complete biomass pellet machine line process flow

1.Raw material processing

The production of biomass pellets requires the use of wastes such as straw and wood chips as raw materials. Raw materials need to be preliminarily processed before production, such as removing impurities, foreign matter, etc.

Different raw materials are processed in different ways: for example, 2-meter-long wet straw needs to be cut, dried, and crushed; tree trunks need to be peeled, split, sliced, and crushed; bales of hay need to be broken and crushed.

2.Crushing and drying

The processed raw materials need to be crushed to facilitate subsequent granulation operations. The crushed raw materials also need to be dried to remove humidity and increase the hardness and density of the biomass pellets. Drying can be done by natural air drying or machine drying.


Granulation is one of the most critical links in the entire biomass wood pellet production process. Currently, biomass pellets are produced using ring die pelletizing methods.

4.Cooling and screening

After the granulation is completed, the pellets need to be cooled down to avoid deformation or cracking caused by excessive humidity or temperature. The cooled biomass pellets need to be screened to remove some fine particles to ensure the uniformity and quality of the pellets.


The final step in biomass pellet production is packaging. Pellets are usually packed into plastic or paper bags to protect them from moisture and dust.

Our team employs state-of-the-art tools and methodologies to map out your pellet machine line production flow and design a layout that maximizes productivity and minimizes waste. We specialize in optimizing every aspect of your biomass pellet manufacturing process, from raw material handling to workflow efficiency.

The goal is to better manage your resources—biomass materials, people, and processes—to streamline operations and significantly cut down on waste.

Equipment of 7-12T/H pellet machine line

Choosing the right pellet machine line equipment is crucial for pellet processing. When choosing, you need to make a comprehensive purchase based on various factors such as pellet type, production efficiency, and performance parameters.
