Palm Shell: The Future of Biomass Energy
Palm Kernel Shell (PKS) is the hard, shell-like byproduct remaining after palm oil extraction. As global demand for renewable energy surges, PKS has emerged as one of the most efficient and sustainable biomass fuel sources — with a market projected to reach USD 1.01 billion by 2034, growing at a CAGR of 9.1%.
High Calorific Value
PKS delivers 4,000–4,500 kcal/kg (18–20 MJ/kg), significantly outperforming rice husk and matching premium wood pellets. Low moisture content below 8% ensures complete, efficient combustion in industrial boilers.
Carbon Neutral & Sustainable
As a plant-based byproduct, PKS absorbs CO₂ during palm tree growth. Combustion releases only the carbon previously captured, making it carbon neutral. PKS requires no deforestation — it is a natural waste product from palm oil milling.
Abundant Global Supply
Indonesia and Malaysia alone produce over 22 million metric tons of PKS annually. Japan imported 4.5+ million tons in 2024, with demand growing 15–21% year-over-year. Southeast Asia's 1,200+ active palm oil mills ensure continuous, scalable supply.
Palm Waste Feedstock for Pellet Production
A complete palm shell pellet production line can process multiple types of palm oil industry waste. Each raw material has unique characteristics that influence the preprocessing requirements and final pellet quality.
Complete Palm Shell Pellet Production Process
The palm kernel shell pellet production line transforms raw palm waste into uniform, high-density fuel pellets through seven precisely engineered stages. Hover over each step to view detailed information and equipment specifications.
Palm Shell Crushing & Size Reduction
Raw palm kernel shells are fed into a heavy-duty hammer mill or wood chipper for initial size reduction. For EFB and palm fiber, a drum-type shredder first breaks long fibers into 5–10cm lengths, followed by a specialized palm chopping machine that reduces material to fine powder. The crushing section uses negative-pressure pneumatic conveying to minimize dust pollution and maximize throughput.

Impurity Removal & Screening
Crushed palm material passes through a rotary screen or primary cleaning sieve to remove large debris, stones, metal contaminants, and other impurities. Magnetic separators protect downstream equipment from damage. This stage achieves 95–98% impurity removal, ensuring smooth operation of pellet mills and consistent pellet quality.

Moisture Reduction to Optimal Level
Palm shell raw material often contains 40–65% moisture. A triple-pass rotary drum dryer, powered by an industrial hot blast stove, reduces moisture content to 12–15% — the optimal range for pelletizing. The drying system achieves 90% thermal efficiency with ±1% moisture uniformity. For PKS with naturally low moisture (8–12%), this step may be simplified or bypassed.

Particle Size Reduction for Pelletizing
Dried palm material is ground in a high-speed hammer mill to achieve uniform particle size of 3–6mm. The water-drop type hammer mill delivers 90%+ particle uniformity with 15–20% lower energy consumption. Adjustable screen sizes (1–30mm) provide flexibility for different pellet specifications and raw material conditions.

High-Pressure Pellet Formation
The heart of the production line. Rongda's RD series vertical ring die pellet mill compresses prepared palm material into dense cylindrical pellets of 6–12mm diameter. Under strong extrusion between rollers and ring die, natural lignin in the palm shell acts as a binder, eliminating the need for chemical additives. The gear-driven system improves output by 20% compared to belt-driven alternatives. Capacity ranges from 0.5 T/H (RD-350MX) to 5.5 T/H (RD-915MX).

Temperature & Moisture Reduction
Hot pellets exiting the pellet mill (approximately 80–90°C) are cooled in a counterflow cooler to within 5°C of ambient temperature. This process simultaneously reduces pellet moisture to 8–10% and increases pellet hardness, minimizing breakage during handling and transport. The SKLN series cooler handles 5–30 T/H with less than 0.8% breakage rate.

Automated Weighing & Bagging
Cooled pellets are screened to remove fines (which are recycled back into the process), then automatically weighed and packaged. Small bag packaging scales handle 20–50kg bags, while ton-bag scales package 500–2,000kg bulk bags. Rongda's packaging equipment achieves ±0.1% accuracy with throughput up to 1,200 units/hour. Automated palletizing systems are available for high-volume operations.

Palm Shell Pellet Applications
PKS pellets serve as a versatile renewable energy source across multiple industries, from large-scale power generation to residential heating, replacing fossil fuels with a carbon-neutral alternative.
Biomass Power Plants
Primary fuel for biomass-based combined heat and power (CHP) plants. Over 70 power plants in Japan alone use PKS for base-load electricity generation under the FIT program.
Industrial Boilers
Direct combustion in industrial steam boilers for palm oil refineries, cement factories, textile mills, and chemical plants. Combustion efficiency above 85% in modern biomass boilers.
Residential & Commercial Heating
Clean-burning fuel for home heating stoves, commercial heating systems, and district heating networks. Low smoke and particulate emissions make it suitable for urban environments.
Cement & Steel Industry
Alternative fuel for cement kilns and foundries, reducing carbon emissions while maintaining process temperatures. Co-firing with coal achieves significant CO₂ reduction targets.
Activated Carbon Production
PKS is an excellent precursor for activated carbon used in water filtration and air purification systems. The high carbon content and porous structure make it ideal for this application.
Co-firing with Coal
Blending PKS pellets with coal in existing thermal power plants reduces CO₂ emissions by approximately 1.7 metric tons per metric ton of coal displaced, meeting renewable energy mandates.
