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

01

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 50-55%.

The optimum moisture content of the sawdust is 10-15%. The sawdust with higher moisture content should be dried before entering the sawdust pellet machine while the lower one can skip the procedure.

02

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.

03

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 .

04

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.

05

Pelleting 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.

06

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.

07

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.

Labeled with green and sustainable fuel, wood sawdust pellets are welcomed as a replacement of fossil fuels for energy production and pellet fuel production is subsided by majority of governments all around the world.

Comparing with oil, one ton of wood pellets reduces CO2 emission around 105 tons. While on the other hand, one ton of wood pellets equals to 2.8 barrels of #2 fuel oil in terms of net energy output.

Nowadays, with the favorable situations, wood sawdust pellet production business is developed with pleasing momentum. In USA market, the price for small bag wood pellets is around 170 USD/ton and the large package is abound 135 USD/ ton.

In Sweden, wood pellet price is about 150 USD / ton and the FOB price of bulk wood pellets is around 80USD/ ton. The situation is quite the same in other EU countries. Another words, to build a biomass pellet plant and produce wood sawdust pellet is quite a profitable business.

Some Thing You Need To Know About Biomass Sawdust Pellet Plant Production Technology

• The process of biomass sawdsut pellet compaction by wood sawdust pellet press machine/biomass sawdust pellet plant depends on many factors, related to fuel material and biomass sawdust pellet production process. One of the most important is the proper fragmentation of the raw material. In most cases, more fragmented raw material makes it easier to achieve the desired quality parameters of sawdust pellets.
   
• While the chipping of biomass prefers moist materials, for grinding, the material needs to be dried. As drying temperature changes the properties of the material, these may affect the grinding process. The aim of this work was to determine the influence of the drying temperature of biomass sawdust raw material in the range of 60–140 ℃ on the biomass grindability. To only determine this effect, without the influence of moisture, grinding was carried out on the material in a dry state.
   
• Biomass, regardless of origin and source (woody, herbaceous, fruit or water), from a chemical point of view, consists of three main components: cellulose, hemicellulose, and lignin. Thus, this kind of biomass is called lignocellulose biomass, and contains about 50% of carbon and about 6–8% hydrogen. This is the main reason why it is mainly used as a biofuel.
   
• From the point of view of the energy use of biomass sawdust, most of the energy accumulated in a given biomass is found in cellulose, hemicellulose, and lignin. Separately, the heat of combustion for cellulose and hemicellulose are similar: 17.6 and 17.9 MJ·kg, respectively. Lignin heat of combustion is higher and depends on the type of biomass sawdust: lignins from spruce and beech, but also from olive pomace, walnut, and hazelnut shells, have 27–28 MJ·kg.
  
  Therefore, the biomass sawdust heat of combustion is determined by the proportion of lignin in relation to holocellulose, however, despite the different levels of lignin, cellulose, and hemicellulose in biomass, the biomass sawdust heat of combustion has a narrow range of 18–22 MJ·kg.
   
• This energy homogeneity means that biomass from a wide range of sources is taken into account as raw material for the production of solid biofuels. These include coniferous and deciduous woods, different species of grasses, and dicotyledonous perennials as well as straw. Recently, more popular are shells, stones, husks, pomaces, and aquatic biomass.
   
• Therefore, biomass as a sawdust raw material for the production of solid biofuels is characterized by a very high diversity of physical properties such as moisture content just after harvest, specific and bulk density, or form. This heterogeneous raw material must be processed into a sawdust product that has a uniform quality.
   Only standardized quality sawdust pellet fuel allows for the combustion process to be properly conducted and allows for automation of the feeding and burning process, which is a standard in current modern heating systems.
   
• In order to obtain a high quality final product in the form of sawdust fuel pellets by sawdust pellet making machine, it is very important that the preparation of the sawdust raw material is carried out properly. The biomass during harvest usually has two disadvantages: high moisture content (MC) and a low degree of fragmentation (shoots, chips, chipped straw, etc.).
   
• These properties of the biomass sawdust raw material do not allow for its direct processing in a pressure agglomeration into pellets. Two stages are therefore necessary to prepare the raw material properly: drying and grinding afterward. The order of these steps is important because the grinding process is more efficient when the material is dry, where a humidity of less than 15% is recommended.
   

The depletion of fossil fuels and the need to reduce green house gas emissions has resulted in a strong growth of biomass utilization for heat and power production. Attempts to overcome the poor handling properties of biomass, i.e. its low bulk density and inhomogeneous structure, have resulted in an increasing interest in biomass densification technologies, such as pelletization in biomass sawdust pellet production line.

The global pellet market has developed quickly, and strong growth is to be expected for the coming years. Due to an increasing demand for biomass sawdust, the traditionally used wood residues from sawmills and pulp and paper industry are not sufficient to meet future needs. Therefore, new types and sources of biomass sawdust will be used more commonly in the future.
