Raws li lub helical ncej tig, cov khoom siv - txwv los ntawm nws tus kheej qhov hnyav thiab kev sib txhuam tsim tawm tsam cov phab ntsa trough- yog yuam kom nce mus raws hauv qab ntawm lub conveyor trough nkaus xwb nyob rau hauv lub thrust ntawm lub helical hniav. Qhov tshwm sim no zoo ib yam rau qhov tsis yog -rotating txiv ntseej nyob rau hauv kev txhais lus raws li ib tug rotating ntsia hlau. Lub hauv paus tsav tsheb thawb cov khoom siv rau pem hauv ntej yog los ntawm kev ua haujlwm ntawm cov hniav helical rotating, uas ua rau lub zog nce mus thiab rau pem hauv ntej ntawm cov khoom raws li tangential trajectory txheeb ze rau cov hniav nto.
Txhawm rau kom ntseeg tau tias lub helical ncej tseem nyob rau hauv qhov muaj txiaj ntsig zoo ntawm qhov nro, lub tshuab tsav thiab qhov chaw nres nkoj tawm feem ntau yog nyob rau tib qhov kawg ntawm lub conveyor, thaum lub chaw noj mov nyob ze li sai tau mus rau tus Tsov tus tw kawg ntawm sab nraud. Lub rotating helical hniav qhia cov khoom los ntawm kev thawb nws mus rau pem hauv ntej; cov rog tiv thaiv cov khoom los ntawm kev sib hloov hauv kev sib koom ua ke nrog cov hniav yog cov khoom siv qhov hnyav thiab kev sib txhuam tsis sib haum los ntawm cov khoom siv conveyor. Nyob ntawm seb cov khoom siv tshwj xeeb raug xa mus, cov hniav helical tuaj yeem muaj ntau yam kev teeb tsa saum npoo, xws li khoom-nto, ribbon- hom, lossis paddle- hom tsim. Ntawm qhov kawg ntawm qhov kawg ntawm lub helical ncej- nyob rau hauv cov kev taw qhia ntawm cov khoom ntws- cov ntsia hlau conveyor yog nruab nrog ib tug thrust bearing los nqus cov axial tshuaj tiv thaiv quab yuam exerted los ntawm cov khoom raws li cov ntsia hlau; rau conveyors ntawm qhov ntev ntev, nruab nrab hanger bearings yuav tsum tau muab ntsia.
