Failure phenomenon	cause of issue	elimination method
1	The material can enter the pressing room normally, but no pellets can be pressed	1. Blockage of mold hole 2. Too much or too little moisture in the material 3. The pressure roller gap is too large 4. The feeding scraper is damaged 5. The roller bearing is damaged	1. Punch through the die hole with the corresponding drill 2. Correctly adjust the moisture 3. Adjust the gap between the pressure rollers 4. Replace the feeding scraper 5. Replace the roller bearing
2	No raw material enters the pressing room	1. Material accumulation in the storage hopper 2． The feeding auger is blocked	1. Break the arch 2. Draw out the dragon to clean up
3	Safety pin broken	Suppress the entry of hard foreign objects in the room	Remove foreign objects and replace safety pins
4	The host can't start	1. Suppress indoor material accumulation but not cleared 2. The circuit is faulty	1. Clear accumulated materials 2. Eliminate circuit faults

6	Noise and vibration	1. Bearing wear failure 2. Serious wear of ring die and pressure roller 3. The gap between the ring die and the pressure roller is too small 4. There is a foreign body in the conditioner or auger 5. There is a small hard foreign body pressed into the mold hole	1. Replace the bearing 2. Replace the ring mold and pressure roller 3. Adjust the gap 4. Draw out the auger shaft or quenched and tempered shaft for cleaning 5. Remove foreign objects in the ring mold
7	The output is not up to the requirement	1. The pellets are not high 2. There is a problem with the raw material ratio 3. Ring die hole blocked 4. Wear of ring die and pressure roller 5. The current is not up to the rated value	1. Reasonably adjust the moisture content of raw materials 2. Adjust the ratio of raw materials 3. Clean up foreign objects in the ring mold 4. Replace ring die and pressure roller 5. Increase the speed of the feed auger and increase the feed amount.
8	Oil spill	Damaged oil seal	Replace the oil seal
