Palm Kernel Shell Pellet Mill

Brief Introduction

The palm kernel shell pellet mill is a hard biomass forming equipment specifically developed for the characteristics of palm kernel shells: high hardness, strong wear resistance, and high lignin content. Palm kernel shells are hard and rough, and ordinary pellet mills easily encounter problems such as rapid mold wear, pressure roller slippage, loose forming, and low output. The palm kernel shell pellet mill adopts a high-torque transmission system, thickened alloy molds, and a reinforced wear-resistant pressure roller structure to specifically solve the forming problems of palm kernel shells. The palm kernel shell pellet mill can batch-press waste palm kernel shells from palm oil plants into high-density, high-calorific-value, and uniformly sized biomass pellets. The equipment has strong load-bearing capacity, stable operation, and can operate continuously for 24 hours. It is widely applicable to palm processing enterprises, biomass fuel plants, and solid waste recycling plants, and is a specialized equipment for the resource utilization of palm kernel shell solid waste.

Working Principle

The palm kernel shell pellet mill uses a purely physical high-pressure extrusion molding principle, requiring no adhesives throughout the process. The crushed and moisture-conditioned palm kernel shell raw materials are fed into the pellet mill's molding chamber. The mill's pressure rollers continuously crush and knead the hard palm kernel shells under high pressure, densifying them. Friction heating activates the palm kernel shells' lignin, utilizing the material's own binding properties to achieve solidification and molding. The material is forced through the die orifices under high pressure and then automatically cut into standard-length pellets. After natural cooling and setting, it produces highly formed, compact palm kernel shell pellets. The entire process is automated, with a high molding rate and no material waste.

Suitable Raw Materials

The pks pellet mill primarily processes palm kernel shells, palm shells, empty palm fruit bunches, palm waste, and other hard palm-based materials. It is also compatible with processing various hard nut shells such as walnut shells, cashew shells, and coconut shells. Additionally, it is suitable for processing common agricultural and forestry biomass materials such as sawdust, bamboo shavings, and straw. Raw material moisture content of 12%-18% is sufficient for direct processing, making pretreatment simple and reducing the barrier to mass production.

Application Areas

Palm kernel shell pellet mills produce palm kernel shell pellets with high calorific value, low ash content, and complete combustion, making them a high-quality clean energy fuel widely used in industrial boiler heating, biomass power plant power generation, and constant temperature heating in factories and greenhouses. The high-quality palm kernel shell pellets are suitable for market sales and export, and can also be used as raw materials for biochar and activated carbon production. Simultaneously, they effectively solve environmental problems such as waste accumulation and pollution from incineration in palm factories, achieving the recycling of waste resources and turning waste into treasure.
