Why Make Sawdust Pellets with   sawdust pellet production line?

• Sufficient and cheap sawdust material source: Sawdust is the residue of wood processing factory. The amount of sawdust material is large and the price is cheap. Sawdust wood pellet mill and complete sawdust pellet production line can also be used to deal with life wastes such as leaves, straw and crops waste. It is a way to make waste profitable. And by making these biomass materials into fuel pellets, we no longer have worry how to dispose of these wastes.

Advantages of Sawdust Pellets



They are a sustainable resource.

They reduce energy imports and contribute to the national economy.

The amount of waste released to the environment after use is negligible.

They can be used to produce electrical energy.

They generate CO emissions below the thresholde.

They are easy to transport and the need for storage is less compared to wood etc.

They are manufactured from residual sawdust and similar waste materials without harming nature.

How to make quality wood sawdust pellets with sawdust wood pellet production line?

• 1,Raw materials preparation

  Transport sawdust or other kinds of biomass materials to your factory. Locate the plant near the source of raw materials, so that to minimize the transportation cost. As the wood sawdust arrived in the sawdust pellet machine plant, the moisture content should be tested.

  The moisture content gives the proportion of evaporable water in the total weight of material. The sawdust with high moisture content should be stored separately from the low moisture content sawdust. The production of 1 ton pellets needs the about 7 bulk m³ sawdust with the moisture content around 45-50%.

  The optimum moisture content of the sawdust is 15-20%. The sawdust with higher moisture content should be dried before entering the sawdust pellet machine while the lower one can skip the procedure.

  2,Drying system

  The wet sawdust should be dried before size reduction because the wet sawdust consume more power to be hammered than the dried one does. And also the wet sawdust may risk the screening by clogging or smearing the screen. Drying can be done by the wood sawdust drying machines.

  3, Cleaning & screening system

  The screening of the sawdust is to remove the stones, plastics, metals, or other hard materials that may damage the equipment. The stones and stone like hard materials are removed by a stone trap when the sawdust passes over the screen while the metals are picked up by a magnet .

4，Crushing system

The grinding section is meant to homogenize the sawdust to an even-size. In the piles and piles of sawdust there are might be wood lumps, dead knots, etc. which needed to be hammered so that they can pass the die holes of the sawdust pellet mill machines.

5，Crushing system

When the sawdust goes into the pelletizing chamber of the sawdust pellet mill machine, the lignin of the sawdust will be heated up to 120-130 ℃ by the heat produced by the running sawdust pellet machine and by which the lignin will be plasticized and binds the particles together to help to mold the pellets.

The sawdust pellets are molded by being pressed through the pellet dies of the sawdust pellet machines and then are cut off by the cutter with the desired length. During the pelletizing, the binder may be needed to improve the pellet strength and durability. Watch this video to see how a sawdust pellet mill works..

6，Cooling system

The moment when the pellets leave the sawdust pellet machines, they are hot and plastic. Then they need to be cooled down to become hard and rigid and to dry up so that the final moisture content after the cooler can be as low as 6% which may be increased up to 8 to 10 % by absorbing moisture from the surround air.

7，Packaging system

Before packaging, the pellets will be screened again for recycling the fines. And then the pellets will be packaged. For domestic users, the wood sawdust pellets are preferred to be packed into bags with the sizes of 12, 15, or 20 kg.

While for exporting, the sawdust pellets are usually shipped in one tone bags or in bulk which are usually wrapped in plastic to keep the moisture out. Compare with the large bulks or bags, the small bags are better for the pellets because the pellet are subject to less abrasion during delivery.
