Fuel wood pellets are a type of solid biofuel produced from compressed organic material or biomass. Pellets are usually made of industrial waste, food waste, energy plants, biodegradable agricultural residues and debarked lumber. Wood pellets can be used as fuel sources for power generation, municipal heating, and cooking. The price growth for fossil fuels the demand for wood pellet has dramatically increased in the countries of Europe and North America.

Wood Pellet Price Factors

Pellet fuel costs depend on several factors:

Wood Pellets Price Comparison

Bulk Wood Pellet Prices

Buying pellet fuel in bulk costs $250 per ton on average. This is a good way to stock up on fuel, but you’ll pay extra if you need it delivered. Delivery costs an additional $50 to $100, depending on how far you live from the purchasing site.

Wood Pellet Prices Per Ton

You can order 50 40-lb bags (one ton) of pellet fuel for $250. Depending on the type of pellet fuel, buying in bulk could cost up to $380, or $480 including delivery.

Bag of Wood Pellets Cost

Pellets are normally sold in 40-lb bags and average $5 per bag. The type of pellets and where you order them from also factor into price. Expect to pay anywhere from $4 to $9 for one 40-lb bag.

Where Can I Buy Cheap Wood Pellets?

Inexpensive wood pellets generally have low calorific value. After all, if a company wants to be profitable, the cost is not high, and the price is low. Instead of buying cheap wood pellets, it is better to produce wood pellets yourself.

Raw material preparation

To prepare the raw materials is the first thing when we make wood pellet. For small wood pellet plant, the raw materials quantity is not much. If the wood pellet is for personal use, the raw materials are normally the crop waste in the farmland. If the small pellet plant produce wood pellet for commercial purpose, the raw materials are normally the wood shavings collected from saw mill nearby. But for large wood pellet plant, the preparation of raw material become a serious problem which impact the pellet plant capacity directly. As the demand of raw materials for a large pellet plant is massive, the wood shaving quantity of a saw mill is not enough for a large pellet plant. Therefore, a large pellet plant usually use wood logs and branches as raw materials, or to find some saw mills and sign a long term wood shavings supply contract with them.

Initial size reduction

For large pellet plant, when the raw materials are ready, the first thing to do is raw material size reduction. The raw materials to produce wood pellet must be under the diameter of 5mm, so the logs and branches must be processed into small pieces. In this stage, the large pellet plant usually uses the wood chipper, which is a common size reduction equipment that can cut the wood logs and branches into small wood chips with a diameter no mor than 40mm in order to be further processed. On the contrary, this is not a necessary step for the small pellet plant. If the pellet plant use wood shavings as a raw material, that means the raw materials has already been processed into small pieces in the saw mills, so there is no need to use the wood chippers to cut the raw materials agairn.

Drying

For large wood pellet plants, after the initial size reduction step, the raw materials must be dried. In order to produce high quality wood pellets, the raw material must maintains a moisture content of 8% – 12%, so the raw material must be put into a dryer to reduce its moisture content. The most common dryer for large pellet plant is the rotary drum dryer, which is the most cost effective choice for large pellet plant. The drying process is also a necessary step for the small scale pellet plant to produce commercial wood pellet.

Initial sieving

For large wood pellet plants, after the drying process, the raw material will be sieved to separate the contaminants such as stone and metal particles away from the wood raw materials. These contaminants may cause the mechanical failure of the pellet mills, so if the raw materials of your pellet plant has the potential to be contaminated by these solid particles, it is necessary for you to sieve the raw materials before fed them into the pellet mill. The machines for the initial sieving process is normally a de-stoner or magnetic separator. Fo small scale pellet plant, due to its limited capital, this is not a necessary step.

Grinding

Grinding is also a size reduction step to make wood pellet, it is a necessary step for both large and small pellet plants. During the grinding process, the raw materials will be fed into a hammer mill which will grind the raw materials into smaller pieces with a diameter under 5mm. But the hammer mill can only process the wood raw materials with a diameter no mor than 50mm, therefore, the wood logs and branches can not be fed directly into the hammer mill, they must be processed by the wood chipper first.

Pelletizing

After the grinding process, the wood raw materials are reached the size and moisture requirements for wood pellet manufacture. Therefore, the following step is to pelletize the raw materials into wood pellet. The machine used to pelletize the raw materials into wood pellet is called pellet mill. There are two kinds of pellet mills, ring die pellet mill and flat die pellet mill. Ring die pellet mill has a capacity over 1ton per hour, it is used for large pellet plant. Flat die pellet mill has a capacity about 500kg per hour, which used for small pellet plant.

Cooling

After the pelletizing process, the wood pellet is very vulnerable. It has been press over and over in the pellet mill, which makes it hot and easy to be deformed. To make the wood pellet regain its proper rigidity and temperature, the wood pellet will be fed into a pellet cooler right after the pelletizing process. The types of pellet cooler can be divided into three types, the horizontal cooler, the vertical cooler and the counter flow cooler. All of them can be used to cool the wood pellet, but the counter flow cooler is my recommendation, as it is the most advanced pellet cooler in the market.

Final sieving

At this stage, the wood pellet sieving purpose is different from the initial sieving. This step only exist in the commercial wood pellet plant. As the commercial wood pellet has a strict limit on fine content, therefore, after the pellet cooling process, the wood pellet products will be sieved in order to separate the fine particles from the well made wood pellet. For the final sieving process, the vibrating screen is a common equipment for wood pellet plant.
