There are various materials which are potential sources for biomass pelets making.Take oil palm wastes as an instance. In oil palm industry, when the fresh palm fruits are harvested, a large quantity of wastes are left, which include empty fruit bunch (EFB), palm kernel shell (PKS), oil palm frond (OPF), oil palm trunk (OPT) and oil palm mesocarp fiber (OPMF). In traditional, some of these wastes are used as organic fertilizer, some are burned for heating, and some are just left.However, these methods are not the most economical solutions.In fact, most of these wastes from oil palm can be properly utilized. The processing method commonly used is making them into pellets or briquettes and then they can serve as fuel. Thus the added value of oil palm wastes is produced.

Oil palm fiber pellet machine is a pelletizing equipment for processing palm tree waste and palm oil factory waste such as pam fibers, palm nut shell, palm kernel shell, empty fruit bunch, palm leaf, etc.

The palm fiber pellet making process is the same as other biomasses, which includes: Drying, crushing, pelletizing, cooling, and packing.

Palm fiber drying and crushing:
The drying and crushing of palm pellet fiber is different from other biomasses because of its nature. Those manufacturers who have no experience in palm pellets making are not able to suggest the most suitable drying and crushing equipments for palm fibers! Only those who have made palm pellets are able to supply the best equipments. See our palm fiber pellet mill plants abroad for reference.

Palm fiber pellet making
The crushed palm fiber powder that contains proper moisture will be fed into the pellet mill and pressed into solid palm fiber pellets with high density.

Palm fiber pellets cooling and packing
The pellets just come out from the pellet mill are hot, so they must be cooled first. Then they can be packed in small or large bags as needed.

1.Empty Fruit Bunches (EFBs)
In contrast to palm kernel shells and fibers, empty fruit bunches can not only be burned, but can also be shipped directly back to the palm garden for fertilizer use.

2.Palm Kernel Shell (PKS)
In traditional waste treatment methods, the pressed fibers and shells of palm mills are often used as fuel for steam boilers. After being processed into granules, it has a higher calorific value and is more environmentally friendly. These two solid fuels alone can generate enough energy to meet the consumption needs of palm oil mills.

Generally, the palm fiber pellets production is in large scale. The ring die palm fiber pellet machine is the most suitable machine for compressing the high density palm fiber. Adopt high-precision gear driving, the output is improved by about 20% compared with the belt drive one. Imported high-quality bearings and oil seal are adopted to ensure efficient, stable and low-noise operation.

The mixed or tempered pulverized palm fiber/palm shell material passes through the chute through the compression mold cover, and is uniformly fed into the two pressing areas in the palm kernel cake(PKC) pellet machine ring die by gravity, centrifugal force generated by the rotation of the ring die, and the action of the feeding scraper.

Under the strong extrusion of the palm fiber pellet machine rollers, the material is gradually compacted and extruded into the die hole of the ring die to form. Since the extrusion of the material between the die rollers is continuous, the formed material continuously emerges from the die hole. The column is discharged, and then a cutter is cut into the required length of particles, and then enters the next palm pellet production line process.

• High heating efficiency:

The oil palm fiber pellets can combust thoroughly in the boiler and only 5% of ash will be remained.

• Low moisture content:

The moisture of palm fiber pellets is just about 8-12% or even lower, which is much less than shredded palm fiber (50-60%). As a result palm fiber pellets can save a lot of transportation cost and the combustion ratio is greatly increased.

• Wide applications:

They can be used for house heating, cooking and BBQ; they can be used for industrial boiler or other heating appliances; also used in power plants to replace coal.

• Palm fiber pellets do not release smoke or harmful gases:

They are quite friendly to the environment.

• Easy to handle and store:

Compared to raw palm fiber, palm fiber pellets have more compact volume, which makes them more convenient to store or transport. As a result, the transportation cost is also greatly cut.
