4. Pub System: Lub tshuab pub noj yog lub luag haujlwm rau kev qhia cov khoom siv rau hauv lub sifter. Nws tuaj yeem yog lub hopper, conveyor, lossis lwm yam txheej txheem tsim los xyuas kom muaj kev ruaj khov thiab tswj cov khoom ntws.
5. Discharge System: Lub kaw lus tso tawm yuav khaws cov khoom sib cais thiab coj mus rau qhov hluav taws xob tsim nyog lossis ntim khoom.
Txoj Cai Ua Haujlwm ntawm Sifter
Lub hauv paus ntsiab lus ua hauj lwm ntawm ib tug sifter txawv nyob ntawm seb nws hom thiab tsim. Txawm li cas los xij, txoj cai dav dav suav nrog kev txav ntawm cov khoom siv los ntawm cov sieves lossis cov ntxaij vab tshaus, uas cais cov khoom raws li lawv qhov loj me.
Hauv vibratory sifters, cov khoom yog pub rau ntawm qhov screen, thiab cov vibrations ua rau cov khoom txav mus rau ntawm qhov screen. Cov khoom loj loj raug tso tawm los ntawm lub qhov hluav taws xob, thaum qhov loj me me dhau los ntawm kev tshuaj ntsuam thiab raug sau.
Nyob rau hauv teb sifters, cov khoom yog pub rau hauv lub cylindrical sieve, thiab rotating motion ua rau cov hais mus raws lub sieve nto. Cov khoom uas loj dua li lub sieve qhib tau tawm, thaum cov khoom me me dhau los.
Centrifugal sifters ua haujlwm los ntawm kev tig lub sieve ntawm kev kub ceev. Lub zog centrifugal thawb cov khoom tawm tsam lub sieve, thiab cov khoom uas loj dua li lub sieve qhib tau tawm.
Air classifiers siv cov cua ntws los cais cov khoom. Cov khoom yog nkag mus rau hauv ib qho airflow, thiab cov khoom yog nqa mus rau pem hauv ntej. Cov khoom loj dua tau yoog sai dua vim lub ntiajteb txawj nqus thiab tau sau, thaum cov khoom zoo dua yog nqa mus ntxiv thiab sib sau ua ke.
Kev siv ntawm Sifters
Sifters nrhiav kev siv dav hauv ntau qhov kev lag luam rau kev sib cais particle thiab kev faib loj. Qee qhov kev siv ntau ntawm sifters suav nrog:
