Cov chav sib xyaw ua ke muaj feem ntau ntawm cov nruas sib xyaw thiab nws cov khoom txhawb nqa. Lub nruas sib tov ua lub thawv rau pob zeb; Raws li nws rotates, cov pob zeb txav mus raws txoj kev helical ntawm cov hniav sab hauv, tab tom nqa thiab tumbling, uas ua kom muaj kev sib xyaw ua ke. Thaum lub sij hawm thauj khoom thiab thauj, lub nruas tig mus rau pem hauv ntej, txav cov pob zeb sab hauv nrog cov hniav; Thaum tso tawm, lub nruas thim rov qab, txav cov pob zeb tawm sab nraud rau kev tshem tawm.
Cov hniav yog cov khoom tseem ceeb ntawm cov khoom sib xyaw; kev puas tsuaj los yog hnav hnyav tuaj yeem ua rau kev sib xyaw ua ke tsis sib xws. Tsis tas li ntawd, cov hniav tsis zoo tuaj yeem ua rau muaj kev sib cais.
Ntxuav System
Lub luag haujlwm tseem ceeb ntawm kev ntxuav yog ntxuav lub nruas sib xyaw; nws kuj yog qee zaum siv los sib tov cov khoom qhuav hauv lub nruas thaum thauj. Lub kaw lus kuj tseem pab ua kom txias ntawm hydraulic system.
Sealing System
Lub kaw lus kaw tag nrho siv cov cuab yeej sib txuas sib txuas los kaw qhov chaw thau khoom thiab tawm qhov qhib ntawm lub tsheb sib tov. Qhov no daws ntau yam teeb meem cuam tshuam nrog cov tsheb thauj khoom ib txwm muaj, xws li ya raws evaporation, mortar stratification, pob zeb spillage, thiab kev nyab xeeb thaum ua haujlwm.
