I-PRETREATMENT DRUM & HEATING sisiqwengana sesixhobo esisetyenziswa kwimveliso yefektri ukunyanga imathiriyeli ekrwada. Ngokuqhelekileyo iqulethe i-barrel ejikelezayo yonyango kunye nenkqubo yokufudumeza. Ngethuba lokusebenza, izinto eziluhlaza zifakwe kwi-barrel ejikelezayo yonyango yangaphambili kwaye ifudunyezwe yinkqubo yokufudumala. Oku kunceda ukutshintsha izinto eziphathekayo okanye iikhemikhali zezinto eziluhlaza, okwenza kube lula ukuphatha ngexesha leenkqubo zokuvelisa ezilandelayo. Olu hlobo lwezixhobo ludla ngokusetyenziswa kwimichiza, ekusetyenzweni kokutya, kumayeza nakwamanye amashishini ukuphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.
