Is the fish pellet machine spraying material due to operator error?

 

 

Many material spraying problems are caused by improper operation-for example, feeding material directly without preheating the machine, or suddenly adding a large amount of material. The material cannot "accommodate" in the barrel and will spray out. Beginners are prone to these pitfalls, but many material spraying problems can be avoided by following the correct operating procedures.

 

Why is material being ejected without preheating?

 

In winter or after the machine has been idle for a long time, the barrel and screw temperatures are very low (e.g., only 10℃). If you add material directly, it will stick to the cold screw and barrel, like ice sticking to your hand, making it impossible to turn or push. Subsequent material will then be ejected from the feed inlet under pressure.
Solution: Preheat the machine before starting – turn on the heating switch to raise the barrel temperature to the set value (e.g., 120℃), and let the screw idle for 5-10 minutes to warm it up. The barrel should feel slightly warm to the touch before starting to feed material.

 

Why doeWhy is the material spraying out due to excessive/uneven feeding?

 

1.Sudden surge of material: When starting the machine, the feeder speed is suddenly increased too much (e.g., from 0 to 50 rpm), causing the material to flood into the barrel, overwhelm the screw, and spray out from the inlet.
Solution: Feeding should be gradual. First, adjust the feeder speed to the lowest setting (e.g., 10-15 rpm). After the material smoothly enters the barrel and is extruded from the die, gradually increase the speed (increase by 5-10 rpm each time) until the required capacity is reached.

 

2. Inconsistent feeding during manual feeding: Without a feeder, material is poured directly into the inlet by hand, resulting in inconsistent amounts. Too much material causes the barrel to pile up and spray out, while too little causes the screw to spin idly.
Solution: Install a simple feeder (even a small one), or use a spoon to feed evenly, ensuring a stable flow of material into the barrel and avoiding inconsistent amounts.

 

Why is material spraying out the next time the machine is restarted if it's not cleaned after shutdown?

 

The barrel and die weren't cleaned after the last production run, and the hardened residual material got stuck inside, like a "stone." The next time the machine is started, the new material can't push the hardened old material, so it sprays out of the feed inlet. Solution: Always "clean the machine" before shutdown-first turn off the feeder and let all the material in the barrel run out. Then add a small amount of dry material (like cornstarch) to the feed inlet and let the screw idle for 5 minutes to carry out any remaining material. Finally, disassemble the die and clean any remaining material from the holes.
