Okwangoku, iChina inika ingqwalasela ngakumbi ekukhuselweni kwendalo kunye nokugcinwa kwamandla.Ngokubhekiselele kwizixhobo ezinzulu zokucwangcisa amalahle, abathengi abaninzi abazi ukuba yeyiphi engcono ekukhetheni amalahle acoliweyo ilitye lokusila elithe nkqo kunye nebhola yokusila yamalahle acoliweyo.Oku kulandelayo, i-HCM ihlalutye iimpawu zamalahle, eziluncedo ekukhetheni umthengi wokusila amalahle.

HLMamalahle acoliweyo ilitye lokusila elithe nkqo 

1. Ngenxa yokwahluka kohlobo lokuthungwa kwamalahle kunye nebhoyila esetyenzisiweyo, iimfuno zobungakanani be-particle yamalahle ziyahluka.Ngokuqhelekileyo, izinga lokuhlola limalunga ne-90% kwi-200 meshes.Izixhobo zokugaya kufuneka zikwazi ukulungelelanisa ukucolwa;

2 Ngokuqhelekileyo, iibhloko zamalahle azikho izinto ezomileyo kakhulu.Ngokuqhelekileyo, amalahle aqulethe ngaphezu kwe-15% yokufuma, kwaye i-lignite ide ifikelele kwi-45%.Ke ngoko, izixhobo zokucolwa kwamalahle kufuneka zikwazi ukuziqhelanisa nezinto zokufuma eziphezulu kwaye zomise izinto xa zigaya.Akuyimfuneko ukuseka isomisi esahlukileyo ukunyusa inkqubo yokumisa;

3. Amalahle aqulethe amanzi avuthayo avuthayo, kwaye amalahle ngokwawo anokutsha, ngoko ke ukunqanda ilangatye kunye namanyathelo obungqina bokuqhuma kufuneka kuthathwe ngexesha lokusila;

4. Amalahle aqukethe ukungcola okunzima kwaye kunzima ukugaya, okufunekayo ukulungelelanisa ukungcola okunzima kwaye kunzima ukugaya ngexesha lokugaya;

Ibhola lokusila okanyeamalahle acoliweyoilitye lokusila elithe nkqoukulungiselela amalahle acoliweyo?Nangona yomibini ilitye lokusila elithe nkqo eligutyungelweyo le-roller kunye nebhola lokusila linokuqhubekekisa ngokunzulu amalahle, ukusuka kuhlalutyo lweempawu zamalahle, ilitye lokusila elithe nkqo lamalahle axonxiweyo lifanelekile ngakumbi ngezizathu ezithathu:

Okokuqala, ilitye lokusila eligutyungelweyo le-roller elithe nkqo lithatha inkqubo yemveliso ekhethekileyo kunye nolwakhiwo, oluhlala kwindawo encinci, lunothuli oluncinci kunye nengxolo ngexesha lemveliso, kwaye livelisa amalahle acoliweyo anomgangatho ophezulu wokusebenza kunye nokusebenza okubalaseleyo kokutsha.

Okwesibini, xa kuthelekiswa nelitye lokusila lomlinganiselo ofanayo, ukusetyenziswa kwamandla elitye lokusila elithe nkqo linokonga i-20 ~ 40%, ngakumbi xa ukufuma kwamalahle ekrwada kukhulu.Ukongeza, lo matshini wokusila othe nkqo wamkela umsebenzi wokutshayela umoya.Ngokulungelelanisa ubushushu bomoya ongenayo kunye nomthamo womoya, amalahle aluhlaza kunye nomswakama ukuya kwi-10% anokugaya kwaye omiswe.Umthamo womoya ophezulu usetyenziselwa ukuhlangabezana nemfuneko yokomisa ngomswakama ophezulu, ngaphandle kokongeza oomatshini abancedisayo.

Okwesithathu, ilitye lokusila elithe nkqo lidibanisa iinkqubo ezintlanu zokucolwa, ukucola, ukomisa, ukukhetha umgubo kunye nokuthutha.Inkqubo ilula, i-layout is compact, indawo yomgangatho imalunga ne-60-70% yenkqubo yokugaya ibhola, kunye nommandla wokwakha malunga ne-50-60% yenkqubo yokugaya ibhola.

Eyona nto ibalulekileyo kukuba ilitye lokusila elithe nkqoithatha i-powder concentrator ephezulu esebenzayo, enomsebenzi ophezulu wokukhetha umgubo kunye negumbi elikhulu lohlengahlengiso.I-fineness yokukhethwa kwe powder inokufikelela ngaphantsi kwe-3% ye-sieve ye-0.08 mm intsalela, enokuthi ihlangabezane neemfuno ze-fineness yobuninzi obuphantsi kwamalahle okanye i-anthracite yokugaya kumgca wokuvelisa i-samente.
