The Production of Wood Pellets

The advancement in technology has allowed the production of wood pellets on a small scale. The rising demand for pellet heating over the past couple of years has made many people seek the skills for making pellets for their own use, instead of having to buy commercially made pellets. One important requirement in the making of pellets is a pellet machine. Apart from this machine, one also needs a hammer mill, among other simple tools.

Pellets are made by compressing wood or other forms of biomass into pellet form. That is why some people refer to the pellet machines as pellet presses. The process of making these pellets is not that complex, provided you have the right tools and raw materials. Therefore, you must have the raw materials, which include wood chipping, or grasses, agricultural waste, grains, or any other form of biomass. If you have large pieces of wood, you must first use a hammer mill or chipper to break them down.

The wood to be pelletized should first be dried, but leave a small fraction of the moisture content i.e. 10-20%. You may dry this wood naturally or use a dryer to hasten the drying process. You may also require binding agents such as vegetable oil, flour, or cornstarch, especially if the raw materials you are working with do not contain sufficient natural binding compounds, and the pellet mill that you are using does not produce the require heat levels during pelletization.

During the pellet production process, the pellet mill presses the raw material into a die, by using a roller. The pellets thus formed will take the size and shape of the holes within the die. This process produces a lot of heat, due to the friction and pressure involved. This heat is important since it melts the binding agent into the wood.

The knowledge of Wood Pellets

Introduction a benefit machine – wood pellet machine. Wood Pellets are a type of biomass fuel, generally made from waste wood. This takes the form of either compacted sawdust produced as a byproduct of saw-milling or grinding wood chips produced from logging operations. The pellets are extremely dense and can be produced with a low moisture content (lower than 10%) that allows them to burn at a very high combustion efficiency. Now, millions of households around the world either use wood pellet fuel as their primary fuel source, or at the very least as a supplementary heating source.


What about Wood Pellets energy output and efficiency? High-efficiency wood pellet stoves and boilers have been developed in recent years, offering combustion efficiencies of over 90%. Wood pellet boilers – having limited control over the rate and presence of combustion compared to liquid or gaseous-fired systems – are particularly suited for hydronic systems due to the hydronic system’s greater ability to store heat.

In 2005, the demand for pellet heating has increased in European and North America, and a sizable industry is emerging and pellet availability and cost may be an issue. However the pellet production is increasing but several new pellet mills online in 2008-2009.

In the meantime, thousands of people are moving towoards a more sustainable and stable fuel choice – Wood Pellets.
