Pellet formation directly affects production efficiency and product quality. Many users face issues like excessive powder, poor formation, or rough surfaces when using pellet mills. Most of these problems aren't machines faults—they're caused by uneven raw material moisture, improper operation, or mismatched dies. Below are 3 common issues and simple solutions:
Half the pellets form, half are powder—Is it an machines issue? It's mostly due to uneven raw material moisture or unstable feeding speed. Easy fix: Check if the feeding system is blocked to ensure smooth material flow; standardize moisture content—avoid some raw materials being too dry and others too wet, which hurts bonding.
New die installed, but pellets still won't form? New dies need preheating and running-in—this key step is often overlooked. Run the machine empty for 10-15 minutes, or use low-pressure material for breaking-in. Let the die and roller fit perfectly before normal production—formation will improve significantly.
Pellets are rough and easy to crack—Is it a formula issue?It may be due to low lignin content in raw materials, which reduces bonding. Add a proper ratio of high-fiber materials or adjust the raw material mix to enhance adhesion—pellets will be smoother and less likely to crack.
