1. The working principle of wet palm nut shell biomass pellet processing equipment

The pellet mill is the core equipment. Its working principle is "mechanical high-pressure extrusion + mold shaping," which uses external force to overcome the gaps between raw material particles, compressing loose fibers into high-density particles.

(1) Feeding and Pre-compression: The raw material is fed into the pelleting chamber at a constant speed through a screw feeder. The frequency conversion control of the feeder (speed 10-20 r/min) ensures a stable supply of raw materials.

(2) High-pressure molding: A pair of pressure rollers in the pelleting chamber use high pressure to extrude the raw material into the annular hole (hole diameter 8-12 mm) of the mold. The principle is to use high pressure to make the raw material fibers adhere tightly, while the frictional heat generated by extrusion (temperature rises to 60-80℃) further activates the binding effect of lignin, causing the raw material to form a continuous columnar body within the mold hole.

(3) Cutting and Demolding: Fixed cutters on the outside of the mold (blade spacing matches the particle length, usually 3-5 cm) cut the extruded columnar body, forming standardized particles. The particles are demolded by their own gravity and slight vibration of the mold, falling into the subsequent cooling system.

2. Characteristics of wet palm nut shell biomass pellet processing equipment

(1) High-Pressure Pelletizing Structure: The contact pressure between the pellet mill's pressure roller and the die is increased to 80-120 MPa (compared to approximately 50-80 MPa for ordinary wood pellet mills). This high-pressure extrusion forces the fibers to adhere tightly, while the frictional heat generated during extrusion (60-80℃) activates the lignin in the nut shell, enhancing pellet cohesion and preventing loose and brittle pellets.

(2) Special Material Die and Pressure Roller: The die is made of a composite material of "tungsten carbide coating + alloy steel substrate," with a surface hardness exceeding HRC60. Its wear resistance is more than 50% higher than ordinary die, effectively mitigating wear from trace amounts of silicon and calcium in palm nut shells. The pressure roller surface features anti-slip textures to increase friction with the raw material, preventing slippage and improving feeding efficiency. 

(3) Adjustable compression ratio design: The compression ratio of the mold can be adjusted according to the fiber content of the shell. When the fiber content is high, the compression ratio is increased to prolong the extrusion time of the raw material in the mold hole and ensure the forming density (final particle density ≥1.1g/cm³); when the fiber content is low, the compression ratio is decreased to increase the pelleting speed.

3. Application scenarios of wet palm nut shell biomass pellet processing equipment

(1) Energy production: Biomass power plants and combined heat and power (CHP) projects, replacing coal-fired power generation.

(2) Industrial heating: Steam boiler fuel in the textile, food, and chemical industries.

(3) Residential heating: Home fireplaces and small-scale heating systems, especially prevalent in palm-producing regions of Southeast Asia.

(4) Carbonization extension: Processed into palm shell charcoal or activated carbon for water purification and gas adsorption.

Core Processing Flow: A Four-Step Process Adapted to the Characteristics of Palm Nut Shells

The high moisture, high fiber, and impurity content of palm nut shells necessitates enhanced pretreatment and pelleting stages in the processing flow, as detailed below:

1. Crushing: 

A hammer mill is used to grind the nut shells into 2-5mm fibrous powder, while simultaneously filtering out residual long fibers to prevent entanglement in the equipment.

2. Drying: 

A drum dryer (hot air temperature 120-160℃) is used to reduce the moisture content to 10%-15%, preventing loose pellets during subsequent pelleting.

3. Pelletizing: 

The powder enters a high-pressure pelletizer (pressure 80-120MPa), where it is extruded into 8-12mm diameter pellets using a tungsten carbide-coated die. The frictional heat generated during extrusion activates lignin, increasing pellet hardness (≥60N); finally, the pellets are cut into standard 3-5cm length pellets.

4. Cooling and Packaging: 

High-temperature granules (60-80℃) are cooled to room temperature by an air cooler, and then unqualified granules are screened by a vibrating screen (the unqualified granules are returned for reprocessing); qualified granules are bagged by an automatic packaging machine (25kg/bag or ton bag) and stored in a ventilated and dry warehouse for sale.

1. Resource Recycling and Significant Raw Material Advantages: 

The raw material is a byproduct of palm oil processing, representing "waste reuse." It eliminates the need for additional arable land or deforestation, thus avoiding resource waste.

Palm nut shell production is stable and concentrated, with ample supply from major producing regions (such as Malaysia and Indonesia), ensuring continuous production line operation.

The processing generates no secondary pollution, transforming potentially rotting shells into clean energy while reducing waste impact on the environment.

2. Convenient Storage and Transportation, Low Overall Costs: 

The raw material has a natural density of 1.1, which further increases after processing into pellets. These pellets are small, lightweight, and less prone to breakage, significantly reducing storage space requirements.

The regular pellet shape facilitates mechanized loading and unloading and long-distance transportation, reducing transportation costs by more than 30% compared to loose shells or other biomass raw materials.

High combustion efficiency means less fuel is needed for the same heat demand compared to traditional fuels; and the low raw material cost results in significantly lower overall operating costs than coal, natural gas, and other energy sources.
