Okwangoku, iTshayina inika ingqalelo ngakumbi kukhuseleko lokusingqongileyo kunye nokugcinwa kwamandla. Ngokuphathelele ukucubungula nzulu izixhobo zamalahle, abathengi abaninzi abazi ukuba yeyiphi engcono ekukhetheni amalahle acoliweyo i-roller mill ethe nkqo kunye ne-ball mill yamalahle acoliweyo. Kolu luhlu lulandelayo, i-HCM ihlalutye iimpawu zamalahle, nto leyo eluncedo kukhetho lomthengi lwe-coal grinding mill.

I-HLMamalahle acoliweyo i-roller mill ethe nkqo 

1. Ngenxa yokwahluka kohlobo lokwakheka kwamalahle kunye nebhoyila esetyenzisiweyo, iimfuno zobukhulu bamaqhekeza amalahle zahlukile. Ngokubanzi, izinga lokuvavanya limalunga ne-90% kwi-200 meshes. Izixhobo zokugaya kufuneka zikwazi ukulungisa ubunono;

2. Ngokubanzi, iibhloko zamalahle azizozinto zomileyo kakhulu. Ngokubanzi, amalahle anomswakama ongaphezulu kwe-15%, kwaye i-lignite ifikelela nakwi-45%. Ke ngoko, izixhobo zokucola amalahle kufuneka zikwazi ukuziqhelanisa nezinto zomswakama ophezulu kwaye zomise izinto ngelixa zisilwa. Akunyanzelekanga ukuba kumiselwe isixhobo sokomisa esahlukileyo ukuze kwandiswe inkqubo yokomisa;

3. Amalahle anamanzi atshayo, kwaye amalahle ngokwawo ayatsha, ngoko ke kufuneka kuthathwe amanyathelo athintela ilangatye kwaye angaqhumiyo ngexesha lokusila;

4. Amalahle aqulathe ukungcola okuqinileyo nokunzima ukukugaya, okufunekayo ukuze kuhlengahlengiswe ukungcola okuqinileyo nokunzima ukukugaya ngexesha lokugaywa;

I-ball mill okanyeamalahle acoliweyoi-roller mill ethe nkqoUkulungiselela amalahle acoliweyo? Nangona zombini i-pulverized coal vertical roller mill kunye ne-ball mill zinokucubungula amalahle nzulu, ukusuka kuhlalutyo lweempawu zamalahle, i-vertical roller mill yamalahle acoliweyo ifanelekile ngakumbi ngezizathu ezithathu:

Okokuqala, i-coal vertical roller mill ecoliweyo isebenzisa inkqubo yemveliso eyahlukileyo kunye nolwakhiwo, ethatha indawo encinci, inothuli oluncinci kunye nengxolo encinci ngexesha lokuveliswa, kwaye ivelisa amalahle acoliweyo anomgangatho ophezulu kunye nokusebenza kakuhle kokutsha.

Okwesibini, xa kuthelekiswa nebhola yombhobho yomlinganiselo ofanayo, ukusetyenziswa kwamandla kombhobho wokubhola ojikelezileyo welahle ocoliweyo kunokonga i-20-40%, ingakumbi xa umswakama wamalahle oluhlaza mkhulu. Ukongeza, lo mbhobho wokubhola ojikelezileyo usebenzisa umsebenzi wokutshayelela umoya. Ngokulungisa ubushushu bomoya ongenayo kunye nomthamo womoya, amalahle aluhlaza anomswakama ukuya kuthi ga kwi-10% anokugaywa aze omiswe. Umthamo womoya ophezulu usetyenziselwa ukuhlangabezana neemfuno zokomisa ngomswakama ophezulu, ngaphandle kokongeza oomatshini abancedisayo.

Okwesithathu, i-coal vertical roll mill ecoliweyo idibanisa iinkqubo ezintlanu zokutyumza, ukugaya, ukomisa, ukukhetha umgubo kunye nokuthuthwa. Le nkqubo ilula, uyilo luluncinci, indawo yomgangatho imalunga ne-60-70% yenkqubo ye-ball mill, kwaye indawo yokwakha imalunga ne-50-60% yenkqubo ye-ball mill.

Eyona nto ibalulekileyo kukuba i-roller mill yamalahle ecoliweyo nkqoIsebenzisa isixhobo sokuxinanisa umgubo esisebenza kakuhle kakhulu, esinokhetho oluphezulu lomgubo kunye negumbi elikhulu lokulungisa. Ubungakanani bokukhetha umgubo bunokufikelela ngaphantsi kwe-3% yentsalela yesihluzo ye-0.08 mm, enokwanelisa iimfuno zobungakanani bokugaywa kwamalahle okanye i-anthracite ekumgangatho ophantsi kumgca wokuvelisa isamente.
