• Cov cuab yeej tsis saib xyuas kev saib xyuas:Yog tias tsis muaj kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua, cov teeb meem zoo li tuag lub taub hau thaiv thiab cov hniav hnav yuav tsis pom, ua rau muaj teeb meem tsis tu ncua.

III. Kev daws rau Puffing Puffing Moulding nyob rau hauv Aquatic feed pellet mills

1. Optimize Raw Material Processing thiab Tswj Raw Material Parameters

• Raw Material Screening:Xyuas kom meej qhov loj me me (20-40 mesh) los ntawm kev tshuaj ntsuam thiab crushing raw khoom kom tshem tawm cov khoom loj thiab impurities uas yuav cuam tshuam rau molding.
• Moisture Content Adjustment:Ntsuas thiab kho cov ntsiab lus noo noo mus rau qhov zoo tshaj plaws (12% -15%). Yog tias cov dej noo ntau dhau, cov ntaub ntawv qhuav; yog tias tsawg dhau, txau dej thiab do kom sib npaug.
• Siv Vertical Mixing Mills:Txhawm rau kom muaj kev sib xyaw ua ke thiab zam qhov sib txawv hauv cheeb tsam hauv cov dej noo lossis qhov loj me, siv lub tshuab ntsug ntsug.
• Ntxiv Binders:Siv tus nqi tsim nyog ntawm binder hauv cov khoom siv raw los txhim kho plasticity thiab txo qhov tawg thiab adhesion.

2. Tshawb xyuas Tuag Lub Taub Hau thiab Cutter rau Ib txwm Dej Pub Pellet Ua Tshuab Ua Haujlwm

• Regular Die Head Cleaning:Ntxuav lub taub hau qhov taub tom qab txhua qhov kev tsim tawm los tiv thaiv cov khoom thaiv cov khoom thiab xyuas kom meej qhov loj me me.
• Die Head Wear Inspection:Txheeb xyuas qhov hnav tsis sib xws hauv lub taub hau tuag, thiab hloov nws yog tias tsim nyog los xyuas kom meej qhov ntau thiab tsawg.
• Cutter Hniav Maintenance:Tshawb xyuas thiab hloov cov hniav txiav yog tias hnav. Kho cov hniav ceev kom phim cov zis ceev kom zoo ib yam txiav thiab tsis txhob tawg.
• Die Head Temperature Regulation:Xyuas kom tus tuag lub taub hau cua sov coil ua haujlwm kom zoo thiab tswj xyuas qhov kub thiab txias kom tsis txhob muaj cua sov hauv cheeb tsam.

3. Stabilize Aquatic feed pellet extruder Parameters thiab optimize txheej txheem chaw
