Does faulty functioning of the pellet mill for chicken feed cause the feed spraying problem?

 

 

Many material spraying problems are caused by improper human operation-for example, feeding material directly without preheating the machine, or suddenly increasing the feeding speed. The material cannot adapt in the barrel and will spray out. Many beginners are unaware of the correct operating procedures and easily fall into these traps.

 

 

In winter or after the machine has been idle for a long time, the barrel and screw temperatures are very low (like room temperature, such as below 10°C). If you add material directly, it will stick to the cold screw and barrel, like "ice stuck to your hand," preventing it from being pushed forward and causing it to pile up at the feed inlet and spray out. Solution: Preheat the machine before starting – turn on the barrel heating device to raise the barrel temperature to 50-60°C (check with a temperature gauge), and simultaneously let the motor idle for 5 minutes to warm the screw and barrel before slowly feeding material.

 

 

Suddenly increasing the feeder speed too much (e.g., from 20 rpm to 50 rpm) causes the raw material to enter too quickly. The screw in the barrel can't handle the load, causing the material to accumulate below the feed inlet and spray out. Solution: Feeding should be gradual. When starting the machine, first adjust the feeder speed to the lowest setting (e.g., 15 rpm). Once the raw material enters the barrel smoothly and the pellets come out normally, gradually increase the speed (increase by 5 rpm each time) until the required production capacity is reached.

 

 

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

 

 

Start-up: Preheat the barrel → Idle motor → Slow feeding → Gradually increase speed; During production: Maintain a stable feeding speed, avoid sudden increases; Shutdown: Clean raw materials → Clean the barrel → Clean the ring die.
