Small pellet feed machines may sometimes have varying degrees of surface defects during operation. What are the reasons for this? Let's take a brief look at small pellet feed machine manufacturers together!

1. The feed pellets are bent and have many cracks on one side. The main reason for this situation is that feed particles leave the mold. In response to this situation, we can increase the compression ratio of the ring mold, thereby increasing the density, hardness, and strength of the feed particles.

2. Horizontal cracks appear that run horizontally through the entire feed pellet. Mainly during the granulation of fluffy feed containing a large amount of fiber, due to the presence of fibers longer than the pore size, when the feed particles are extruded, the expansion effect of the fibers causes cracks in the cross-section of the feed particles. Improve the fineness of crushing so that the longer fibers do not exceed one-third of the particle size.

3. Longitudinal cracks appear in feed pellets. The feed formula contains fluffy and slightly elastic raw materials that absorb water and expand after conditioning. After being compressed and granulated by a ring mold, they will bounce apart due to the effect of moisture and the elasticity of the raw materials themselves. You can try adjusting the feed formula, extending the conditioning time, or using multi-layer modulators.
