1.The die hole is blocked when the machine is turned on and no pellets are produced

1. Flat die hole rust

2.The flat die hole is rusty and the smoothness is poor

3.The gap between the die and the roller is too large

1. Remove the residual pellets in the die hole

2. Grind with high oil content powder

3. Adjust the gap to 0.1-0.3 mm

2.The pellets contain too much powder or cannot form pellets

1. The moisture content of the powder is too low

2. The moisture content of the powder is too high

3. The powder contains a large amount of crude fiber

1. Increase moisture content

2. Reduce moisture content

3. Add sticky powder material

3.Output gradually decreases

1. The gap between the die and the roller is too large

2. The moisture content is too low

1. Adjust the gap between the die and roller

2. Increase the moisture content

4.The pellets are hard

1. The moisture content of the powder material is low

1. Increase the moisture content of powder material

5. Pellets become soft

Pellet surface is rough

1.Improper moisture content

2. New die for the first time

1. Reduce or increase moisture content

2. Squeeze with oil-containing materials
