Raw materials 

Suitable raw materials: Wood waste(a variety of spices of trees, lumber, timber, shrubs, sawdust, saw shavings, twigs and branches). Sawdust, groundnut shell, sugarcane biogases, caster shells/stalk, coffee husk saw dust, paddy straw, sunflower stalk, cotton stalk, tobacco waste, mustard stalk, jute waste, bamboo dust, tea waste, wheat straw, palm husk, soybeans husk, leaves, grass, coir pitch barks/straws, rice husks, forestry wastes, wood chips and other kind of agro wastes(rice husks, corn cobs, peanut shells, sunflower seed shells, coconut shuck, coffee grounds, straw stalks, cotton stalks, palmempty fruit bunches).

Finished pellets

Production Flow

A complete wood pellet line includes several sections:

raw materials pretreating section, drying section, crushing section, pelletizing section, cooling section, screening section and packing section.

1. Raw materials pretreating section

Drum Wood Chipper (chip the raw wood into small pieces);

If raw materials are grass or corn stalk, we need to use chaff cutter.

2. Drying section

Dryer (reduce raw materials' moisture to a suitable level for pelletizing);

The best moisture content to pelletize is about 14-16%. Raw material shall be pretreated well to achieve regulated moisture content and size. Generally, moisture content of material ought to be about 13%-15%.

3. Crushing section

Hammer Mill (grind the small pieces of wood into nearly powdery form for easy pelletizing);

Depending on the different input material, we fit out the suitable Crushing machines. If the raw material is the Straw Baler, we developed the series Baler Crusher adopting the foreign advanced technology. If the raw material is big logs with diameter less 300mm or big timber cutter, our BX-Series Chipping and Crushing Machine is your best choices; while SFSP-series Hammer Mill is widely used to crush each kind of straw, wood chip, tree branch, bark and leftover bits from agricultural wastes. The best moisture content in the Crushing Process is less 20%, and the thickness of the wood chip is less 5mm.

4.Pellet making section

Wood pellet machine takes biomass waste as raw material to make pellet fuel which is a kind of renewable energy replacing fossil fuel. Pelletizing is the process of making waste materials into solid fuel. The objects are used for burning purposes. Wood pellet machine is used to process raw materials into wood pellets. It is the corn component of the whole line, which can decide the capacity of the whole wood pellet line.

5. Cooling section

Cooler (cool down the output pellets to avoid accumulation of heat that may destroy pellets);

6. Screening section

Sieving (remove the dusts and crushed pellets);

7. Packaging section

Packing (pack the pellets into bags of required sizes);
