Yog vim li cas: Qhov teeb meem no feem ntau cov khoom pellet tawm hauv lub tshuab yog tsim, thaum lub cutter txoj hauj lwm yog kho nyob deb ntawm qhov chaw thiab cov riam yog blunt, cov hais los ntawm lub tuag qhov extrusion yog txiav los ntawm riam kov los yog tsim kua muag es tsis txhob txiav. tawm, ces qee qhov ntawm cov khoom pellet nkhaus mus rau ib sab thiab sab nraud qhia ntau qhov tawg. Cov khoom siv granular zoo li no nyob rau hauv qhov txias txias rau hauv cov txheej txheem txias lossis kev thauj mus los, feem ntau los ntawm cov kab nrib pleb no yuav tawg, ua rau cov khoom siv granular hmoov ntau dhau.
Kev txhim kho: 1, Ua kom cov compression piv ntawm cov pwm, thiaj li ua rau kom qhov ceev thiab hardness tus nqi ntawm cov khoom pellet.
