Lub cev tseem ceeb ntawm tus pin-tsav ntsia hlau yog tus qauv ntsia hlau. Pins tuaj yeem muab tso rau hauv qhov grooves ntawm melting los yog metering seem ntawm cov ntsia hlau, los yog nyob rau ntawm lub cylindrical du nto yam tsis muaj grooves ntawm qhov kawg ntawm metering seem. Pins tau teem rau hauv ib qho qauv tshwj xeeb, nrog qhov sib txawv ntawm qhov ceev thiab tus lej. Cylindrical pins yog tsim los ntawm kev sib sau ua ke rau hauv qhov hauv cov ntsia hlau; square lossis pob zeb diamond- zoo li tus pins yog tsim los ntawm milling ncaj qha rau ntawm lub hau. Yog tias cov pins no tau muab tso rau hauv thaj chaw melting, lawv tuaj yeem tawg lub txaj khoom, cuam tshuam ob -theem ntws, sib tov cov khoom thiab cov theem ua kua ua ke, ua rau thaj chaw sib cuag ntawm cov khoom tawg thiab cov khoom tawg, thiab txhawb kev yaj. Yog tias cov pins tau muab tso rau hauv qhov chaw xa khoom yaj, lawv lub luag haujlwm tseem ceeb yog faib cov khoom ntws, nce qhov sib txuas, hloov cov kev taw qhia ntawm cov khoom ntws, thiab rov kho cov dej ntws. Ntau qhov kev sib txawv thiab kev sib koom ua ke hloov pauv kev coj ua, homogenizing cov yaj muaj pes tsawg leeg thiab kub.
Cov khoom sib xyaw yog ib qho kev sib txuas sab hauv uas nyob rau hauv qhov kawg ntawm homogenization seem ntawm tus qauv ntsia hlau, nrog ib txoj kab uas hla sab nraud sib npaug rau sab nraud ntawm cov ntsia hlau. Cov grooves tau muab faib ua ob peb pawg, nrog rau txhua pab pawg tsim cov khoom sib txuam. Cov khoom yog muab faib los ntawm cov grooves, converges nyob rau hauv confluence cheeb tsam, thiab ces muab faib thiab converges dua, zoo ib yam li tus pin - hom ntsia hlau. Cov yam ntxwv ntawm cov ntsia hlau sib cais yog tias, ntxiv rau qhov tseem ceeb ntawm cov ntsia hlau xov (hu ua lub ntsiab ntsia hlau), ib qho xov ntxiv (hu ua auxiliary xov) ntxiv rau hauv seem melting. Nws txoj kab uas hla sab nraud yog me ntsis me dua ntawm cov xov tseem ceeb ntawm txoj kab uas hla, thiab cov hlau lead ntawm lub ntsiab thiab cov xov tseem ceeb sib txawv. Cov xov auxiliary pib thaum kawg ntawm ntu pub mis (thiab txuas mus rau ntu pub mis), thiab tom qab dhau los ntawm ob peb lub xov, maj mam sib tshuam nrog cov xov tseem ceeb ntawm seem homogenization. Nyob rau hauv hom ntawm cov ntsia hlau no, qhov zawj qhov tob thiab xov hlau maj mam hloov ntawm ntu pub rau qhov kawg ntawm homogenization; uas yog, cov xov hlau maj mam nqaim los ntawm qhov dav mus rau qhov nqaim, thiab qhov zawj qhov tob maj mam txav los ntawm qhov tob mus rau qhov ntiav, tso cai rau cov khoom siv ntau tshaj plaws.
