EMA Extrusion Unstable Feeding
ظاهرة المشكلة
EMA extrusion feeding amount fluctuates ±15%, causing unstable extrusion pressure and product dimensions
تحليل الأسباب
EMA pellets irregular in shape, causing unstable feeding screw fill rate; bridging or voids in the hopper; feeding screw design unsuitable
الحل
1) Use a loss-in-weight feeder to precisely control the feeding amount; 2) Install a vibrator on the hopper to prevent bridging; 3) Pelletize EMA to a uniform particle size of 2-3mm; 4) Change the feeding screw to a dedicated design
الخلاصة الأساسية
Unstable feeding is caused by pellet characteristics; loss-in-weight feeding and anti-bridging are the core
