Heavy Duty 22-23T/H Industrial Straw Wood Pelleting Plant For Bio Fuel Pellets In China

This is a large-scale heavy duty straw wood pelleting plant turnkey project that was put into production in 2019. All wood pelleting plant equipment and civil works are provided by RICHI. This is the second cooperation with the customer (China's Guizhou Lantian Biomass Energy Co., Ltd.) of this indutrial wood pellet plant for straw and wood shavings wood sawdust fuel pellets.

The first biomass pellet production line project that we cooperated with our customers was put into construction in 2014. The raw materials are bamboo sawdust and peanut shell, with an output of 5t/h and an annual output of 12,000 tons of biomass pellets. At present, this 5 ton per hour agriculture waste biomass wood pellet line is still in stable operation, and the products are mainly exported to Japan and South Korea.

First cooperation project: 5 tons corn stalk bamboo pellet production line

Under the current biomass energy policy and market background, the development prospects of large capacity heavy duty wood pellet line projects are very broad. Therefore, on March 6, 2018, 4 years later, the customer contacted us again, wanting to build a large scale biomass pellet production line with an annual output of 54,000 tons in the same area. The raw materials will be straw, wood shavings and wood sawdust.

It is worth mentioning that in the negotiation of the entire customized biomass straw wood pelleting plant project, no competitors appeared. According to the customer's response, based on the efficient operation of the first biomass pellet production line and the subsequent profits, he directly chose us as his second straw wood pelleting plant equipment manufacturer.

This 22-23t/h wood pellet plant site

In April 2019, after the customer approved our customized 54,000 tons straw and wood pelleting plant plan, we and the customer successfully signed the contract for this turnkey biomass peller processing project. For customers' 100% trust, our return is consistent high quality and low investment high return wood pellet manufacturing equipment. At present, this turnkey biomass straw wood pelleting line has been in stable operation.

According to the sales manager's feedback, the this heavy duty biomass wood pellet plant's products have obtained ENPlus Certification, and the sales area is expanding, and they have been exported to the European application markets such as Germany and the United Kingdom.

The industrial wood pellet plant project covers an area of ​​6710m², with a total construction area of ​​about 4,089.10m². The total investment of the wood pellet manufacturing plant project is 34 million yuan (about 5.32 million US dollars), of which the wood pellet producing equipment price is about 2.3 million US dollars. After the construction is completed and put into production, it will form an annual output of 54,000 tons of biomass pellet fuel production capacity.

The new build large capacity 54000 tons per year staw and wood pelleting plant has 15 employees working 8 hours a day, 300 days a year, and 2400 hours a year. The output of the pellet production line can be calculated to be 22.5 tons per hour, 180 tons per day, and 4500 tons per month.

Sawdust raw material warehouse

The raw materials of this turn-key wood biomass pellet plant project are mainly wood chips and straw. The wood shavings and straw, sawdust, mainly come from the waste scraps produced by the wood processing enterprises in the park. The straw sources are the straws of the surrounding agricultural enterprises to pack battlements.

After the raw materials are purchased, they are stored in the raw material warehouse and processed directly, and there is no environmental pollution in the link of collection and storage.

Serial number	Name	Consumption
1	Sawdust	52948.60 t/a
2	Straw	10589.72 t/a
3	Water	546 t/a
4	Electricity	50 (ten thousand degrees per year)
5	Biomass shaped particles	360t/a

Finished pellets from the wood pellet plant 

The main biomass straw wood pellet manufacturing machines are shown in the table below.

1. Preparation of raw materials for wood pelleting plant process

   The project's raw material straws are transported to the wood pelleting plant area using a sealed device, and the transport vehicles are covered with cloth. The raw materials are large in shape and contain a certain amount of moisture. The raw materials are stacked in a closed workshop.

2. Chipping section

   Use a super heavy duty wood chipper shredder machine to break the incoming straw into small pieces.
   

3. Crushing section

   Use a wood straw crusher (wooden scrape crusher) to crush the broken straw into small particles that meet the requirements of the heavy duty.

4. Drying section

   The straw of this large wood pelleting plant project enters the straw wood powder rotary dryer from the warehouse and is carried out in a sealed transmission channel, and only the particles whose humidity does not meet the requirements are dried.

   

   The average water content of the raw materials purchased in this large scale straw wood pelletizing plant project is about 20%, and it needs to be dried to a water content of 5% before production.

   The straw and wood biomass waste dryer of this 22-23t/h heavy duty straw biomass wood pelleting plant project is equipped with a biomass hot air stove and fuel is a biofuel pellet, and the temperature of the industrial biomass waste rotary dryer is controlled at 150-250°C. The high heat efficiency large rotary drum sawdust dryer of this turnkey biomass straw wood pelleting plant project is provided by the supporting biomass pellet hot blast stove, which burns 360t of biomass fuel per year.

5. Pelletization section

   The dried pellets are transported to the pelleting systems for straw wood machine through a conveyor for pelletization, and are formed into finished products by extrusion molding. The extrusion process of the heavy duty biomass pelletizer is a physical process without any adhesive and no chemical reaction.
   

6. Inspection section

   The unformed or unqualified wood straw pellets are screened out by the screening machine, and this part of the particles enters the heavy duty crushing electric shredder for reuse.

7. Packing and warehousing section

   The products that have passed the inspection are packed by wood pellets bagging machine and put into the warehouse.
   

   Finished product warehouse( the customer use ton package scale)

The total construction area of ​​this industrial straw fuel wood pelleting plant project is 4,089.10m². The main entrance is located on the south side. The south side of the land is located on the side of the park road and a comprehensive office building. The north is the production area. The main buildings of the production area are a production plant, a raw material warehouse, a product warehouse.

The burning ash of this large scale full automatic biofuel pellet plant for making straw and woood pellets project is calculated based on 20% of the fuel, and the output is about 72t/a. After being collected, it is sold as ash fertilizer.

For most biomass fuels, in addition to organic matter composed of carbon, hydrogen, oxygen, etc., they contain a certain amount of inorganic elements, including K, Cl, Si, Ca, Mg, Na, P, S and other major elements , And Fe, Mn, Cu, Zn, Co, Mo, As, Ni, Cr, Pb, Cd, Hg and other trace or trace elements. In the biomass combustion process, the residue formed after the inorganic components undergo a complex physical and chemical process is called ash.

Theoretically, the best solution for sustainable utilization of biomass ash is its application in agriculture, forestry, vegetation or soil. It can be directly recycled back to forests or used as fertilizer, which can not only reduce the application of artificial fertilizers, but also maintain the soil nutrient balance or increased soil nutrients can also reduce the loss of minerals, realize the recycling of nutrients and the true sustainable use of biomass energy.

1. Used directly or indirectly in agriculture and forestry vegetation or soil;

2. Used for soil remediation to improve soil activity. Combustion ash of herbaceous biomass such as straw contains a large amount of K, and also contains nutrients required for plant growth such as Ca and Mg. It is a high-quality material for the production of compound fertilizers.

   Compared with the burning ash of herbaceous biomass or agricultural waste, the burning ash of trees and bark is rich in Ca and almost free of N. Wood ash is often used directly or combined with nitrogen fertilizer in forest soil to slow the consumption of nutrients and soil. Acidification and increase the nutritional activity of K and P.
