Lub hau ntsia hlau yog qhov tseem ceeb ntawm cov ntsia hlau conveyor, thiab nws yog siv los xa cov khoom siv compressible nrog cov viscosity siab. Thaum lub sijhawm ua haujlwm no, kev ua haujlwm ntawm nplawm thiab sib tov yog ua tiav ib txhij. Cov neeg siv uas feem ntau siv cov ntsia hlau hniav muaj teeb meem txog sab laug thiab sab xis ntawm cov hniav. Qhov teeb meem ntawm kev sib hloov, yuav ua li cas txiav txim rau sab laug thiab txoj cai kev sib hloov ntawm helical hniav yog dab tsi ntau tus neeg mob siab rau. Cia wb mus saib ua ke:
Cov khoom siv kauv hniav tau muab faib ua sab laug thiab sab xis, yog li nws yuav tsum ua kom muaj qhov sib txawv thaum lub sijhawm teeb tsa thiab siv kom tsis txhob muaj kev teeb tsa thiab siv qhov yuam kev, uas yuav ua rau cov cuab yeej tsis ua haujlwm thiab cuam tshuam rau lub neej kev pabcuam.
Kauv hniav tuaj yeem muab faib ua sab laug thiab sab xis. Qhov kev sib hloov yog hais txog kev sib hloov. Feem ntau, cov kauv hniav feem ntau yog sab xis, ib yam li cov ntsia hlau peb siv feem ntau buckled. Thaum peb yuav cov hniav, peb yuav tsum piav qhia txog kev sib hloov ua ntej. Yog tias koj lub tshuab tau siv txoj cai tig, ib qho ntawm cov txiaj ntsig tau tawg. Yog tias koj yuav kev sib hloov sab laug, koj siv tsis tau. Yog tias tsis muaj kev sib hloov sab laug ntawm lub cuab yeej, nws raug nquahu kom siv txoj kev sib hloov sab xis. Feem ntau ntawm lawv, tab sis thaum koj yuav ib sab laug, nws yuav tsis cuam tshuam rau kev siv. Koj tsuas yog yuav tsum tau hloov cov kev taw qhia ntawm lub cev muaj zog.
Muaj ib txoj hauv kev yooj yim kom paub qhov txawv ntawm sab laug thiab txoj cai kev sib hloov ntawm helical hniav, uas yog taw tes rau qhov pib kawg ntawm helical hniav vertically thiab taug kev nyob ib ncig ntawm cov kev taw qhia ntawm kev sib hloov ntawm cov hniav. Yog hais tias nws yog clockwise, nws yog ib tug sinusoidal helical hniav. Yog hais tias nws yog counterclockwise, nws yog ib tug laug-tes helical hniav.
