Biomass Pellet Maker is an environmentally friendly equipment that converts agricultural and forestry waste (such as sawdust, straw, rice husk, etc.) into high-density, regularly shaped biomass pellet fuel. These granular fuels are easy to store and transport, and greatly improve the combustion performance of biomass, mainly used in industrial fuels, power plant generation, and heating fields.
Working Principle
1. Pre treatment and feeding: Fluffy biomass materials (such as straw and sawdust) first need to be crushed and dried, processed into suitable sizes, and the moisture content reduced to around 10% -14%. The processed raw materials are sent to the feeding chamber of the pellet machine.
2. Extrusion molding: This is the most crucial step. Taking the common flat die granulator as an example:
The raw materials are evenly spread on a stationary flat template with many mold holes. The pressure roller installed on the spindle rotates with the spindle and rolls through the material layer. The pressure roller forcefully squeezes the raw materials into the mold holes. During this process, enormous pressure and friction generate heat, causing lignin in the raw materials to soften and exert a bonding effect, firmly binding substances such as cellulose together.
3. Cutting and discharging: The cylindrical material that is extruded from the other end of the mold hole is cut into particles of a specified length by a rotating cutter, and finally sent out through the discharging system.

There are several key factors to consider when choosing and using biomass pellet machines
Raw material characteristics: The fiber structure, lignin content, and moisture content of different raw materials are different, and it is necessary to choose a matching model and make targeted adjustments to the mold.
Capacity matching: The output range of pellet machines is very wide, ranging from several hundred kilograms per hour to several tons. We need to choose the appropriate model based on your production needs.
Energy consumption and efficiency: Pay attention to the power consumption per ton of equipment, and the efficient pellet machine can reduce energy consumption per unit of output while ensuring quality.
Mold maintenance: The pressure roller and ring mold are vulnerable parts that require regular inspection, maintenance, and replacement. Choosing materials with good wear resistance (such as 4Cr13) can extend their service life.
