What Is Palm Kernel Shell?


Palm oil industry is quite common in most countries of Southeast Asia and Africa. Palm fruit covered with palm kernel shell is the raw material to produce palm oil. Palm kernel shell also named PKS is the shell of palm fruit (Arecaceae), being separated from palm fruit throng palm oil process.

Value of palm kernel shell pellet and palm briquettes


Before biomass fuel idea enter the market, palmkernel shells are generally be used to make black color palm kernel compost by burying underneath the land for a very long time. However, such great amount of palm kernel shells are not that easily rotten and alkalinity of the soil will be destroyed by the acid substance produced after decay.


With the development of biomass fuel technology, processing palm kernel shells into high caloric RDF (refuse derived fuel) has proved to be a good way. The calorific of pelletized palm kernel shell is about 4200~4900 cal/kg.

Step1 Collecting of Palm Kernel Shell


In 2005,7,599, 000 ha oil palm was harvested in Asia totally and with 146,093,000 tonnes of fresh fruit bunches and 10224000 tonnes of Palm Kernel Shell produced. Most of Palm Kernel Shell can be collected in palm oil factories.


Step2 Shredding of Palm Kernel Shell


Shredding bulky Palm Kernel Shell into smaller particle is a vital step to reduce thespace of storage and produce palm pellets and palm briquettes. Harden Company specialized Palm Kernel Shell shredder two shaft shredder and hydraulic shredder can process bulky Palm Kernel Shell into 10-20mm particle.

Step3 Drying of Palm Kernel Shell


Palm Kernel Shell contains high water content, to produce high caloric RDF for boiler,removing water with a dryer is a necessary step.


Step4 Pelletizing of Palm Kernel Shell


Palm fiber pellets or briquettes are compressed palm fiber. They can be made by pelletmill and briquette machine.
