A pellet machine (also known as a pelletiser) is used to produce pellets. The pellets are usually produced usually from wood, straw or sawdust pressed under high pressure. You can use them as fuel for your pellet furnace or as animal feed. From our article, you will learn how to properly service and operate the Wiesenfield WIE-PM-1500 pellet making machine.

How does a pellet machine work?

A pelletiser converts biomass, such as sawdust, into pellets in an efficient manner. Once the feedstock is poured into the hopper, it is compressed by a die inside the machine. The process takes place at a high pressure and a temperature of 60 to 80°C, which ensures an optimal pellet consistency. Its size depends on the die used. The diameter of its holes translates into the size of the pellets obtained.

4. Also screw on the chute.

How do I prepare the Wiesenfield WIE-PM-1500 for operation?

1. Place the pelletizer in a safe, clean, stable place (away from heat and water) to ensure air flow.
2. Make sure that the power supply to the appliance matches the data given on the rating plate.
3. Check that all screws and bolts are tightened.
4. Inject grease on the main shaft using a grease gun.
5. Dismantle the rollers and remove the bearings.
6. Grease the bearings and assemble the rollers.
7. Remember to lubricate the bearings and rollers with grease intended for this purpose.
8. Repeat this operation every 8 hours of pellet machine operation.
9. Adjust the rollers to ensure free movement of the die.
10. Top up the oil.

How do I grind the die before first use?

Remember to prepare the machine correctly before grinding the die (see above)!

1. To grind a new die you need:
   • 5 kg of sawdust (sawdust or flour),
   • 1,5 l of vegetable oil (can be used or dirty),
   • 5 kg of fine sand (optional).
2. Mix all ingredients in a bucket until a smooth consistency is achieved.
3. Connect the pelletizer to the power source, then switch on using the ON button. The motor should start and the die should begin to rotate.
4. Place the pellet container under the chute.
5. Push the mixture through the die 80-90 times until the pellets meet the quality requirements.

How to start the Wiesenfield WIE-PM-1500 pellet machine – operating guide

Once you have the machine ready to use and the die grinded, you can proceed. Before using it for the first time or after replacing the die, always verify that the direction of rotation of the die is in line with the arrow (sticker on the casing). Follow the following steps in sequence:

1. Prepare the mixture for pellet making – the maximum length of raw material should be about 5 mm.
2. Connect the pelletizer to the power source, then switch on using the ON button. The motor should start and the die should begin to rotate.
3. Place the pellet container under the chute.
4. Pour a small amount of the mixture to be granulated into the hopper. If you throw in too large of a portion at once, the die may clog.
5. Follow the same procedure until the prepared mix has been completely processed.
6. When you have finished working, switch the machine off with the OFF button and unplug it from the power supply.
7. Remember not to stop the machine during pellet pressing (except for emergency stop)! The machine may clog.
8. Clean the machine so that no pellets are left on the rollers or in the die.
9. Be aware that the pellets will only reach the correct consistency once they have cooled down.
