When you are going to buy a wood pellet machine or build a wood pellet production line, one thing you must know is the wood pellet standard. It can help you choose a wood pellet mill manufacturer, help you improve the wood pellet production line process, and help you decide the market for your product.
When To answer the need for clarification at an international level, ISO is working on a series of International Standards on solid biofuel specifications and classes. This will provide concise and unambiguous criteria and methods for the characterization of solid biofuels made by wood pellet machines.
With the ISO 17225 series wood pellet standard, ISO is preparing almost 60 International Standards for solid biofuels on graded wood pellets, graded wood briquettes, graded wood chips, graded non-woody pellets, thermally treated and densified biomass fuels, etc. It comprises definition and classification standards as well as standards for chemical and mechanical testing. A standard on sampling methodology is also included as a necessary building block for accommodating certification and various schemes of credit accounting.
The main challenge for biomass fuels is that they are not homogeneous. The properties of biomass differ depending on the raw material. There are also different national interests and practices behind the production of solid biofuels made by wood pellet mill machines. The ISO 17225 series determines specifications and classes based on the origin and source of the solid biofuel raw materials: woody, herbaceous, fruit, aquatic biomass and blends and mixtures. Then, for each traded form like pellets, quality properties were selected separately but origin and source and moisture and ash content were specified for all traded forms.
The standards are intended for all stakeholders working in the solid biofuels supply chain, including fuel producers, traders, end users, authorities and policy makers. These standards will serve as a tool to enable efficient trading of solid biofuels and foster a better understanding between seller and buyer, as well as for communicating with wood pellet mill equipment manufacturers.

How to make high quality wood pellets? Use Wood Pellet Machine
As biofuel energy, wood pellet is a common kind of biomass pellets. Wood pellets made by wood pellet machines are actually wood particles (e.g., wood shavings and sawdust) compressed into small cylindrical pellets. They are usually made from wood waste, including sawdust, shavings, and wood chips, which are byproducts of the manufacture of lumber, furniture, and other forest products.

Wood pellets are under high pressure when compressed through the small holes in the wood pellet mill. RICHI wood pelletizer machine applys pressure to force the raw materials through holes that shape the pellets. Pressure and friction are used to increase the temperature of the wood, which in turn allows the lignum to soften and the wood fibers to be reshaped into pellets. And the woods natural lignin is the binding agent that holds the pellets together.
Wood pellets are denser than wood chip and have very good handling characteristics. They can be made from a wide range of sources of biomass with the result that pellets made from different feedstocks will have different energy densities and other characteristics.
What's the complete wood pellet machines plant process for ISO standard wood pellets?
Wood Pellet Making Process
Typically any raw material will require some form of processing prior to being pelletized. This can range from debarking if using whole logs (round wood) to shredding or grinding of pallets, ag products, or MSW. Once the product is shredded or ground, it could require further processing through a wood pellet hammer mill, depending on how it was received.
If the wood pellet raw material is wet (over 15%) it will need to be dried. After sizing and drying if needed, the product is now ready to be pelletized by wood pellet machine. Pellets can be made in a wide range of diameters and bulk densities, which is typically determined by the end use of the pellet.
The pellet machine ring die specifications can be changed, allowing for multiple sizes to be produced from the same wood pellet mill machine. In most cases pellets will exit the wood pellet machine hot (100-170 degrees) and must be cooled. This is done with a pellet cooler by pulling ambient air through the wood pellets.
Once the pellet made by wood pellet machine is cooled to ambient temperature, the pellets are screened to remove any fines that may have been created during the process. The pellets are now ready to be packaged, stored or sold in bulk.
How to buy a new wood pellet machine?
The wood pellet machine needs to crush and dry the wood wastes, such as wood sawdust, wood shavings, wood chips, wood log, etc., and then use the wood pellet making machine to suppress the pellets. In recent years, the wood pelletizing machine manufacturing industry is booming.
The sales volume of biomass wood pellet machine is relatively high, and a large number of producers rush into the market, resulting in the phenomenon of uneven quality of the machines on the market. Some manufacturers renovate and sell the old pellet press machines directly, which increases the worry of many customers when they buy them.
Our company has more than ten years of experience in wood pellet machine. In order to avoid customers being cheated, we share several skills to identify whether the wood pellet granulator machine is a refurbished wood pellet machine.
- Observe the working panel of the biomass wood pellet machine, and there will be irreparable scratches on the working panel of the refurbished pellet machine.
- Check the accessories on the wood pellet machine, such as the edge of the screw. The screw of the refurbished machine will leave traces.
- Check the plug part of the bolt. If it is a refurbishing wood pellet machine, there will be traces.
- Check the corner of the wood pellet machine. There are many scattered particles in the renovation opportunity.
We all know the principle of "one cent, one share of goods". Price is not the only choice for wood pellet machine. We hope that you will not be blinded by the appearance of low price machinery, and we will choose a powerful wood pellet machine manufacturer.
The life of a refurbished wood pelleting machine can not be compared with that of a new one. Every wood pellet mill machine will pay a high cost, if you buy a refurbished machine caused by the loss is very much outweighed.
What should be considered to start wood pellet production business?
When developing a business plan the following things should be considered top priorities.
- What raw materials will be used?
- How much of this raw material can be obtained at a price point that works within your business model?
- What is the incoming moisture content?
- What is your target market, residential fuel, industrial grade fuel, animal bedding, feed, etc.?
- What is your market area?
- Do you intend to sell your end product wholesale or retail?
- What is the market volume potential for the end product in your target market area?
- What is the value of your end product wholesale and retail in your target market area?
- What volume do you plan to produce?
