What is sawdust wood pellets?

Sawdust wood pellets are made from dried biomass that has been pulverized and passed through a pellet mill at high temperature and pressure. Compression action and high temperature cause the lignin in the biomass to melt, bind the particles together, and then form a solid pellet again after cooling.

How is the production process of sawdust wood pellets?

The wood pellet manufacturing process depends on the raw materials used but tends to include the following steps: raw material receiving, screening, crushing, drying, pelletizing, cooling, screening and packing package. The resulting product is a high-value, high-density pellet that is consistently shaped and therefore transported more efficiently than wood chips.

Wood pellets have a density up to 750 kg/m 3 and a lower heating value of 16.5 GJ/ton. For comparison, wood chips have a density of about 250 kg/m3 and an energy content of 13 GJ/ton. There are strict specifications for a number of parameters designed to homogenize the burning quality, safety and edible properties of wood pellets.

Why need wood pellet production line?

The wood pellet process is aimed at eliminating any fungal or insect pests, and the material is considered hygienic for export and trade.

In contrast, wood chipper  trade to Europe is constrained by the fact of achieving the required phytosanitary restrictions on wood chips from specific locations, including treating them at 56° C for 30 min, or in some countries a 2 m3 batch of woodchips can be treated by fumigation with methyl bromide or sulfuryl fluoride at 80 g/m3 for more than 24 hours.

This means that, to meet the rising demand for wood in Europe, a rapidly growing wood pellet trade is now available from abroad, mainly from the southern United States and British Columbia in Canada. 

Wood pellets are commonly used in older coal-fired power plants, as the material can be re-ground and pumped directly into the boilers, while woodchip combustion usually takes place in specialized fluidized bed plants. more usable. Therefore, wood pellets have a much larger potential market than chips.

Despite showing the benefit of increased transport efficiency, pelleting requires a considerable amount of energy. The low moisture content of biomass cannot be achieved without artificial drying, and it takes a lot of energy to grind the material into fine dust and pass it through the pellet machine.

The energy requirements for pelletizing that reduce potential greenhouse gas emissions are achievable compared to using chips. However, emissions savings can still be achieved, even when pellets are transported long distances.
