What are the main reasons behind the drop in granulation production at feed mills? According to a recent analysis by Good Feed, there are several key factors that can lead to reduced efficiency in the pelleting process. Here are five common causes:
1. Wear on the ring die surface – Over time, the working area of the ring die can become worn or damaged, which affects the quality and consistency of the pellets being produced.
2. Mold hole spots and nicks – Small imperfections in the die holes can cause uneven pellet formation, leading to lower output and increased machine downtime for maintenance.
3. Incorrect roll gap adjustment – The gap between the rollers must be properly set to ensure effective compression of the material. If it's too wide or too narrow, it can significantly impact granulation performance.
4. Decompression hole granulation – This issue occurs when the pressure inside the pellet mill is not properly maintained, resulting in poor compaction and lower production rates.
5. Severe wear on the pressure roller – As the pressure roller wears down, it loses its ability to apply even pressure, which can lead to inconsistent pellet quality and decreased output.
