Thaum cuam tshuam nrog kev poob qis, muaj ntau yam khoom siv thiab cov txheej txheem cuam tshuam rau lub sijhawm poob, ib qho ntawm feem ntau ua rau paddle dryer downtime yog blockage ntawm cyclones, chamber outlets, conveyor kab thiab cov khoom zoo sib xws; blockages yog ob lub ntsiab ua rau: mechanical teeb meem thiab ya raws. Cov teeb meem kev siv tshuab - seb puas yog txuas los yog txo qis - yooj yim dua rau kev ya raws. Cov teeb meem no tau daws nrog kev siv cov cuab yeej siv tshuab xws li pneumatic hammers, choj crushers lossis nce qhov hluav taws xob loj.
More difficult problems include moisture and condensation. By definition, the air inside a drying process vessel—whether it's a chamber, cyclone, or baghouse—is moist and warm, while the temperature outside the vessel is cooler. Condensation can occur if the inner surface of the container is allowed to cool below the dew point of the humid air.
Rau cov txheej txheem nrog lub tshuab ziab khaub ncaws kub ntawm 160 ° -180 ° F, qhov dej lwg tuaj yeem nyob rau hauv thaj tsam ntawm 120 ° -130 ° F. Yog tias lub nkoj nyob ntawm 80 ° F, muaj qhov kub txaus sib txawv los ua kom sov thiab poob. condensation, ua rau cov khoom ntsaws los yog choj. Cov teeb meem no feem ntau raug tshem tawm yog tias lub nkoj yog insulated thiab tsho los yog cua sov.
Cyclone tip lossis tseem ceeb tivthaiv rau cov khoom export. Nyob rau hauv lub cua daj cua dub, qhov kev sib hloov ntawm huab cua yog siab. Hloov pauv, vim huab cua nrawm nrawm, huab cua siab tsawg. Piv txwv li, nyob rau hauv ib tug high efficiency cyclone nrog ib tug 6 nti dej kem siab sib txawv ntawm cov cua inlet thiab qhov hluav taws xob, qhov zoo li qub siab nyob rau hauv lub ntsis tej zaum yuav yog -20 nti dej kem. Qhov siab qis no zoo ib yam li kev txav dej hiav txwv los ntawm hiav txwv mus rau 1,400 feet saum hiav txwv. Qhov no tsis tshua muaj siab nyob rau hauv cheeb tsam ntawm lub cyclone tip ua rau pos huab los yog condensation nyob rau hauv cov huab cua.
