10-12 T/H Biomass Pellet Production Line in Thailand

This 10-12t/h biomass pellet production line in Thailand project is the largest agricultural and forestry waste pellet plant project we have ever done in Thailand.

On October 9, 2018, a customer sent us an inquiry:

"Dear Rich Machinery,
I'm a consultant, who is working in a project feasibility study for a public university, where it is expected to produce and export to Japan, Denmark, United Kingdom and Italy wood pellets with ENplus A1 certification.
We are contacting you due that the name of your company appears as a wood pellet plant manufacturer in China and because we want to start creating the project networking to find the right allies through the whole supply chain.
We are interested in installing our 55.000 ton/year ENplus A1 wood pellet plant in Thailand next year with you if we find it beneficial for both of us.
We hope this letter becomes the first step for a meaningful relationship and we will be awaiting your kind reply by a person who available for further communications.
Yours truly,
Daniel
Consultant"

In July 2019, this 10-12 t/h biomass pellet production line in Thailand project was signed.

It is worth mentioning that the final project was not what the customer originally requested. The customer's raw materials also changed. He not only used wood waste, but also added a variety of agricultural waste as raw materials.

Therefore, in response to customers' raw materials and needs, our biomass pellet production line process has also changed. However, according to customer feedback, according to testing, the final pellet products still meet higher fuel pellet standards and can still be sold to Japan and other countries. in biomass power plants and other fields. The 10-12 t/h biomass pellet production line in Thailand project has a maximum employee capacity of 40 people, and production adopts a two-shift system, with each shift lasting 8 hours. Sometimes, peak and valley power are used to adjust to mid-shift and evening shifts, and night production is performed. There are 300 working days in the year.

• Pelletizing workshop: 10 biomass pellet mills (the biomass granulator physically rotates at high pressure and high speed to form cylindrical biomass particles);
• Slicing and crushing workshop: slicer and crusher (slicing and crushing to make the particle size less than 5mm);
• Cooling, screening and packaging workshop: conveyor, cooling screening machine, packaging machine (products around 40°C are transported to the cooling facility to cool to room temperature and then screened and packaged);
• Transportation: vehicle transportation, belt transportation (raw materials and products are transported in and out of the factory by vehicles; belt transportation is used inside the workshop);
• Raw material and finished product warehouse: raw material storage and product storage;
• Exhaust gas treatment project: bag dust collector: 3 sets, bag dust removal efficiency reaches more than 99%; Cyclone dust collector: 5 sets, cyclone dust removal efficiency reaches more than 90%;
• Noise prevention and noise reduction measures: purchase low-noise equipment, rationally arrange the factory floor plan; take certain vibration and noise reduction measures to reduce distance attenuation.

This 10-12 t/h biomass pellet production line in Thailand project mainly produces biomass pellet fuel. The main products and production scale are shown in the table below.

What raw materials were used in this 10-12 t/h biomass pellet production line in Thailand project? How many raw materials are used? How much electricity is used? How much water was used? In the table below you will clearly see:

Note: All raw materials come from surrounding farmers and wood processing plants. The average moisture content of raw materials is 24%

The main raw materials of the 10-12 t/h biomass pellet production line in Thailand project include waste wood blocks, sawdust, shavings, rice husks, etc. The raw materials are sliced, crushed, granulated, cooled, screened, and dried. Qualified products are packaged and stored in the warehouse.

The scraps, collected dust, and unqualified products are returned. corresponding process. Cooling adopts sieve machine air cooling. Raw materials and products are naturally dried without drying process.

01

Slicing:

This 10-12 t/h biomass pellet production line in Thailand project requires slicing the feed material, and cutting into small pieces is beneficial to the crushing process. The waste wood blocks are cut into small pieces by the slicer and transported to the large material warehouse.

The slicer of this project works for 4800 hours per year, and the slicing raw material is 48000t/a, so the slicing dust generated by the project is about 8.4t/a.

02

Crushing:

The small pieces of raw materials in the large silo are sent to the crusher for crushing through the conveyor belt. This biomass pellet plant project has a total of 3 sets of crushers with an annual crushing capacity of 66,660 tons. The aniseed is transported to the pulverizer, and the negative pressure airflow generated by the high-pressure fan sucks the wood chips into the wood chips and separates the wood chips from the air flow through the separation tube.

The separated air flow (with a small amount of fine powder) is released through the bag dust collector, and a small amount The fine powder is retained on the surface of the bag and is regularly discharged for reuse. Under the action of the air flow, the coarse wood chips rotate downward in the separation cylinder and fall into the air-closed device.

They are sent to the discharge pipe through the air-closed device and are discharged under positive pressure. Under the action of air flow, it is pressure-sent to the elevator through the conveying pipeline, lifted to the powder warehouse by the bucket elevator, and transported to the granule warehouse through a sealed auger conveyor.

03

Granulation:

The materials in the granule silo are transported to the wood biomass pellet granulator through closed transportation facilities. The granulation process is a closed production. During the granulation process, the screw extrusion generates high temperature, and the water in the raw materials is heated and evaporates, and the granulation process is completed.

The machine outlet will produce a large amount of water vapor mixed with dust particles. The amount of pellet raw materials used in this project is approximately 66,600 tons. The granular material rotates at high speed in the biomass pellet making machine mold and undergoes physical high-pressure extrusion to form a cylindrical-shaped biomass granule product.

The entire process is physical extrusion without adding any binder. The moisture content of the raw materials in this project is about 24%, and the moisture content of the finished product after granulation is about 8%.

04

Cooling screening:

Since the material will generate a certain amount of heat during the extrusion, granulation and molding process, the temperature of the discharged biomass pellet fuel is as high as 80-90°C. The structure is relatively loose and easy to break, and must be cooled to normal temperature.

05

Packaging and storage:

Therefore, after pelleting, the biomass pellets are cooled to normal temperature by a cooling fan, and then screened and dried to ensure the factory quality of biomass pellet fuel. The broken materials screened out by the screening machine are connected to the powder silo and directly used for production.YouTube

Thailand is one of the upcoming biomass and wood pellet exporters in the Southeast Asia region. Wood biomass pellet production has been gradually increasing in Thailand; however, the recent trend is more rapid.

Thailand has increased biomass wood pellet production for export and domestic use. Thailand has the potential to grow plants throughout the year, so biomass raw materials is readily available.
