7、Cause and solutions of material could enter the pressing room normally, but could not make pellet.
Cause:
1. Die hole is blocked
2. Moisture content is too high or too low
3. The interval between die and roller is too large
4. Feeder scraper is broken
Solution:
1.Get through the die hole
2.Adjust the steam volume correctly
3.Adjust the die –roller interval
4.Change feed scrape

8、Cause and solutions of main machine cannot get started.
Cause:
1. Accumulated material in the pressing room did not get cleared
2. Breakdown in the electric circuit
Solution:
1.Clear the accumulated material
2.Get rid of the circuit breakdown

9、 Cause and solutions of noise, violent vibration.
Cause:
1. Moisture content inappropriate
2. The die and roller wearing badly
3. Die-roller interval too small
4. Foreign matter in conditioner of screw feeder
5. Small hard foreign matter was pressed into die hole
Solution:
1.Change bearing
2.Change die and press roller
3.Adjust interval
4.Pull out screw feeder axle or conditioner axle to clear
5.Clear the foreign matter in the die

10、Cause and solutions of low capacity.
Cause:
1. Inappropriate moisture content
2. Wrong material prescription
3. Inappropriate powder material fineness
4. Granular material too hard
5. Electric current does not reach the specified value
Solution:
1.Adjust steam volume correctly
2.Adjust the material prescription
3.Improve powder material quality
4.Change die or reduce the effective length of die hole
5.Increase the rotating speed of screw feeder, increase material and steam inlet volume.
