Preheating Ntaus rau Yas Granulator

Preheating ntawm txoj hlua cab yog qhov tsim nyog rau ob leeg rwb thaiv tsev extrusion thiab sheath Extrusion. Rau rwb thaiv tsev txheej, tshwj xeeb tshaj yog rho txheej txheej txheej, muaj cov hws tsis tau tso cai. Cov tub ntxhais muaj peev xwm ntxuav tau huv ntawm cov dej noo thiab roj stains los ntawm kev kub siab preheating ua ntej extrusion. Rau qhov extrusion ntawm lub ntsej muag tseem ceeb yog kom qhuav cov cable tseem ceeb thiab tiv thaiv kom muaj peev xwm ntawm cov pa hluav taws xob hauv qhov chaw noo (lossis noo noo los ntawm txheej qhwv). Preheating tseem tuaj yeem tiv thaiv cov seem sab hauv lub siab ntawm cov yas thaum lub sij hawm expusion vim yog kev cua txias.
Thaum lub sij hawm yas extrusion txheej txheem, preheating tuaj yeem tshem tawm qhov sib txawv loj tshwm sim los ntawm cov yas ntawm qhov kub thiab txias thiab txias rau cov roj hmab kub thiab txias, yog li ua kom muaj zog tso tawm cov khoom kom zoo thiab ua kom zoo dua qub. Cov khoom siv hluav taws xob hluav taws xob hluav taws xob cov hlau tseem ceeb tau siv rau hauv cov khoom siv hluav taws xob kom txaus siab thiab ua kom muaj peev xwm ua kom muaj peev xwm ua kom muaj zog hauv xaim thiab cov xaim hluav taws xob kom qhuav. Lub preheating kub yog txwv los ntawm xaim tawm ceev thiab feem ntau zoo ib yam li lub taub hau kub.
