Congo 1-1.2 T/H Wood Pellet Plant

Construction content and scale

The small wood pellet plant in Congo project uses idle land, and the factory, office area and dormitory have been built. The project covers an area of ​​about 17 acres (1333m2), mainly equipped with a biomass pellet production line, with an annual output of 2,500 tons of biomass environmentally friendly pellet fuel.

The project factory is a 1F steel shed structure building. The details of the small wood pellet plant in Congo project construction are shown in the table below.

Production scale

The small wood pellet plant in Congo project products and production scale are shown in the table below:

Production Equipment for Congo wood pellet plant

Process design

1. The raw materials of the small wood pellet plant in Congo project come directly from the customer's timber mill, with a moisture content of ≤20%. After the raw materials are collected, they are piled in the raw material area for standby use, and the sawdust is directly sent to the pelletizer by the conveyor belt.
2. Drying: The biomass pellet burner is used to burn biomass pellets for heating. The heat generated by the combustion enters the drying cylinder to dry the materials with high water content, so that their moisture content is reduced to less than 5%. The dried materials enter the pelletizing process.
3. Granulation: The coarse powder material is fed into the extrusion bin of the biomass pellet machine from the feed hopper, and the crushed material is squeezed into the inner hole of the mold by the pressure roller. The mold is hot extruded and formed. During the extrusion process, the friction of the material generates heat, which is about 40°C. The extruded pellet is cut into cylindrical particles at the exit of the pelletizer. The whole process is physical extrusion molding without adding any binder.
4. Packaging: After the cooling and screening process, the prepared particles are directly packaged and sold.

General layout design

According to the information provided by RICHI engineers, during the design process of production line layout, we try to make reasonable use of the plant area, so that each area is reasonably and compactly arranged, which is convenient for production operation and production management, while ensuring the logistics capacity and simplicity of the production line. The small wood pellet plant in Congo project is divided into production area, office and living area.

The production area is arranged from south to north, with the raw material area, pelletizing area and finished product area located to the east of the pelletizing area. The project office area is located in the southwest of the production area, and the living area is located in the northeast of the production area.

From the overall layout of the entire building, the functional areas of this project are clearly divided, the production area and the office and living area are separated, and the project production has little impact on the office and living area.

The small wood pellet plant in Congo project plane layout reasonably arranges each functional area according to the production process requirements and the terrain characteristics of the project site, making full use of the limited site, and the layout is convenient for the entry and exit of raw materials and the transportation of products. Therefore, the plane layout is reasonable.

How to build a wood sawdust pellet production line in Congo?

It is feasible to build a wood sawdust pellet production line in Congo because Congo has rich wood resources, especially Congo-Brazzaville, which has a wide forest coverage area and a variety of high-quality tree species. ‌

Congo-Brazzaville's forest resources mainly include national production forests, protected forests and permanent production forests, most of which are located in the north, with a large number of high-quality mahogany and hardwood. Despite illegal and unsustainable logging activities, Congo-Brazzaville has a relatively low deforestation rate, which provides a foundation for the development of its wood industry. ‌

The specific steps to build a wood sawdust pellet production line include:

1. ‌Raw material collection and storage‌: Utilize Congo's rich wood resources to collect sawdust, wood chips and other raw materials to ensure a stable supply of raw materials.
2. ‌Crushing and drying‌: The wood is crushed into sawdust by a wood crusher, and then the sawdust is dried using a dryer to meet the needs of subsequent pelletizing.
3. Pelletizing‌: The dried sawdust is fed into a pelletizer and made into pellets by extrusion molding.
4. Packaging and storage‌: Finally, the pellets are packaged for easy storage and transportation.

The degree of automation of the entire wood pellet mill line can be adjusted according to specific needs, and corresponding equipment is available from small household production lines to large industrial production lines. For example, a small household production line can produce up to 300 kilograms per hour, while a large production line can produce more than 10 tons per hour.

In addition, Congo's timber industry has great development potential. Congo-Brazzaville is rich in forest resources, especially in the northern region, with a large amount of high-quality mahogany and hardwood. With the development of industry and agriculture, the demand for biomass fuels has increased. As a renewable energy source, wood sawdust pellets have broad market prospects and economic benefits.

How Many Biomass Pellets Can you Get From One Ton Biomass Material

There are various factors which determine the quantity of biomass pellets produced by good completely biomass wood pellet production line:

• The Cleanliness of The Biomass Pellet Plant Biomass Materials 

The cleanliness of the raw materials you are using for pallet production will always determine the quantity of pellets you will produce. The higher the cleanliness of the raw materials being used the more biomass pellets you get from the raw materials. Therefore make sure you always use clean raw materials.

• The Moisture Content of The Biomass Pellet Plant Raw Materials

There is a very thin line between the moisture content in the raw materials and the biomass pellet plant production output. The acceptable moisture content is between 8% to 15% and as much as drying can leave the materials completely dry, make sure you always maintain the content between this range. The higher the moisture content the raw materials have the lower the pellets you will get from them.

• The Biomass Pellet Plant Biomass Pellet Machine You Choose

Just relying on the moisture level and the cleanliness of the raw materials for high production of the wood pellets is not enough to guarantee you maximum production. The type of biomass pellet machine you are using is also very important when it comes to quantity and quality of the pellets. Reliable biomass pallet machine in cooperate the ring die and the roller in a perfect way thus attaining over 95% production rate. So the type of wood pellet manufacturing machine you choose plays a major role in the amount of pellets produced. 

The above factors play a major role in biomass wood sawdust pellet plant especially on the output quantity and quality, but there effects vary depending on different situations.
