How to handle the problems in running pellet machine

If the pellet machine failed to boot, you need to check the following points.

1. Whether the power supply is normal connected.
2. Whether the shearing pin is break down.
3. Whether the overtravel-limit switch is in place.
4. Whether the gateway of pellet machine is in place.

If the electricity power is unstable, the following factors and steps should be considered.

1. The space between compression roller and ring die is unsuitable adjusted.
2. Riving knife was badly worn, the material is asymmetrically distributed.
3. Semi-finished products or recycled material contains powder too thick (caused by damaged classifying screen).
4. Raw material, add fluid and steam were not fully mixed.
5. Transmission belt is not of reasonable tightness.

Correct operation of block grease when refuel the pellet machine

What is the correct operation of block grease when refuel the pellet machine, and how to solve the problems?

When refueling pellet machine, first shut the gas, then move block grease.
1. It is unavoidable forgetting to shut down the gas when moving block grease. In this circumstance it will be hard to move, do not move recklessly, shut the gas first.
2. If it was still hard to move after turning off the gas, please remove the inside hexagonal bolt to slide the block greases apart. Then put the two O shape rings correctly again in the middle of the block greases.
3. when the block greases is not linked to the oil line due to high pressure, the block greases will be cling. Just remove the inside hexagonal bolt.

Unusual sound and great vibration of pellet machine working

Pellet machine is working with unusual sound and great vibration. The following factors should be considered as main reasons causing it.

1. The raw material conveying is unstable, and feeding speed should be adjusted.
2. Worn deflection scraper caused uneven feeding, you should change new scraper.
3. Ring die and compression roller of the pellet machine are not all newly installed, it is better to collocate a new ring die with new roller.
4. The space between ring die and compression roller is discordant with the size of raw material. The space is need adjusting.
5. It may be caused by using of both old and new compression rollers, or worn and damaged compression rollers.
6. The formula of raw material is difficult to granulate, the formula should be modified.
7. It may be caused by insufficient steam supply or unstable pressure. Check the steam piping and the system pressure and pressure reducing valve.
8. Granulating granary was filled in sundries, remove sundries in granulating granary.
9. Worn or damaged main shaft bearing needs to change.
