Sawdust Pellet Mill

Sawdust is got from the sawmill or crushed from wood logs, tree branches, or wasted wood by sawdust-making machine and wood crusher. It is an ideal material to make wood pellets because wood sawdust has a high calorific value. Usually, the size of sawdust is around 5mm, the size can meet the requirement of pellet press machines on raw material. So when investing in a sawdust pellet project, only need to consider the capacity of the project and moisture of sawdust. If the moisture of sawdust is >15% need a drying machine to reduce moisture, if moisture is 12-15% it can make pellets by pellet press machine directly. The capacity of the project decides which model pellet press machine need to use and how many set needed in the project.
Turn sawdust into wood pellets can increase the bulk density, due to compression under 80 Celsius the hardness of the pellets is high, and when burning the wood pellets there is very little pollution. The ash content, sulfur, and smoke emission can comply with European standards.
Our vertical ring dies pellet press machine is efficient on produce wood pellets from sawdust, it is easy operation and maintenance.
Use our vertical pellet press machine can press sawdust into 6mm, 8mm, or 10mm diameter pellets, the length of pellets is 2-5mm adjustable, due to the high compression during pelletizing, the sawdust pellets bulk density is as high as >650Kg/m³, the moisture of wood sawdust pellets is 7-9% and the calorific value is around 4000-4500kcl, which is very good biomass fuel for home heating, boiler, furnace, power plants, the straw pellets also can be used for animal bedding.

Advantages of our sawdust pellet mill

• When feed sawdust into a sawdust pellet making machine, sawdust can drop into pelletizing chamber directly from the top, so a vertical type pellet making machine has advantages on feeding sawdust.

• When sawdust feed in the pelletizing chamber, vertical ring die pellet press machine is rollers running while the ring die is stable, then there is the centrifugal force generated by the rotating rollers, with this centrifugal force rollers are easier to press sawdust into holes of ring die.

• The compression ratio of the ring die is important to make pellets, if the compression ratio of the ring die is not suitable for raw material, it can not make good quality pellets. We have experience in sawdust pellet making, we know what is the best compression ratio to make 6mm, 8mm, and 10mm diameter from different kinds of wood sawdust.

• Our sawdust pellet press machine uses our self-developed gearbox, the gears are specially designed to make pellets according to the strength and pressure needed for pelletizing, so the gears inside the gearbox are stronger, during pelletizing the gears can not break because of high strength pressure. The lifetime of our gearbox is much more longer compared with another vertical pellet mill with the common sued industrial gearbox.

• With a 132kw motor, our MKLH560 model vertical ring dies pellet press machine can produce 1.5-2t/h wood pellets.

• The final pellets are very good fuel for home heating, boiler, and furnace, power plants, also can be used for animal bedding.

• Our vertical ring dies pellet press machine is equipped with oil to recycle pump and oil cooling fan, to recycle and cooling the oil inside the gearbox, thus improving the stability of the pellet machine during operation.

• Our vertical ring dies pellet press machine is equipped with automatic grease to inject the pump, it can inject grease to the bearing of the main shaft and rollers automatically at a certain time with a certain quantity of grease, thus protecting the bearings. Cause of the automatic working, it can save labor on the maintenance.

• The ring die of our vertical ring die sawdust pellet press machine is double layer, which means during using when the holes on one layer worn out, you can turn the ring die to use another side, which greatly extends the lifetime of the ring dies. Our ring die is made of high-wearing resisting alloy steel, with heat treatment and quenches technical, the hardness and ring die are excellent.
