Pellet Mill Plant
The pellet mill plant mainly uses processes such as crushing, drying, granulation, cooling, and packaging to process various biomass agricultural and forestry wastes, industrial wastes, and municipal solid wastes such as wood, straw, fruit shells, and grass raw materials into pellet products.
Depending on the process, the application of finished pellets is also different. Currently, they are mainly used as fuel for power plants and boilers, livestock and poultry feed, organic fertilizer, cat litter, and animal bedding.

1. Collection of raw materials
The raw materials for pellet mill plant are usually renewable organic wastes such as wood waste, agricultural waste, animal manure, etc. The process of collecting raw materials should ensure the diversity of raw material sources to reduce dependence on a single source.
At the same time, environmental protection should be considered during the collection process to avoid environmental pollution.
2. Raw material pre-treatment
Raw material pre-treatment mainly includes crushing, dry explosion, sorting and other links. Crushing mainly breaks large pieces of raw materials into small pieces to facilitate subsequent processing.
Dry explosion mainly removes moisture from raw materials to facilitate granule suppression and prevent granules from becoming moldy during storage. Sorting is mainly to remove impurities in raw materials, such as stones, metals, etc., to ensure the quality of produced pellets.
3. Drying
The raw materials with high moisture content need to be dried to remove moisture and improve the stability of the pellets. Drying treatment usually adopts two methods: hot air drying or natural drying. The appropriate drying method is selected according to the specific production conditions and raw material properties.
4 Pellet pressing
After the raw materials are dried, they will enter the pelleting process. This link mainly uses high-pressure compression to make the raw materials into granular form.
During the pressing process, pressure and temperature should be controlled to ensure that the produced biomass wood pellets have sufficient strength and stability.
5. Cooling section
The pressed biomass pellets need to be cooled to prevent oxidation reactions during storage. Cooling treatment usually adopts two methods: natural cooling or forced cooling. The appropriate cooling method is selected according to the specific production conditions and ambient temperature.
6. Pellet packaging
The classified pellets need to be packaged to prevent contamination or damage during transportation and storage. Packaging materials should be environmentally friendly and recyclable, such as paper bags, woven bags, etc.

Before choosing pellet mill plant equipment, companies need to clarify their own production needs. This includes considerations such as pellet type, production capacity requirements, quality standards, and production environment.
Avoid resource waste and low production efficiency caused by blind selection. It is crucial to choose an equipment manufacturer with independent intellectual property rights, R&D teams, and technological innovation capabilities.
It is also necessary to choose a manufacturer with complete quality inspection processes and equipment to ensure the reliability of product quality. In addition, a complete after-sales service system can provide timely technical support and maintenance to ensure the continuous and stable operation of the pellet line.

25 t/h pellet mill plant Process flow:
- Crushing: Large particle raw materials are crushed into small particles by a crusher, and then enter the next production link after crushing.
- Granulation: The crushed materials are transported to the granulator and pressed into granular shapes in the biomass granulator. The granulation process uses electric heating. The main working parts of the biomass pellet machine are the die and the pressure roller. The die wall is evenly distributed with film holes. The friction between the machine and the biomass raw material generates heat. The material temperature can reach about 70~110℃. The lignin contained in the raw material is softened and extruded from the die hole to obtain a solid molded fuel with a certain shape and specifications.
- Natural cooling: The biomass pellets after granulation are temporarily stored in the storage bin for natural cooling.
- Packaging: When the biomass pellets in the storage bin accumulate to a certain amount, they are manually packaged into bags.
- Finished products: After packaging is completed, the finished products are transferred to the finished product warehouse for temporary storage until they are loaded and shipped.

- Chipping: Use a chipper to perform primary processing of raw wood chips, and chip the raw materials on the original basis to meet subsequent processing needs;
- Crushing: The particle size of the chipped raw materials is still large and it is difficult to granulate. Use a crusher to further crush it to make it easier to process.
- Drying: The moisture content of raw wood chips is about 40%, which is not conducive to subsequent processing. Use a dryer to dry it. The drying itself only produces a small amount of water vapor; the dryer uses biomass pellets as fuel.
- Granulating: Use a belt conveyor to send the materials into the biomass pellet machine for granulation to make finished products. Rice husk is directly made into rice husk biomass pellet fuel through this process.

20-30 t/h pellet mill plant investment
The price of a biomass pellet making plant ranges from 270,000 – 1,600,000 USD. The investment size of a biomass pellet mill line is related to many factors such as the scale of the production line, equipment selection, and raw material sources, so it cannot be generalized.
Generally speaking, investment in a biomass pellet mill plant includes equipment purchase, raw material procurement, plant construction, operating funds and other aspects.
Equipment purchase is an important step, and factors such as equipment performance, quality, and price need to be taken into consideration. Raw material procurement is another key factor.
The price and supply stability of raw materials directly affect the operating costs of the production line. In addition, plant construction and operating funds are also investment costs that cannot be ignored.
- For small biomass pelletizing plants, the investment may be relatively low and suitable for start-ups or small-scale production.
- For large-scale pellet production lines of 20-30t/h, the investment scale is relatively large, and more factors need to be considered, such as financing, market demand, technical support, etc.
When investing in a biomass pellet mill plant, it is necessary to conduct comprehensive market research and risk assessment, and formulate reasonable investment plans and business strategies.
At the same time, it is also necessary to pay attention to factors such as the policy environment, technology development trends, and market changes to ensure the success and sustainable development of investment.
In short, the investment size of a biomass pellet line plant varies depending on the specific situation and needs to be comprehensively considered and evaluated based on the actual situation.
