Biomass Stalks Pellet Production Line

We offer this Biomass Stalks Pellet Production Line in different specifications that meet on patrons
demand. These are widely appreciated for their durability, sturdy construction and corrosion resistance.

Definition of stalks pellet production line:
Using crop stalks as raw material, multiple processing steps are carried out to finally produce biomass pellet; straw pellets have good volatility, flammability, less ash, more fuel saving, lower cost of use, and good economic and social benefits. Stalks pellets can be widely used in biomass power plants, biomass steam boilers, household fireplaces, drying furnaces and biomass gasifier, it is an efficient and clean renewable energy source.

Raw materials:
Mainly wheat stalks, corn stalks, reed, straw, rape stalks and so on.

Process introduction:
The crop stalks is first coarsely grinded by a rotary cutter to 3-5 cm, and then finely grinding by hammer mill into fine grass cuttings, and the size is about 3-4 mm. Then, the raw material with 40% moisture content is dried to about 15% through a three-layer drum dryer, and finally granulation processing is performed. The processed finished pellets are 6-10 mm in diameter, and the pellets are cooled and packaged by a small bag packing scale 20-50kg/bag for easy transportation and sale. The stalk pellet complete project produces 6 tons per hour of biomass pellets, the total power of the equipment is about 1250kw, the workshop covers an area of 3000m2, including raw material warehouse and finished product warehouse; the whole line is compact in design, reasonable in structure, meets environmental protection requirements, and can be customized design according to customer requirements.

Process section:
Straw rotary cutting machine is pretreatment equipment for crop stalks. It can crush long straw, stalks and other materials to 3-5CM. Rotary cutting machine is with large diameter feeding roller. It can be loaded by manual or mechanical truck grab, etc for feeding. After the straw is coarsely grinded, it is finely grinded by hammer mill, and the size is about 3-4 mm. After grinding, it is transported and pneumatic transmission by the fan suction air pressure, and the grinding work has no dust discharge. The hammer mill in the grinding section of complete stalks pellet production line is a water droplet type structure with high grinding efficiency; the hammer mill rotor can be operated in forward and reverse directions to improve the service life of the hammer blade; the direct transmission mode of the motor is adopted, the transmission efficiency is high, and the maintenance is convenient.

Drying section :
The complete stalks pellet production line is equipped with a three-layer tumble dryer in the drying section, adopting a three-return form, small floor space occupation, high drying efficiency, small heat loss, and the heat exchange rate of the dryer is over 90%. The heating of the dryer is the automatic feeding of the pneumatic conveying equipment, which eliminates the need for labor and reduces the labor cost of the customer. The sawdust moisture after drying is about 13-18%.

Pelleting section
Six sets MZLH508-L vertical ring die pellet mill are designed in the pelleting section; the biomass particles are 6-10mm in diameter, and the biomass pellets have high calorific value, no pollution and low ash, which can be widely used in biomass power plants, biomass steam boilers, household fireplaces, drying furnace
