1. Proposed Wood Pellet Plant in Australia

Australia-based Kangaroo Island Plantation Timbers has been awarded a $5.5 million bushfire recovery grant from the Australian government to support the development of a biomass pellet plant and small-scale biomass power plant. The facilities will be located on at KIPT’s timber processing hub at Timber Creek on Kangaroo Island, a region that experienced a devastating bushfire in December 2019. The island is located off Australia’s southern coast approximately 550 miles northwest of Melbourne. Once operational, the pellet plant will be capable of accepting fire-damaged logs and any other logs that cannot be sold into export markets. Pellets produced at the plant are expected to be exported using the chip-handling facility at the proposed Kangaroo Island Seaport at Smith Bay. The project will also include a small-scale power plant to support the pellet mill. That facility will be capable of dispatching base-load power to the electricity grid.

2. How Does Australian Wood Pellet Plant Produce Wood Pellets

(1) 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.

(2) 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.

(3) 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.

(4) 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.

(5) 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 wood 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.

(6) 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.

(7) 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.

3. Australia 2-2.5 T/H Top Quality Easy to Maintain Wood Sawdust Pelletizing Production Line Project

In 2021.01.21, this Australia 2-2.5 T/H top quality easy to maintain wood sawdust pelletizing production line project was signed.The customer of this 2-2.5 T/H wood sawdust pelletizing production line project has just entered the biomass pellet fuel processing industry. During the negotiation process, we learned that the customer had negotiated with 12 wood pellet production line manufacturers. RICHI was the last one to enter his list of cooperation, but eventually became the most trusted China biomass pellet production line manufacturer by customers. Customers choose RICHI for many reasons. In addition to the quality of RICHI's products and brand awareness in many regions, customers value our full consideration for him. In addition, due to the limited budget of the customer, but in order to ensure the quality and service life of the equipment configuration of the entire wood pellet fuel production line, for the pre-treatment stage of wood, the customer purchases second-hand equipment in nearby areas, such as (Wood peeling equipment, Wood splite).

4. 2-3 T/H Wood Sawdust Pelletizing Production Line Price

Commercial good quality 2-3 t/h wood sawdust pelletizing production line investment cost in Australia is usually between 120000-270000USD.
