Biomass straw pellet fuel production line

Product Specification

In recent years, environmental awareness has significantly increased, and coal use has almost completely disappeared both domestically and internationally. Consequently, businesses have turned to natural gas, oil, or electricity, but these energy sources are relatively expensive, placing a significant financial burden on businesses. This has led to the development of biomass pellet fuel production lines. These pellet fuels are made from waste wood chips, straw, sawdust, peanut shells, rice husks, and other materials. Through simple processing, they offer low cost and high combustion efficiency.

Raw Material Compatibility Analysis
Wood Raw Materials (Pine/Fir, Moisture Content Required: 12-15%)
Agricultural Residues (Rice Husks/Corn Straw, Requires 1-2% Binder Addition)
New Raw Materials (Palm Fruit Bunches/Coffee Husks, Calorific Value Comparison)
Pretreatment Standards
Particle Size (3-5mm Screen Passage ≥95%)
Drying Control (Drum Dryer Exit Moisture 10-12%)

1. Crushing and Screening: After all raw materials are crushed by the crusher, they are filtered through a sieve with the appropriate mesh size. Powder that meets the requirements passes through the sieve and enters the drying drum; powder that does not meet the requirements continues to be crushed in the crushing chamber.
2. Drying: The hot air and flue gas generated by the hot air furnace pass through the fire grid. The high-temperature hot air and flue gas are thoroughly mixed with the raw material powder from the crusher in the drying drum, heating and drying the raw materials. At the end of the drying drum, the raw materials enter the second-stage cyclone solid-gas separation tower under the action of a high-pressure centrifugal fan, where the flue gas and water vapor are completely separated from the raw materials.
The separated flue gas and water vapor are directed to the spray tower for treatment and then discharged through a 15-meter-high exhaust stack. The separated dry raw materials are transported along a pipeline by a screw conveyor to the dry raw material preparation room or directly to the molding machine for molding.
From the crusher inlet to the dry raw material (semi-finished product) preparation room outlet, the raw materials are separated only in the cyclone separation tower. A dust collection duct is installed at the top and leads to the spray tower outlet. All processing is carried out in a closed system. 3. Pressing and Molding: The semi-finished dry materials in the standby room are conveyed directly to the molding machine via a screw conveyor for molding. Based on customer needs, a biomass pelletizer is equipped to produce pellets of varying specifications. The pellets are then cut into finished products of a specific length by an outlet cutter.
4. Cooling: Due to the high pressure and temperature of the newly formed products, they are conveyed to a cooling tower via a bucket chain conveyor for cooling. Natural air cooling is primarily used during this process.
