A pellet machine (also known as a pelletiser) is used to produce pellets. The pellets are usually  produced from wood, straw or sawdust and are 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-1000 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.

Pellet making machine Wiesenfield WIE-PM-1000 – assembly of the device

Once you have unpacked your pellet machine, follow the steps below:

1. Attach the wheels of the machine using M8X16 bolts and Ø8 mm washers.
2. Attach the net to the hopper.
3. Place the hopper on the machine casing and screw it on.
4. Screw the chute on as well.
5. Complete the electrical connection. WARNING: Remember that the connection should be made by a qualified person in accordance with the diagram in the manual!

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

1. Place the pelletiser 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 on the rating plate.
3. Check that all screws and bolts are tight.
4. Use the supplied grease gun to inject the bearing grease. Insert the tip of the grease gun into the grease injection hole.
5. Make sure to grease the bearings with grease intended for this purpose.
6. Repeat this operation after every 8 hours of operation of the pellet machine.
7. Adjust the rollers to ensure free movement of the die.
8. 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 will 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 pelletiser 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-1000 pellet machine – operating guide

Once you have the unit ready for 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). Proceed as follows in sequence:

1. Prepare the mixture for pellet making – the maximum length of raw material should be about 5 mm.
2. Connect the pelletiser 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 are done, switch the machine off with the OFF button and unplug it from the power supply.
7. Remember not to stop the machine while the pellets are being pressed (except for an emergency stop)! The machine may clog.
8. Clean the machine so that no pellets are left on the rollers or in the die.
9. Bear in mind that the pellets will reach the correct consistency only after they have cooled down.

Servicing the Wiesenfield WIE-PM-1000 step by step
