elastic eyengeziwe futhi impofu kakhulu ukwakheka.

3, umswakama wamalahle

Uhlobo olufanayo lwamalahle, ngokuvamile lapho umswakama wangaphandle umkhulu, kukhulu ukunwebeka kwawo.

Ngaphezu kwalokho, amaminerali emalahleni nawo anethonya elithile ekunwebekani. Amalahle ane-elasticity enkulu kunzima ukwakha, futhi amandla emva kokubumba nawo aphansi. Lapho isikhunta sikhululwa, sivame ukuqhekeka futhi sikhukhumale ngenxa yokwandiswa kwe-elastic, ngakho-ke amalahle ane-elasticity enkulu Zama ukunciphisa ukuqina bese ulungisa kabusha.

Impahla eluhlaza eyinhloko yebriquette ehlanzekile i-anthracite. I-anthracite ine-elasticity enkulu kanye ne-plasticity empofu. Ukuze unake lesi sici, naka izinto ezilandelayo ekukhiqizeni:

1, inqubo yokuchoboza

Ngemuva kokuchotshozwa, ubukhulu bezinhlayiya zamalahle kufanele bulawulwe ngaphansi kuka-3 mm, okungaphezu kuka-70% okungaphezu kuka-1 mm. Umkhawulo ongaphezulu wesayizi wezinhlayiyana ezishiwo ukuvimbela ukuchotshozwa kwesibili kwamalahle ekubumbeni futhi kuthinte amandla e-briquette. Umkhawulo ophansi oshiwo unenzuzo ekunciphiseni ukunwebeka phakathi kwezinhlayiya ngenkathi unciphisa inani le-binder eyengeziwe futhi uthuthukise ukusebenza okuvuthayo kwe-briquette.

Ngendlela, umswakama wamalahle ku-crusher ngokuvamile ulawulwa ngaphansi kwe-15%, ngaphandle kwalokho uzothinta umphumela wokuchoboza.

2, inqubo yokuxova

Inqubo yokuxova igama elijwayelekile lokuxuba nokuxova. Ukuxuba kuwukuxuba izinto eziningi kanye namanzi ngokufana ngokunyakazisa kwemishini.

Ukuxova ukusabalalisa amanzi ngokulinganayo kanye nokuhlanganisa phezu kwezinhlayiya zamalahle ukuze kukhangiswe eduze kwezinhlayiya zamalahle ukwenza ifilimu enamanzi. Ukwengeza, ubuningi bobuningi bezinto zamalahle bunganyuswa, ukunwebeka phakathi kwezinhlayiya zamalahle kungaqedwa, futhi ukubunjwa kulula.

Imishini yokuxova esetshenziswa kakhulu ihlanganisa izixube ze-twin shaft, izigayo zamasondo, ama-vertical kneader, njll.

3, inqubo yokuhlanza

Inqubo ye-deuteration iwukungena ngaphakathi kwe-binder ngaphakathi kwezinhlayiya zamalahle, futhi ngesikhathi esifanayo ukwandisa ukuminyana kwamalahle, ukuqeda ukuqina phakathi kwezinhlayiya zamalahle, nokwandisa amandla e-briquette.

Ezinye izintambo zokukhiqiza amalahle ezihlanzekile azinayo inqubo yokukhishwa. Uma ukhulisa ukuminyana kwamalahle futhi ususa ukunwebeka phakathi kwezinhlayiya zamalahle, u-Xiao Bian uncoma ukuthi ubheke amalahle isikhathi esithile ngaphambi kwenqubo yokubumba.

Isikhathi sokubilisa ngokuvamile amahora angama-24 futhi siyalungiswa njengoba izinga lokushisa lishintsha.

4, inqubo yokubumba

Lapho izinhlayiya zamalahle zicindezelwa, zizokhubazeka ngokunwebeka, futhi okokufaka kwamandla omshini okuvela emandleni kuzogcinwa ku-briquette. Lapho ingcindezi yokwakha iqedwa, le ngxenye yamandla izokhishwa, futhi umthamo we-briquette uzokhula. I-anthracite inokunwebeka okukhulu kanye nesilinganiso sokunwetshwa okuphezulu, ngakho ithatha ukubumba kwengcindezi ephansi, futhi ingcindezi yokubumba ngokuvamile ayidluli ku-25 MPa. Ukucindezela ngokweqile kudala imifantu ebusweni be-briquette, kunciphisa amandla nokumelana namanzi.
