Iyunithi ye-vacuum feeder ye-ZKS isebenzisa impompo yomoya ye-whirlpool ekhupha umoya. Indawo yokungena yempompo yemathiriyeli yokufunxa kunye nenkqubo yonke yenziwe ibekwimo yevacuum. Iinkozo zomgubo wezinto zifunxwa kwimpompo yemathiriyeli kunye nomoya ojikeleze kwaye zenziwe ukuba zibe ngumoya ohamba ngezinto. Ukudlula ityhubhu yezinto zokufunxa, bafika kwi-hopper. Umoya kunye nezinto zohlulwe kuyo. Izixhobo ezahluliweyo zithunyelwa kwisixhobo sokufumana izinto. Iziko lolawulo lilawula i-"on / off" ye-valve ye-pneumatic triple yokutya okanye ukukhupha izinto.
Kwiyunithi ye-vacuum feeder ifakwe umoya ocinezelweyo ngokuchasene nesixhobo sokuvuthela. Xa ukhupha imathiriyeli ngalo lonke ixesha, i-pulse yomoya ecinezelweyo ivuthela ngokuchaseneyo nesihluzo. Umgubo oncanyathiselwe kumphezulu wesihluzo uyavuthelwa ukuqinisekisa imathiriyeli eqhelekileyo yokufunxa.
