Pellet plant from 1 t/h

A pellet plant produces fuel pellets from wood waste such as sawdust and shavings. We offer complete sets of plants of different design capacities. The production of pellets can become a profitable business, since they are a cheaper and more efficient source of energy compared to other types of fuel, more environmentally friendly than the use of petroleum products and coal.

The plant is fully automated, equipped with all the necessary equipment depending on the buyer’s needs, type of raw materials, power, required parameters of the final product.

Appointment of the production line

The complete line is designed for the production of pellets - granules from wood waste or other plant materials, which are used as fuel in boiler rooms, fireplaces and stoves. They have a high calorific value and are an environmentally friendly type of fuel.

Raw materials

The following types of raw materials are usually used for the production of fuel pellets:

• Wood waste: sawdust, shavings, wood chips (up to 20 mm in fiber).
• Plant waste - such as straw, corn husks, sunflower husks and other plant materials.
• Peat, sugar cane, coconut flakes.
• Agricultural by-products.

Products

Fuel granules - pellets. They are used as an alternative to traditional fuels such as coal, oil and gas.

Main parameters of pellets:

1. Pellet diameter: Typically the pellet diameter is between 6 and 8mm, but may vary depending on the type of pellet and the equipment used to produce it.
2. Length of granules: The length of granules can also vary, but usually ranges from 5 to 30 mm.
3. Moisture content of granules: The moisture content of granules should be low to avoid problems with storage and transportation. Typically the moisture content of the granules does not exceed 10%.
4. Ash content of granules: The ash content of granules depends on the type of raw materials used and can vary from 0.5% to 5%.
5. Calorific value of granules: The calorific value of granules depends on the type of raw material used and is usually around 15-18 MJ/kg.
6. Density of granules: The density of granules can vary depending on the type of raw material used, but is usually around 500-700 kg/m3.
7. Color of granules: The color of granules may depend on the type of raw material used and may be different for each type of granule.

Technology

Wood granulation technology includes several stages:

• Preparation: the wood must be cleaned of dirt, bark and other impurities.
• Crushing: The wood is crushed into small particles.
• Grinding: The shredded wood must be of a particle size suitable for further granulation.
• Drying: chopped wood is dried in special chambers at high temperatures. This is necessary so that the granules do not stick together and do not lose their shape during storage and transportation.
• Pelleting: Dry wood particles are fed into a granulator where they are compressed and formed into pellets. In this case, the wood particles stick together.
• Cooling: The granules are cooled in special chambers to room temperature to prevent them from deforming.
• Packaging: granules are packaged in bags or containers for storage and transportation.
