Jinsi Kila Pelletizer Inafanya kazi

Mchakato wa Pelletizer wa Strand

Kupoa na Kukata

Mifumo ya strand pelletizer hufanya kazi kwa kubadilisha polima iliyoyeyuka kuwa pellets za silinda. Mchakato huanza na kulisha nyenzo ndani ya kompakt kwa kutumia conveyor ya ukanda. Kasi ya kulisha inaweza kubadilishwa, na kugundua chuma mara nyingi hujumuishwa ili kuzuia uchafuzi. Visu vya kuzunguka ndani ya kompakt hupasua na joto nyenzo, kuimarisha kabla ya kuingia kwenye screw extruder. Extruder huyeyusha polima, na mfumo wa utupu huondoa uchafu. Mara tu polymer imeyeyuka kabisa, inahamia kwenye kichwa cha kufa. Hapa, nyuzi zilizoyeyushwa hukatwa na kupozwa katika a pete ya maji, ambayo huondoa hitaji la utunzaji wa kamba ya mwongozo. Pete ya maji inahakikisha baridi ya haraka na husaidia kudumisha sura ya pellet.
