Biomass energy is second only to coal, oil, and natural gas one of the world's total energy consumption 4th. Experts predict that biomass energy is likely to become an important part of the future sustainable energy system. In the middle of this century, using new technology to produce all kinds of biomass alternative fuels will account for more than 40% of total global fuel consumption.
According to the demand of the market, our technical team designs and manufactures the equipment for biomass pellet production lines, which are suitable for biomass material with 35-56% moisture to make pellets, such as sawdust, bamboo shavings, wood shavings, barley straw, oat straw, wheat straw, rye straw, rice straw, rice husk, bagasse, sorghum straw, corn straw, beans stalk, peanut vine stalk, etc. We also help optimize the drying and pelleting process according to the properties of different biomass materials, production scale, application requirements, cost control, automation level, and site condition.
The pellet machine uses the die roll extrusion principle, the agriculture residues biomass raw materials are processed into solid molding fuel, this will realize continuous and stable production of industrialization. The processing route uses one-time drying, secondary crushing, continuous feeding, and adjusted feeding mixed process combining, the particle shaping fuel rate of 98%, bulk density, and particle density are high.
Detailed introduction of sawdust drying and pelletizing production line
I. Pretreatment system
Raw material crushing and screening
A double-shaft crusher is used to crush logs/wood blocks to a particle size of ≤30mm, and a magnetic separation device is equipped to remove metal impurities (iron removal efficiency ≥99%). Pre-dehydration treatment reduces the initial moisture content from 40%-60% to 20%-30%, improving drying efficiency.
Particle size classification
The vibration screener divides the sawdust into coarse material (≥5mm) and qualified material (≤5mm), and the coarse material returns to the crushing process for cyclic treatment37
II. Drying system
Core equipment selection
Drum dryer: drum inclination angle 1°-5°, speed 3-8rpm, built-in spiral lifting plate to achieve multi-stage temperature control (80-400℃ gradient adjustment)
Heat source configuration
Biomass burner (fuel cost is 30%-40% lower) or gas boiler (thermal efficiency ≥85%). Equipped with waste heat recovery system to reduce energy consumption by 25%-35%.
III. Pellet forming system
Pellet machine configuration
Ring die pellet machine: suitable for hardwood raw materials, mold compression ratio selection (pine 1:6, miscellaneous wood 1:8)
Flat die pellet machine: suitable for small and medium production capacity (1-5t/h), maintenance cost is 30% lower
Process parameter control
Feed particle size ≤3 mm, moisture content 10%-15%. The mold temperature is maintained at 60-80℃ to prevent wood tar from sticking.
IV. Post-processing system
Cooling and shaping
The counter-current cooling tower cools down to below 40℃, the cooling time is 15-20 minutes, and the particle hardness is increased to ≥97.5%
Screening and packaging
The vibration screening machine removes powder and broken particles, and the purity of the finished product is ≥98%. The fully automatic packaging machine supports 25kg/bag or ton bag specifications, and the packaging speed is 30-50 bags/hour.
Main Machines of Production Line: Wood Chipper, Wood Crusher, Drying Machine, Glue Mixer, Presswood Pallet Machine, Mold Temperature Controller.
Automatic material spreading, automatic hot pressing, automatic push-out and automatic stacking. can produce 180 pieces of wood pallet per hour.
Fully automated production solutions. In the entire production line, only one or two staff members are needed to handle normal operations.
Reusing waste wood, sawdust, wood chips, straw, coconut fiber (coir) and other fibers can significantly reduce the cost of raw materials.
The pressed wood pallet is of high quality with smooth surface, high loading capacity, good performance in water proof resistance and non-fumigation.
By simply changing the compression molding, pallets in varied shapes/sizes could be produced. Meet the needs of various uses.
Heat sources can be supplied in a variety of ways. The energy consumption is low. It is an ideal option to recycle wood waste in an environmentally friendly way.
