ZKS lub tshuab nqus tsev feeder yog siv lub tshuab nqus tsev twj tso kua mis tshem tawm cua. Lub inlet ntawm cov khoom nqus kais thiab tag nrho cov system yog ua kom nyob rau hauv lub nqus tsev vacuum. Cov hmoov nplej ntawm cov khoom yog absorbed rau hauv cov khoom siv kais nrog cua ambient thiab tsim los ua cua ntws nrog cov khoom. Dhau cov khoom nqus cov raj, lawv tuaj txog rau lub hopper. Cov huab cua thiab cov khoom sib cais hauv nws. Cov ntaub ntawv sib cais raug xa mus rau cov khoom siv tau txais. Lub chaw tswj hwm tswj qhov "on / off" lub xeev ntawm pneumatic triple valve rau kev pub lossis tso tawm cov ntaub ntawv.
Nyob rau hauv lub tshuab nqus tsev feeder lub compressed cua opposite tshuab yog haum. Thaum tso tawm cov ntaub ntawv txhua zaus, cov pa compressed pulse oppositely tshuab lub lim. Cov hmoov uas txuas rau saum npoo ntawm lub lim yog tshuab tawm kom ntseeg tau tias cov khoom siv absorbing zoo li qub.
