Yuav tsum muaj dej khov nab kuab yog xav tau los tsim cov dej khov qhuav, thiab cov pa roj hmab muaj ntau yam khoom siv. Cov kev qhia tshwj xeeb ntawm cov pelletizers yog feem ntau yog kev txiav txim los ntawm lawv lub peev xwm ntau tag nrho. Piv txwv li, peb tus TCM 25- Ib nplooj loj heev ntawm lub peev xwm ntawm 30k 1}} Ib lub sijhawm muaj peev xwm ntau dua ntawm 60kg qhuav. Ntawm chav kawm, cov no yog cov nplov me me. Nruab nrab lossis loj cov pa roj hmab dej khov tuaj yeem tsim ntau pua ntawm cov dej khov uas qhuav ib teev, lossis ntau dua.
Cov khoom siv raw rau kev ua cov dej khov qhuav yog ua kua CO2. Kua roj ua kua roj ua kua nrawm nyob rau hauv kev txo qis los ntawm cov pa roj carbon dioxide sai sai (zoo ib yam li cov dej khov nab kuab (zoo ib yam li cov dej khov nab kuab). Cov dej khov qhuav yog nias rau hauv cov dej khov qhuav ntawm cov khoom sib txawv (thaiv cov dej khov qhuav, kos kom qhuav dej khov, thiab lwm yam) los ntawm cov pa khov kho.
Vim tias ua kua Co2 yuav tsis hloov pauv hloov mus rau hauv dej khov qhuav thaum nws tau hloov kho cov dej khov tau dhau los ua qhov ntsuas tau yooj yim rau kev ntsuas cov khoom siv khov kho kom zoo. Cov dej khov ua dej khov los ntawm peb cov pelletizer qhuav tuaj yeem ua siab ntev li 40-45%, uas tau mus txog qib ua hauv kev lag luam.
